DirectX/VST 10-band precise linear-phase parametric equalizer featuring
unique shelving filters for mastering of complex mixes without changing
their sonic character
Every mastering engineer knows that equalization of final complex
mixes or orchestral recordings with stereo microphones is very critical
Any correction of a single instrument or vocal part influences other
instruments and can negatively change their sound characteristics.
This is because all classic equalizers change the phase of the fundamentals
and harmonics and the phase shift is frequency dependent.
The LinearPhase PEQ Red does not shift the phase. It only boosts or
cuts the amplitude in a given frequency range. Consequently, you can
apply much more boost without changing the sound character of your recording.
Due our proprietary low-noise filter design in the frequency domain,
the distortions (THD+N) are extremely low, ensuring crystal clear sound
The LinearPhase PEQ Red DirectX/VST PlugIn is unique in the
world of audio components. Almost all parametric equalizers being
used are implemented with filters that accomplish phase shift, e.g.:
the original signal is remixed with its phase-shifted version. Because
the amount of the phase shift is frequency dependent some cancellation
or amplification at certain desired frequencies takes place. It
works, but with a major disadvantage--the different signal components
are spread all over time, so that the time relationship between
harmonics in the processed signal is heavily affected. The result
is that a nice sharp bass drum becomes slurred and muddy, and vocal
tracks become strident or brittle. Algorithmix is proud to offer
you a true remedy against difficult equalizing tasks--the LinearPhase
PEQ Red PlugIn, a linear-phase equalizer which can be handled
exactly like its classic predecessors, but cannot be "heard".
Experts say that most of digital equalizers do not sound like their
analog predecessors, especially when working with low sampling frequencies:
44.1 or 48kHz. Spectrum modifications in the high-frequency region
sound as improperly balanced. The reason is so called frequency
warping which makes the bells asymmetric and high shelving and high-cut
filters much steeper as theoretically set up. To make the LinearPhase
PEQ Red analog sounding, special corrections have been applied
to the original digital filters making them look exactly like their
The LinearPhase PEQ Red features the Continuous Slope
Filter™ technology, proprietary to Algorithmix and the only
one of its kind, worldwide. Unusual flexible shelving and cut filters
allow adjustment of any slope in the range from 0 to 24dB/octave.
The LinearPhase PEQ Red better preserves the time relationships
of harmonics in the original waveform. This translates to smoother
top end, sweeter and bigger midrange, and a clearer more distinct
bottom end as compared with phase-shift EQ. The resultant sound
seems less processed, more like it occurred naturally in the air
in front of the microphone. The mixes become clear and transparent,
the instruments more defined and "realistic". You can boost lower
frequency regions by even 10dB without mud or slush and with no
loss of transients at all. You can remove the sibilance from a vocal
with a sharp notch without affecting the whole mix like occurs when
using analog or IIR-based digital EQ.
The LinearPhase PEQ Red
works in the frequency domain. It sounds
a bit softer than his brother, LinearPhase PEQ Orange
. It perfectly
performs with up to 384kHz and allows extended frequency setup up to
80kHz. These features make it perfectly applicable for high-resolution
DSD post-processing, inclusive the ultrasonic region.
