61 (synopsis "Reading and writing files containing sampled sound")
63 "Libsndfile is a C library for reading and writing files containing
64 sampled sound (such as MS Windows WAV and the Apple/SGI AIFF format) through
65 one standard library interface.
67 It was designed to handle both little-endian (such as WAV) and
68 big-endian (such as AIFF) data, and to compile and run correctly on
69 little-endian (such as Intel and DEC/Compaq Alpha) processor systems as well
70 as big-endian processor systems such as Motorola 68k, Power PC, MIPS and
71 SPARC. Hopefully the design of the library will also make it easy to extend
72 for reading and writing new sound file formats.")

92 (synopsis "Audio sample rate conversion library")
94 "Secret Rabbit Code (aka. libsamplerate) is a Sample Rate Converter for
95 audio. One example of where such a thing would be useful is converting audio
96 from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT
99 SRC is capable of arbitrary and time varying conversions; from downsampling by
100 a factor of 256 to upsampling by the same factor. Arbitrary in this case means
101 that the ratio of input and output sample rates can be an irrational
102 number. The conversion ratio can also vary with time for speeding up and
103 slowing down effects.
105 SRC provides a small set of converters to allow quality to be traded off
106 against computation cost. The current best converter provides a
107 signal-to-noise ratio of 145dB with -3dB passband extending from DC to 96% of
108 the theoretical best bandwidth for a given pair of input and output sample
