Libzita-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 1:6 is available. Even at the highest
quality setting libzita-resampler will be faster than most similar
libraries, e.g. libsamplerate.
