Using voice active system
The following picture shows how works the accu algorithm:
If signal is below the Attack Level for more than Attack Time, beginning of
that spot in the audio will be considered beginning of silence.
If signal is above the Release Level for more than Release Time, beginning of
that spot in the audio will be considered end of silence.
Silence Definition
For very quiet high quality audio, the Attack Level and Release Level value
will be lower (like -60dB). For noisier audio, the value may be much higher
(like -30dB).
If audio is above this given threshold for more than the number of milliseconds
given, audio will be considered valid, and not silence. Use higher values for
Release Time to ignore short periods of audio (like clicks, static, or other
noise). If this value is too high however (above 200ms), short words may be
skipped.
| Aucc Properties | Details |
|---|---|
| Attack Level | The level is in db. Varies from -92 to 0. the level of loudness for the starting point of recording. This is a level for non-silence detection. |
| Attack Time | Time is in ms. The sounding time for the starting point of recording. This is time for non-silence detection. |
| Release Level | The level is in db. Varies from -92 to 0. The level of loudness for the ending point of recording. This is a level for silence detection. |
| Release Time | Time is in ms. The silence time for the ending point of recording. This is time for silence detection. |
