silence in the audios

[Thomcle]

When I stretch an audio with a ratio different from 0.5 in the interval ]0; 1[ the audio size is indeed accelerated but the duration doesn't change. For example when do that in python:

stretch_audio("input.wav", "output.wav", ratio=0.7)

The output.wav file has the same duration as input.wav, but the beginning is correctly accelerated. There is a silence to fill it.

I plot a graph with the ratio on the x-axis (here there was a 0.1 difference between each calculation) and the time on the y-axis. You can see that there are steps and that the duration doesn't change for "special" values :

Same error occured with me, any solution ?

What I did was I cut the end of the audio from the initial duration and ratio. It's not really a problem
