Re: New/improved plug-ins for potential inclusion in Audacit

Even if I'm always cited as the "original" author of the "Vocoder" effect, it was never *my* idea to include the vocoder in the standard Audacity distribution, mainly because Audacity lacks nearly everything that's needed to work with the "Vocoder" in an at least semi-reasonable way. The main reason...

Re: frequency elimination/dampening using nyquist

The "quick & dirty" solution would be to type the frequency value with the keyboard into the small text window beside the slider. As far as I can see from the code, the plugin works with frequencies up to samplefrequency/2, the 10kHz is only an artificial limitation of the slider range. Just tested ...

Re: New/improved plug-ins for potential inclusion in Audacit

I guess that we could eventually end up lots of different vocoder effects. I still would like to have a "unified" vocoder effect, but I'm afraid that this is again a lot of work. There are still a lot of internal Nyquist details I still haven't fully understood. If I use e.g. a single Nyquist "osc"...

Re: New/improved plug-ins for potential inclusion in Audacit

I agree, the "Vocoder" is a fundamentally different effect than the "Easy Vocoder", even if both names sound very similar. The main internal difference and the main reason why combining both effects is not as easy as it sounds is that the "Vocoder" uses one single carrier for all vocoder bands, whil...

Re: New/improved plug-ins for potential inclusion in Audacit

If anybody wants to play with the "Easy Vocoder" effect: Download: http://www.audacity-forum.de/download/edgar/plugins/vocoder/easy-vocoder.ny - right-click -> save target as... The "Easy Vocoder" needs no special stereo audio tracks with "carrier" and "modulator" channels, it can be applied to an o...

Re: Sound envelop detector and auto-correlation

An audio track rectifier with Nyquist in Audacity_1.3.13-beta is dead easy. Select the [part of the] Audacity audio track you want to rectify, then open "Effect > Nyquist Prompt" and copy the following code into the "Nyquist Prompt" text field: (s-abs s) Then click "OK". A complete "analyze" plugin ...

Re: Not-well-formed (invalid token) errors with .aup files

I don't know what GEdit says but I know that Gedit is crap. GEdit can handle UTF-8 only and everything else is pretty much a mess. That's why I don't use it. Emacs says: http://www.audacity-forum.de/post/21648 - ISO-8859-1- [project name contains german umlauts] http://www.audacity-forum.de/post/216...

Re: Not-well-formed (invalid token) errors with .aup files

The bug has nothing to do with Unicode vs. non-Unicode builds, its always one and the same Audacity build that cannot read its own project files any more. It's correct that non-Unicode Audacity builds write ISO-8859 encoded .aup-files, what is strictly spoken wrong according to the XML specification...

Not-well-formed (invalid token) errors with .aup files

With Audacity_1.3.12 and 1.3.13 beta in the german Audacity support forum I have an increasing number of complaints that Audacity cannot read .aup project files that Audacity itself has written before without raising errors. The effect is that the complete project cannot be opened anymore. Examples ...
