SpaceTheremin version 1.01 has a smoother sound
without the overdriven signal distortion. The clean
sound may be more desirable for some uses.
Unlike a standard analog Theremin,
which typically has a sinewave oscillator and some
basic vibrato, SpaceTheremin lets you choose from
six different oscillator types (sine, square,
triangle, sinc, saw, and pulse). The same waveforms
can also be used for vibrato and modulation. It uses
OpenAL for sound generation.
Use of the vibrato can result in
some incredibly freaky and bizarre sounds. Set the
vibrato depth (in percent) and adjust the vibrato
frequency via the slider to hear the effects. A
vibrato depth of 50% and a triangle waveform gives
an interesting sound, for example.
Although the vibrato frequency
ranges from 0.1 to 12.0 Hz in 0.1 Hz increments,
checking the "modulation" box changes the range
maximum to 8000. Moving this slider into the audible
frequency range (20Hz and up) allows you to get
strange two-oscillator frequency modulation sounds.
