Overview
CDA stands for CD Audio Track. Unlike common audio formats such as MP3, WAV, FLAC, or AAC, a CDA file does not store the sound from a song. It is a small index created by Windows so the system knows where a track begins on an inserted audio CD. This is why files such as Track01.cda are only about 44 bytes even when the song itself lasts several minutes.
A CDA file therefore cannot work independently from the disc it refers to. If you copy Track01.cda from a CD to the desktop, USB drive, phone, or cloud storage, you have copied only the shortcut, not the audio. To keep the music after removing the CD, you need to rip the audio CD and save the tracks as real audio files.
WonderFox Free HD Video Converter Factory does not turn a standalone .cda shortcut into audio. After you rip the CD, however, you can use it to cut, split, merge, and convert the saved audio files to a format that works better on your player or device. It also works for downloading songs/albums/mixtapes/audiobooks from 1000+ popular websites.
To play a CDA track, keep the original audio CD in a connected CD/DVD drive. On Windows 11, the current Media Player app can play audio CDs. Windows Media Player Legacy can also play them, and VLC is another option. On a Mac, the Music app can play audio CDs when an internal or external optical drive is available.
If a copied .cda file on your hard drive refuses to open, changing the default app will not fix it because the file no longer points to accessible audio data. Insert the original disc and play the track from the CD, or rip the disc first using one of the methods below.
Strictly speaking, you do not convert a CDA file itself. You rip the audio CD and encode the real track data as MP3, WAV, FLAC, AAC, or another audio format. This also explains why an online CDA-to-MP3 converter cannot work with a 44-byte CDA shortcut alone: the website does not have the audio from the original disc.
Note: Rip CDs only when you have the right to make a copy. Rules for personal copying vary by country and by the content on the disc.
Method 1. Rip an Audio CD with Media Player on Windows 11
The redesigned Media Player for Windows 11 supports audio CD playback and CD ripping. Microsoft’s published feature announcement lists AAC, WMA, FLAC, and ALAC as supported ripping formats. If you specifically need MP3 and it is not offered in your version of Media Player, use Windows Media Player Legacy in Method 2.
Step 1. Connect an internal or external CD/DVD drive, insert the audio CD, and open Media Player.
Step 2. The Media Player app should automatically recognize the CD and display it on the left-hand menu.
Step 3. Select the audio CD in Media Player and wait for the track list to appear.
Step 4. Open the Rip settings, choose an available output format and quality, then click "Save".
Optional. Open "Edit info" to edit the metadata for each track or click "Update album info online" to fetch the missing media info automatically.
Step 5. Click "Settings" at the lower left corner to choose an output folder, then click Rip CD.
When ripping finishes, open the output folder and play the exported audio without the disc.
Method 2. Rip a CD to MP3 with Windows Media Player Legacy
Windows Media Player Legacy remains useful when you want a straightforward MP3 rip on Windows 10 or 11. On some Windows 11 systems it is an optional feature. If you cannot find it, go to Settings > System > Optional features > View features, search for Windows Media Player Legacy, and add it.
Step 1. Insert the audio CD and open Windows Media Player Legacy.
Step 2. Switch to the Player Library and select the CD drive from the left pane.
Step 3. Click Rip settings. Choose Format to select MP3, WAV, FLAC, or WMA, then choose Audio Quality if needed. You can also open More options to change where ripped music is saved.
Step 4. Clear the check box next to any track you do not want, then click Rip CD. The finished files are saved to your Music folder by default unless you changed the location.
Method 3. Import a CD with iTunes on Windows or Music on Mac
Apple still documents CD importing in iTunes for Windows. On newer Windows PCs, Apple has separated music into the Apple Music app, while iTunes remains available for users who have not moved their music library to the newer Apple apps. On a Mac, the equivalent CD-import feature is built into the Music app.
iTunes on Windows: Open Edit > Preferences > General > Import Settings. Choose MP3 Encoder if you want MP3, or select AAC, AIFF, Apple Lossless, or WAV. Insert the CD, select the tracks you want, and click Import CD.
Music on Mac: Open Music > Settings > Files > Import Settings and choose the encoder you prefer. Insert the audio CD, select it under Devices if necessary, choose the tracks, and click Import CD. Music uses AAC by default, but MP3 is also available in Import Settings.
Q1. Can I convert a CDA file to MP3 online?
Not from a copied CDA file alone. The tiny .cda file contains no music. The original audio CD must be available so a ripping program can read the real track data.
Q2. Why is every CDA file only about 44 bytes?
Because it is only an index that points to a track on the disc. The actual audio data remains on the CD.
Q3. Why does a CDA file play from the CD but not after I copy it?
After it is separated from the disc, the shortcut no longer has access to the audio track it references. Rip the CD to a real audio file instead of copying the .cda item.
Q4. Which format should I choose when ripping a CD?
Choose MP3 for broad compatibility and smaller files, or FLAC/ALAC when you want lossless quality and do not mind larger files. WAV is also lossless but usually takes more space and stores metadata less consistently across apps.
A CDA file is not a music file you can copy and convert by itself. It is only a pointer to an audio track on the original CD. Keep the disc inserted if you only want to play the track. If you want a permanent copy for a phone, media player, backup, or another computer, rip the CD with Media Player, Windows Media Player Legacy, iTunes, or Music on Mac and save the result as a normal audio file.
