Conserve disc space
I have converted a 90 minute lecture to a WAV and an MP3 file. Can I save more than 1 lecture to DVD or must I use multiple CD's (2 for each Lecture)?

Re: Conserve disc space
That's a festival of competing ideas.
You can get 80 minutes of stereo, high quality audio show onto a Music CD. This is also known as a Red Book Compact Disk and was designed to not accept compressed or variable length shows. 80 minutes and that's it. You need a Music CD Authoring Program to create this disk. iTunes will do it as will the latest Windows Media programs. Easy, Veritas, and Nero all work.
As a rule, carefully made Music CDs will play on any music CD player, any computer and many DVD players. They will play in your car.
You can make a CD that looks like a small flat hard drive. That's a Data CD. You can make a Data DVD that does the same thing only very much larger.
You can put anything on a Data CD or Data DVD. MP3 files, WAV files, pictures of your trip to Brighton Beach and your letter to your mum. If you put music files on a Data CD, it will not play in your car or most CD players.
Some newer CD players will play MP3 files placed on a Data CD. Most don't.
Everybody tries to compress their shows as tightly as possible with MP3 in order to get the longest show on their Music CD. The Music CD Authoring Program will chop the show off at 80 minutes, so you might as well leave the show as high a quality as you can.
Music CD sound format is 44100, 16-bit, Stereo, so if you set Audacity Perferences for those numbers, there will be no quality change at all when you make your Music CD.
The MP3 process always creates damage. Always. You can minimize it, but you can't ever get rid of it.

Re: Conserve disc space
Thank you for your response. Will I have to reside a copy of Audacity on a seperate external hard drive in order to store about 120 lectures and stereo music as well? I thought I read somewhere in Wiki that I had to keep these in the same Drive/Folders/Directories? I intend to purchase an external hard drive in order to accomplish these Audio tasks because their large sizes/volume (never knew that).

You step from one sinking ice floe to another.
Audacity will not Save sound files and you can't move Audacity Projects. That's pretty powerful stuff and you might want to read it again.
If you have a large collection of performances saved in Audacity Project form, it's only a matter of time before you lose them. They're not sound files. Audacity Projects are Editorial Production Environment Managers and they can be quite large, complicated, confusing, and brittle.
It is strongly urged that you open each lecture Project and Export As WAV. A WAV file is a real, high-quality, stand-alone sound file that you can move anywhere on your machine that it will fit. You can make copies of it onto different media as a backup. You can email one to your mum. All things you can't easily do with an Audacity Project.
