Data And Signal designed fast frequency detector which can detect frequencies in data frames of lengths as short as 2 milliseconds. It decomposes input signal into signal and noise space using linear algebra SVD. This allows for dramatic improvement in quality and performance over the standard Goertzel algorithm, commonly used to detect DTMF tones.

Our frequency detector is available as a dynamically linked module integrated into FreeSWITCH as DTMF detector and DTMF remover. more
