ESI-32 Operation Manual
This submodule contains eight more digital functions. These are ex-
tremely useful utilities for manipulating samples. Following is a short
description of each function.
0. Sample Rate Convert: Converts the sample to any sample rate
between 7000 Hz and 50000 Hz.
1. Digital Tuning: Digitally re-tunes a sample within a range of ±1
octave.
2. Compressor: The compressor dynamically changes the gain of the
sample based on the amplitude envelope of the sample. This is a
non-realtime implementation of a full featured dynamic range
compressor.
3. Parametric Equalizer: This is a digital (non real-time)
implementation of a one band parametric EQ, with +12 dB boost or
-48 dB of cut and completely variable frequency and bandwidth
controls.
4. Time Compression: This function changes the length of a sample
without changing the pitch. This can be very useful for fitting
samples to the beat of a song or fitting dialog into a spot. Samples
can be compressed or expanded in length from 50% to 200%.
5. Pitch Change: This function changes the pitch of a sample without
changing the time relationships between events. The maximum
amount of pitch change is ±1200 cents (± one octave).
6. Transform Multiplication: This function merges two sounds
together in a unique way which can create many strange and
beautiful sonic textures. Frequencies common to the original sounds
are accentuated while uncommon frequencies are discarded.
7. Doppler/Pan: This unique function allows you to dramatically move
a sound from front to back and side to side in a 2-D space. Several
pre-computed paths as well as 10 user-definable paths are available.
