An audio file, whoes param is: 48k, 2 channel, 16bit.
The audio is sine wave and only has one frequecy: 19500Hz.
I use the this command:
ffmpeg -i 195khz.wav -b:a 384k -c:a mp2 195.mp2
ffmpeg -i 195.mp2 195-re.wav
The problem is: the high-pitch sine wave from original audio is eliminated
and all data in 195-re.wav is 0 !
How can I use mp2 to encode high pitch audio?
