The same tuning method is used for the NNLS Chroma and Chordino plugins. + +### Parameter ### + +* spectral roll on (0.00 -- 0.05; default: 0.0): consider the cumulative energy spectrum (from low to high frequencies). All bins below the first bin whose cumulative energy exceeds [spectral roll on] x [total energy] will be set to 0. A value of 0 means that no bins will be changed. + +### Outputs ### + +* Tuning: returns a single label at time 0 seconds containing the tuning information in Hz. +* Local Tuning: returns a tuning estimate at every analysis frame, an average of the (recent) previous frame-wise tuning estimates. + ## References and Credits ## +Mauch, Matthias and Dixon, Simon: [*Approximate Note Transcription for the Improved Identification of Difficult Chords*](http://schall-und-mauch.de/artificialmusicality/?p=89), Proceedings of the 11th International Society for Music Information Retrieval Conference (ISMIR 2010), 2010. -
