Generating files with libsndfile


#1

I’m trying to generate sound files with the ruby wrapper around
libsndfile.[1]

I have no problem reading sound files as there are examples for this
in the documentation. But writing is another matter.

This script

require ‘audio’
require ‘audio/sndfile’
sf = Audio::Soundfile.new("/tmp/anewfile.wav")
silence = Audio::Sound.float(100)
sf.write_float(silence)

Will generate this error when run:

System error.
(eval):2:in `write_float’: Format check failed: 0 (RuntimeError)
