Can you add a float-less version for Teensys without FPU?

Hi Mark,

Just having a playing around with the dynamics effects - the compressor is very nice indeed but I have an issue:

When changing any of the compression parameters live, the sound mutes then fades back in fairly quickly. Is this intended? I have reviewed the library and can't find the exact place in the code that causes this. Is this intentional?

Any help would be great, thanks again!

Just a qestion, have you tested that your log and exp implementations are really faster than the fpu?

The powf expression may return NAN (Not A Number) if the audio level in is low from a source it seems. Then the compressor will not give audio data out and appears "dead" ...

Here:

To check if a NAN_ https://stackoverflow.com/questions/570669/checking-if-a-double-or-float-is-nan-in-c/570694

I added this "hacky" fix:

if (compdb != compdb) compdb = 0.0f; // trick to detect NAN .. Became a bit overmodulated with compdb to 1 so I set it to 0

I am not sure if it is a good idea to set it to zero however. At least this fixed the NAN issue.
