Convert WTV to AIFF — Free Online Converter

WTV (Windows TV) is the DVR recording container from Microsoft's Windows Media Center, storing broadcast television as MPEG-2 or H.264 video with AC3 or AAC audio alongside EPG metadata (program title, description, channel, ratings, recording time). The NTFS-like internal structure supports multiple streams within a single file. AIFF (Audio Interchange File Format) is Apple's uncompressed audio standard, storing raw PCM samples at full quality — commonly used in professional music production and audio mastering on macOS.

With Windows Media Center removed from Windows 10 and no successor application, WTV files represent a closed chapter of Microsoft's living room strategy. Yet personal archives contain irreplaceable TV recordings — live concerts, sporting events, holiday specials — that deserve preservation in modern, accessible formats.

Converting WTV to AIFF extracts broadcast audio into an uncompressed, lossless format suitable for professional audio work. This is essential when the TV recording contains audio that needs further editing, processing, or mastering — such as concert performances, live music broadcasts, or spoken-word content intended for podcast production.

AIFF files integrate seamlessly with macOS-based audio workflows (Logic Pro, GarageBand, Final Cut Pro) and maintain exact audio fidelity from the decoded broadcast stream. While the files are larger than compressed formats, they serve as perfect masters for subsequent editing and distribution.
