AIPL SpinCycle v2.1

Add big 24-bit Leslie / rotary speaker sound to your digital music and make it FAT! Building on years of research, and Leslie speaker analysis, AIPL SpinCycle is the best audio plug-in to digitally simulate a rotating speaker. If you closed your eyes and played an actual rotating / Leslie speaker, then played SpinCycle, we bet you couldn't tell the difference! We couldn't! It's that good (patent 6,873,708 and another patent-pending).

Add this sound to organ (e.g. Hammond organ), or to guitar and vocals to produce harmony or a unique flange, and hear the difference! AIPL SpinCycle simulates a mechanical rotary tremolo and vibrato system and is based on the Doppler-effect. There are thus no sonic tradeoffs, just great big rotary sound!

In addition to simulating the vibrato and tremolo modulation, SpinCycle simulates the tube pre-amp, as well as automatic speed controls (more below) and stereo-effects for an infinite number of microphone placements. SpinCycle has controls that automatically control the speed of the rotors. Try the AutoRhythm and AutoSpeed settings. To simulate the classic Leslie foot pedal, us the AutoRhythm setting. To create a totally new and cool "flange", mix a stereo track where both tracks are identical, except one is faded in or out, using AutoSpeed.

The 24-bit sound-processing algorithm is based upon a theoretical and experimental analysis of the frequency and amplitude modulation produced by a rotating speaker. The digital algorithm efficiently solves the actual equations produced by a rotating speaker. The algorithm is not a simple approximation as necessary with previous analog equipment. If you are concerned about required computational power, SpinCycle will run in real-time on any Pentium. If you want extremely accurate sound (labeled ProSound), you can select this option on SpinCycle for previewing and/or processing your audio.
