A novel software architecture for robust partial tone tracking and sound onset localization in audio signals is presented. Two spectral resolutions are evaluated in parallel, a broadband one for onset localization and a narrowband one for partial tone tracking. The fusion of the two, in conjunction with noise floor estimation and adaptive feedback cancellation, yields a robust and precise tool for audio signal analysis.
