pyroomacoustics

2 1,344 5.8 Python

Pyroomacoustics is a package for audio signal processing for indoor applications. It was developed as a fast prototyping platform for beamforming algorithms in indoor scenarios.

Project mention: How would you classify impulse response and convolution? | /r/DSP | 2023-06-29

1) For the legal aspects, you could find some dataset with open licenses. Or, you could simulate the room impulse responses with a simulation tool like pyroomacoustics (disclaimer: I am the main developer).

C library for audio noise reduction and other spectral effects

Project mention: SoX noise reduction | /r/linuxaudio | 2023-07-12

https://github.com/lucianodato/libspecbleach is a marvelous denoiser. This library includes two example programs (with hardcoded parameters) that you can try as is or customize to your liking. adenoise_demo works without you specifying the section of noise, but the first half a second of recorded audio will be gradually less noisy while it adapts. denoise_demo learns the noise profile on the first 4096 samples and denoises the rest (so the output is 4096 samples short).
