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!).

Hi JMV,

In Amateur Radio noise suppression is always a big topic. I've added your project into a SDR receiver - if you're not into SDR see www.sdr-radio.com . Anyway it's working well when the audio is above the noise, when the noise and audio are both at the same level I can lose the audio.

This isn't a complaint - just an observation, your code isn't really designed for this situation. Now if only I could get you interested the Amateur Radio your skills would have a big impact on noise reduction.

Thanks for this project, I'll be following it closely.
