P440 Sweet Spot Mastering Equalizer audio plugin. You have very likely heard words similar to the following uttered many times about mastering: "it makes the music come to life" or "it is the final polish that transitions into something breathtaking" or "It is like. magic!".
The wizardry lies in the hands of the practitioner of course, but surely, as all wizards wield an unassuming yet infinitely powerful device that is a conduit between their mystical knowledge and the physical world, so does the mastering engineer. To the wizard, it is the magic wand and to the mastering engineer, it is the equalizer.
Forget everything you have been taught about "High Passing" frequencies below 30Hz, and welcome to Sweet Tremor boosting infrasonic frequencies! Attenuate frequencies and you end up with a punchier and open sound! Boost frequencies and end up with sweet cotton candy all over your ears! Scream in horror when you check in Plugin Doctor the low shelf at 200 Hz or the high shelf at 2 kHz with a "stairway to heaven" graph, but then melt in your chair when you listen to it- like candy on a hot summer day. Nothing makes sense .visually but your ears tell you otherwise.
P440 Sweet Spot EQ will let you rethink what an audio equalizer can do. P440. your mystical magic wand.
