Convert M4P to CDA

Understanding M4P and CDA file formats

M4P is a protected audio file format used by Apple for songs purchased from the iTunes Store. These files are encoded with AAC (Advanced Audio Codec) and are protected by Apple's FairPlay DRM, restricting playback to authorized devices.

CDA stands for Compact Disc Audio track. It is not an actual audio file but a small (44-byte) shortcut file created by Windows to represent audio tracks on a CD. CDA files do not contain audio data; they simply point to the location of the audio on the CD.

Why convert M4P to CDA?

Converting M4P to CDA is typically done to create audio CDs from iTunes-purchased music, allowing playback on standard CD players. Since CDA files are only pointers, the actual process involves burning the audio to a CD in a format compatible with CD players.

How to convert M4P to CDA

Direct conversion from M4P to CDA is not possible due to DRM protection and the nature of CDA files. The process involves two main steps:

1. Remove DRM from M4P files (if necessary): Use a DRM removal tool to convert M4P to an unprotected format like MP3 or WAV.
2. Burn the unprotected audio files to a CD: Use CD burning software to create an audio CD. The software will generate CDA files as part of the burning process.

Recommended software for M4P to CDA conversion

• iTunes (Music app on macOS Catalina and later):
  • Authorize your computer with your Apple ID.
  • Create a playlist with the desired M4P songs.
  • Insert a blank CD.
  • Go to File → Burn Playlist to Disc and select Audio CD as the format.
• Tunefab Apple Music Converter:
  • Removes DRM and converts M4P to MP3/WAV.
  • After conversion, use any CD burning software (e.g., Windows Media Player, Nero) to burn the files to an audio CD.

Important notes

• CDA files are not standalone audio files; they only exist on audio CDs.
• DRM removal may be subject to legal restrictions in your country. Ensure you comply with local laws.
