ContinuousWaveletTransform

ContinuousWaveletTransform[{x1, x2, ...}] gives the continuous wavelet transform of a list of values xi.

ContinuousWaveletTransform[data, wave] gives the continuous wavelet transform using the wavelet wave.

ContinuousWaveletTransform[data, wave, {noct, nvoc}] gives the continuous wavelet transform using noct octaves with nvoc voices per octave.

ContinuousWaveletTransform[sound, ...] gives the continuous wavelet transform of sampled sound.

Examples

Transform a signal:

signal = Table[Sin[2 Pi t] + Sin[4 Pi t], {t, 0, 10, 0.01}];
cwt = ContinuousWaveletTransform[signal];
WaveletScalogram[cwt]
