please i need this code to hide and extract data from a wave file
You want to hide some data into a wave file, and expect that people don't see it ? if so, what kind of data (their structure, not what they are)
or just want to load and play a wave file from delphi ?
What you mean saying "hide"?
If you need to write some data to wav file then RIFF format support this.

You should be able to append to the end of the file without affecting it. I'm assuming you still want to be able to play the file with the extra data in it?

You are mistaken. It contradicts the RIFF protocol.
And many players will show an error.
I thought Kazzaa and those other applications stored information about the file by appending data to the end. The header of the file should dictate how much data the player needs to read. However, some formats may be different.
Thanks for the correction.
