1 Description

+ +

The libswresample library performs highly optimized audio resampling, +rematrixing and sample format conversion operations. +

Specifically, this library performs the following conversions: +

Resampling: is the process of changing the audio rate, for +example from a high sample rate of 44100Hz to 8000Hz. Audio +conversion from high to low sample rate is a lossy process. Several +resampling options and algorithms are available. + +
Format conversion: is the process of converting the type of +samples, for example from 16-bit signed samples to unsigned 8-bit or +float samples. It also handles packing conversion, when passing from +packed layout (all samples belonging to distinct channels interleaved +in the same buffer), to planar layout (all samples belonging to the +same channel stored in a dedicated buffer or "plane"). + +
Rematrixing: is the process of changing the channel layout, for +example from stereo to mono. When the input channels cannot be mapped +to the output streams, the process is lossy, since it involves +different gain factors and mixing. +

+ +

Various other audio conversions (e.g. stretching and padding) are +enabled through dedicated options. +
