12 [I] A Sample Rate Converter library for audio
14 [T] Libsamplerate is a Sample Rate Converter for audio. One example of where
15 [T] such a thing would be useful is converting audio from the CD sample rate
16 [T] of 44.1kHz to the 48kHz sample rate used by DAT players.
18 [T] Libsamplerate is capable of arbitrary and time varying conversions; from
19 [T] downsampling by a factor of 12 to upsampling by the same factor. Arbitrary
20 [T] in this case means that the ratio of input and output sample rates can be
21 [T] an irrational number. The conversion ratio can also vary with time for
22 [T] speeding up and slowing down effects.
24 [T] Libsamplerate provides a small set of converters to allow quality to be
25 [T] traded off against computation cost. The current best converter provides
26 [T] a signal-to-noise ratio of 97dB with -3dB passband extending from DC to
27 [T] 96% of the theoretical best bandwidth for a given pair of input and
28 [T] output sample rates.
