AmpliDude Description Coyote AmpliDude is a DirectX plugin that implements high-quality amplitude modulation effects. Advanced audio processing algorithms produce a very clean output, free of artifacts. Some of the unique features of the Coyote AmpliDude are: Sine, triangle-wave and rectangle-wave low-frequency oscillator (LFO) Duty-cycle control for the rectangle-wave LFO option Randomized option for the LFO, for a more natural, less mechanical sound Built-in filters to allow amplitude modulation of specific ranges of frequencies Tap-tempo button for easily matching the tremolo rate to the beat of the song Handles professional audio formats, including 16-bit, 24-bit and floating-point, at up to 192 KHz sampling rate Supports presets Clipping indicator Coyote AmpliDude should be compatible with any audio application that accepts DirectX plugins. It has been tested with several of the more popular applications. Have a look at a screen shot: Tremolo By setting the LFO Type to Sine, a tremolo effect similar to that found in vintage amps and stomp-pedals is achieved. The LFO Rate, and Depth can be adjusted to obtain a wide variation in the effect, from a gentle oscillation, up to a rapid pulsation. Auto-panning Setting the Stereo button to Invert results in the left and right channels of a stereo signal being increased and decreased in amplitude in opposition to each other, which causes the sound to seem to sweep from left to right and back. Using the filter to control the range of frequencies which is swept can result in some subtle or wild effects, not available in any other plugin we know of. Stuttering Setting the LFO Type button to Rectangle results the amplitude suddenly switching between a high value and a low value. If you set the depth high enough, the audio will actually cut out periodically. Use the Duty Cycle slider to control the ratio between the "on" and "off" times. Again, the Filter control can produce some really unique sounds!
