FFMPEG change Tone Frequency (Pitch Audio)












0














How can i change the Tone frequency.
This Example only pitch it by keeping the old tone frequency and only decrease the length of File.



For Example i have a constant 100 Herz tone (as mp3) and i want it to change 90 Herz



 ffmpeg -i 100h.mp3 -af atempo=100/90 90h.mp3


This Example not works for me, it sounds same



inputfile Mp3
outputfile Mp3

Basic method is



ffmpeg -i 100h.mp3 -af asetrate=44100*0.9,aresample=44100 90h.mp3


where 44100 should be replaced with the input sample rate.

    finally this works by keeping also the audio length



     ffmpeg -i test.mp3 -af asetrate=44100*0.9,aresample=44100,atempo=1.1 output.mp3
