Hours of audio on a CD? Possible?

[sdsumike619]

I have this audio that is 3 hours long, at "CD Quality" the wav file is over a gigabyte. So I tried encoding the wav at a much lower sample rate (16,000) and bit depth (8 bit) and got the wav file down to under 400mb - which I thought would fit on the CD because a CD can hold 700mb.

Yet when I go to burn in Nero, it says that it's too small, and in the burn dialog shows the size of the burn to be 1800mb. Why does it do this if the physical size of the wav files are small enough to fit on the CD?

Hopefully I worded that well where you can understand it.. Basically, I thought it was possible to get a lot more MINUTES of audio on the CD (at a much lower rate) as long as the filesize of the wav "fits" a standard CD-R...

Thanks in advance for an explanation =0

Are you trying to burn it is a audio CD?

[lordsmurf]

A CD is fixed on all settings. No.

CD Audio is 74 or 80min

Wma or Mp3 will work but the player needs to support those formats.
Check supported bitrates of the player before you encode the Wma or Mp3.

yes i just wanted to put it on a regular CD-R
The part I don't get is if the wav file that i'm putting on there is in the 400mb range, why doesn't it fit if a CD can hold 700mb ?

The only way to achieve your objective is to create a mp3 disc with software like Nero.

Or put your (modified) file on the CD as data. It won't play in a player like that however.

The reason this is a NO-GO is because nero wants to recode your file to STANDARD CD SPECS!

No STANDARD CD player will play that file. As suggested, burn as a data disc and your computer can deal with it.

Some cheap dvd players will play almost anything that will fit in the slot.
Maybe that cd spec file on a DVD will fly?
Let us know what you end up doing?

well thanks for the input, too bad there isn't some way to TRICK it into working?? i wanted to play it in a portable CD player to listen to while i'm at the gym,,, is there a software program that WON'T attepmt to reencode it to the CD spec? or does a CD HAVE to be 128k, 44100khz to work ?

Audio CD is 44.1k of 16 bit stereo samples per second only. You can reencode it to anything you choose on the computer but it won't play back on your portable CD player. If you want to use higher compressed format such as MP3, WMA, etc. you have to have a player capable of reading these compressed formats. Why not just go get a cheap portable mp3 player?

[sdsumike619]

just wanted to see if it was possible to do as I have a CD player and a lot of blank CDs haha, but yes, I will buy an mp3 player soon,,, thanks

at the gym

you gonna work out for 3 hours

[sdsumike619]

after sittin on a computer all day, you bet!!

[psx_pirate]

There is one simple solution to this .... split the file and burn it to 2 cd-r's (as audio cd's) ... surely its not a major problem to change a disk while you are at the gym

[psx_pirate]

Actually as you have 3+ hours of audio it may need to be split over 3 disks .... still no major hardship changing disks tho surely?

[sdsumike619]

yeah yeah I know, just wanted to see if it was possible to get it all onto one CD, but now i understand that it's minutes, not filesize that matters and that a CD has to have certain sample rate, etc.. Thanks all
