My iMac has enough USB devices plugged in that I had to buy a large USB hub just to handle the overflow. Thanks to USB headsets for Skype and USB audio mixers and microphones there are times when I’m not exactly sure which device is plugged in where and what the sample rate settings are. Apple doesn’t make it a simple process to find out, either.
What Mac audiophiles need is the elegance of AudioMate, a Growl and Notification Center aware utility that lets you know when an audio device is connected or disconnected, or when the audio sample rate has changed.
Not only is AudioMate useful for telling you when changes are made, it also lets you change the sample rate for any device with a click. This can be incredibly handy when recording audio from multiple sources.
AudioMate doesn’t seem to care whether the aukio device is USB or FireWire. When a device is plugged in, you get a Growl or Notification Center pop up alert. Ditto for when a device becomes unavailable (which happens too often), and Audio Mate remembers the settings and selection for the device when it comes back online.
There’s even an option to display a selected audio device’s sample rate in the Mac’s Menubar.
This is nicely done and inexpensive. And, it would be perfect with one extra control for the Mac’s system audio input and output device.
