Hello,
In the Speech Dispatcher configuration template, there is sox called with the argument norm
|
PROCESS=\\'sox -r SAMPLE_RATE -c 1 -b 16 -e signed-integer -t raw - -t wav - tempo \$RATE pitch \$PITCH norm\\';\\ |
In the doc (man sox), there is :
norm [dB-level]
Normalise the audio. norm is just an alias for gain -n; see the gain effect for details. gain [-e|-B|-b|-r] [-n] [-l|-h] [gain-dB]
Apply amplification or attenuation to the audio signal, or, in some cases, to some of its channels. Note that use of any of -e, -B, -b, -r, or -n requires temporary file space to store the
audio to be processed, so may be unsuitable for use with `streamed' audio.I tested to remove the norm, it seems that the output is faster
