/dsp/automute not working?

Spat
#1

I’m trying to use /dsp/automute 1 with spat5.hoa.binaural~ : it doesn’t seem to do anything.
(I would expect it to automatically do the same thing as /dsp/mute 1 , reducing CPU load)
setting /dsp/automute/attack to a low value (in seconds) doesn’t changes anything.

I’ve tried with other spat5.pan~ or spat~ : same behavior.

Is it supposed to work ?

Well, the “automute” does work, but it is indeed not implemented everywhere.
There are several reasons for that.

  1. For many objects, checking for “activity” in the incoming signals is actually more costly than the processing done by the object itself. Therefore automute would be counterproductive.
  2. Automute might be problematic with some stateful objects, because it takes time to “wake up” the object after a mute period.

So, automute is a feature that may be misused. Therefore, I sometimes decide to NOT implement it, just to prevent misusage.
That being said, I think it should work for spat5.spat~ (at least for some panning types).

Best,
T.

it seems to work fine with
spat5.spat~ @inputs 16 @internals 8 @outputs 2 @mc 1 @initwith “/panning/type nearfieldbinaural, /dsp/automute 1, /dsp/automute/attack 1”
but not with
spat5.hoa.binaural~ @order 3 @dimension 3D @mc 1 @initwith “/dsp/automute 1, /dsp/automute/attack 1”
