To keep the pitch change while setting the preferred sample rate the filter aresample is needed, as seen below: $ ffmpeg -i input.mp3 -af "asetrate=44100*0.5,aresample=44100" output.mp3. As stated earlier in this question, for a true pitch to be applied the tempo shouldn’t change.

Or manually set the audio sample format. With the -sample_fmt option. ffmpeg -i input.wav -sample_fmt s16 -ar 44100 output.wav See a list of audio sample formats (bit depth) with ffmpeg -sample_fmts; Or use the aformat filter ffmpeg -i input.wav -af "aformat=sample_fmts=s16:sample_rates=44100" output.wav
How to use FFMpeg to do Simple Audio Conversion
https://www.howtoforge.com/tutorial/ffmpeg-audio-conversion/
Suppose that we want to determine the bitrate for the output file. To do this you need to enter it in the following way: ffmpeg -i filename.aif -b:a 320000 newfilename.mp3. Note that the bitrate is measured in bits/sec so if I want 320kbit/s I need to enter 320000. Here's my example:

https://superuser.com/questions/253467/convert-an-mp3-from-48000-to-44100-hz
ffmpeg doesn't look to be the appropriate tool; I'd normally use sox for audio-only files. $ sox file1.mpg -r 44100 file1-enc.mpg If you want to try using ffmpeg anyway, I think the correct command would be $ ffmpeg -i file1.mpg -ar 44100 file1-enc.mpg
