FFT based wav player that allows separate control over time and pitch.
This simple method of timestretching uses the phase difference between
blocks to reproduce accurate pitch at the expense of creating diffusion
due to phase being misaligned on stretched/compressed blocks.
The result sounds noisy with minor adjustments but reproduces accurate
pitch even with extreme modification (e.g. 1024 times timestretching or
much more is possible). The sample may be scanned as if it were "frozen".
With the inclusion of frequency shifting, Sifft is well suited for
experimental sounds and percussion resynthesis.
Features include:
loads 8, 16, or 24 bit wavs.
3 waveform interpolation modes: none (floor), linear, and cubic.
emulated downsampling to 1 bit.
a bunch of filter modes (low, band, high, cut, peak in Moog, Simper svf
or RBJ biquad).
curveable envelopes and modulating LFO contours.
Sifft includes the core process as a SEM module for SynthEdit users and
c++ source for the process with notes. A selection of other SEMs are
included, e.g. envelopes and filters.
