Plugin for Isochronic Tone Modulation in Audacity

These are modified versions of the Isochronic Modulator Audacity plugin originally written by Steve Daulton.
(https://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Isochronic_modulator)

IsomodExtended.ny
Initial Modulation Frequency and Final Modulation Frequency increased to 150 to allow gamma frequencies.

IsomodInOut.ny
Allows separate Fade-in and Fade-out settings instead of just one time setting used for both in the original plugin.

IsomodEnvelope.ny
Allows traditional envelope settings (attack, decay, sustain, release)

The included audio sample is 4 sequenced samples that match the samples represented in the Audacity screenshot:

• 440Hz for 5 seconds.
• IsomodExtended for 5 seconds. Equal fade-in and fade-out times of the original plugin.
• IsomodInOut for 5 seconds. Different fade-in and fade-out times.
• IsomodEnvelope for 5 seconds. Attack/Decay/Sustain/Release envelope segments.

Blog post from Brian Slartsani's blog The Dynamic State and does a good job of describing how to use the original Isochronic Modulator plugin. (https://thedynamicstate.wordpress.com/2016/12/24/creating-isochronic-tones-with-audacity/)
