Many thanx Glen I'll take a look. I know number in mp3frame is fixed (multiple of 576), but still i'm not sure, eg. having a regular test case produced from flash ide, it show up:
soundItem soundID="1" tagSize="1263" format="mp3" rate="22KHz" sampleSize="16bit" type="stereo" sampleCount="1012"> 1012 % 576 != 0 - is it sampleCount mandatory and must be precise about number of total samples in audio data? - how is it computed if there are incomplete mp3frame? - am I on the wrong way? Miss some critical info or looking at pointless details? Suspect have to get much test cases and look closer to mp3 handling code... :) Jaco ----- Original Message ----- From: "Glen Pike" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, April 26, 2006 3:50 PM Subject: Re: [osflash] mp_3 sample count & header info > Hi, > > Sorry if this is off list - I am at work so popping > my osflash account, but replying from another. > > I had a look at a couple of things - I did some mp3 > stuff a while ago. > > I think the number of samples in a frame is constant > - see here > > http://www.mp3-converter.com/mp3codec/frames.htm > > I also had a go at reading MP3 headers with PHP a > while ago and found that this package was quite > useful.
