Bad audio quality in Moodle Kaltura recordings on iMacs under ambient sound conditions. A running log (closed)
- Symptom: See title.
- 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).
- Possible solutions:
1st choice: is there a way for the admin to override this permanently? 2nd choice: is there a way for the end user to override this on a case-by-case basis?
- "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?
- Try the flash settings by right clicking in the video window, selecting the microphone icon, then choosing the external (= non-webcam) microphone for input.
- 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).
If you can handle – or actually prefer the increased stimulus of – a monolingual dictionary resource, this one looks nice – with its parallel display of dictionary entries, etymology, common collocates, and empirical use in KWIK format – and well-founded: Based on the Wörterbuch der deutschen Gegenwartssprache (WDG) and providing access to many corpora that document empirical use (including frequency and longitudinal information) of the language – modern German, including spoken language and many newspapers, altogether comprising about 1.75 bn words.

Downloading the originals from the most helpful site (also available by direct download) created by Tim Xie for the California State University, Long Beach, and applying my bash shell script from here, then generating your own speed-differentiated versions, seems to difficult for most users. Even better, instead of perusing the above links, you could just hit my server once and download the whole lot of post-processed animated Gif files with different speeds from here.
Advanced language learners can test their English, German or Spanish proficiency in 3.5 minutes here using Exhale
Go here and click English or German, or (also requiring only 3.5 minutes to take, but more for manually grading your test with this answer key) go here for Spanish, if you want to to take a simple quick vocabulary test that has been shown to correlate well with general proficiency. You can find more info here on English and German, and here on Spanish.
Installing is easy (our example is Wikipedia): Right-click a word, pick “define” from the context menu, the click download in the side pane for the app you choose.
However,how o I change the default lookup that happens on double click on a word?
