HOW MAKE MUSIC HQ SOUND

There are two main types of CD that you can create with CD burning software - an "audio CD" and a "data CD". An audio CD (officially "Compact Disc Digital Audio" or CDDA, or Red Book audio) will play on any standalone CD player, as well as as in your computer and in DVD players. A data CD (sometimes called an MP3 CD where the data it contains are MP3 files) will not normally play on standalone CD players. It will play on computers, most DVD players and in MP3 CD players. So if you want to play your CD on a standalone player, or give it to others and be sure they'll be able to play it, you'll need to burn an audio CD.

When buying blank CDs for recording/burning, it is strongly recommended that you purchase CD-Rs and not the re-writeable CD-RWs.

Audio CDs

Audio CDs always contain high quality uncompressed PCM stereo data at 44 100 Hz sample rate, 16 bit resolution. So if you want to burn an audio CD, you should always export the file you want to burn as a 44 100 Hz 16 bit stereo WAV or AIFF file. To configure Audacity to do this:

At the bottom left of the Audacity window, set the Project Rate to 44 100 Hz.
If you are using a 1.2.x version of Audacity, go to the File Formats tab of Preferences, and in the "Uncompressed Export Format" dropdown, choose WAV (Microsoft 16-bit PCM) or AIFF (Apple/SGI 16-bit PCM).
If your Project does not already contain a stereo track, click Project > New Stereo Track (or in Audacity 1.3.3 or later, Tracks > Add New > Stereo Track). It does not matter that this track is empty, its purpose is just to make Audacity export your recording as a stereo file. This step is not needed if you are burning to CD with iTunes.
Click File > Export as WAV or File > Export as AIFF. If using 1.3.3 or later, click File > Export and choose "WAV, AIFF and other uncompressed types" in the "Save as type" box, then click the "Options" button and choose "WAV (Microsoft 16 bit PCM)" or "AIFF (Apple/SGI 16 bit PCM)".

When you burn the CD, be sure to tell the burning software to burn an "audio CD" or "music CD" (not a "data CD" or MP3 CD").
Always use a high quality CD-R disc. Some standalone CD players may refuse to play CD-RW discs properly.

Because audio CDs must always contain uncompressed 44 100 Hz 16 bit stereo audio, they are necessarily limited on a 650 MB ("Red Book Standard") or 700 MB audio CD to 74 - 80 minutes playing time respectively. If you need more playing time (e.g. to try and accommodate a C90 cassette or two LPs onto one CD), some CD burners will let you "overburn" into the blank CD space so as to extend the playing time by a further few minutes, so giving you the possibility of up to 80 minutes' playing time on a 650 MB disc or up to 86 minutes on a 700 MB disc. Overburning (if your burning software and burner supports it) is always done using Disc at Once (DAO) mode in which the tracks are burnt continuously without turning the laser off. It is also theoretically possible to overburn using "90 minute" (790 MB) or "99 minute" (870 MB) CD-R discs. However there is no guarantee whatsoever that your CD burner will accept such CD-R discs, or that your CD player will play anything other than a Red Book Standard 650 MB disc burned with 74 minutes of audio.
