makeSpectrogram()

MatrixXd Spectrogram::makeSpectrogram ( Eigen::VectorXd signal, qint32 windowSize )

static

Calculates the spectrogram (tf-representation) of a given signal

Parameters

[in]	signal	input-signal to calculate spectrogram of.
[in]	windowSize	size of the window which is used (resolution in time an frequency is depending on it).

Returns

spectrogram-matrix (tf-representation of the input signal).
