BasicDSP is an educational tool that makes it easy to experiment with simple Digital Signal Processing algorithms for audio signals. The input can either be taken from the sound card, or be a locally generated sine wave, white noise or impulse signal. The output is fed to the sound card, as well as to a virtual oscilloscope and spectrum analyzer. WWW: http://wwwhome.cs.utwente.nl/~ptdeboer/ham/basicdsp/
