noise-repellent is a suite of lv2 plugins for noise reduction that uses the libspecbleach library, which is written by the same developer.
libspecbleach is C library for audio noise reduction and other spectral effects. It uses the concept of a spectral processor which itself uses a short time Fourier transform (STFT) to process the audio. Several techniques are implemented in the library that are being used in the denoisers, such as masking thresholds estimation, onset detectors, etc. All these are being used in conjunction to improve the very basic spectral substraction algorithm.
This is free and open source software.
Key Features
- Adaptive noise reduction plugin for low latency voice denoise.
- Manual noise capture based plugin for customizable noise reduction.
- Adjustable Reduction and many other parameters to tweak the reduction.
- Option to listen to the residual signal.
- Soft bypass.
- Noise profile saved with the session.
