Real Time Beat Tracking using Novelty Curve

novelty curve. Section IV explains how the beat is aligned with respect to time and how they are subject to change as time progresses. Section V contains details of how the algorithm was implemented on an embedded device. II. NOVELTY CURVE Novelty curve is a mid level, subsampled representation of the the audio input. An audio novelty curve for ...

The overall novelty value is then computed as a weighted sum that can be configured using ‘weightCurve’ parameter. The resulting novelty curve can be used for beat tracking and onset detection (see BpmHistogram and Onsets). Notes: Recommended frame/hop size for spectrum computation is 2048/1024 samples (44.1 kHz sampling rate) [2].

This algorithm computes the "novelty curve" (Grosche & Müller, 2009) onset detection function. The algorithm expects as an input a frame-wise sequence of frequency-bands energies or spectrum magnitudes as originally proposed in [1] (see FrequencyBands and Spectrum algorithms). Novelty in each band (or frequency bin) is computed as a derivative ...

audio recordings. In this scenario, a first challenge is to locate note onset ... The magnitude encodes how well the novelty curve resonates with a sinusoidal kernel of a specific tempo The phase optimally aligns the sinusoidal kernel with the peaks of the novelty curve.

Novelty curve: Given an audio recording, we first derive a novelty curve. The peaks of this curve indicate note onset candidates. The peaks of this curve indicate note onset candidates. The variant provided by the Tempogram Toolbox is capable of capturing even soft note onsets, as typically occuring for string instruments.
