Presumably the documentation that comes with this mythical non existent proggie would explain these basic points and advise the end user how best to set up the tests and apply any results... and optionally offer to tweak some system wide EQ settings based on results. I've had one formal hearing test and I had to step inside a small booth, close the door, and put on a pair of passive noise cancelling headphones... took about 15 minutes and I walked away with a crude printout and another appointment for the following year. I remember looking at the printout and thinking "how could I use something like Jamin to master what I generally listen to according to these results and automatically apply any compensation?". --markc ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
