This might work to achieve gapless looping: Once you've loaded the audio assets (an mp3 file, swf file library assets, etc.), copy the raw sound data into a ByteArray. Then to play it back you create a duplicate of that ByteArray and feed it to a new Sound object when it throws it's SampleDataEvent event. Once you've used up the ByteArray, duplicate it again and keep feeding it to the Sound object.
I've been messing around with this, off and on, for a while to try and loop a simple sine wave audio data that I've generated. It works pretty well, except that I always get a little 'pop' whenever the next loop starts.. possibly because the phase of the end of the previous loop doesn't match the start of the next one. ------------------------------ Andrew Murphy Interactive Media Developer amur...@delvinia.com Delvinia 370 King Street West, 5th Floor, Box 4 Toronto Canada M5V 1J9 P (416) 364-1455 ext. 232 F (416) 364-9830 W www.delvinia.com -----Original Message----- From: flashcoders-boun...@chattyfig.figleaf.com [mailto:flashcoders-boun...@chattyfig.figleaf.com] On Behalf Of Jim Andrews Sent: April 29, 2010 01:52 am To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] gapless looping of external mp3's I'm new to the list. Does anyone have experience with gapless looping of external mp3's in Flash? I'm having probs with it. I read http://www.compuphase.com/mp3/mp3loops.htm . There's even a section in there about gapless looping in Flash. But I'm not sure how old that page is and if there are better methods now than what's described there. I have done some previous work with gapless looping, but it was all in Director, such as at http://vispo.com/nio and http://vispo.com/jig/arteroids . I'm just learning ActionScript now. ja _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
