Freeverb3 是一个声音处理库，其中包括采样率缩放功能的一些修复的freeverb版本，NReverb延长执行CCRMA，对脉冲响应混响，FIR滤波器构造带分离器，softknee/hardknee限制器立体声增强。这个库的采样功能，提供高品质的音频效果，可用于无延迟的实时声音效果处理使用。
Freeverb3 is a sound processing library, which includes sampling rate scaling enabled version of freeverb with some fixes, extended implementation of NReverb by CCRMA, implementation of impulse response convolution reverb, FIR filter constructor, band splitter, softknee/hardknee compressor, softknee/hardknee limiter, stereo enhancer and many other filter and effects. Some of the filters in this library have oversampling feature, which may provides high quality audio effects.
The convolution reverb algorithm is highly optimized for x86 processors by using hand optimized codes of 3DNow!/SSE/SSE3/AVX/FMA/FMA4 (single precision), SSE2/SSE4/AVX/FMA/FMA4 (double precision), which can be used for zero latency realtime sound effect processing. This library supports any environment which GCC supports including x86/ppc/sparc.
