No fast pitch-shift ratios could be computed for the given sample rate and transpose range.

See original GitHub issue

I use PitchShift wih min=-0.9 and max = 1.1, then it raise No fast pitch-shift ratios could be computed for the given sample rate and transpose range.. I dont face with this error when use cpu version github. Do you have any plan to fix it?

That’s an interesting use case, AliKarimi95

Note: Although the pitch shift transform in torch-audiomentations can be comparatively fast on GPU, it is slow on CPU. When running pitch shift on CPU, the one in audiomentations is roughly 3x as fast.

Pitch shifts are generally pretty intensive operations so I’m not too surprised about the increase in execution time. Regarding speed issues with some pitch shift factors, unfortunately some factors aren’t ideal for speed, so the rate of data transfer to the GPU becomes the bottleneck. In your specific case, it may be better to apply cpu-based pitch shift instead.
