Volume level

[Bruce Davidson]

Hi, I'm looking at pyo to build a simple guitar amp. Whenever I process the signal with an effect, such as Phasor or Chorus, the volume is reduced. I feel like I'm missing something - how do I maintain the volume level, or is there a way to set an arbitrary base volume?

Can you share some code?

Hi Bruce,

> Hi, I'm looking at pyo to build a simple guitar amp. Whenever I process the signal with an effect, such as Phasor or Chorus, the volume is reduced. I feel like I'm missing something - how do I maintain the volume level, or is there a way to set an arbitrary base volume?

For what it's worth, I wrote a little blog post about guitar effects here: https://www.matthieuamiguet.ch/blog/diy-guitar-effects-python

In my experience, effects like chorus don't significantly change the output volume. Maybe you're doing something wrong?

Now, if you need more volume, every PyoObject has a mul attribute that allow to change its output volume. So for instance

c = Chorus(i, mul=1.5)

would boost the chorus output.

Hope this helps,

Matthieu

Hi,

I'd just put a Compress object at the end of the fx chain, and pump up the volume beforehand as needed...
