Hi, i recently looked into an mp3 file.
It contained the string with arguments is was encoded with. It looked like: -m j -V 0 -q 0 -lowpass 22.1 --vbr-mt -b 32
I looked into ffmpeg documentation and saw there's an argument "-cutoff" that should do, what "-lowpass" does in LAME.
I encoded some files with ffmpeg playing with the cutoff argument and saw no change in the resulting file.
When I used "-c:a aac" instead of "-c:a libmp3lame" cutoff had an impact. I looked at the mp3/m4a file with a tool "Spek" that draws a graph of the frequencies used in the file.
I now wonder why the argument is not passed to the LAME library?
