#X text 35 327 Amplitudes of audio signals can have any reasonable
|
|
range \, but when you output a signal via the dac~ object \, the samples
|
|
should range between -1 and +1. Values out of that range will be "clipped."

its amplitude. You can also use the "*~" object to multiply two signals.

The "0" argument here instructs it that we'll just send it messages

to set the multiplier.;

#X text 35 396 Here we calculate a gain for the multiplier (*~) using

|
a "dbtorms" object (acronym for "dB to RMS"). 100 dB is normalized
|

to one \, and zero dB artificially outputs a true 0;
