C++ library for resampling audio signals
Zita-resampler is a C++ library for resampling audio signals. It is designed to be used within a real-time processing context, to be fast, and to provide high-quality sample rate conversion.
The library operates on signals represented in single-precision floating point format. For multichannel operation both the input and output signals are assumed to be stored as interleaved samples.
The API allows a trade-off between quality and CPU load. For the latter a range of approximately 16 is available. Even at the highest quality setting libzita-resampler will be faster than most similar libraries providing the same quality, e.g. libsamplerate.
