Main Section
So how should one think of the various main processing options in
relectro ? First of all they behave similar than their name-giving
counterparts, but with different audible results and usually not in the way
one would expect. Lets look at this sound sculpturing tools one by one:
The Compressor / Expander is doing exactly this compressing or
expanding of the dynamics, however, on a per-wave-cycle basis. It has no
threshold, like you might know it from a usual compressor, the relectro just
compresses audio at every level. The same applies for expansion, but you
know that by now, so lets stick with compression for this description, it
always applies for expansion as well.
It also has no attack or release parameters, simply because it treats every
wave cycle on its own, and as every wave-cycle has a certain audio level
there is no need of attack or release.
What remains is the compression ratio which can be adjusted with the
slider from no compression all the way up to 60 dB compression. This is an
tremendous rate, however, the logarithmic response of the slider allows you
to adjust it nicely.
Note: As each wave-cycle is processes individually, all kinds of sonic
artefacts will arise, particularly with high compression (this however is
almost no issue when expanding the dynamics).
Next is the Cut-Filter, which is similarly to a combined high-pass and low-
pass filter. This results in a kind of band-pass filter with a adjustable width
(range of frequencies which pass). When you move the high-pass higher as
the lowpass is, it turns from band-pass into band-reject, so that only wave
cycles outside of the selected frequency range will pass through.
