You will probably tell from this message that I have, probably, a little too much time on my hands.
I'm waiting for my girlfriend to go into labour. Again. So, in my moment of distraction I had a flash of inspiration.
I'll join up to Club CD Freaks and ask them all a question which has been bugging my since I got my nice new dual layer DVD writer.
Ok. Enough preamble and onto the question which is at the heart of my confusion.
Can I take audio data from a CD and put it onto a DVD so that it will play in an normal DVD player?
Now, before you all start laughing, here is the idea I have and some supporting and probably wrong mathematics to go with it.
A CD can hold upto 80 minutes of audio (maybe not 80 minutes exactly, but close to, and I know there are 90-99 minute CDRs available, but I am ignoring these for the time being as I don't want to confuse myself even more!).
When I use Audio Catalyst, I can compress the ripped data to around 1/12th of the original size.
So, equation number 1.
1 AudioCD = 12 MP3CDs
Now lets look at DVDs.
DVDs are sold as holding 4.7GBs of data. Now I know this is not the 4.7GBs the rest of us use, but 4.7 thousand million (4,700,000,000). I think. For the sake of argument, I'm going to use the same rule for a CD capacity - 700,000,000 bytes.
So, the second equation of the day is to determine how many CDs would fit onto a DVD.
1DVD = 4,700,000,000
1CD = 700,000,000
1DVD = 4,700,000,000 / 700,000,000 CDs
1DVD = 6.71CDs
1DVD = 6.71 * 80mins
1DVD = 537.14 mins
1DVD = 8.95 hours of audio music
So far so good, a DVD holds more than a CD. I'm sure you are all saying "I could have told you that!!!", and I am sure you are right on that.
Ok, equation number 3. How many MP3 CDs could you get onto a DVD?
1DVD = 6.71CDs * 12
1DVD = 80.52MP3CDs
That seems like a lot! But, and this is where the fun REALLY starts, an if an MP3CD is approximately 1/12th the size of a normal CD, does it follow that ...
1DVD = 80.52MP3CDs * 80minutes
1DVD = 6445.71 minutes of MP3 music
1DVD = 107.43 hours of MP3 music
1DVD = 4.48 days of MP3 music
That is nearly FOUR AND A HALF DAYS OF MP3 MUSIC ON A SINGLE DVD!!!!!!!!!!!!!!!!!!!!!!!!
That is a SINGLE LAYER DVD!!!!!!!
Are we ready for this?
A dual layer DVD holds 8.5GB of data (and I'll use the 8,500,000,000 bytes).
1DLDVD = 8,500,000,000
1CD = 700,000,000
1DLDVD = 8,500,000,000 / 700,000,000 CDs
1DLDVD = 12.14CDs
1DLDVD = 12.14 * 80mins
1DLDVD = 971.43 mins
1DLDVD = 16.19 hours of audio music
1DLDVD = 12.14CDs * 12
1DLDVD = 145.71MP3CDs
1DLDVD = 145.71 * 80 minutes
1DLDVD = 11657.14 minutes of MP3 music
1DLDVD = 194.23 hours of MP3 music
1DLDVD = 8.10 days of MP3 music
I'll repeat in capital letters.
ONE DUAL LAYER DVD COULD HOLD OVER EIGHT DAYS OF MUSIC IN MP3 FORMAT
Am I crazy? Have I missed the boat? Is my processor short of a register or two?
I don't think so.
Lets say there is an application which could construct DVD images for buring from CDs. Imagine a program that worked in the following way.
1 - You put a CD in to the drive.
2 - It is read and ripped.
3 - Cover image, track listing, lyrics and other text stuff was collected over the internet.
4 - A library is built from this information.
5 - You can repeat the steps 1 to 4 as often as you like.
6 - You can manually add existing files and images and text.
7 - You decide to build a DVD of your favourite music.
8 - You pick the tracks.
9 - Covers and lyrics are automatically added to the DVD.
10 - It tells you how many days of music you have left to fill on the DVD.
11 - You say BURN and a little while later you have a fully working, interactive menus and all, DVD of your favourite music.
I'd say that is a GOOD program!
But, does one already exist?
If you have found this ramble interesting and you can contribute PLEASE do so!
