wav2flac {seewave}

R Documentation

wav-flac file conversion

Description

This function converts .wav files into .flac files and reversely

Usage

wav2flac(file, reverse = FALSE, overwrite = FALSE,
exename = NULL, path2exe = NULL)

Arguments

`file`	the .wav or .flac file to convert.
`reverse`	logical, if `TRUE` converts a .flac file into a .wav file.
`overwrite`	logical, if `TRUE` overwrites the file to convert.
`exename`	a character string specifying the name of the FLAC binary file. If `NULL`, the dedault name "flac" will be used for Linux OS and "flac.exe" for Windows OS.
`path2exe`	a character string giving the path to the FLAC binary file. If `NULL`, the dedault path "c:/Program Files/FLAC/" will be used for Windows OS.

Details

The function runs FLAC. FLAC has then to be installed first, if not the function will not work.

Value

A new file is created.

Note

FLAC must be installed to use this function but not to install the package seewave. Free Lossless Audio Codec (FLAC) is a file format by Josh Coalson for lossless audio data compression. FLAC reduces bandwidth and storage requirements without sacrificing the integrity of the audio source. Audio sources encoded to FLAC are typically reduced in size 40 to 50 percent.
