Audacity Forum

By the way, does Audacity use floating point internally or fixed point? In other words do I need to worry about clipping at every step or can it be left until the end and tamed with a look-ahead limiter? I know the Envelope tool shows values greater than 1.0, but that could just be the graphical rep...

That sounds like what I'm intending, with an extra control for the angle per pass. I removed the normalizing for testing purposes to compare like with like without significantly increased volume making the louder version sound better. With a decay of over 10 dB per pass, there's a chance of about a ...

Thanks, Robert, that helps a great deal. It's a bit like room modelling but with single echos decaying and separated by 25-50 ms or so, so that I avoid comb filtering of audible frequencies (which I'd get mildly with shorter delay) and avoid distinct echoes (which I'd get with a longer delay outside...

Thanks, Steve, Your replies are certainly helping me understand each aspect. I think those links and your description will help me understand what's going on. I was able to remove the normalize function from the delay_flip plugin and replace it with a scale factor (default 1.0) and change the defaul...

I have just found the following plugin in the archives, which is very close to the special case of 90 degrees I'm hoping to achieve. The main difference is that it forces Peak Normalization (though I guess I can edit). http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Delay_with_Stereo_Flip ...

Audacity 2.0.3, Win 7 32-bit for now (occasionally use on MacOSX and Linux) Hi, I had an idea, and was going to try implementing it using stereo cross-channel convolution in foobar2000 foo_dsp_stereoconv, but discovered that its 1024-point FFT limits the delay I can apply when convolving. Nyquist so...
