LeakyIntegration: Leaky Integration

In m-vidal/pv01: An open source auditory toolbox for perception-based music analysis.

Description

Calculates leaky integration with specified half decay time.

Usage

LeakyIntegration(inSignal, inSampleFreq, inHalfDecayTime, inEnlargement)

Arguments

inSignal	input signal (multi-dimensional), each row representing a channel leaky integration is performed for each channel.
inSampleFreq	sample frequency of inSignal (in Hz).
inHalfDecayTime	time (in s) at which an impulse would be reduced to half its value. If empty or not specified, 0.1 is used by default.
inEnlargement	time (in s) to enlarge the input signal. If -1, 2*inHalfDecayTime is used. If empty or not specified, 0 is used by default

Details

Sample frequency of outLeakyIntegration is the same as inSampleFreq.

Value

An object of matrix class representing the leaky integration of the input signal.

Examples

s <- c(SchumannKurioseGeschichte)
ANIs <- CalcANI(s, 22050)
LIs <- LeakyIntegration (ANIs$AuditoryNerveImage, ANIs$ANIFreq, 0.1, -1)
