Reading MP3 file

[chaluva]

Hi,

I have mp3 file which need to be decoded. I want to decode this file by calling decoder. I need few clarifications for the doubts I have.

1. If the file is there in PC and I try to read it, how much of data I need to read from the file? Preciously what is the rate at which I have to read the audio data from this file? Is there any conversion formula available to know this?

2. Does it depend on the bit rate supported by the codec (MPEG-1 layer3)? If yes can somebody tell me the theory behind this?

3. If multiple bit rates are supported how different is to read a file as compared to single bit rate.

These questions may be very basic but I want to know these details as I am starting to work with codecs for the first time. Responses aare highly appreciated.

Best Regards

OK, u post this in the iPhone section, I dunno why.

Perhaps u have better luck in the HACK section.

But this is really a consumer-oriented forum, u probly have better luck in a programmers-type forum, don't u think?

You really are NEW!

Am gonna hazzard to guess your first step would be to google for "MP3 file structure."

Are u writing your own decoder? Why do u need a MP3 decoder when every music player on the planet has a MP3 decoder built-in?
