Smarc is a fast and high quality audio rate converter. It allows conversion between any samplerate. Smarc is a command-line program and a C library to be integrated in other applications.Featuressignal rate conversion between any sample rates.optimized for conversion between standard audio sample rates.command-line tool to convert audio filesC library to integrate smarc converter into other applications.Initially designed to convert audio, but also any 1-D signals such as EEG, seismic signals, etc.Convert sample rate using polyphase decimation and interpolation filters. This method guarantees high-quality for upsampling and downsampling.Internal filters can be tuned to emphasize speed or quality.
... For others ratios, the decompostion is automatically computed but the result is often not optimaland a manual help is recommanded, in this way one can manually defined a better decomposition.
