RNNoise is a noise suppression library employing a recurrent neural network architecture. It aims to provide high-quality, real-time audio noise reduction while maintaining computational efficiency. The core problem addressed is the removal of unwanted background noise from audio signals, allowing for clearer and more intelligible audio.
RNNoise differentiates itself through its effective use of recurrent neural networks specifically designed for audio processing. Its design allows for efficient inference, making it suitable for real-time applications. The project provides clear instructions for training and deployment, along with options for model size optimization.
