Beeper is an auxiliary audio processing AU and VST plugin which you can use to insert short beep, noise burst or silence signals to any sound material. This plug-in may help you protect your work from theft. It is safe to apply this plug-in to any mission-critical material because plug-in does not perform any processing on the audio between signals.You may specify signal's duration, beep frequency, signal's loudness, period between signals and random variation of all parameters.
