# Biquad Filter

### by Ricard Marxer

Applies a Biquad filter to an audio stream. Remember to Mute the audio to hear the pure filtered sound.

The filter implementation will become part of the dsp.js library.

You will need a recent build of Mozilla Firefox with the Audio API to hear the filtered version.
