These are the audio tracks in .WAV format, which any media player should be able to play. Alternatively you could transcode them into FLAC (lossless compression), OGG format (lossy compression), or some other format to save some disk space.

and it also produced a file simply with the title of the audio cd, and without extensions and it is 803066400 bytes large. Running $ file 'Into The Unknown' Into The Unknown: data

The file is quite larger than the 704MB max (with overburn) that a CD can hold. This file is 100MB larger than that.

Larger than a data CD, not than an audio CD. Audio CDs are stored in sectors of 2,352 bytes, where as data CDs put 2,048 bytes plus some checksum data into the same sector space. K3B has generated a raw dump of the CD including the checksum data, rather than stripping it out.

So, how can I use this file? I was hoping it would be in

a format that could be used by any of the plethora of media players in linux. mplayer failed to open it.

I'd say your best path would be to delete it, and then transcode the .WAV files into your audio format of choice.

Thanx Andy. I do know what wav files are. I was hoping to delete them and use just the one file which krb says is the image. I was under the impression it would produce a .img file. But I was disappointed. Apparently becase an audio CD is made of multiple tracks, once cannot create a .img or a .iso of it.

Try this dd if=/dev/sr0 of=cdimage.iso

Uncompressed audio files. They're a sound file (as are MP3s, OGGs, and various other audio files). One might say that they're a Windows format, but I seem to recall that it's a sound blaster thing (a brand of sound card, from donkey's years ago).

Anyway, most players can play wave files, directly. But they are rather large files. As a prior poster has mentioned, you can encode them into another format, to reduce their size. As an added benefit, most of the compressed audio formats (FLAC, OGG, MP3, et cetera), also allow you to insert details about the track (track title, performer's name, et cetera), making it easier to find what you want in your sound player. The disadvantage of most of the compressed formats is loss of audio quality. Flac isn't a lossy compressor, you can get the original data back, exactly. Ogg and MP3 are lossy compressors, some data is lost, but they make much smaller files. I find that Ogg files sound much better, most MP3s have horrible compression artifacts unless they're compressed at very high bit rates (well above 256 kbits/sec).

I was hoping to delete them and use just the one file which krb says is the image.

While possible, it's probably more convenient to keep the audio tracks as separate files, unless you really do want to play albums in one go. Not to mention that some audio players seem to struggle when handling such huge files as a whole disc in one go.

You can indeed make an image of an audio CD, although it's not an ISO9660 image as there's no filesystem as such on an audio CD. What you have instead is something known as a "TOC", or "Table of Contents" file which is written out as ASCII text. I suspect K3B has created a raw image for you, but either not written out the TOC or you've not understood its significance.

I can see where you are trying to go, but I don't think you're going to find a solution that's very well supported by media players. Most of us create a directory for each CD then put the transcoded audio files, plus any cover art images, playlists, etc. in there.

Right. I saw several blogs saying pretty much the same thing.
