Description

Adaptive Digital’s Arbitrary Tone Detector software detects user-defined tones. The goal of any tone detector is to rapidly identify the presence of a specific tone, the Arbitrary tone detection software finds use when the user needs signaling tones other than the standard DTMF and MF tones.

The Arbitrary Tone Detector software is capable of handling multiple simultaneous channels. For the tone detector, this means that each instance of the detector can be detecting tones in a different stream of data
