People often forget about QuickTime Player on Mac OSX.It's been there all along. I keep an alias of it on my desktop.Quickly opens audio files, pressing Command>I (Inspector)then tells you the sampling rate, bit depth, channel format, data size, data rate, and duration.All while listening to check it.Keeps one from having to open iTunes and being directed to the Store!You can use it with video files as well.JT
