Convert WTV to FLAC — Free Online Converter

WTV (Windows TV) recordings from Windows Media Center store broadcast television with MPEG-2 or H.264 video and AC3 (Dolby Digital) or AAC audio, plus EPG metadata including the program title, episode description, channel name, and recording time. The format was Microsoft's replacement for DVR-MS, using an NTFS-like internal structure for efficient real-time recording. FLAC (Free Lossless Audio Codec) is the open-source standard for lossless audio compression, achieving 50-60% compression while preserving bit-perfect audio quality.

With Windows Media Center defunct since Windows 10, WTV files are stranded in personal archives. For recordings where the audio content is the primary value — live concerts, musical performances, radio simulcasts, classical music broadcasts — extracting to FLAC preserves every bit of the original broadcast audio.

Extracting audio from WTV to FLAC captures the full decoded broadcast audio quality in an open, widely supported lossless format. Unlike lossy extraction to MP3 or AAC, FLAC introduces zero additional quality loss beyond what the original broadcast compression (AC3/AAC) already imposed. This makes FLAC ideal for archiving audio from recordings that may be irreplaceable.

FLAC is supported by virtually every media player except Apple's native apps (which prefer ALAC). It integrates with music servers, audiophile playback chains, and audio editing tools, making it the go-to choice for preserving broadcast audio outside the Apple ecosystem.
