Rectifier with Optional Modulation Description

A rectifier which applies a bias to the result, so that the plug-in can be re-applied with further added overtone harmonics with each application. Modulation types: constant, fade-in, fade-out, LFO. This is a rectifier that takes a signal (such as a sinewave or guitar track) that goes above and below the zero line, and either returns only the positive portion of the signal ("half rectification"), or it also returns the negative portion of the signal which has been made positive ("full rectification"). The result of such rectification is added higher frequency harmonics not in the original signal. Normally, rectification makes the entire signal positive, so re-applying a rectifier adds no further higher frequency harmonics. However, this plug-in takes an audio signal, applies half or full rectification, then converts the all-positive result into another signal which crosses the zero line. this means the plug-in can be re-applied to the result, adding additional high-frequency harmonics with each application. this plug-in also has four options for modulating the resulting rectified signal and mixing it back with the original signal. For instance, the default settings have the original selected signal in Audacity fade out while the rectified signal fades in. Variables: 1. Rectification type - half or full rectification. 2. Modulation type - up (rectified signal fades in), down (rectified signal fades out), constant (same level over time), LFO (low frequency oscillator, a sine wave which rises and falls below 20 cycles per second, so the non-rectified signal level rises and falls while the rectified signal falls and rises). 3. LFO frequency - frequency of the LFO signal, when LFO modulation is chosen. 4. Rectified volume - maximum volume of the rectified signal, in percent. Many guitarists use rectifiers as part of their 'effects suite'.the noisier the original guitar signal (from fuzz boxes, distortion pedals, etc.), the noisier will be the result from this plug-in. Works on mono and stereo audio. Requirements: Audacity
