SPEC STRETCH: Stretch or compress intervals between frequencies across the spectrum, creating inharmonic sounds. WAVER: Oscillating inharmonic stretch. SPEC STRETCH The frequency gaps between partials are stretched (max stretch>1) or compressed (max stretch<1) above or below the dividing frequency freq split. The result is to turn harmonic into inharmonic sounds. The stretch factor exponent determines whether the stretching/compression is linear or exponential. The depth of the stretch effect can be varied. MODES 1. Above given freq: Stretch or compress above dividing frequency 2. Below given freq: Stretch/compress below dividing frequency PARAMETERS freq split The dividing frequency above (Mode 1) or below (Mode 2) which frequencies are stretched / compressed. Range: 5-22050 Hz
max stretch
Transposition
ratio of the topmost component (upward stretch): stretched
(values
>1) or compressed (values <1).For a downward
stretch, it
is (presumably) the transposition ratio of the lowest
component to be
stretched.
Range:
0.000454 to 2205 (=1/10 of full freq. range).
Soundshaper: 0.001-1-100
but these limits can be exceeded.

WAVER Variant of SPEC STRETCH. Stretching oscillates from original (harmonic) state to the maximum stretch factor (stretch) and back. Parameters are much the same as in Spec Stretch, though compression is not available. MODES 1. Standard: Linear stretching above the dividing frequency. 2. Exponential: Exponential stretching above the dividing frequency. PARAMETERS vib freq Oscillating frequency. Minimum value is determined by file length: longer sounds are permitted slower oscillations. Range: Min-172.26 Hz; Min: >1/File-length
stretch
Stretch factor: sets
the maximum spectral stretch (oscillation from harmonic to
stretch.).
High value
will
start oscillation at high frequency, even if bot
freq is low.

range). 1 is no
stretch ― rather pointless.
bot freq The
dividing
frequency above which frequencies are stretched. If set
high-ish, most
of the original will also be present.Range: 10-22050 Hz

NOTES Upwards stretch: if the dividing frequency is set higher than the source's lowest frequency, much of the original may be preserved. Equally if the frequencies above this are stretched too much, they will not be heard at all. WAVER: depending on the speed of vib freq, the original harmonic state may not be heard. As in all LFO modulations, when vib freq exceeds about 50Hz, it creates a steady frequency of its own.
