Convert WTV to ALAC — Free Online Converter

WTV (Windows TV) files were created by Windows Media Center's TV tuner recording feature, capturing over-the-air and cable television broadcasts with MPEG-2 or H.264 video, AC3 or AAC audio, and embedded EPG metadata including program titles, descriptions, channel information, and content ratings. The format's NTFS-like container structure was engineered for real-time recording from TV tuner hardware. ALAC (Apple Lossless Audio Codec) is Apple's lossless compression format, reducing audio file sizes by 40-60% compared to raw PCM while preserving bit-perfect quality.

Windows Media Center shipped with Windows Vista through Windows 8.1, and was available as an add-on for Windows 10 before being fully discontinued. The millions of WTV recordings created during this era now sit in personal archives, increasingly difficult to access as Windows Media Center fades from supported platforms.

Extracting audio from WTV recordings to ALAC produces losslessly compressed files that play natively on Apple devices — iPhone, iPad, Mac, Apple TV, and HomePod. This is the ideal path for users migrating their media libraries to the Apple ecosystem, particularly for recordings containing music, concerts, or high-quality audio worth preserving at full fidelity.

ALAC offers approximately 50% compression over uncompressed formats like AIFF or WAV, making it a storage-efficient choice for archiving broadcast audio. Apple Music and iTunes handle ALAC natively, allowing extracted TV audio to integrate seamlessly into existing music libraries.
