The metacard help went into some detail on available formats. If I
recall, AIFF was not one of them that could be embedded. But if you do
not want to embed and you are going to use QT and a player, then I would
convert to MP3, simply because its more universal (and then you can play
it on your iPod too!). You cannot embed MP3 though, so for embedding I
would use something like Next(sun) and Klaus just wrote that he likes
I notice you come from Hypercard. So in Rev you need to look at help
under "players" and related topics. It can be confusing coming from
hypercard. If the sound is not embedded you first create a player, then
"set the filename of player myplayer to mySoundFile". If you do not use
the full path of the file, it will look in the default folder. So use
the full path to be safe. Try:
answer file "what?"
put it into myFile
create player "myPlayer"
set the showController of player myplayer to true
set the fileName of it to myFile
choose browse tool
start player "myPlayer"
You can also play selected chunks of a sound file using the using the QT
units. For example, if you want to stop playing the file before the end
set the playSelection of player myPlayer to true
set the endTime of player myPlayer to myEndTime
By manually stopping a player (where you want it stopped) you can then
open its properties (property manager > player) and see the current QT
'time' unit. So it is very easy to find exactly where you want to start
and stop a sound. All of this is pretty well documented in 'help' but
look under 'players' and related and not 'play'. It's confusing coming
from hypercard, I know!
