MP3 Decoder

Started by Gugan Thoppe June 12, 2009
I am building a mp3 decoder.

I have understood (correctly or incorrectly?) that there are 576 frequency lines whose amplitudes are encoded using the Huffman tables. These 576 lines have been broken down into 5 regions namely region0, region1, region2, count1 and rzero. The first 3 regions constitute the big values.

I am unable to decipher the widths of the above 5 regions using the ISO documentation for MPGAUDIO. I am assuming that I need a BandIndex table to decipher the above details. Please help.

That's because it has to be accepted by a moderator. The moderators
delete a lot of spam that nobody wants to see, it makes it easier to read
the whole board.

There will be a delay because sometimes moderators are sleeping - we all
live in various time zones around the world, have day jobs, and families.
We'll get to it eventually!

Patience, persistence, truth,
