Small/efficient mp3 decoder in C

mad mp3 decoder

Has someone experience with mp3 decoders written in C?

Which one is the smallest by means of text/bss size?
And which implementation is the fastest for 32-bit systems?

mp3 decoder c

This is a nice thesis
check appendix D : the c code optimezed to be used with a DSP.

mp3 decoder in c

I know this project...but my target isn't a DSP (o;

Normal 32-bit CPU running around 120 - 150MHz....

Hmm..maybe I'll check the uclinux sources applications...but want to avoid the kernel overhead...

The SOURCE code allows to compile in both OPTIONS DSP and NOT DSP .Which is basically to OPTIMAZE the floating point operation ,But it should compile in a BROAD type of architectures ,ARM ,,and even a fast 8051 like the cygnal ..

Hmm...well...long time ago I've visited this website and checked for any updates (o;

Have you tried it on several architectures and can you say something about performance?

 

[eltonjohn]

No the reason that i got interested is a little more complicated .. I wanted to use MP3 C code to convert it to HANDELC and sinthetize it in hardware ,, But i will probably use that as a student project next scholar year .

I also took a look atk mpeg321 and mpeg123 .. 321 is much more smaller than 123 .. But over all the smallest is the WITNEY one !

Cheers

Honestly target is a softcore in FPGA (o;

I threw away the stupid idea to use a US$800 FPGA to do simple mp3 decoding (o;

 

[eltonjohn]

You see ...... i said student ..project .. no money involved ..
but is a nice way to compare approaches in DSP, and FPGA .. The price only depends ultimatly on the quantity ,

Have you seen the vorbis tools?

Really, ogg suits more the student/personal projects than mp3.

Small?? After ported to Microsoft Visual C++, winxp say it uses 2MB of RAM

Anyway the thesis is indeed very informative and most importantly it is working! Very picky on the mp3 files though especially if the ID3 tag is located at the begining of the files.
