WTV (Windows TV) is Microsoft's DVR recording format from Windows Media Center, containing broadcast television with MPEG-2 or H.264 video, AC3 or AAC audio, and rich EPG metadata including program title, description, channel, and recording time. MP3 (MPEG-1 Audio Layer 3) is the universal lossy audio format that revolutionized digital music, supported by every device, operating system, and audio player in existence.
Extracting MP3 from WTV strips away the video component entirely, preserving only the broadcast audio track. This conversion is valuable for TV content where the audio carries the primary value — concerts, talk shows, interviews, radio simulcasts, music performances, and educational lectures where visual content is secondary to what is being said or played.
MP3 is the most universally supported audio format on the planet. Every phone, computer, car stereo, Bluetooth speaker, smart speaker, and media player plays MP3 without exception. Converting WTV audio to MP3 makes broadcast content listenable everywhere — no special software, no compatibility concerns, no format negotiations.
For talk shows, news broadcasts, podcasts recorded from TV, and music performances, the audio track is often all that matters. Extracting to MP3 reduces multi-gigabyte WTV recordings to compact audio files of 30-60 MB per hour, making them practical for phone storage, playlist creation, and podcast-style consumption during commutes.
FFmpeg demuxes the WTV container, discards the video stream entirely, and decodes the audio track — AC3 (Dolby Digital) at 192-384 kbps or AAC at 128-256 kbps. The decoded PCM audio is re-encoded to MP3 using the LAME encoder at the specified bitrate (128-320 kbps) or VBR quality setting. Multi-channel 5.1 AC3 is downmixed to stereo. EPG metadata is discarded, though ID3v2 tags can be added to the MP3 output for title, artist, and album information.
MP3 at 192 kbps is perceptually transparent for broadcast audio content — most listeners cannot distinguish it from the AC3 or AAC source. At 128 kbps, MP3 is adequate for speech (talk shows, news) but noticeably compressed for music. At 320 kbps, MP3 preserves the full quality of the broadcast audio with minimal artifacts. File sizes are approximately 15 MB per hour at 128 kbps and 35 MB per hour at 320 kbps.
