I have 6 mp3 files I would like to put on a CD. They should be playable in all stereos so I guess I would need them in wav format?
I have Windows XP. What is the easiest way to make my CD?
You don't need to do any conversion, you can use CDBurnerXP.
CDBurnerXP is freeware (requires Microsoft .NET framework for versions 3.5 and above).
My favourite little audio burner, handles all important formats, 'understands' EAC's cue sheets (a HUGE plus in MY books) and easily throttles the speed (for better quality, lower writing speeds do indeed have a measurable effect on the quality of the signal burned into a CD-R)
Burrrn is freeware (and easy to make "portable" with Universal Extractor).
if you're looking for a fully-fledged disk burning suite that does much more than just creating audio CDs from mp3, consider InfraRecorder:
InfraRecorder is a CD/DVD burning solution for Microsoft Windows. It offers a wide range of powerful features; all through an easy to use application interface and Windows Explorer integration.
Create custom data, audio and mixed-mode projects and record them to physical discs as well as disc images.
Supports recording to dual-layer DVDs.
Blank (erase) rewritable discs using four different methods.
Record disc images (ISO and BIN/CUE).
Fixate discs (write lead-out information to prevent further data from being added to the disc).
Scan the SCSI/IDE bus for devices and collect information about their capabilities.
Create disc copies, on the fly and using a temporary disc image.
Import session data from multi-session discs and add more sessions to them.
Display disc information.
Save audio and data tracks to files (.wav, .wma, .ogg, .mp3 and .iso).
InfraRecorder is open source freeware, a portable version is available.
Not sure why everyone suggests third-party software, as XP can do this just fine on it's own. Select the files you want on the CD, right-click them, select Send To, then your CD writer. The CD writing wizard will ask you whether you want a data or audio CD.
You probably already have iTunes installed. If so use that instead. Its free and does the job pretty painlessly.
Of course if you don't already have it installed then it would be pointless to install it in which case one of the lighter weight options above would be a better bet.
