When there's a DC or lots of low frequencies, Speex cannot do a very good job. Jean-Marc -- Jean-Marc Valin <Jean-Marc.Valin@USherbrooke.ca> Universit? de Sherbrooke

How can I understand when I got a DC? I have an idea which is to look all the samples for min/max values and translate them but it looks way too much simple to work.
