Where the hell is definition of struct id3_file????
by tj 29 Sep '06

29 Sep '06

In trying to learn how to use libid3, since there sems to be no documentatio. I am looking at soure trying to figure out how to use it. The first problem is the practically every call uses a pointer to a "struct id3_file" . Now, the problem is that there is no definition for id3_file structure in any .h file. I finally found it in file.c, a source file. How the hell are you supposed to use it in your app when the prototype is in a package source file? Seems that something is really broken here. tj

MAD library for TI-54X DSPs
by balaji shanmugam 20 Jul '04

20 Jul '04

Hi I am trying to port the MAD library for the TI-54X DSP and running into tight timing issues. When analysed, I found out that the 54X DSP takes more instructions to perform LONG calculations at the SYNTHESIS FILTER Bank stage as it is a 16 bit processor [but with a 40 bit accumulator]. As it is required to perform 72 times the DCT32 and the remaining MATRIX calculations at the SYNTH stage, I like to optimize the synthesis filter bank. I am not sure about using the Q28.4 format being used by MAD. Is there anyway we can use the Q15.1 format for the calculations? I like to know is there any hints or clues for the LONG calculations that I can make use of during my 54X porting phase. Also any thought about using the NORM instruction to round the final samples to 16 bit will be helpful.

Hey all, I'm having a problem with some of the MP3s I am decoding having a lot of clipping/popping. Any ideas for fixing this? Deven
