There is a mention of what the "big boys" are doing - well they're almost all using software based processors, Tue, 09 Feb 2010 19:54:40 GMT Gavin Stephens http://au.groups.yahoo.com/group/LPFM_Radio/message/6183 http://au.groups.yahoo.com/group/LPFM_Radio/message/6183 Most Optimods these days are all digital and have been for quite some time. They're not much different than a PC running software.

I know a lot of people bag the Behringer gear, but I've used a one of their companders for recording live music and found it pretty good, although a bit Tue, 09 Feb 2010 19:06:01 GMT Chris Diack - Classic Gold Radio Invercar http://au.groups.yahoo.com/group/LPFM_Radio/message/6181 http://au.groups.yahoo.com/group/LPFM_Radio/message/6181 Do you intend to use the Jesse's Behringer in your on air chain ?

Just thinking about this. Why do it digitally at all? Why not use an analog compressor/limiter?

The overshoot problem is actually due to poor prediction algorithms in the Tue, 09 Feb 2010 00:45:50 GMT Geoff Barkman http://au.groups.yahoo.com/group/LPFM_Radio/message/6174 http://au.groups.yahoo.com/group/LPFM_Radio/message/6174 Hi John I believe Jack has plug ins for doing stuff to Audio...

The Antex one (without MPX) just about max's out the CPU before MPX is even Mon, 08 Feb 2010 23:43:02 GMT Gavin Stephens http://au.groups.yahoo.com/group/LPFM_Radio/message/6171 http://au.groups.yahoo.com/group/LPFM_Radio/message/6171 If you have two 16 bit samples in a row, the D/A converter can "guess" what the orginal audio in between those samples was, and therefore make peaks sometimes Mon, 08 Feb 2010 17:20:45 GMT andy archer http://au.groups.yahoo.com/group/LPFM_Radio/message/6170 http://au.groups.yahoo.com/group/LPFM_Radio/message/6170 100% right Chris....thats the rub when using cheap imitation processing rather than a good orban optimod or other REAL method. Nothing works better than the
