CDDA Reader 1.8.9.129

When Windows Media Player or another DirectShow-based player refuses to read audio CD tracks directly, the missing component is almost always CDDA Reader - a 568KB filter that exposes CD Digital Audio content to any compatible application as standard wave data.

Why CD Audio Playback Fails

Windows does not include a built-in DirectShow source filter for raw CDDA tracks.

Without one, applications that rely on the DirectShow pipeline simply cannot access the audio data on the disc, even if the drive itself works fine.

No error message explains this clearly, which is why the fix is so easy to miss.

What CDDA Reader Does

CDDA Reader registers itself as a DirectShow source filter and handles the read layer between the CD drive and your media player.

Once installed, apps like Windows Media Player can open and play CD audio tracks as wave files without any additional configuration. It runs entirely in the background.

If your audio setup needs more than basic CD playback - for instance, decoding AC3, DTS, or other compressed streams - AC3 Filter handles those cases.

For a complete DirectShow audio stack in one install, a Codec Pack bundles everything together.

If you're unsure what's missing from your system, the Codec Troubleshooter can identify the gap before you install anything.

You can also convert CD audio to other formats using the Online Audio Converter without installing any software at all.

Install and Forget

CDDA Reader is freeware, weighs 568KB, and needs no interface or settings. Install it, reopen your player, and your CD audio will be accessible immediately.

Compatible with Windows 7, 8, 10, and 11.
