I work in speech recognition. I first noticed yesterday that I'm getting
different results than normal when using ffmpeg to convert an audio file
from mp3 to wav. When I use sox I get the same results as before, so there
must be some recent change with ffmpeg that is messing things up.
The command I'm using is `ffmpeg -loglevel error -i $1 -ar 16000 -acodec
pcm_s16le $2` with the sox equivalent being `sox $1 -t wavpcm -r 16000 -e
signed -b 16 $2`.
Would be nice to know what exactly is responsible for the difference.
