The following schema describes how to use the audiopreproc
module to identify DTMF dial tones.
[DtmfAudioNet] 0 = a ← wav(MONO, input) 1 = d ← audiopreproc(T,a) 2 = output ← wout (_, w:d)
0 |
The wav module processes the mono audio. |
1 |
The audiopreproc module in DTMF identification mode (T ) processes the audio (a ). |
2 |
The wout module writes the DTMF label information (d ) to the output file. |
