From ce65c30264be9683dd3a59b35730d2f31e02d37f Mon Sep 17 00:00:00 2001 From: John Glover Date: Thu, 21 Oct 2010 13:39:28 +0100 Subject: Changed from floats to doubles in the C/C++ code, makes Python integration a bit easier. Fixed a bug that would cause SndObjSynthesis to crash if peak values were floats. --- examples/resynth.py | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 examples/resynth.py (limited to 'examples/resynth.py') diff --git a/examples/resynth.py b/examples/resynth.py new file mode 100644 index 0000000..ae4b6ec --- /dev/null +++ b/examples/resynth.py @@ -0,0 +1,39 @@ +# Copyright (c) 2009 John Glover, National University of Ireland, Maynooth +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
