resamp: Resample a time wave

In seewave: Sound Analysis and Synthesis

Resample a time wave

Description

This function resamples (down- or over-samples) a time wave. This corresponds to a sampling frequency change.

Usage

resamp(wave, f, g, channel = 1, output="matrix")

Arguments

wave	an R object.
f	sampling frequency of wave (in Hz). Does not need to be specified if embedded in wave.
g	new sampling frequency of wave (in Hz).
channel	channel of the R object, by default left channel (1).
output	character string, the class of the object to return, either "matrix", "Wave", "Sample", "audioSample" or "ts".

Value

If plot is FALSE, a new wave is returned. The class of the returned object is set with the argument output.

Note

Resampling might change frequency properties of the time wave.
