» Description
This package generates audio CAPTCHAs.

A CAPTCHA (see is a turing test to decide if a real person is accessing some resource and is typically a distorted image of some text. This package creates audio CAPTCHAS to help those who have difficulty reading this distorted text.

This package joins up multiple wav file recordings of individual letters/numbers being spoken, optionally adding distortion, creating an audio CAPTCHA.

The binary wav files are manipulated conforming to the well established wav specification. The default set of sound clips supports all passwords Text_Password can generate.
