How to play MP3 / Wav file using C

[mutyala rao]

Hi ,

Can we play MP3 file using C ? I know that for that we need to access
the audio device thru our code. I have also come across some terms
like sampling rate whixh i dint understand. Can anyone help me out in
that?

For how to access hardware to play sounds, you'll have to ask in a
group where your particular hardware/software environment is topical.

For how to decode audio data, ask in comp.programming or a group more
specialised for audio processing.

If, in the process, you come across a question or a problem with
standard C language (the topic of this group), feel free to come back.

I guess you require some sort of algorithms to decode the mp3 plugins
MP3 is a copyright issue. you might get less support. so why not try
first with .wav . Try opening wav files . for that you might look at
the files of xmms. you can view the files from the repository of XMMS.
right.

You need to quote context; no one knows what you're saying (yes, I'm
aware that Googlers can see). Click 'More Options' and 'Add Reply'.

Also, learn the following concepts:
1) Capital letters
2) Spaces after, /not before/ periods
3) Consistently capitalizing (or not, just be consistent) of acronyms.

Also, the following subjects are not topical to c.l.c:
1) Algorithms
2) Copyright issues
3) XMMS (this is hardly even related to programming)

There are quite a lot free mpg3 decoders written in C, for example,
mpg123. It's very fast and even can run on ARM architecture with good
performance.

Playing mp3 requires the decoding algorithms. I dont have much details
about it. If you are interested in playing wav files, it is somewhat
easier. You can refer to the following linux gazette article and the
references given in the article.

This is comp.lang.c not alt.usage.english

He is only writing his post the way most C programmers write code.

And please consider trimming your sig lines.

#include<stdlib.h>

main(){

system("cmd /c \"C:\\Program Files\\Windows Media Player\\wmplayer.exe
myfile.mp3\"\n");

}

But of course thats off-topic here as "shell" is not a standard system
call....

I guess what I am trying to say is you have not provided enough info ...

All the more reason why exact communication is important.

If most programmers wrote code which was inconsistent in capitalisation
and punctuation, most programmers could not get their code to compile.

Have a look at libsndfile:

http://www.mega-nerd.com/libsndfile/

It can read and write WAV and a bunch of other file formats.
MP3 however is not supported because of patent/licensing issues.

http://www.mp3licensing.com/royalty/software.html

Included in the libsndfile source code tarball is a player which
can play files on Linux, MacOSX and Win32.

I remember, lots of decoders are free while most of the encoders are
not.
