How can I convert .AA files to MP3 audio files?

Update: May 14, 2016.   Well, ten years later and this Free method to remove DRM from Audible AA files and convert to MP3 still works.  The links to the necessary files in the post below are still valid.   Please feel free to contact me through the comment section if you need help.

Use these simple instructions to easily convert audible .AA files to (non-DRM) MP3 files so that you can play the MP3 files on any MP3 player. This article describes where to get the special file you need to perform this easy audible .AA conversion to MP3.  [As of May 2016,  you will find Goldwave 5.52 and other versions at this link

Goldwave, is simply an audio conversion program. It requires the audible Codecs to perform the conversion, but is not distributed with them, so the audible Manager software must be installed before Goldwave can open an audible .AA audio file.

UPDATE: Newer versions of the audible and Goldwave programs have been released since I last revised this article a few years ago. So, here is one important distinction between the old instructions and the new instructions: You must to install an obsolete audible file called “audibleMediaPlayerFilter.exe This is the “secret” of this method and your conversion won’t work without audibleMediaPlayerFilter installed. You can use a search engine like Google to search for “audibleMediaPlayer.exe” or you might be able to download it from this link.

UPDATE: Important notes about the audible Manager software: This method to convert audible .AA files to MP3 was successful with audibleManager version which was the latest version as of 5/22/2009. It also worked with every other version of audible software I tried and I suspect it will work with all versions of audibleManager software. When installing the audible software, be sure to select audible’s “Listen on my Computer” option so that the correct files are installed by audible for the Windows Media player. If you’re able to listen to your audible files in the Windows Media Player, then your audible Manager is installed correctly.

UPDATE: Important notes about the Goldwave software: This method to convert audible .AA files to MP3 was successful with GoldwaveaudibleManager version 5.52 which was the latest version as of 5/22/2009. However, the recent versions of Goldwave are “demo” versions that require payment after a certain amount of time or a certain number of times used. You may want to search the internet for “Goldwave 5.06” which is an older full version that never expires. You may want to archive (back up) the Goldwave 5.06 installation program in the event you need to reinstall it in the future.  [As of May 2016,  you will find Goldwave 5.52 and other versions at this link]

The original article (with updates) begins here:I have an old audible account that I’ve not used for a couple of years, so I logged into my old account then downloaded and installed the audible manager software, which did the job of installing the audible “.aa” codecs on my computer. I used my user ID and password to start the audible Manager software. Important: You will need to note the computer folder to which your audible .AA files are downloaded: From the audibleManager menu, click”Edit” then “Options” to display a dialog that includes the “Location of Audio Files.”
1) From audible, I downloaded a copy of the audiobook “Next,” that I had purchased a few years ago. When the download was complete, I completely closed the audible Manager software.


2) I then started the Goldwave audio conversion software and I performed a “File|Open” command to load the audiobook (.AA) file from the audible download directory. Remember: from the audibleManager menu, you can click”Edit” then “Options” to display a dialog that includes audible’s “Location of Audio Files.” Reminder: This is the “secret” of this method it that you must find and install the obsolete audibleMediaPlayerFilter file. You might be able to download it from this link.



3) Be aware that Goldwave (may require the ID and password of the audible user who originally purchased the file before it can be opened. After you convert the file to MP3, however, you can play the MP3 file on any device without entering the audible ID and password.


4) After successfully loading the audible (.AA) file into Goldwave, I selected “File | Save” then used the drop downs to select a target MP3 format file with a setting of 128kbps and a sample rate of 44100. Goldwave successfully wrote a new MP3 file to the target directory. It took Goldwave about 35 minutes to convert my 6 hour, 42MB, .AA audio file to a single large MP3 file.

UPDATE 5/2009: The first time you use Goldwave to convert an audible .AA file to .MP3, the following error may be displayed: “Encoder not found. A recent versionto the MPEG Layer 3 encoder LAM MP3 cannot be found.” The “LAME” encoder is a free file that many sound programs use to create MP3 files. You can usually click the “download” button (displayed with the Goldwave dialog) to download and correctly install the LAME MP3 file.



5) I used a program called, “MP3 DirectCut” to slice large single MP3 files into 10 or 15 minute segments. Update: thanks to “JLC” who posted this great description of how to use the Goldwave program to divide the MP3 file into separate tracks during conversion without using MP3 Direct Cut.

  1. I’ve head of other people having success with this method. But I still haven’t gotten it work. I’ve got the latest audible manager and a pretty recent Goldwave. I can’t open the aa file. (BTW first you have to change the file type to “all files.”) The file is processed to 4%, then it quits and the program hangs up. Rick

  2. I used to open .aa files and save them as .mp3 files all the time. Now when I try, Goldwave tells me that it can’t recognize the file format. When it used to work, it would automatically launch the codec but now it doesn’t… it just gives me the message that it can’t recognize the format.

    Any ideas what might have happened? Others seem to have success with the latest Goldwave and the latest codec.

  3. Hi, this may sound strange, but I would like to know if there is a way to convert an audio book in mp3 format to audible audio format. I just bought a nuvi and would like to use some of my older multi file mp3 books on there. Thanks.

  4. You can use the Goldwave program to divide your audible files into tracks while it’s doing the conversion. I prefer this method instead of using something like MP3 Direct Cut because Goldwave makes gapless tracks. The tracks play back with no pause between.

    To do this, follow the first three steps above. In step four, instead of doing the File|Save, click on Options, then on File Format. Now, click on the Default Save Format tab and select the format you want, MP3, WMA, etc. In the attributes box, select which attribute you want and then make sure to check the “Use this format for Save As, Save Selection As, and Copy To” box. The Auto Cue setting discussed next won’t work unless you set the Default Save format first.

    Now, click on Tool, then Cue Points, then Auto Cue.
    Select the Spacing tab. The “Starting at time” should be 0.00. In the Interval box, select the length you want your tracks to be. (Please note, 1.0, 2.0, 5.0 etc. are seconds, not minutes! Five minutes is shown as 5:00.00, thirty minutes is shown as 30:00.00. One hour would be shown as 1:00:00.00.)

    Click on OK and the Cue list will be shown. Now, click on Split File. In the Destination Folder, browse to where you want the file to be saved. In the “Base filename” box, it will show track# or track##. The number of number (#) signs is how digits will be in the track number. If you will have 9 or less tracks, you should have track# in that box. If there will be 10 to 99 tracks, it should be track##. One hundred or more would be track###.

    In the “First number” box, you can put whatever number you like and that will be the track number for the first track. (This is handy if you are converting a two part book. If the first part comes out with 6 tracks, you can start the numbering for the second part at 7 so you will maintain the proper numbering.) When you are done, click OK and Goldwave will start processing the tracks.

  5. This post uses the information gleaned from other posts, I hope it helps.

    In order to use Goldwave (Google: gmwave506.exe)to convert .aa from Audible files:

    1. Uninstall Audible (current version blocks conversions)
    2. Install the Win98/ME version (old version, works fine in XP)- It appears that Audible no longer has this file available on their site that I can find. Search google for it. (AM_CDBurner.exe)
    3. Uninstall Goldwave 5.x
    4. Install Goldwave 5.06 (Google it, I downloaded from
    5. Open Goldwave
    6. Choose All Files (of type)
    7. Navigate To Your .aa File
    8. Open It
    9. Enter Your Username/Password To Activate The File (if required)
    10. Watch As It Converts

    The above steps worked for me. And whats great about GoldWave is that it Batch processes everything all at once. If you have a Zune you just need to change the file tag to Podcast for it to remember last pause point automatically.

  6. The following torrent link contains an entire package for converting aa to mp3 as well as some helpful tools for organizing audio (or any) mp3 files:


    Assuming you have a bit torrent client like uTorrent or some other, the link will allow downloading the torrent for the package which contains:

    Audible Manager 3.5.exe (An older version that works fine with Goldwave)
    gwave508.exe (An older version that can convert the .aa files
    to mp3 or nearly any other format)
    lamewin32.exe (The latest mp3 codec – works with Goldwave)

    And some icing on the cake:

    RenameMaster.exe (My favorite file renaming utility)
    TagRename34.exe (An excellent ID3 tag editor)

    This is available as of 2-6-08. May not be available after a month or two.

  7. BTW – SoundTaxi works but takes FOREVER!!! I mean hours to convert a 100Mb+ file (and I’m running a 3GHz with 2Gb mem).

    Goldwave is very fast at converting aa to mp3. It’s also very EASY to auto-cue large files at, say 15 or 20 minute intervals, and split it into mutiple files at the cue points. It also has automatic incremental file renaming of the split files. You determine the intial base file name you want and tell it how you want the numbering to increment. It takes care of the rest – plus, it remembers those settings and will default to them the next time you split a file. You just change the filename and storage location to suit. Converting a 100 Mb plus file, splitting and saving into 20 minute segments, takes all of about 10 minutes. It takes you all of about 1 minute of actually being at the computer (assuming you’ve already downloaded the aa file from

    Also, refering to the last post, if you had an old version of Goldwave working before and made THE HORRIBLE mistake of upgrading your Audible Manager to the latest version (not sure which version number is the cutoff) you found that Goldwave could no longer open their creepy aa files. The download package referred to in that last post takes care of this issue. You just un-install your current (mistake) version of Audible Manager and install Audible Manager 3.5 included in the torrent download. Wolllahh! You’re back in business! Now – DO NOT EVER UPGRADE AUDIBLE MANAGER AGAIN!!! EVER!!!

    One last thing: Even though is being kind of a pain in the butt with their aa weirdness, after you have the mp3 conversion, DON’T screw them by putting it out on the net or giving it away to all your friends. Audible provides a useful service and deserves to have their material protected from free distribution. Put yourself in their shoes. Just use the mp3 instead of the lame aa and let the enhanced listening freedom that the mp3 provides be enough.


  8. It seems Audible may have finally caught onto the trick of using an older version of their software to download .aa files for conversion. I’ve been using AudibleManager 4.0 to download my audiobooks and then was using DBAmp to convert them to .mp3, and this worked as of last month. Yesterday, I went to download a few new books and my AudibleManager bombed, saying that it was “unable to load parameter file”. I went to Audible’s website, and they say the way to fix this is to upgrade to latest version of their software (which blocks the converter apps)! I’ve tried several other old versions of the Audible software I found on the net as well, and they’re all displaying the same parameter error. I also tried the new downloader from the Audible site, which of course works just fine to get the audiobooks, but also prevents the converters from working correctly. Has anyone run into this beside me? Know how to fix the “unable to load parameter file” problem?

  9. JLC, you say Goldwave will produce gapless tracks. On what medium? If I play back the tracks produced by GW in WinMedPlayer, they do play seamlessly and even if words were split, it’s not detectable.

    However, when I burn a CD with the MP3’s, there is a pause between tracks which causes works to be interrupted for a second or so, and it gets irritating after a while.

    I’m trying to figure out how I can burn these tracks to a CD without a gap. Roxio won’t do it. Any ideas?

    Are there any freeware applications out there that will split a large mp3 file into tracks based on pause detection. I haven’t found a freeware version yet.

    I’d like to hap gapless tracks so that if I remove the CD from the player, I can easily find where I was when re-inserting the CD.

  10. You can download the aa file on one computer with the latest Audible Download Manager software and then copy the .aa files to a computer set up as described above.

  11. try reinstalling the old manager after getting the new book and uninstalling the new AudMan maeby it will work, dunno.

    i do know that the kit from afterdawn works like a charm

  12. Im using the current version of Audible, and the current version of GoldWave with no issues at all. However you will need both the msvci70.dll and the AudibleMediaPlayerFilter.exe

  13. All this special software configuration and setup.
    Recommendations that you download using one computer
    and then convert using another? Argh!!!

    I think I will finally start using some kind of virtual machine (VM) software. Now, I have Vista Ultimate 64 bit edition on my 4-core AMD Phenom. So I have to check
    to see if I am licensed to install the 32-bit version on
    a VM. Lots of stuff only works on 32-bit anyway.

    I am already running Ubuntu 8.10 on that machine under
    Microsoft Virtual PC.

  14. DBPowerAMP 100mg audible file converted in than 13min 45 seconds.

    SoundTaxi same 100mg file converted in in 15 min 32 seconds, BUT if your a Vista user you will triple this time or even higher, from now on its just the OS who will not be named to me.

  15. As the music in iTunes is encrypted with DRM, you cannot directly put it on any non-Apple MP3 player. The easiest way is:

    1. Insert a CD-R or CD-RW disc into your CD-ROM drive.
    2. Burn your playlist to make an audio CD.
    3. After the audio CD is successfully burned, insert the disc into your CD-ROM drive again. Then you can use iTunes to import the music tracks on the burned disc as MP3 files.

    Or you can get some software to help you. I use TuneClone M4P Converter ( ) to do this. Though not free, it is very well worth a try. It generates a virtual CD drive to help to remove DRM from iTunes.

  16. mp3directcut has pause detection.
    You specify the length of the pause to detect and the minimum length for the parts (you simply tell mp3directcut how many seconds to skip after a pause was detected before ist starts looking for the next pause).

    Simply try it. It’s free:

  17. I use SoundTaxi on a Vista Core Duo 2.0 gHz machine with 4gb RAM. It has worked great in batch mode, converting up to 10 files at a time, at an average rate of about 50 minutes per file — and these are book files, most of them 6 to 8 hours long. Converting a single file at a time is slow, at least a couple of hours, but on the flip side it’s no drag on my computer so I can do other things while it converts essentially in the background.

    For installing the software under Vista there are two key points. First, you must DISABLE remote desktop. To do this, enter “system” in the search box on the start menu, choose “system” from the options, and click on the line at the left that relates to remote desktop. Second, disable your antivirus during the course of the installation. I first installed SoundTaxi without doing these two steps and the software would not work. However, after an irate email to the seller I got this advice and it worked well.

    My vote is that SoundTaxi is a reasonable option, especially if you have a lot of files to convert. It has taken me about 5 days to convert over 170 Audible files to equivalent MP3’s. I’m not jumping for joy, but if I did the play-in-a-player-and-record-the-audio trick, the process would have lasted about 2 months, during which my computer would have been unusable.

  18. Hi everybody! Did anyone try the described GoldWave/AudibleMediaPlayerFilter.exe-method on Windows 7? It works perfectly on my WinXP machine, but GoldWave (the old version from the package) crashes when started on Windows 7. Any suggestions?

  19. Just adding my recent experience with Soundtaxi Professional (latest version) as I found this site by googling “Soundtaxi batch mode” while having problems getting more than one file at a time to convert.

    It works great as long as iTunes doesn’t get involved. Make sure Audible Manager is installed as the default player for your Audible files. If you have enhanced Audible format files (aax), Soundtaxi insists that iTunes is required. However if you change the file extension of your enhance format file to aa (regular Audible extension), it works just fine in batch mode by either specifying a folder to automatically convert or dragging multiple files over to the Soundtaxi window.

    Before I changed the extension my quad core with 8gb RAM would only convert one file at a time at 1X speed using iTunes to play. Now it will convert around 16 files overnight using the Audible Manager player.

  20. Should have mentioned above that I’m using Windows 7 Professional 64bit and thanks to Derek as his post for made me think about iTunes being the default player as an issue.

  21. I actually am using the two computer set up and moving the files over to covert them to the mp3’s. However, on some files (about 30%) I get an error when I try to open the file with GoldWave that there is “No Audio Content Detected”. Sometimes it even happens with the second part of a book after part 1 worked fine. I tried to delete the file and re-download from Audible without any luck. Any ideas?

  22. Thanks Lisa, I was able to reproduce your results with the new Audible Enhanced format using SoundTaxi. This finally seems to be a workable solution. I think it is actually using the Windows Media Player engine, not Audible manager to play the files though. I’ve been trying to move my everyday audiobook listening from my Cowon D2 (which doesn’t play the new aax) over to my new droid eris phone. I will probably still use the D2 for long travelling days though because of battery life.

    On the android platform I highly recommend AstroPlayer. It has very similar bookmarking capabilities to the Cowon D2 and developer updates the thing every week or 2. It even supports bluetooth stereo, which will be really cool once I get some headphones for that and an interface for my car.

  23. thanks for the instructions. I used the orginal set of instructions at the top of the page. it process worked but the the resulting mp3 file is just under 500 meg. the aa file was only 113 meg. is tehre anyway to reduce the size of that mp3 file?

  24. Worked for me. Windows 7 install following these instructions, and getting the exact versions posted (a Google search and you can find them – don’t get the latest versions).

    Note though that the required DLLs for the Audible install are no longer included with Windows 7 and later. You have to download them. You can get the two missing MSVC*70.DLL files from, as it’s where I found mine and scanned for virus’:

    I also snagged the required LAME_ENC.dll from there too:

    Place them in your C:\Windows\, and then follow the instructions above to install Audible and then GoldWave.

    Worked like a champ afterwards.

    TIP: GoldWave supports BATCH processing. I had 100+ AA files to convert. Just queue up the files, check the box for “Convert to”, select 128kbps MP3, and let it sit and crank for a while. Have a donut.


  25. Finally was able to find and download Goldwave 5.06 (wish I’d seen the more recent comments before that) and have installed it. I followed the instructions-steps, but the file that’s saved is just a lot of noise instead of the audiobook. Does anyone know what the issue is and how to fix it? Have spent hours on this now and it’s gotten very frustrating…


    (Also downloaded the said audibleMediaPlayerFilter but when I run it keeps “Error Copying Files”)

  26. down and dirty way will never fail…

    get free “Audacity” program (windows installers available for this excellent open source editor/recorder)

    if you want mp3 export you also need to DL lame.dll and put in same folder as audacity.exe

    after installed simple three step process
    1) set audacity to record master mix, and play your audio book
    2) when finished, stop audacity and export to your favorite audio format (ogg, flac, wav and MP3 if dll added)
    3) curse the time you allowed yourself to pay good money to bad Micro$hit enabling sites like

  27. I use the Goldwave method with a slightly different trick. I run Windows 7 Pro so the Audible filter cannot be installed thereby rendering the method unworkable. To circumvent this, I created a virtual XP machine. I installed Audible, iTunes and Goldwave on it. I then batch a dozen or so to run on the VM. It works seamlessly plus, by being on a VM, I don’t have issues with GW hogging all my RAM. It uses everything I have allocated for the VM, but that’s it. I can go about my business while all this is happening within a protected shell.

    BTW: You need to have Windows 7 Pro, Ultimate or Enterprise to use the MS Virtual Machine feature. It will also work with VMWare Workstation.

  28. I got soundtaxi to work. I’ve been using it for years with Napster. Even though I have Napster to go it wouldn’t work on my wife’s iPod. I now have an android which audible doesn’t support yet. Soundtaxi converted the audible .aa files fine. You do, of course need to have the proper drm license for the file for SoundTaxi to work.

    Any Android users out there I recommend Astro Player Beta for audio books. Best audio book player I’ve ever used. It will do bookmarks by play list. When you select a bookmark, it reopens the playlist first then goes to the file and time index of the file. I know… revolutionary idea… eh?

  29. Here’s a surefire way to remove DRM from Audible (.aa), Audible Enhanced (.aax) or any other format that allows burning to CD, but without using up CDs.
    Get a piece of software called Phantom Burner. It creates a virtual CD burner which you can then select in iTunes and burn your Audiobook/music to it. It saves the audio as .wav files which you can then convert to MP3 or MP4 using your favourite converter. I find foobar2000 good for quick encoding (right click on the files, convert, … and choose your settings).
    Audible Enhanced is actually 64kbps mono audio, although given the reasonable quality they achieve with this low bitrate it’s probably MP4-encoded with variable bitrate and 64kbps as the target bitrate.
    iTunes unfortunately ignores the bookmarks within Audible Enhanced and simply burns the file split into 8 minute tracks. Foobar2000 can be used to recombine into one very long output file, which you can then split up in the correct places if you have time.

  30. I’ve tried the Goldwave method, but can’t get it to work as it comes up with a message saying it “cannot determine the format of the file”. Any ideas? I’ve tried various options but just end up with lots of hissing after the conversion!

    Thanks, Andy.

    Answer: Typically when Goldwave can’t determine the format of the file, either you’re using the wrong version of Goldwave or you’ve not installed the “audibleMediaPlayerFilter.exe“ file. Please ve suer you’ve installed audibleManager version and Goldwave 5.06

  31. Worked perfectly. Thanks so much for updating! I bought an Audible book hoping to play it in the car but realized I couldn’t put it on my usb drive which holds my music. You saved me! Awesome!

  32. Hold it!!!!!

    What you do is install Noteburner (acquiring a license in the correct way of course)

    *google noteburner*

    This creates a virtual CD drive, and when Audible uses Nero to burn to CD, you select the new CD drive as the target.

    Noteburner then nicely converts it all to mp3 and places on your HD without ever going near a CD.


    NOTE: The Noteburner method requires a LOT MORE WORK. Noteburner is just like burning a CD, except you burn it to MP3 files on a hard drive. So if your Audible file is 12 CD’s then you’ll have to “Burn to (virtual) CD” *twelve* times.

    However, with the Goldwave method where you just tell Goldwave “convert the file to MP3” and walk away. You only take an action once with Goldwave which is easier than burning 12 real CD’s or 12 “virtual” CDs.

  33. I would like to add that Nero automatically includes all CDs for the project for the audiobook in question. So, once I click burn, Nero burns all CDs sequentially and adds them to the HD in order thanks to Noteburner. The only difference is that they are split in to smaller mp3s, about 7 mins each long. I would prefer the mp3 files were longer, but for the purposes of compatibility with all mp3 players (some of which don’t like playing mp3 files over 20 mins), this option may suit many people and it’s much easier to set up. In terms of time, I’m finding this option much quicker and less of a pain to set up and configure. But hey that’s just me 🙂

  34. Hey people, I`m not able to convert Audible Enhanced files with Sound Taxi (version 3.6.5). Audible Manager is the default application for the .aax and .aa files and not iTunes but Soundtaxi still doesn`t recognize the files.

    Any ideas?
