How can I grab audio tracks with Visual C++? I have to access the CDROM, get the number of tracks and let the user select which tracks to copy to the harddisk. Are there any tools or SDK's which covers this topic?

16-bit or 32-bit Visual C++?

I did some looking around the net and found these things you can download:

ftp ftp.microsoft.com
user: anonymous
password (your email address)
cd \softlibs\mslfiles
bin
hash
get singacd.exe
get playcdno.exe
get playcd.exe
quit

Singacd has the source code to let you play a cd

Playcdno has more stuff on controlling CD's.

They come with source code and executables (pre built).  They are self extracting files.

You should also get ahold of Document Q81869 and Q81871 from the Microsoft Knowledge base.  YOu can fax for it via

Dial  (800) 936-4300.
Select the Win32 Software Development Kit.
Press #1
Select the delivery method, fax.
Enter your three-digit area code and seven-digit fax number on your phone keypad.

When prompted, enter the number of the Item ID and press#, for up to five items.


the key apis to use are:

mciSendCommand
and mciGetErrorString

mciSendCommand will return 0 when its successful.  If you call mciGetErrorString you can figure out whats going wrong.

Hopefully this will give you a good start on the whole process.

Perhaps I didn't exactly explain what my problem is.

Getting the number of tracks is easy (I'm using an activex-control for getting this information), but I want to read the tracks on the cd and write them to my harddisk (wav-files). I'm using a cdrom which supports audio reading (Plextor 12/20Plex). I tried to read the audio tracks by sending scsi-commands to my cdrom, but I think the commands for reading audiotracks are non-standard. If so, I only need to support the Plextor drive.

I'm using 32-bit Visual C++, but it doesn't matter if your sollution is written in any other language.

But I could not find any 32-bit source code to do so.

I found a working source code. It uses simple ASPI-commands, but before reading audio tracks with the read command you have to set a mode page of the cdrom to proper values.

If somebody is interested in it I can mail the source code.

Does it work with IDE CD-ROM drives? Can you please tell us the URL for downloading it?

I don't know whether it works with IDE drives (I don't have any). I also don't remember the URL where I found the code, but I can explain it:

First you have to have to set the sector size to 2368 (CDDA). This is done by calling the ModeSense command (0x1a) and setting the sector size to 2368.
Then you can read the blocks by calling the Read command (0x28). I didn't try to use the ReadLong command (0x3e).

I did this using a scsi-monitor program which I found in a book of SCSI. Now I try to implement this in my Visual C application, but I'm not very familar with ASPI-calls yet.
