Bad audio quality in Moodle Kaltura recordings on iMacs under ambient sound conditions. A running log (closed)

  1. Symptom: See title.
  2. Cause: While speakers of the 3.5 mm headset take over from the iMac speakers, when plugged in, the 3.5 mm headset micro does not disable the webcam micro. The webcam micro remains the recording source for Moodle Kaltura (mac os x.6, safari 6, flash 10).
  3. Possible solutions:
      1. 1st choice: is there a way for the admin to override this permanently?
      2. 2nd choice: is there a way for the end user to override this on a case-by-case basis?
      3. "The Califone 3066AV is compatible with both Windows and Mac audio outputs (but is not compatible with iMacs)." ("The Wow starts now!").. Do we have to tie up our boom and lavalier microphones for this?
      4. Try the flash settings by right clicking in the video window, selecting the microphone icon, then choosing the external (= non-webcam) microphone for input.

      6. Fail. The real culprit is the iMacs line-in audio-in for which you need a preamp to get it to work with analog microphones. Preamps seem to start at $40, but for that I can get a PC webcam (Microphone included).
