Reduce size of wav files

[Stan]

To email a PowerPoint slide show with music only wav files may be used and
when I convert an mp3 to wav it usually is about 25mb in size. While I can
get PowerPoint to accept a wav file up to 50mb, my server won't accept that
large a file.

When I receive a PowerPoint show with music the music is always less than
500kb so there is some way to create a small wav file.

When I compress a 25mb wav in XP it ends up at about 23mb which is still too
big. Do you know how I can get it down to an acceptable size?

Hi Stan If you go to our Hints and Tips page here
Improve your skills - http://www.technologytrish.co.uk/ppttipshome.html
the section on "How to embed an mp3 " will help and also the "why won't my
song play whem i email it to a friend"

Thanks for the info. Will check it out and hopefully don't run into any
problem. Sounds great.

Stan;

You may want to consider resampling your wav file using Windows Sound
Recorder (sndrec32.exe). There used to be a tutorial around explaining the
steps and recommended settings. I just can't put my hands on it right now.

Michael,
If you do ever find that tutorial I would like to see it. Meanwhile, how
would I "resample" as you suggested. I am not sufficiently versed in such
techniques. TIA

this is off the top of my head, but it is pretty close to the way that the
tutorial went.

Click the <Start> button
Click <All Programs>
Click <Accessories>
Click <Entertainment>
Click <Windows Sound Recorder>
Click <File>, <Open>

Select the wav file you want to edit.

<Click> On properties and look under Audio Format and it will indicate the
current file setting. In the Choose From drop down window select <Playback
Formats>
Click <Convert Now> leave the format at the default <PCM> the select an
attribute around the 11.025 KHZ, 4bit stereo and select <OK>. Listen to you
conversion and if it sounds okay, save your file with a new filename and
then insert it into your presentation.

I downloaded the software and it's not the easiest thing to follow but it
did work for me. I will do it again and hope I can remember all the choices
I made. Thank You sincerely.

Michael,
How did you remember all those steps! You are something else. There was no 4
bit option so I used 8 bit and it worked perfectly. Thank You most
sincerely. This is a great help.

Stan,

one last tip.... if you convert the .wav file from a stereo to a mono file.
