    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 and limited.
    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 quality.
    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 analog references.
    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.

    LinearPhase PEQ Orange

    DirectX/VST 10-band precise linear-phase parametric equalizer for mastering and re-mastering of complex mixes with unrivaled transparency and free of unwanted sound coloration and transient smearing

    The LinearPhase PEQ Orange 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 to our proprietary low-noise filter design in the time domain, the distortions (THD+N) are extremely low ensuring crystal clear, neutral, and uncolored sound.
    The LinearPhase PEQ Orange 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.

Algorithmix is proud to offer you a true remedy against difficult equalizing tasks, the LinearPhase PEQ Orange PlugIn, a linear-phase equalizer which can be handled exactly like its classic predecessors, but cannot be "heard".

    The LinearPhase PEQ Orange successfully copes with sonic problems that cannot be solved with any classical equalizer without side effects. 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 Orange works in the time domain. It sounds more analytical than its brother, the LinearPhase PEQ Red, and therefore is specially recommended for difficult mastering and re-mastering tasks on dense mixes. It performs flawlessly with up to 384 kHz sampling frequency and allows extended frequency setup up to 80 kHz, thus being ideally applicable for high-resolution DSD post-processing, including its ultrasonic region.
