Hello, everybody. Sorry to disturb you all.

Currently, I have a speech recording and playback software developed by Microsoft Visual C++ 6.0. The software is used to train children with speech problem and scores will be calculated and showed at the end of each practice session. The software is able to record and playback real-time.

Children use this software at home and save their practice records in a single floppy disk. Then, children will bring the floppy disk with practice records inside when they return to our centre. There are 20 wave files that must be saved in a single floppy disk. Due to space insifficiency, one floppy disk is 1.44M in capacity.
Total size of 20 wave files = 20*188k = 3,760,000 bytes
Total floppy disk needed = (3,760,000)/1,440,000 = 2.6 floppy disks
But, I must save all the 20 wave files into a single floppy disk

Our problem is we are not able to save all 20 wave files in a single floppy disk. We cant afford a CD-RW for each child and we must use floppy disk. The solution is we have to compress the wave file to save the files in a floppy and decompress the files back to wave file in order to listen to how the children practice at home.

I am totally new to this as the software is written by one of my previous friend who worked together with me in a voluntary speech rehabilitation centre. We need this software to train children in the centre. I work part time there.

But, my problem is how to call any CODEC dll into correct place into my current project platform without causing any bugs? Please forgive me if I have asked a very silly question, I am sorry. After I have added the cpp and h files into my current project paltform, I dont know what should I do next.

My final destination is to save all 20 wave files in a single floppy disk. I didnt restrict that I must use compression/decompression methods but I dont know what else should I use.

Hope you can give me some guidances on how to do it or you please link me to pages that help me to do so. I promise I can learn as independent as possible but I really need your guidance at this very beginning, please.

Please, I really appreciate all your help.

Anybody knows? Please give me some advices, please

Sorry to disturb, May I ask?

I was confused with the acm driver and as a newbie, I really coulndt implement it without any bug after finding the driver and doing the two conversions. I just want to call the third-party software.exe to help me do the compression and decompression part. Do I need to call the dll? Or, Can I just call the .exe from my software?

Sorry for causing any confusion, I was not clear with dll before I put this thread, after I read the pdf about dll, I think that maybe I dont need to call dll but just call the exe.

Please forgive me, I apologized for the trouble caused by me.

Do you think it is possible to call any CODEC software exe from my software? Which one is easier for a newbie like me?

But, I dont know how can I do so, do you mind to give me some guidance? Please, Please forgive me for my ignorance. I try my best in doing it. Hope you can teach me some. Please.
