What Type of Audio Files Can Be Read by Cd Players?

This page provides an overview of how to burn an audio CD.

Audacity does not fire CDs directly but audio files created with Audacity can be used with a CD burning awarding to create an audio CD.

Audio CDs

In that location are ii principal types of CDs that y'all can create with CD called-for software: sound CDs and data CDs.

To ensure that you create a CD that volition play anywhere information technology is of import to choose the option to burn an "Audio CD" or "Music CD" and not a "Data CD". A data CD containing for example MP3 or WAV files will play happily on your computer but is unlikely to play in a standalone CD player or in-motorcar CD player (annotation that some modern CD players will play data CDs). An audio CD will play on any standalone or in-motorcar CD player and in your figurer and in modernistic DVD players.

Audio CDs do not have files or a file organisation like data CDs and other computer storage media, only consist essentially of a stream of bits on the disc in a unmarried spiral "track" with a TOC (Tabular array of Contents) index.

Audio CDs are more often than not express to 74 minutes playing time on a 650 MB disc ("Blood-red Book Standard") or 80 minutes on a 700 MB disc.

When buying blank CDs for burning, it is strongly recommended that you purchase practiced quality CD-Rsouth (that can be burnt only in one case) and non the rewritable CD-RWs.

Brazenness setup

Audio CDs ever contain uncompressed PCM stereo audio at 44,100 Hz sample rate , 16-bit sample format . So to burn an audio CD, export the file(s) y'all want to fire as a 44,100 Hz 16-flake stereo WAV or AIFF file.

To configure Audacity for this:

At the bottom left of the Audacity window, set up the Projection Rate to 44,100 Hz.
Some CD burning software require you to accept a stereo track. If your Project does non already contain a stereo track, click . Information technology does non matter that this track is empty, its purpose is but to make Audacity export your recording as a stereo file. This step is not needed if you are called-for to CD with Apple tree Music/iTunes or Toast.
Click .

It may be possible to use other formats if your CD-called-for software supports them, but they may not requite the all-time quality or they may not be playable on all CD players.

If you feel clicks at the start or terminate in the resulting CD tracks, this may considering your CD burning drive or software does not correct for runway splits fabricated outside CD frame boundaries. To enable splits at CD frames, right-click or use the context key when over any of the three fields in Selection Toolbar, then choose 1 of the choice formats for CDDA frames. This may as well be required if called-for gapless CDs.

Multiple songs

If you are exporting a long Audacity track that contains multiple songs, please run into "Splitting a recording into separate tracks" for how to export multiple files for each of the songs past using labels to identify songs for the Export Multiple command to operate on.

An culling method is to apply Cue Sheets to define individual songs.

Burning software

In order to fire an audio CD you lot will need a CD burning application. Most computers already come up with media histrion software that can burn CDs. For example, you can use Windows Media Role player built into Windows or Music built into Macs. Ensure in either Windows Media Player or Music that you lot select the option for burning a "Music CD" and not a "Data CD" as mentioned to a higher place, unless yous choose Audio CD, the CD will not play on most CD players.

Windows Media Thespian

In Windows Media Role player:

Use the Burn tab
Drag the files you want to burn to CD onto its "Fire list"
Click on "Start burn".

Windows Media Role player 11 will not accept WAV files for burning if they are dragged straight into a fire list without having previously been played in Media Player. You will see a ruby-red symbol and a "length of file cannot be adamant" error. To solve this problem, elevate the file into the Media Player Library or into a playlist, then from there into a fire list. Windows Media Actor 12 does not have this problem.

Also, neither Windows Media Player 11 or 12 can burn AIFF files, so you must export from Audacity every bit WAV.

Apple tree Music/iTunes

In Apple Music/iTunes:

Create a playlist
Drag the files you want to burn down into it
Right-click on the playlist in the left hand panel and click on the "Burn Playlist to Disc" in the dropdown menu
- in iTunes version ix and earlier, click the Burn down Disc push button bottom correct of the window
Select the burner speed, the gap between songs if you are burning multiple files onto the CD
Brand sure "Audio CD" is selected as the "Disc Format"
Click "Fire".

Troubleshooting:

If you receive a "computer non authorized" error, double-click the file in the Apple Music/iTunes playlist and enter the password you utilise to login to Apple Music/iTunes store.
You cannot burn a playlist containing protected M4P files that take been burned more than seven times.
If you receive "Error 4880", burning cannot initialize because of a hardware defect or because the burn speed is too loftier.

Other burning software

You tin also use a standalone Windows burning application like CDBurnerXP, Deep Burner or Nero (or Fire or Toast for Mac) to burn your exported files. Virtually Linux distributions include Brasero or K3B for CD burning. When using standalone burning applications, open the files from within that software, do non drag and drop them from your file manager. One time over again practise not forget to select the setting to fire an "Audio CD" or "Music CD" every bit explained above.

Mutual Pitfalls

Incorrect sample charge per unit: Nearly CD burning software expects all files to be at 44100 Hz.
Unsupported formats: Some CD called-for software does not support compressed formats such every bit MP3 , OGG , or M4A/AAC.

Metadata and CD-Text

Even if you use Audacity'due south Metadata Tags editor to add metadata such every bit Title, Creative person and Genre to your exported WAV files, that metadata does non go automatically burned to the CD. You tin set Apple tree Music/iTunes and another called-for applications (but non Windows Media Player) to burn metadata to each track as separate CD-Text. Providing your CD burner supports CD-Text, a standalone CD histrion that supports CD-Text will then be able to brandish each rails's metadata.

You tin also use a Cue Sail to add CD-Text in called-for applications that support Cue Sheets.

Gapless burning

By default, many CD burning applications add a two-second gap betwixt CD tracks as office of the standard for sound CDs. So be aware of CD track gaps when placing labels between anthology tracks for Export Multiple and consider deleting excess silences between tracks.

Yet most CD called-for applications have an option to burn the CD with no gaps between tracks. This is useful for recordings such as live concerts, allowing the CD to play continuously if the player supports gapless playback while nonetheless permitting skipping to individual CD tracks. If called-for a gapless CD, you volition demand to place the Brazenness labels exactly where you intend the burner to marker the track splits. Some CD burning applications (for example, older versions of Windows Media Actor) have no option to burn without gaps. Gapless called-for is as well only available if the optical drive supports Disc-At-Once (DAO).

Additionally, make sure yous practise non export MP3 files for burning to your gapless CD, even if you are called-for a "data CD", because MP3s have inherent silence padding due to a restriction of the MP3 format.

Note you may still hear the nearly momentary gaps between tracks even on DAO burned CDs, unless the CD player supports true gapless playback. Many CD players practise not back up gapless playback properly because the hardware but does not buffer the sound data properly. Nonetheless quite a few figurer-based media players can use DSP furnishings when playing back audio to give proper gapless playback, fifty-fifty of CDs non burned with DAO. An example of such a player is Apple tree'southward iTunes.

Cue Sheets

An culling solution is to not separate the track upward at all in Audacity. The all-time fashion to get obviously gapless playback of a live concert recording or alive album is to burn down every bit one WAV file with with DAO and a "cue sheet" that marks the starting times of each CD track. Cue sheets can be created every bit simple patently text files.

Each runway in a Cue Sheet is of this format:

Track (number) Sound
TITLE "(proper name)"
PERFORMER "(name)"
Index 01 (start time) in the format minutes:seconds:frames with the beginning track ever being 00:00:00

Audacity cannot currently consign Cue Sheets merely it is possible to use the command to export a text file representing the label positions, so on Windows and Linux use label2cue to convert the minutes and seconds data in the text file to minutes, seconds and frames data laid out in cue canvas format.

You can read more almost cue sheets on Wikipedia hither.

Burning longer recordings to disc

As stated above sound CDs are generally limited to either 74 or 80 minutes, notwithstanding it is sometimes possible to achive longer times by using Overburning. Alternatively, for longer recordings, you may exist able to use data discs provided your role player will support and play these. (A data CD volition not normally play on older standalone CD players. It will play on computers, most DVD players and in MP3 CD players).

Data CDs and Data DVDs

For burning really long files to optical media, you must burn either a data CD or a data DVD which can contain a set of WAV, MP3 or other audio format files.

For instance, burning MP3 files to a 700 MB data CD (sometimes called an "MP3 CD"), and using Audacity's default 128 kbps MP3 export bit charge per unit gives over xi.5 hours playing fourth dimension. But if 64 kbps MP3 scrap rate was chosen (either in "MP3 Export Setup" in the File Formats tab of Preferences, or Options at fourth dimension of export) near 23 hours of audio would fit on the CD. Note that the penalty of reducing the fleck rate would be reduced sound quality (especially so for music but less so for speech communication).

A single layer 4.7 GB data DVD can accommodate near eighty hours of 128 kbps MP3 audio, though some older DVD players will not play DVD information discs, or only those containing sure sound or video formats.

A data CD will non normally play on older standalone CD players. It will play on computers, most DVD players and in MP3 CD players.

Overburning

You lot tin also get increased playing fourth dimension by using overburning, though this is non recommended as it will produce a non-standard CD which may non play on all CD players.

If you need more playing time than the normal 74 or 78 minutes (for instance, to endeavor and accommodate a C90 cassette or two LPs onto one CD) some CD burners will let y'all "overburn" into the blank CD space so as to extend the playing time past a farther few minutes, so giving you lot the possibility of up to 80 minutes playing time on a 650 MB disc or upward 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 light amplification by stimulated emission of radiation off.

It is also theoretically possible to overburn using "90 minute" (790 MB) or "99 minute" (870 MB) CD-R discs. Notwithstanding there is no guarantee whatsoever that your CD burner will accept such CD-R discs, or that your CD player volition play annihilation other than a Red Book Standard 650 MB disc burned with 74 minutes of sound.
