Re: Why bother with lossy encoding?

Thankx I just started poking around in the effects. the Reverb is awesome; looks better than the one in GOM, and the only problem I have with the EQ is setting th Q if it can be done, some of the Draw images have a tendency to shelf rather than bell curve, unless there's something I'm missing. Drawing the EQ is pretty advanced stuff. I'll also look for things like channel strip (EQ, Compression, saturation and reverb) or maybe you can set things up so that you can automate one. I have the distinct impression there is much more to Audacity than most people know

".NY" files are "Nyquist Plug-ins" and are unique to Audacity.
