[BUG] MP3 headers are malformed about rtlsdr-airband HOT 11 OPEN

Yes, I have noticed this as well but haven't looked into it because the audio seems fine / hasn't been a priority to look into.

Is this causing issues? If so, I wonder if the LAME parameter changes in #411 have any impact

FWIW I ran into this using both ffmpeg as well as trying to open files in Audacity (I used the work around here)

Not sure if that causes data loss or not, i do not have parallel samples from another source to compare.
If you can do first review pass on #411 to confirm the code is doing what we expect, i can try deploying it to see if that fixes the mp3 structure.

I've been grappling with an issue that may or may not be related to this. RTLSDR-Airband is capturing ATC traffic to mp3 files that rdio-scanner picks up (via dirwatch). The problem is that some of the recordings stop playback via rdio-scanner part-way through, and some don't play at all. Perhaps interestingly, the ones that stop in the middle always seems to do so at the point where there's an "over" in the conversation - i.e. ATC stops talking, then the aircraft starts, or vice-versa. If I download the mp3 from rdio-scanner, and play it with any other player, all of the audio is there. If I import the mp3 into audacity, re-export it as mp3, and drop the result in the dirwatch directory, rdio-scanner plays it OK. I tried applying the proposed "MP3 Quality" changes from #414, but that didn't fix it. I thought it might be something to do with VBR and periods of silence, but apparently not. My solution, for now, is to have rdio-scanner use ffmpeg to transcode the mp3 to h264/m4a, which seems to work.

I checked out recordings, and a lot of them cuts off words. Having said that, i do not have any concrete arguments to tie it up with malformed MP3 headers.

Most of recorded mp3 files are not playable directly from a web server using html5 audio component. When I tried to convert mp3 to ogg using ffmpeg, I got a lot of errors:

Header missing=N/A speed= 0x
Error while decoding stream #0:0: Invalid data found when processing input

from rtlsdr-airband.

Following - I really think this is causing many of the issue Im having. Since the headers are missing, icecast and perhaps the client is unaware what media format the audio is. With that being the case, there is a delay in the feed.

Can this be fixed?
