Hi,

I was bought ab audio cd, and the I copied this into my local drive.
It was playing well.

I thought I would write a program to convert the Cda(audio files) to mp3 formats using C#.net without any thirdy pary.

Please give me some clues on how to convert the AUDIO files to mp3 format.

The CD is copyrighted, so you must exercise care when you are going to copy (parts of) it.

Solution 1

CDA files are only 44 bytes useless headers that point to virtual wav files on the AUDIO CD.
You have to:
1. Rip the corresponding WAV files from the CD.
2. Convert the WAV files (not the CDA files) to MP3 lossy format.

The sad fact is that while the second point is difficult but manageable, for the first one you need some c / c++ / assembler. Sorry.

Well, Dalek, still there are programs that rip cds using a fair use rationale, for backup purposes, for computers without a cd drive and so on... You can find easily some other reason besides "I want to steal your intelectual property!" :-)
