Release Notes

  • Cameras and other Video Hardware:
    • Most Firewire cameras should be able to send video. Verified models include the iSight, iBot, and Panasonic DVX100a.
  • Audio Hardware:
    • You should either use the built-in audio device or a USB audio device that has been verified to work (listed below).
    • To use built-in audio, set it as the default audio device in "System Preferences", "Sound". Then, plug in a standard microphone* or if you have a laptop, you may select the built-in microphone.
    • If you change your audio device while the rat audio program is running, you'll have to restart it for your changes to take effect. You can do this by pressing the "Go" button in the VenueClient or by disabling and reenabling audio.
    • Be sure to prevent echo by using headphones or an echo-cancelling device.
    • Some USB microphones have been verified to work. Verified models include the Griffin iMic and the Plantronics DA50, DSP-100, and DSP-400.
    • The iSight microphone does not work well yet with the toolkit. It is recommended that you use it only for video, since using its microphone will cause your voice to sound lower and drop about 8% of the sound (due to differing sample rates).
      * If you have a G5 Power Mac (tower case):
      The line-in port does not work with standard computer microphones unless a preamplifier is used. Old Apple microphones and adapters (i.e. plainTalk) are also Not compatible with the G5 tower.
  • Encrypted venues are not yet supported and will crash rat, the audio program.

*** With PowerPC (not Intel) macs, using OS X Tiger's default wxPython install (version 2.5.3) may prevent the VenueClient from starting. To prevent this, it is recommended that PowerPC (not Intel) Tiger users upgrade to a 2.6 version of wxPython.
