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

seewave (version 1.2)

Time wave analysis and graphical representation

Description

seewave provides 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, cross correlation and autocorrelation, zero-crossing, dominant frequency, 2D and 3D spectrograms.
