Build: The README gives an autotools build sequence using autogen.sh, configure, and make.
CPU optimization: The project recommends AVX2 and describes AVX2 or SSE4.1 runtime CPU detection as build options.
Models: RNNoise can use its included default model or load a custom model from a file, filename, or memory buffer through its API.
Smaller model: The README describes an alternative little model with increased sparsity.
Training: Model training requires clean speech and noise data sampled at 48 kHz in 16-bit PCM format.
License: The repository identifies its license as BSD-3-Clause.
Support: Xiph directs people to its mailing lists or IRC channels for contacting the foundation and community.
