RNNoise: Learning Noise Suppression

[jmvalin]

This demo presents the RNNoise project, showing how deep learning can be applied to noise suppression. The main idea is to combine classic signal processing with deep learning to create a real-time noise suppression algorithm that's small and fast. No expensive GPUs required — it runs easily on a Raspberry Pi. The result is much simpler (easier to tune) and sounds better than traditional noise suppression systems (been there!).

Thanks a lot for your quick answer!
Regarding 2), I think I have to specify my question:

Looking at your training code (rnnoise/training/rnn_train.py), you feed the network with sequences of 2000 42-element vectors/frames (= 1 training sample). Now I wonder if two distinct training samples might share a certain number of frames?
