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

Time Duration In MAD.
by Senthil Nathan G 11 Jan '05

Hi All, NewBie Question : How does one find the time duration without decoding an MP3. Is it possible. (Without looking at any header also since this might be wrong ). How do I decode a particular time period ( say from 30 sec to 45 secs ) of a given MP3 in MAD. ( or where should I look to find the answers ). Thanks very much for all help. Senthil ( INDIA )

Hello everyone! How can I change the sampling frequency from 44khz to 48khz easily in minimad.c, that is, in the highlevel api? Thanks, steels. -- ______________________________________________ Check out the latest SMS services @ http://www.linuxmail.org This allows you to send and receive SMS through your mailbox.

S: faster decoder than libmad
by jens-lippmann＠t-online.de 02 Jan '05

Hello all! I'm looking for a MP3 decoding lib faster than libmad, probably solely written in Intel assembler. I currently use libmad 0.15.1b to stream MP3 files into WAV sound buffers and I need to improve the performance. The mere task of streaming a single audio file saps about 11 milliseconds (@1.8GHz). libmad uses inline and asm here and there, but the costliest parts (frame decoding and synthing) are written in C, optimized for speed but still C. So, my question is if there's anything freely available that decodes faster than libmad? kind regards Jens Lippmann
