Hey PD-List,
Has the throw~/catch~ system been designed to have a different available
headroom than standard [+~] and [*~] objects?
I've been designing a few polyphonic patches and have decided to use
throw~/catch~ instead of hard-wiring the summing bus. I've found that
when the signal approaches 1.0, distortion occurs. Has this been
designed as such for a reason?
Yes, [throw~] and [catch~] and all the other dsp objects can handle
signals up to the limits of the float type in the c programming
language. However 1.0 is designed to correspond to the highest voltage
the dac in your sound card can send to your amplifier. Any sample value
above 1.0 or below -1.0 will be clipped to those limits.
The output of a summing bus with subsequent processing will start
clipping before any individual signal actually reaches 1.0.
