dividing WAV file into four smaller WAV files

Question

While I can use Gmail to send about 10 MB attachment and have done so for two lectures recorded digitally as WAV, I now have a third WAV which is over 40 MB and it looks like Gmail 'chokes' when I request the attach (to Send). What kind of tool (if any) am I able to use to create four (or more) standalone WAV files each of which may fit within the 10 MB (or so) size limit? Our situation is that a graduate student with both knees / legs in rehabilitation is having lectures recorded and wants them sent to him in another state (from Virginia to the other side of Maryland).

MusicMatch has a file convert feature to convert WAV to MP3. If needed it can be converted back at the other end. Your 40 mb would be reduced to ~ 5mb in MP3.

I have a music 30.2 WAV file and it is 3.8 in MP3. When you did the conversion did you have the source box set as Wav and in the other box MP3 from the pull down menu? Also there is a slider for the bit rate.

I did the file conversion (after downloading and installing - Basic) and it went from 40 MB as WAV to 160 MB as MP3

My son (13) says to download Goldwave and use that. http://www.goldwave.com/ You get like 3000 "actions" in the trial.

A very simple utility which can both compress wav files to mp3, or just to chop them into manageable *.wav lengths, is the Microsoft sound recorder (sndrec32.exe), found in C:\WINDOWS\system32, at least in XP.

In addition, there are freeware audio editors available. http://audacity.sourceforge.net/ (see http://audacity.sourceforge.net/help/faq?s=install&i=lame-mp3 for exporting to MP3) http://www.nch.com.au/wavepad/index.html

File size in general is dependent on the MP3 bitrate used during the conversion. Which bitrate did you use?

If you have iTunes, it will also convert to MP3.

To cut a wav file into sections, I use either Wave Studio, which came with my Dell OEM Audigy 2 sound card, or Sound Editor, which is part of Roxio Easy Media Creator suite 8 (which costs $$)
