Give tracks presence without flattening the source. Add air, articulation, and density through a tuned parallel path. AE975 is an AUv3 audio effect for subtle polish, forward detail, and playable control. AE975 keeps the dry signal as the foundation, listens to a Focus-controlled sidechain, generates source-derived harmonic texture, and blends the result back in parallel. The goal is mix-ready lift without treating brightness like a simple EQ boost. Sound-shaping controls: - Focus sets the responsive region from 600 Hz to 6 kHz, with 3 kHz at center. - Enhance controls the parallel return depth. - Texture changes harmonic color and complexity. - Saturation adds intensity inside the enhancement generator, not as a full-band clipper. - Density moves from clean transient sparkle to smoother sustained glow. - Mix, Output, and Bypass make level-matched comparison simple. Built for DAW workflows: - Use AE975 as an audio effect in compatible AUv3 hosts. - Open the standalone companion host app to audition the processor with generated test audio, or compatible hardware I/O. - Browse 92 categorized factory presets for mastering, mixing, buses, vocals, guitars, bass, drums, synths, strings, brass, woodwinds, and sound design. - Save user presets locally and mirror them with iCloud preset sync. - Map hardware controllers with MIDI Learn, direct CC assignment, reset-to-default controls, and feedback broadcast support. Use it when a vocal needs to read forward, drums need more snap, guitars need pick detail, synths need shine, strings need rosin, buses need polish, or a master needs a controlled final lift.
