Calling play() with a startPosition, and then calling stop() on the SoundChannel instance will work fine as long as the timing doesn't need to be too precise, and you don't mind slight glitches (pops or clicks) at the start and end.
If you want sample accurate start/end times, you can use a couple of new capabilities in FlashPlayer 10, namely the ability to extract audio sample data from an mp3, and the ability to send arbitrary audio data to the output in response to a SampleData event. Using these APIs, plus lots of other code, you can do some pretty sophisticated audio processing (see for example, http://labs.sonoport.com/audiostretch/). In response to the original query, using Sound.extract and SampleData event, plus a bit of additional code, you could play an mp3 from any sample position to any sample position, and even apply a smooth ramp-in and ramp-out to prevent any glitching. Andre Michelle's blog has some great examples of how to use the FP 10 audio API, for example: http://blog.andre-michelle.com/2010/playback-mp3-loop-gapless/ -Gerry Beauregard Lead Software Architect Sonoport.com On 2010-05-11 , at 03:45 , Glen Pike wrote: > Hi, > > The Sound "play" method returns a SoundChannel instance, which you can call > stop() on to stop the sound. > > Glen > > Jim Andrews wrote: >> http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/Sound.html >> >> >> The above URL is the main page to acquaint yourself with concerning the >> Sound class in ActionScript 3.0, apparently. >> >> If you scroll through it, you'll see some example code. >> >> You'll also see the 'play' method under 'Public Methods' and, in the >> documentation of the 'play' method, you see that it takes a 'startTime' >> parameter.
