⚠️There's a newer version (2.2.3) of this package.Take me there.

seewave (version 2.1.5)

Sound Analysis and Synthesis

Description

Functions for analysing, manipulating, displaying, editing and synthesizing time waves (particularly sound). This package processes time analysis (oscillograms and envelopes), spectral content, resonance quality factor, entropy, cross correlation and autocorrelation, zero-crossing, dominant frequency, analytic signal, frequency coherence, 2D and 3D spectrograms and many other analyses.
