Compute Arbitrary Local Measurements

AudioLocalMeasurements can be used to compute several predefined properties on amplitude or spectral components of audio frames. Additionally, AudioBlockMap can be used to compute arbitrary properties and measurements on audio frames.

Compute the "Novelty", "HighFrequencyContent" and "SpectralCentroid" of a signal, computed on short-time Fourier data.

Compute arbitrary functions on audio frames using AudioBlockMap. Visualize the evolution of RMS amplitude in decibels over time in a collection of signals.

Define a color function to visualize the dB RMS amplitude.

Compute the resulting colors.

Display the computed colors of the first recording.

Display the computed colors from all recordings.
