Jimmy,
Now your question can certainly open a can of worms … Audition is the only audio program I have used and my music and sound tracks have been broadcast on radio and tv to my complete satisfaction … I am sure if you asked 10 differnt people who have had any time recording digital audio you are going to get 10 simular but differnt answers … From my experience with this program over the last 8 + years, (was cool edit) I can say yes it will do the job you want and do it very well … As for a keyboard or synth, it depends on what kind of sound you are looking for … For the website you will have to compress so I would start with the best possible recording I can get, here asgain some will tell you to use as high a sample rate as you can but I feel 441 will be just fine at 32 bit with a mixdown to 16 … Good luck with everything ………….. WILLIE
