you can decrease the size even more if you use some kind of compression
I suggest you use Audio Components from peter morris
these are not free, but the version 1 is !
he has discontinued the support of version 1
I'll ask him if I can make the version 1 publicly available
I use these compos in several of my projects and they work great

they're really simple to use
simply put a TWaveIn component on the form and set the output format
also with examples

My new components also let you read/write wav files very easily. You can then compress them using any installed codec and windows will still play them.

So you can sample them down, or preserve quality and just change to a different format (mp3, adpcm), and they will still be .wav files!

There is even a demo (with source) to do exactly that.
