The easiest solution would be to modify the tremolo code so that the pulses fade in/out.

I've modified the Variable Tremolo effect so that the pulses are adjustable.
To save space in the interface and simplify the code I have taken out the other waveform options.

The "Pulse Width" control allows you to set how long each pulse will be. Higher values will make the sound "on" for longer. Lower values for shorter pulses. At 50% the sound will be on for 50% of the time.

The "Fade Time" control may be increased for a more gradual fade in/out of the pulses. At 0% there will be no fade. At 100% the fade in/out times will be half of the pulse width.


If you want to change the default values, open the isomod.ny file in a text editor and change the numbers shown below, then save.

;control pw "Pulse Width [50%=Square]" real "%" 40 0 100
;control ft "Fade Time" real "%" 15 0 100
;control startf "Initial Modulation Frequency" real "Hz" 7 1 20
;control endf "Final Modulation Frequency" real "Hz" 2 1 20
;control starta "Initial Modulation Depth" int "%" 100 0 100
;control enda "Final Modulation Depth" int "%" 100 0 100

I've renamed this plug-in "IsoMod..." (Isochronic Modulator).

This version is also compatible with Audacity 1.2.6

Steve, you are awesome! This will be a time-saver indeed (and will help overcome numerous of Audacities editing flaws/imperfections). I've been doing this the hard way till now, which doesn't support isochronic ramping anyway... something I really wanted. But luckily you've saved the day (after I decided to Google 'Audacity isochronic plugin') ...and what damned good timing too! I had just thought about learning how to make plugins just to do this, but that's not something I really have time for anyway.

So from the bottom of my heart, thanks a million! I registered just to say that, too... ;)

Cheers!

Sorry...

I'm a bit of a novice. I downloaded the attachment but have no idea how to open it within Audacity so that I can use the plug-in.

Mind giving me a quick tutorial?

Plug-In Installation

To install new plug-ins, place them in the Plug-Ins folder inside the Audacity installation folder. On Windows computers, this is usually under "Program Files". On Mac OS X, it is usually under "Applications". Restart Audacity, then the Plug-ins will appear underneath the divider in the "Effect", "Generate" or "Analyze" menus.

Does this plugin work for the latest beta version for windows 7? I downloaded the plugin it and placed it into the plugins folder but I do not see it show up in any menu.

Thanks.

Did you restart Audacity?
