Offers low-latency, high-resolution spectral analysis by uniquely combining known phase vocoder techniques, yielding 'incredibly satisfying' results like super-resolution spectrograms and re-synthesis experiments.
Resonate advances real-time audio processing through a novel combination of established phase vocoder techniques, yielding 'low-latency, high-resolution spectral analysis.' This innovation addresses critical performance and fidelity requirements in fields like music production, audio engineering, and scientific research. The ability to efficiently extract frequency components and generate 'super-resolution spectrograms' offers significant value for detailed audio manipulation and analysis. While the underlying techniques are not new, their synergistic application represents a valuable intellectual property. This project demonstrates how re-contextualizing existing algorithms can unlock new capabilities, impacting industries reliant on precise audio data interpretation and synthesis. The academic recognition underscores its technical merit and potential for broader adoption.
Last April I shared about my Resonate project here (https://news.ycombinator.com/item?id=43694157)A lot has happened since: the work I presented in much more detail at last June's International Computer Music Conference (ICMC) got best paper award. I also gave a talk at the Audio Developer Conference in Bristol last November, the video is on YouTube).This year's work, which I recently presented at this year's ICMC, starts with known techniques from the phase vocoder literature to build self-tuning filter banks that extract very efficiently the frequency components that are actually present in the input signal. Overview on the project website, more details in the papers, including applications to super-resolution spectrograms and re-synthesis experiments.As many people have pointed out, none of the techniques I have used are new (some of them even have different names across different fields), but I haven't seen them applied together in this way, and to me the results are incredibly satisfying and sometimes look magical. See for example this demo: https://youtu.be/LasdoIJJkw8Of course the best way to experience in person is through the free demo app: https://alexandrefrancois.org/OscillatorsLooking forward to feedback from the community!
