Kiss FFT is a very small, reasonably efficient, mixed radix FFT library that can use either fixed or floating point data types. http://sourceforge.net/projects/kissfft - 外文   7.BruteFIR BruteFIR is a software for applying long FIR filters to multi-channel digital audio, either offline or in realtime. Its basic operation is specified through a configuration file, and filters and attenuation can be changed in runtime through a simple command line interface. The FIR filter algorithm used is an optimised frequency domain algorithm, partly implemented in hand-coded assembler, thus throughput is extremely high. In realtime, a standard computer can typically run more than 10 channels with more than 60000 filter taps each. 说明文档:http://www.ludd.luth.se/~torger/brutefir.html http://freshmeat.net/projects/brutefir/ - 外文   8.TI 的DSP开发网站,强烈推荐.
