MP3 Files Help

Yes, that's the extention.

But CD's are not stored as wav format, it's just what MS uses as a default uncompressed format. Your normal cd player wouldn't recognise them if they were .wav files as it can only read CDDA. See here regarding the Red book CDDA format. If you used a mac to rip cd's uncompressed it probably wouldn't use .wav as a standard, it would more than likely use the .raw format.

The shorcuts are definitely on the CD, as you can do a file properties on them directly. But like you say that might be a Windows OS interpretation as 44kb seems very large for a Table of Contents(TOC) index file. Let me check...

no...its 44bytes!! yep that is just an index file on the CD that contains the start address of the tune. So you can skip from one track to the next

btw the .cda files contain null (code=0) characters...odd

I think the cue sheet method sounds a lot simpler. Basically, all the files are dumped together with a single cue sheet (*.cue) that accompanies them. The cue sheet contains the following:
Code: 
FILE C:\TRACK1.WAV WAVE
TRACK 01 AUDIO
INDEX 01 00:00:00
FILE C:\TRACK2.WAV WAVE
TRACK 02 AUDIO
INDEX 01 00:00:00
FILE C:\TRACK3.WAV WAVE
TRACK 03 AUDIO
INDEX 01 00:00:00

By using that, the CD player could detemine the start and end times of each track. Mind you, can you use this method on your PC with MP3s. You can rip and entire album as one giant MP3 (or WAV, Ogg, etc), and then have the media player read the cue sheet to display each song seperately and play them. The syntax would be like so:

Code: 
FILE C:\FULLCD.WAV WAVE
TRACK 01 AUDIO
INDEX 01 00:00:00
TRACK 02 AUDIO
INDEX 01 04:31:00
TRACK 03 AUDIO
INDEX 01 08:32:00
TRACK 04 AUDIO
INDEX 01 10:58:00

One file (fullcd.wav) is indexed and the start times of each song are also indexed. The player uses this to detemine the length of each track and divide the WAV file accordingly. The only bonus I can see to using this though, is if you use MP3, a few frames at the start of the track are required for the codec to 'wind up'. Those few frames are silent. If you have songs that pick up where the previous left off (Pink Floyd are a classic example) you'd notice a slight silent gap between track changes. By having the album as one giant MP3, the file has already been 'wound up' and the track changes are seemless.
 
Try this CDDA Extractor BigJames. I have used it before to change .m4a (mp4) files into .mp3 You just drag the file into the convertor window, choose the format you want to convert them to (mp3) and the press go. Its a 30 day trial version.

Then you want to download one of those Wave Editors to crop the bit you want.
Or you can email me the track and I will convert it for you, and I'll even crop out the bit you want :)
 
Cracking - Its worked, Im currently changing the tracks I want over to MP3. Thanks Tacet Blue 👍

Now which program should I use to only record say the middle 30 seconds of the song ? There are so many programs listed, which one have you used ?

Thanks

I'd try this one Its very basic but does the job. It took 4 secs to download!

I tried it quickly, you just open the file you want to crop. Set the start point with the "[" icon the the end with the "]". Then press the red record button...simple :) The output file will be in the C:\Program Files\ECPSoft\MP3-Trimmer\OutFiles by default, you can change the location of the output file by using the settings button (last icon)
 
Brilliant mate, thats worked too. Anyone reading this who is as un-educated as I am in the world of PC's and wants to play with MP3 files etc.... take note of tacet blue's advice here.

Thanks to anyone who replied with advice.
