Re: Frequency Shifter MP3's

Glad you liked the sounds. I will try to find some more acoustic-type
sounds to process if I get the chance. Argh, too many things to do and
not enough time! :-)

shifter sounds a bit like a ring modulator when it gets really high, but
otherwise, it's
not like any effect I've heard before. If it was kept to smaller ranges,
it could almost
pass as varispeeded tape, minus the speed changes. I'd be curious to
hear what it sounds
like on acoustic sounds (voice, piano, guitar, etc). The phasing effect
is cool - it sounds
more like flanging than what you'd get with a conventional phaser, but
not as metallic as
flanging and without the delay. There's almost a "barberbole", Shepard
tone thing going on
in these samples. Very cool.
