Hi all, I need a down-sampled(=8kHz) version of my input.wav file (=16kHz).
According to https://trac.ffmpeg.org/wiki/FFmpeg%20and%20the%20SoX%20Resampler, I use the command below ffmpeg -i In16k.wav -af aresample=resampler=soxr -ar 8000 Out8k.wav It works well, but I found that every time I run the command above, it returns the "Out8k.wav" with a slightly different(in PCM value). The question is : *Is the difference I found a normal phenomenon? *If I want a resampler which always returns the same result, how can I do? Sorry about my poor English. Thank you all.
