Free and open source sample rate converter for audio libsamplerate is a Sample Rate Converter for audio. One example of where such a thing would be useful is converting audio from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT players. libsamplerate is capable of arbitrary and time varying conversions ; from downsampling by a factor of 256 to upsampling by the same factor. Arbitrary in this case means that the ratio of input and output sample rates can be an irrational number. The conversion ratio can also vary with time for speeding up and slowing down effects.libsamplerate provides a small set of converters to allow quality to be traded off against computation cost. The current best converter provides a signal-to-noise ratio of 97dB with -3dB passband extending from DC to 96% of the theoretical best bandwidth for a given pair of input and output sample rates.Since the library has few dependencies beyond that provided by the standard C library, it should compile and work on just about any operating system: Mac OS X, Linuxm, Windows, Solaris and more. What's New in This Release: · Fix a segfault which occurs when memcpy is passed a bad length parameter. · This bug has zero security implications beyond the ability to cause a · program hitting this bug to exit immediately with a segfault. · See : http://www.mega-nerd.com/erikd/Blog/2009/Feb/14/index.html · Thanks to David Cournapeau for the bug report.
