Unable to Play ADTS Formatted Audio Files

Audacity Help Forum Windows
1

Windows 7: 32- or 64-bit
Audacity installed via .exe file

I am unable to play .mp3 files formatted as adts. If I try to convert the file using Audacity, I get a very short but very high pitch output. However, when I use an online conversion tool to convert the file to a .wav file, I am able to play the newly created file with no issue. I have no problem playing .mp3 files in MPEG Audio format. Additionally, I can play the adts formatted .mp3 file on a Mac with no issue.

Does anyone have any idea as to what may be causing this?

You may be able to import ADTS files if you install FFMpeg http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown (I’ve not tested because I don’t have any ADTS files)

You will probably also need to set the “File types” filter in the Import dialogue to “FFMpeg-compatible files”.

Thanks Steve. I am actually more concerned with why I cannot play the track in the first place. I am not at home to test this but I will try it and get back to you.

As far as I’m aware Audacity does not support ADTS.
By itself, Audacity only supports a limited number of formats: WAV, Ogg, AIFF, FLAC, MP3 (import only) and a few less used formats, but Audacity can use FFMpeg to greatly extend the range of formats that can be imported and exported.

I installed the file you suggested but that did not change the result. I did not see any import dialogue. I simply clicked on Project → Import Audio. From there I imported the file. I attached a screen shot of the imported project for your reference. Note that the project is only .4 seconds long.

You are using an obsolete version of Audacity.
The current version is Audacity 2.0.3 and it is available here: http://audacityteam.org/download/

(in Audacity 2.0.3 the Import command is in the “File” menu)

FFmpeg only claims to support AAC in ADTS format.

After installing FFmpeg you may have to locate it in Audacity .

I was able to play the audio file by changing the extension from .mp3 to .aac. Unfortunately, no matter what I tried to do, I could not get Audacity to properly read either the .aac or .mp3 files. I have a few other conversion applications. I am going to investigate those. Thanks anyway.

After trying unsuccessfully to convert the .aac file using my other conversion software, I uninstalled Audacity and the FFMpeg installation and reinstall both using the steps outlined. Everything looks good. Thank you very much.
