Latency measurements

The importance of low and consistent latency in interactive music systems is well-established. So how do commonly used tools for creating digital musical instruments and other tangible interfaces perform in terms of latency from user action to sound output?

Metric Modulations Dataset

We present a dataset of annotations of tracks containing metric modulations.

A metric modulation is defined by a relatively abrupt change of metrical structure over time.
In order to capture this, for each track the annotations consist of:

  • Beat locations
  • Downbeat locations
  • Metric modulation locations (i.e. timestamps of the metrical structure change)
  • All metrical level pulse rates
