Transform Multiply - ESI ESI2000 Operation Manual

Tip: Transform Multiplication can take
quite a bit of time with longer samples.
Begin your experiments with short samples
or even sample attacks as these will give
good initial results.
Transform Multiplication Ideas:
Try using the same sound for both
samples.
Splicing silence to the beginnings or
ends of short samples can change the
spectral characteristics of the result.
Using speech as one of the sources, it is
possible to "speak from within" violins,
bassoons, cymbals, etc.
!
Note Transform Multiplication needs extra
memory to perform its thousands of
calculations. If you get a memory error, load
just the two samples into the ESI and try
again.

ESI Operation Manual

6. Transform Multiply

This unique function merges two sounds together in a way that
accentuates frequencies common to both sounds while discarding
uncommon frequencies. Because of this characteristic, Transform Multi-
plication tends to work best with sounds that are harmonically rich.
Using this function is easy. Just pick two sounds and multiply! Although
you have to wait to hear the results, Transform Multiplication can
produce many strange and beautiful textures unattainable by any other
means. The length of the resulting sample will be equal to that of the
current sample.
1. Activate Digital Processing module.
2. Select submodule Select Sample (0).
3. Select the first source sample to be multiplied, then press Enter.
4. Select Digital Tools II (8), Transform Multiplication (6). The
display shows:

Select Second Sample
5. Select the second sample to be multiplied using the INC/DEC
buttons, the Data Entry Control or the keypad. The third line of
the display shows the characteristics of the second sample (L, R, or
L/R), the length and the sample rate.
6. Press ENTER to select the second sample. The display shows the
time required to process the samples.

Will take 26 mins..
7. Press Yes to start the computation or No to return to the Module
Identifier.

tion or want to compare before and after, proceed to Digital
Processing, Undo (9).
