This is a bug in the 0.9 SoundKit. To get around it, you should use the Application event loop (with the "run" method) and also use the Sound class delegation mechanism to get the sound to repeatedly play itself. In the simplest case, you'd have a subclass of Application that looks like: #import "TestApp.h" #import <soundkit/Sound.h> @implementation TestApp - appDidInit:app { [[[Sound newFromSoundfile:"foo.snd"] setDelegate:self] play]; return self; } - didPlay:sound { [sound play]; } @end The above code, coupled with an IB-generated main program and Makefile will work fine. The advantage of this code is that your events (such as hitting the "Quit" button) will be detected and processed. And of course it will play the sound more than 3 times.

The SNDPrepareToPlay routine seems not to have any effect. Is there a workaround for this? Would accessing the Mach sound driver ports directly be faster? I'd like to avoid writing DSP code if possible. Will this be fixed in 1.0? Will 1.0 support arbitrarily long WaveTables? (This will solve my problem.) The sounds I want to loop are on the order of a few seconds. Has anybody done this? Bill Thibault csuh!tebo@lll-winken.llnl.gov >From: rrr@cup.portal.com (Roger Rock Rosner)

The SNDPrepareToPlay routine seems >not to have any effect. Is there a workaround for this? No. 1.0 will provide seamless sound playing by allowing you to queue up sounds at the sound library level. You will also be able to record into different objects without losing any samples. The 0.9 sound library does not allow queueing. >Would accessing the Mach sound driver ports directly be faster? Yes. Unfortunately, this is highly discouraged at this stage, as this low-level interface is changing for 1.0. Ali Ozer, NeXT Developer Support aozer@NeXT.com >From: ali@polya.Stanford.EDU (Ali T. Ozer)
