NAME

Audio::Extract::PCM::Backend::SoX - sox backend for audio extraction

METHODS

pcm_back

See "pcm" in Audio::Extract::PCM::Backend.

SYNOPSIS

Note that this backend does not support read, i.e. it only supports the pcm method, which will read all pcm data at once.

SUBROUTINES

get_sox_version

This will return the SoX version as a version object. The result will be cached, i.e. if you install a new sox, this module will not recognize it until it is reloaded or the application using it is restarted.

If no sox program is in the path or sox -h outputs strange things, undef will be returned. In the latter case, a warning will be issued.

Currently, the only internal use is to find out whether SoX is above version 13.0.0, because they renamed the "-b"/"-w"/"-l"/"-d" flags to "-1"/"-2"/"-4"/"-8" by then. Note that the old flags were still recognized (though deprecated) until SoX 14.1.0.

used_versions

Abstract interface to "get_sox_version".
