I made a couple of attempts to incorporate the 'prepare' command into the scripts Scott Rossi (Thank you, Scott) supplied to play a sequence of audioclips. First, I tried to 'prepare' the next audioClip right after playing one audioClip: on runAudio if the sound is "done" then if the uCurrClip of me > the number of items of fld cliplist then set the uCurrClip of me to empty exit runAudio end if play audioClip (item (the uCurrClip of me) of fld cliplist) set the uCurrClip of me to the uCurrClip of me + 1 prepare audioClip (item (the uCurrClip of me) of fld cliplist) end if send "runAudio" to me in 5 milliseconds end runAudio The 'play' commands begins playing its audioClip, which is quickly interrupted by the 'prepare' command playing the same sound. (Putting a 'wait until done' after the prepare command simply results in the complete sound being played twice and taking twice as long.) Next, I tried to 'prepare' the complete set of audioClips in the initial mouseUp handler: on mouseUp if the sound is not "done" then play stop set the uCurrClip of me to empty exit mouseUp end if repeat with i = 1 to the number of items of field "clipList" prepare audioclip (item 2 of field "clipList") wait until the sound is "done" end repeat set the uCurrClip of me to 1 runAudio end mouseUp The successive 'prepare' commands plays each of the 10 sounds (presumably loading them into memory, as well) Then 'runAudio' plays the sounds at a rate of a little more than 500 ms per audioClip, when the audioClips are each 250 ms long. That rate (2/second), pretty erratic and about half what it should be (4/sec), is not significantly different from what I get without using the 'prepare' command. In summary, using Scott Rossi's scripts, Revolution could only play the 250 ms audioclips at a rate of about 2/second, and the prepare command did make it any faster. (I was running on a Mac PowerPC G3 220 MHz cpu under OS 9.0.4. Naturally, it's faster on a faster Pentium 4.) In fact, I can't tell if the 'prepare' command works any differently than the 'play' command! Keven suggested "you should try the "prepare" command, it will buffer audioClips before playback. Let me know if that works for you?" Well, it does not seem to work. Is this a bug? How is 'prepare' supposed to work? I'm still open to suggestions, but it looks like I'll have to work on extracting and combining the audio file data, as suggested by Geoff Canyon and Sjoerd Op 't Land (Both have supplied useful information that I still need to digest and apply.)
