Hi all,
I'm trying to play an MP3 using the Windows waveOut interface.
I have no idea how to do that, but I have a code that can play a wave file 
using buffers.
I would do the same but for MP3 files instead of WAV files.
Anybody can help me?

Thanks

Lapo

Thanks for your answer.
The problem is that I need to play each mp3 chunk separately and I think 
using TMediaPlayer this is not possible because it does all inside.
I read many tutorials on the net about waveOuy interface, but all for raw or 
wav file.

Thanks again.

Playing back a MP3 is not so easy to do. You'll need to use the Audio 
Compression Manager (ACM) as well as waveOut. This also requires the MP3 
codec to be installed, but I think that WMP installs that.

Basically you'll need to create a AM stream that converts the MP3 audio to 
PCM audio, and then you feed that into waveOut. Look up ACM and waveOut, 
you should be able to find something.

Hi Lapo,
 I can read them very easily by using a component I wrote based on 
DirectShow technology, it can read wma, wav as well and any other format you 
have a directshow filter installed for.
You can email me for further questions, I'm sorry but my studies does not 
allow me to check my dear forum so often as I would like:(
Regards,
Stefano B.
