[linux-audio-user] How to get good vocal sound

I've been struggling with a technique problem. How do you get your vocals to sound good? I know that you can't make a silk purse from a sow's ear, but you can make the best of what you've got. What combination of plugins and settings do you use to get the best sound from vocals particularly in Ardour? I know that this is one of those subjective questions for which the best answer is try it out yourself and find what sounds best, but there are so many plugins (an embarassment of riches), each of which has many settings, that a brute force search of all the combinations would take forever - not to mention that after a while, my poor ears become exhausted with the effort and refuse to hear differences anymore. So what I'm really looking for is good starting points to work from. One combination that I like is GVerb to get depth and L/C/R Delay to get width. Even with those two getting the settings right takes time. For comunication, I've included a jack rack with some settings I've found that work OK. I would love your critiques and suggestions for other setups. Regards, Bill
