Download Neural-Driven Multi-Band Processing for Automatic Equalization and Style Transfer We present a Neural-Driven Multi-Band Processor (NDMP), a differentiable audio processing framework that augments a static sixband Parametric Equalizer (PEQ) with per-band dynamic range
compression. We optimize this processor using neural inference
for two tasks: Automatic Equalization (AutoEQ), which estimates
tonal and dynamic corrections without a reference, and Production
Style Transfer (NDMP-ST), which adapts the processing of an input signal to match the tonal and dynamic characteristics of a reference. We train NDMP using a self-supervised strategy, where the
model learns to recover a clean signal from inputs degraded with
randomly sampled NDMP parameters and gain adjustments. This
setup eliminates the need for paired input–target data and enables
end-to-end training with audio-domain loss functions. In the inference, AutoEQ enhances previously unseen inputs in a blind setting, while NDMP-ST performs style transfer by predicting taskspecific processing parameters. We evaluate our approach on the
MUSDB18 dataset using both objective metrics (e.g., SI-SDR,
PESQ, STFT loss) and a listening test.
Our results show that
NDMP consistently outperforms traditional PEQ and a PEQ+DRC
(single-band) baseline, offering a robust neural framework for audio enhancement that combines learned spectral and dynamic control.
