Re: Need to reduce file size

Tech-Archive recommends: Fix windows errors by optimizing your registry

Are you sure it's a WAV file ? What's the file extension for it ?

When I try to convert the file using Windows Media Encoder, I get an error

It must have something to do with the codec. Maybe I'm not saving this file
or capturing correctly to begin with.

Hello all,

I have a delema and need some advise. I need to record a voice
presentation
that is 27 minutes long, up load it to a website using dialup and be able
to
play it from the site via a link. My problem to start with is, the file is
25meg after being converted to MP3. (wav puts it at a little over 200
meg).
Can I reduce this file size any at all.


If you still have the original WAV files, probably.

MP3 ain't that great at low bitrates (under 48kbps). However your
files will be coming in at about 125kbps which is overkill for voice
audio, which has a maximium frequency response of 8khz.

So in your case you might benefit from using windows media encoder to
create WMA Voice audio files :

http://www.microsoft.com/windows/windowsmedia/forpros/encoder/default.mspx

You'd skip the wizard part of the program. Instead, cancel out of that
when it starts, and go to the Properties button. Step by step :

Click Source From File (choose your WAV file), selecting *only* the
audio checkbox.

Next screen, choose the Output tab. Untick 'pull from encoder', tick
'archive to file'. Select somewhere to save your file to.

Next screen, select Compression tab. Choose 'File Download (computer
playback), then Audio : "Voice Quality Audio (CBR)".

Click the Edit button, then the 7kbps Tab in the popup window. Instead
select 10kbps / 11khz audio. Click OK then click Apply.

Go to the File menu, choose Save As to save these encoding profile
settings. Now you can start the encoding process (which should be
pretty fast, a few minutes), using the green button.

The resulting file ought to be about 2.5-3 megabytes, but still
provide acceptable voice quality playback for listeners (who will now,
though, be restricted to playing back on windows media player)

You can optionally go back to the settings and move them up to 12 or
16kbps if you recorded using good microphones in a room which was
acoustically good (ie minimal echoes and background noise).
