From 526277c97c8c1e77252d3c67186914789ba55c33 Mon Sep 17 00:00:00 2001 From: Arun Raghavan Date: Tue, 7 Sep 2010 13:43:58 +0530 Subject: echo-cancel: Add alternative echo-cancellation implementation This adds Andre Adrian's AEC implementation from his intercom project (http://andreadrian.de/intercom/) as an alternative to the speex echo cancellation routines. Since the implementation was in C++ and not in the form of a library, I have converted the code to C and made a local copy of the implementation. The implementation actually works on floating point data, so we can tweak it to work with both integer and floating point samples (currently we just use S16LE). --- LICENSE | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'LICENSE') diff --git a/LICENSE b/LICENSE index 612c2341..3a82749e 100644 --- a/LICENSE +++ b/LICENSE @@ -10,4 +10,8 @@ LGPL licensed and the server part ('libpulsecore') as being GPL licensed.
