I think the video world calls it sweetening which is what audio people refer to as mastering. So the effects for broadcast aren't echo or distortion. They're eq, compression, limiting, output volume. > Are there any recommendations for this kind of Linux > software? If I'm correct about what your cousin is doing, broadcast audio--live or recorded, then JAMin (jamin.sourceforge.net) is the correct solution. JAMin is a mastering/sweetening tool that includes; eq, three band compression, limiting, output stage and crossover. It will definitely help raise the floor for subtle sounds and hold the ceiling on louder sounds while increasing overall output and you can stream through it live. The objective is to process audio so it sounds appropriate while being broadcast from a pair of 2" television speakers. You can to save presets that will apply to specific rooms, mics and source types so it'd give you a variety of starting points tailered to specifics. JAMin is an incomplete beta stage tool but it'll do everything you need for broadcast audio requirements and it's as stable as your jackd environment. You'd be well advised to design and carefully test a jack solution. It's a low latency realtime data server and on a poorly designed or configured system will cause problems. IMO, a well designed system would cause broadcast audio processing to become almost invisible. ron > thanks > > Adrian > > > -- > Adrian Gschwend > @ netlabs.org > > ktk [a t] netlabs.org > ------- > Free Software for OS/2 and eCS > http://www.netlabs.org > __________________________________ Do you Yahoo!?
