Summary

A real time Equalizer for sound out.

Rationale

Equalizer basics

A equalizer is a tool that transform the sound in a defined way. The ways that the sound can be transformed is by changing the strenght (volume) of the sound in independent frequency bands.

One important aspect of a equalizer is how many bands there are, and how the frequency space is divided up in to a set of bands, ie which boarder values to use. Another important aspect is how many dB (decibel) it can turn up/down the sound.

Rationale

Why +/- 24 dB or more?

While people with normal hearing would probaly work out fine with +/- 12 dB, people with hearing loss that differ a lot betwen low and high frequencies will find +/- 12 dB too limiting. About 10% of the population suffer from hearing loss. This should be the description of why this spec is being defined.

Implementation

Should this tie in with PulseAudio (http://blueprints.launchpad.net/ubuntu/+spec/cleanup-audio-jumble)? - -- funkyHat 2007-01-20 18:02:42
