Secret Rabbit Code

Secret Rabbit Code is a sample rate converter for audio. It is capable of arbitrary and time varying conversions. It can downsample by a factor of 256 and upsample by the same factor. The ratio of input and output sample rates can be a real number. The conversion ratio can also vary with time for speeding up and slowing down effects.

            Just the right thing!
            When looking for a streamlined and easy-to-use audio resampling library to use in your project, you just found it!

            Resampling can be done either on a single block of audio data at once or, for streaming purposes, in smaller chunks of data, while libsamplerate takes care of managing the state.

            Good work!
