Talk:Effect Menu

Here's some old text from the main page.

Does our compressor make "soft sounds louder"? Only if you normalize? - Gale Bill:  Yes, only if you "make up gain for 0 dB after compressing".

ToDo Move and merge anything useful in the old Noise Removal text (greyed out in the detailed text) into Noise Removal. Bill: done

Image included with Fade Out effect description. Do we want this image here? It is NOT showing the use of the envelope tool as implied by the preceding text. I don't think we need images for these simple fade effects, and I don't think they need their own pages. - Bill

Leveller - is the description appropriate?

Nyquist prompt - is the description appropriate?

Does Phaser need its own page?

VST Effects These instructions no longer apply, right?
 * You will also need to download and unzip the [|VST Enabler] To do: broken link to the same directory.
 * The next time you launch Audacity, any plug-ins you added will appear in the Effect menu.

Vocoder - I believe that this is a phase vocoder http://en.wikipedia.org/wiki/Phase_vocoder. I've played with it a bit but really have no idea how to describe it. - Bill I think that this short description is a good one because, is that this effect make : robotize voice. - Olivier

Bill: I propose that we lose this section. (from this page) JC: I second that. Parking it here for now so that if anyone wants to mine it for a super-dooper 'features of audacity' (not needed for 2.0) page they can.
