PowerPoint [97] slideshows can utilitze WAV or MID audio files (only). WAV files are BIG and can bloat a slideshow file (.pps or .ppt) to an unruly size which is time-consuming to download.

I use E-soft's Audio Edit utility to create small .wav files, but the quality really suffers.

Here's a 10-second Andy Williams clip recorded at 44,100 Hz, 16-bit Stereo:
AW44-16 (1.7MB)

Here's the same clip recorded at 8,000 Hz, 8-bit Stereo: AW8-8 (117KB)

You'll notice the "S" sounds on the lower quality clip have a "Shhh" distortion. Very noticeable and unpleasant.

My question to you folks is "What filters or effects can I use to minimize this audio distortion and yet retain the smallest WAV file size possible?"

Hey Uncle Richard,

I have had a few experiences with audio and I use this one for web and it is still fairly clear. I see you have used stereo and that adds onto the file size. I use the following Settings:

22 050 Hz
8 Bit Depth
Mono

Making it mono will reduce the size. I thought Powerpoint 97 can play mp3's ??

Have a fun and computing day,
Grove :cool:
