AAX to MP3 Reviews

No chapters, but that still much, much better than nothing!

Worked perfectly for me. All I did was read the "readme.md" file and follow its directions. I would like to thank the author very much for their work. I very much prefer "Smart AudioBook Player" to Audible's Android app, and AAX to MP3 is the simplest means to obtain an .mp3 in order to use this app.

Produced nothing but stuttering noise! Of course, the GUI is in German, which I can't read, but even so it seemed obvious how to use it. The output mp3 file seems plenty large enough (just a few percent smaller than the input .aax file), but upon playback in any player, all that was heard was a low-level, low-frequency stuttering noise.

This is not working for me. The "converted" files are 1kb and don't play. Can someone explain why? I downloaded and installed MS C++ Redistributable 2010 also. Using Windows 10 if that matters. Tried out the Aimersoft or TunesKit aax to mp3 programs, they aren't free and the trial versions can only convert <5 minutes of audio.

Awesome. Working with Audible like a charm. Tried to install iTunes and VirtualCD first, that's much too complicated. Thanks for the awesome work!

It seems my files are in AA format not AAX format. Any way to convert these with this program?

@godlich: the audiobooks are encoded at 64kbit, aaxtomp3 uses 128kbit resulting in doubled file size. @sammy789900: have a look at the command line app in ticket 4 - supports setting output bit rate and supports splitting into chapter files. don't expect much improvement by setting a higher output rate though - since input is at 64k you won't gain much quality.

Very helpfull but I missed a Function to change the Qualität to 192kbs or higher. I splitt the mp3 Files with Audiobookcutter

Very good and useful software. But why does it almost double the filesize compared to the aax? Is this normal?

This little tool is really great! Works without any problem. I especially like the experimental version that cuts the mp3 into chapters. Hopefully this feature will find its way into the main project.

Why does the mp3 sound like out of tune radio? Pls I need help. Thanks in advance. My rating is not final.

great app, thanks

Great piece of software! Simple and working - although on Windows 8.1 I had to follow maxfridbe's very helpful hint to install MS C++ Redistributable 2010 (s.b.). Now it works like a charm. An audiobook of about 21 hrs (rather long, compared) took about 1 hr to convert. (This a 2,6 Ghz CPU, running at 90% - older pc, as it were.) Thanks!

For those of you on win8 where this isnt working install: ms vc++ 2010 x86 redistributable package from microsoft

I am soo thankfull.. this is so wonderfull and easy to use im crying right now because i have screwed around with itunes and other s***ty software for so many hours.. and now this just..does what i want without taking hours and giving me nothing but errors im so happy x3 thank you so much!

Just great!!! Thanks a lot! Have to looking for this for way too much time!

Great work! I'm only wondering why the converted MP3 file is approx. twice the size of the original aa(x) file!?

Excellent and Easy to Use - Thank you! Vielen Dank! Worked on first try with no issues. Sound quality equal to Audible file. This solved a problem after other attempts failed. Many thanks!

Just wanted to thank you for this app. Spent hours yesterday trying to find something that would change my Audible files (that I'd already paid for!) into a format I could use on my phone, without forking out fifty dollars for software. Works great.... fast, simple and free. Awesome.

Did the trick, but I want to thank Vance003 for the hint to swap out the 64-bit ffmpeg. Before I did that, it crashed and I'd almost given up, but after I downloaded the right one and plugged it in, this app worked smoothly and well. However, by "smoothly and well," I mean that it took all night on my low-powered laptop for a 420Mb audiobook. This is not something to undertake lightly, but it is a fabulous solution to a problem I've been grappling with for the last 2 years. Once AAX2MP3 was finished, I used the free version of Audiobook Cutter to break the resulting mp3 into manageable 30-minute installments. (You can select the length, from 10 minutes upwards.) Thank you for an awesome tool!!!

Works real nice. Note that "opening" the file in Audible Manager means it needs to actually play the book. Before that it will not work.

works great, source code would be much appreciated...

WINDOWS 10 UPDATE: Although this program initially ran great for me under Windows 7, it does not appear to function under Windows 10. It spits out only a few bites of info before closing. If you're piping the output to ffmpeg (as described below), ffmpeg does generate an error message, but the fault seems to lie with how aaxtomp3 interacts with Win 10. Hopefully the author can uodate it, because it really is a fantastic program. ORIGINAL POST: This is a nifty little program because it is able to convert DRM-shackled aax files to liberated mp3 ones, and it does it much, much faster than just about any other converter around. There is no documentation, and the buttons on the program are in German --- but come on now! If you were smart enough to track down this little gem, you're probably smart enough to figure out how to use it. (A hint: the top button lets you choose the file, and the bottom button starts the conversion.) It does however lack a few needed features: the ability to batch convert files, and the ability to transfer metadata (or "tags," such as Artist, Title, Cover Art, etc.) to the new file. A few notes: 1) A previous poster said that it used a patched version of ffmpeg. I don't think it does. I think this is an off-the-shelf version, without modification. 2) It is, however, a 64-bit version of ffmpeg, so if you're using this on a 32-bit system, you need to go over to www.ffmpeg.org and download an appropriate version for your system. 3) It looks like this will only run on a system that you have previously authorized an Audible account on. It runs just fine on my home computer, where I have Audible Download Manager installed, but it produces a garbage file on my work computer, where I don't have Audible. This probably means you can't expect this crack the DRM for a file you don't otherwise already have access to. Sorry, pirates. 4) As noted by a previous poster, this can be run from a command line using the command: aaxtomp3.exe -i <aax file> | ffmpeg -i pipe:0 <mp3 file> Type that all on one line, as the output of aaxtomp3 serves as the input for ffmpeg. 5) The program ffmpeg is pretty sweet, and if you fiddle with that command line, you can get other sound files to be generated, like m4a or ogg files, depending on your tastes. 6) While ffmpeg can handle metadata, aaxtomp3 doesn't feed to it any of the original aax metadata, so there's no solution there. Until version 2.0 of this comes out, I'm fiddling with other programs to try to get this ironed out. 7) Because there is this command line version, however, it IS possible to use this in a batch file to convert ALL of your aax files. I use: for /f "delims=|" %%f in ('dir /b ^| findstr /i /e .aax') do ( aaxtomp3 -i "%%f" | ffmpeg -i pipe:0"%%f.mp3" ) You can actually type all that on a single line in a batch file, if you want. This looks in the current directory for every file that ends in .aax, converts it, and appends .mp3 to the new file. So if you started with fubar.aax, you generate fubar.aax.mp3. Run the batch file and then kick back for a few minutes, or hours, or days, depending on how big your library is.

Works out of the box on my 64 bit Windows 7! It's lightweight and does what it says it will do. Source code would be nice!

Es scheint derzeit keine Möglichkeit zu geben eine MP3-Datei > 2GB zu erzeugen. Der Konvertierungsprozess stoppt einfach. Ist hier auf ein Update zu hoffen? Ansonsten ein echt cooles Tool! :-)
