Handling of clipped input
Krzmbrzl opened this issue · comments
In mumble-voip/mumble#4391 we received reports of RNNoise leading to very distorted audio signals. After some further research we were able to trace the issue down to clipping input signals.
If such a clipping input is fed into RNNoise, the resulting audio is really badly distorted.
Idk what the best solution to this might be. A very simply solution could be to not perform any denoising, if the input is clipping as this seems to reliably worsen the situation significantly.
mumble-voip/mumble#4391 also includes audio samples (especially mumble-voip/mumble#4391 (comment))
