Resonate Resonate is a low latency, low memory footprint, and low computational cost algorithm to evaluate perceptually relevant spectral information from audio (and other) signals.

I presented my paper “Real-Time, Low-Latency, High Resolution Audio Spectral Analysis: Phase Matters” at the 2026 International Computer Music Conference (ICMC) on May 14 2026. This is building on the work that received the Best Paper Award at last year’s ICMC, where I introduced the Resonate model. Watch a demo video on YouTube!

I gave a talk titled “Real-time, low latency and high temporal resolution spectrograms” on the implementation of Resonate and Resonate-based spectrograms at the Audio Developer Conference (ADC25), Bristol, November 10-12. Watch on YouTube!

I gave a late breaking demonstration of Resonate-based real-time, low latency audio features computation at the First AES International Conference on Artificial Intelligence and Machine Learning for Audio (AIMLA 2025), London, Sept. 8-10, 2025.

“Resonate: Efficient Low Latency Spectral Analysis of Audio Signals” received the Best Paper Award at the 50th Anniversary of the International Computer Music Conference 2025, which took place June 8-14 in Boston, MA, USA.
