Time Compression - ESI ESI2000 Operation Manual

Tip: A standard analog parametric
equalizer may be useful in order to locate the
frequencies which need EQ. The digital EQ
can then be used to actually filter the sample
with ultra-low noise and phase linear
response.
Time Compression Ratio:
200% = Double Length
50% = Half Length
Tip: If you are not happy with the results
of Time Compression, simply Undo, then
choose another algorithm.

6. If you are not satisfied with the resulting EQ or want to compare
before and after, proceed to Digital Processing, 9. Undo.

4. Time Compression

This function allows you to change the length of a sample without
changing the pitch. This is a useful function 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%.
1. Activate Digital Processing module.
2. Select Digital Tools II (8), Time Compression (4). The display
will show the current time compression ratio and signal type.

3. Select the desired time compression (or expansion) ratio. The
lower line of the display changes to show the resulting length of the
compressed or expanded sample.
4. Select the general type of sample to be processed.
Refer to the chart on the following page for a list and brief descrip-
tion of the sample types.
5. If you are not satisfied with the resulting Time Compression or
want to compare before and after, proceed to Digital Processing,
