软件包：libspeexdsp1（1.2.1-1 以及其他的） [debports]
DSP library derived from speex
Speex is an audio codec especially designed for compressing voice at low bit-rates for applications such as voice over IP (VoIP). In some senses, it is meant to be complementary to the Vorbis codec which places a greater emphasis on high-quality music reproduction.
This package provides the runtime library of additional DSP functions that are part of the Speex distribution.
