export {seewave}

Export sound data

Description

Export sound data as a text file that can be read by a sound player like 'Goldwave'

Usage

export(wave, f = NULL, channel = 1, filename = NULL, header=TRUE, ...)

Arguments

wave

an R object.

f

sampling frequency of wave (in Hz). Does not need to be specified if embedded in wave.

channel

channel of the R object, by default left channel (1).

filename

name of the new file. (by default the name of wave).

header

either a logical or a character vector, if TRUE add a header to be read by Goldwave, if FALSE does not add any header, if a character vector add the character vector as a header.

other write.table parameters.

Details

Creates a new text file with a header describing the main features of the sound (wave). For instance, for a 2 s sound with a sampling frequency of 8000 Hz, the header will be: [ASCII 8000Hz, Channels: 1, Samples: 160000, Flags: 0]. This type of file can be read by sound players like Goldwave (http://www.goldwave.com/).
