Why can't I burn a 242mb wav file to a cd?

[jbilly]

I mixed down and mastered a 242 mb wav file from by tascam dp01fx recorder to the computer and it won't let my burn it to cd. It says the file is to large? I thought cd held 700mb? Any thoughts.....

Make sure that your file contains a standard format 16/44.1 stereo wavfile with no extraneous data. And make sure that you are instructing your CD burner application to burn a standard audio CD and not some other format (assuming that's your intention). An audio CD can actually hold quite a bit more than 700MB - that limit is for data discs. Audio discs have less error correction capabilities, so they can hold something closer to 800MB of data. But it has to be in the right format.

Gilliland is right. That is either a rediculously long song or it is not 16/44.1

I have burned .wav files that take up almost the whole disc no problemo. I would check your software.

An audio CD is not a data CD.

An audio CD holds 74 minutes of 16bit/44.1kHz stereo. No more....

The five CD rec.audio.pro set that I did had 3 discs which ran around the 78 minute mark. 74 minutes is the "suggested" limit, but you can squeeze about 4 more minutes out of them if you try.

don't for get Red Book standards...

The Red Book specifies the physical parameters and properties of the CD, the optical "stylus" parameters, deviations and error rate, modulation system and error correction, and subcode channels and graphics.

It also specifies the form of digital audio encoding (2-channel 16-bit PCM clocked at 44100 Hz). These parameters have become something of a de-facto standard.

Bit rate = 44100 samples/s × 16 bit/sample × 2 channels = 1411.2 kbit/s (more than 10 MB per minute)

On the disc, the data is stored in sectors of 2352 bytes each, read at 75 sectors/s. Onto this is added the overhead of EFM, CIRC, L2 ECC, and so on, but these are not typically exposed to the application reading the disc.

By comparison, the bit rate of a "1x" data CD is defined as 2048 bytes/sector × 75 sectors/s = exactly 150 KiB/s = about 8.8 MB per minute.

not that I understand any of that


My band had a CD pressed a couple of years ago and we were told that we had to provide a master on a 74 minute CD recorded at 1x and the total length had to be under 73 minutes. Perhaps things have changed since then...

Keeping it at under 74 minutes is for the pressing house's protection, against complaints that some older CD players won't read a heavily packed disc. The rec.audio.pro set didn't pose any problems for anybody in reading the 78 minute CD's.

I think they are right about this.... if you are making an "audio cd" then the file size wont matter if it plays more than the allowed number of minutes.

You can prove it by trying to burn an audio cd using 128kb mp3 files. Even though the total sum of the mp3 files all together might only be about 100mb, if the total playing time exceeds 74 minutes, it wont burn the disc.

I'm still trying to figure out of the person was simply trying to burn a data disc. He did not specify which.

 

[soundchaser59]

Had to be an audio cd.......I burn data disc every day with 500 and 600mb files, no problem.
