Projects / DTMF2NUM


DTMF2NUM is a tool for decoding DTMF and MF tones from PCM wave files. It supports any type of wave file, automatic optimizations (DC bias adjust and normalization), and both WAV and raw PCM data. The program has been successfully tested with many audio files, including ones that are highly dirty and damaged (for example, recorded with a microphone in a room or at very low volumes or with some noise).
