Hi Guys,

Few days back I posted a query regarding the frame sync in MP3. The problem is resolved and now I am a step ahead to it. In my application I got the FRAME HEADER as well as SIDE INFORMATION of a particular frame. Now I am in a new problem:

The problem is as follows:

I have got the side information in a structure which looks like below

struct SIDE_INFO {
int main_data_begin;
int scfsi[2][4];
int part2_3_length[2][2];
int big_values[2][2];
int global_gain[2][2];
int scalefac_compress[2][2];
int window_switching_flag[2][2];
int block_type[2][2];
int mixed_block_flag[2][2];
int table_select[2][2][3];
int subblock_gain[2][2][3];
int region0_count[2][2];
int region1_count[2][2];
int preflag[2][2];
int scalefac_scale[2][2];
int count1table_select[2][2];
};

I have got all the fields correctly in my application for each frame. Now my question is which all data in above structure is huffman codded? I know for experts over here this might be a silly question (but for me no question is silly untill it enhances something in ur knowledge)

None.

Why don't you check out the specification (or one of its drafts which are publicly available for free)?
See ISO 11172 on mp3-tech.org.
