AutoEQ optimizer for Poweramp (64-band parametric, biquad simulation)

[Euvony]

I developed a high-resolution AutoEQ optimizer designed specifically for Poweramp parametric EQ.

Unlike magnitude-only fitting approaches, this tool simulates real parametric biquad filters and jointly optimizes gain, center frequency, and Q using robust loss functions and perceptual weighting.

Main goals:
• improve realism of EQ correction
• allow fine control for narrow IEM resonances
• maintain smoother transitions and more natural tonal balance

Current features:
• multi-resolution optimization
• psychoacoustic weighting
• up to 64 parametric filters
• preset export ready for Poweramp
• GUI workflow (measurement → target → preset)

Tested on several IEM measurements with reasonably consistent results.

GitHub - DAPAAADF/AutoEQ-Parametric-64band-for-Poweramp: Psychoacoustic-aware 64-band parametric EQ optimizer for Poweramp. Takes stereo IEM measurements and a target curve, outputs a ready-to-use PEQ preset.

I would appreciate technical feedback regarding:
• risk of overfitting with high filter counts
• phase and ringing behaviour
• optimization strategy improvements
