I have many MP3 audio files which are ADTS encoded. Unfortunately, my car radio doesn't support ADTS, so I need to convert them to normal MP3 files without a transport stream.
There are many people out there who asked the same question, but the only answers I found was converting to wav and then use
lameenc to convert it back to MP3
I'm sure there is a way to convert these files without decoding/reencoding them.
I already experimented with
avconv, but the parameter
-acodec copy doesn't seem to output anything different than ADTS.
I also played around with GStreamer. Funnily, I think it's the module aacparse which at least understands the format, but it's not a demuxer.
Which tool can I use for this?
$ file badfile.mp3 goodfile.mp3 badfile.mp3: MPEG ADTS, layer III, v2, 64 kbps, 22.05 kHz, JntStereo goodfile.mp3: Audio file with ID3 version 2.4.0
Update: I'm still testing, but it seems that 1) Also lame produces ADTS files and 2) ADTS is not really the problem for my car radio, it must be something different. I'm testing now with different profiles and bitrates, VBR and CBR. But it is still helpful if someone knows something more about ADTS.
