Best practices for audio circuit simulation

Hi all, I've been modeling a lot of guitar effects lately (please check my public circuits list) and tend to just run a time-domain with a 1Hz sine 100mV input to simulate the guitar. For boost circuits this seems logical as I can evaluate the output signal strength, and for clipping I can see the distorted waveform...

But I was wondering what others are doing?

Hey geedeebee, cool stuff. I looked at some of your circuits and it seems that you are using a 1kHz sine in general. That seems reasonable, however you may want to consider using the frequency domain analysis tools (if you haven't already).

You might also like to consider using a square wave input signal in addition to sinewave testing.

Using a square wave can, in a single time domain simulation run, tell you a lot about the transient and - if you understand how to interpret the waveforms - the frequency response of a circuit.

This site gives a bit of insight into the sort of information you can get from this type of testing:

I'm sure Google can find you more.
