Thanks, Bill -- I didn't know of a good utility for the Mac. However I
couldn't find a satisfactory Mac build of mpg123, having downloaded
tarballs and all. I didn't have time to muck around so I turned to
Google for help:
http://www.google.co.uk/search?q=quicktime+bash+script
which is worth serious study (when I've got time). For example:
Introduction to Open Source Scripting on Mac OS X
http://developer.apple.com/internet/opensource/opensourcescripting.html
helps you get started with utility "Terminal".
To debug suitable string args for (2!:1) -- launch "Terminal", and
copy/paste whatever works.
To cut a long story short, in the end it was so simple. Here for Gian,
and any wannabe Mac hackers like me, is the recipe...
Procure a very short mp3, or other format such as wav or aiff. Using
"Audacity" I created a test file: tee.mp3 (the letter 't' from
recorded speech). Place it in your "root directory" (mine is called
/Users/ianclark/ --the Mac facility "Spotlight" finds it). You can
place it in any folder, but then you have to get the path right. You
don't want too many unknowns first go.
Then the following works in J:
2!:1 'afplay ~/tee.mp3'
<...plays sound>
2!:1 'afplay ~/txe.mp3' NB. (no such file)
|interface error
| 2!:1'afplay ~/txe.mp3'
So you need (try./catch.) in case the file's not found.
As an alternative to afplay (Audio File Play) try:
2!:1 'open -a QuickTime\ Player ~/tee.mp3'
So you don't have to write out a txtfile and execute it as a BASH
script, like I'd feared.
Playing sounds in J isn't for entertainment. I need them as a
debugging aid while experimenting with timer events. If the timer
callback goes wrong the J session locks solid with smoutputs -- and
the yellow J won't stop it.
So I'm avoiding smoutput in favour of auditory cues. I think I'll give
my duty-cycle a heartbeat. :)
