WTV to AIFF Converter

How to Convert WTV to AIFF Online

1. Upload Your WTV File: Drag and drop, or click "+ Add Files" to select one or more .wtv recordings from your computer. Batch is supported, so you can queue an entire season of recorded TV in one pass.
2. Pick Audio Codec and Quality Preset: The default is PCM 16-bit big-endian (pcm_s16be) — the canonical AIFF payload. Step up to PCM 24-bit (pcm_s24le written into AIFF-C) for studio masters, or PCM 32-bit float for headroom during further processing. Quality presets range from Lowest to Highest, mapping to internal bitrate and sample-rate combinations.
3. Set Sample Rate, Channel and Trim (Optional): Audio Sample Rate defaults to "Original" (typically 48 kHz from broadcast WTV); switch to 44.1 kHz for CD-compatible masters, or 96 kHz for upsampled archival. Audio Channel can stay at "Original" or be forced to Stereo or Mono. Use Trim with HH:MM:SS.ms inputs to drop the pre-roll, commercial breaks, or post-show padding common in DVR recordings.
4. Convert and Download: Click Convert. Conversion runs in your browser session — no sign-up, no watermark, no upload to a third-party cloud. Each output file streams down as a .aiff (or .aifc for non-PCM payloads).

Why Convert WTV to AIFF?

WTV is Microsoft's container for Windows Media Center recordings, introduced with the Windows Media Center TV Pack 2008 for Vista and carried through Windows 7. Microsoft dropped Media Center from Windows 8 in 2012 and confirmed in May 2015 that Windows 10 would ship without it, which left a generation of broadcast captures — concerts, talk shows, sports calls, news archives — stranded in a container Apple's audio toolchain never spoke. AIFF, released by Apple on 21 January 1988, is the native lossless wrapper for PCM big-endian audio across macOS, Logic Pro, GarageBand, and Pro Tools, so extracting WTV's audio track into AIFF is the cleanest path from a Windows DVR archive to an Apple-side editorial workflow.

• Pro Tools and Logic Pro sessions — AIFF imports as a lossless native file, no transcode on session open. Drop the converted track straight onto a stereo audio track for editing, EQ, or stem creation.
• Podcast and radio editorial — record-and-rip workflows that pull broadcast audio off a Windows Media Center capture card hand off cleanly to a Mac editor when delivered as AIFF rather than MP2-in-WTV.
• Music archival and restoration — uncompressed PCM beats re-encoding broadcast MP2 audio into another lossy codec. A 24-bit AIFF at 48 kHz preserves whatever fidelity the original AC-3 or MPEG-1 Layer II broadcast carried.
• Audio-bed extraction for video re-edits — pull the dialogue/music track out of a WTV recording, edit in Logic, then re-marry to a re-encoded video. See WTV to MP4 for the video-side path.
• CD authoring and red-book mastering — convert at 44.1 kHz/16-bit stereo and you have a track ready to drop into a CD-burning app or DDP project.
• Migrating off Windows Media Center — Media Center has been unsupported for over a decade; converting the audio out of WTV before the playback chain breaks entirely is reasonable archival hygiene.

Frequently Asked Questions

Why does my WTV file fail to play even though Windows recorded it?

Windows Media Center, which created .wtv files, was dropped from Windows 8 in 2012 and removed entirely from Windows 10 in 2015. Newer Windows installs have no native WTV decoder. VLC reads most non-DRM WTV files, but DRM-flagged broadcasts (common on cable channels in the US) refuse to convert — they were encrypted to the recording machine. If conversion fails with a "no audio track" or "encrypted" error, the source recording carries broadcast DRM and cannot be transcoded by any third-party tool.

Will AIFF give me better audio than the original WTV broadcast?

No — and that's not the point. WTV audio is already lossy (MPEG-1 Layer II or AC-3 from the broadcast feed). Converting to AIFF preserves whatever fidelity the broadcast carried; it does not invent detail. The reason to choose AIFF is workflow compatibility (lossless PCM into macOS DAWs) and the absence of any further generation loss during editing, not a quality improvement over the source.

Should I pick 16-bit or 24-bit AIFF for converted broadcast audio?

For listening, archival, or CD authoring, 16-bit at 44.1 kHz is fine and matches Red Book CD spec — file size lands near 10 MB per stereo minute. For DAW work where you plan to apply EQ, compression, or noise reduction, 24-bit gives ~144 dB theoretical dynamic range versus 96 dB at 16-bit, which means fewer rounding artifacts after processing. There is no benefit to 32-bit float for a static broadcast capture unless your subsequent processing chain explicitly wants the headroom.

Why is my AIFF much larger than the WTV file?

WTV stores audio in lossy MPEG-1 Layer II or AC-3 at roughly 192-384 kbps, while AIFF stores uncompressed PCM at ~1,411 kbps for 16-bit/44.1 kHz stereo (and ~2,304 kbps for 24-bit/48 kHz). A one-hour broadcast audio track that was ~150 MB inside the WTV container becomes roughly 600 MB as 16-bit AIFF, or close to 1 GB at 24-bit. That is the cost of lossless wrapping — there is no way to make AIFF smaller without switching to a lossless-compressed format like FLAC or ALAC.

Can I trim out commercials before converting?

Yes. The Trim controls accept start and end timestamps in HH:MM:SS.ms format, so you can convert just the show body and skip the ads. For more granular multi-region cutting (e.g., several ad breaks in the middle of a recording), convert the full file once to AIFF, then run it through Audio Cutter where you can drop multiple segments with waveform-level precision.

Does the converter handle multi-channel (5.1) audio from WTV?

WTV recordings that captured a Dolby AC-3 5.1 broadcast can have a 6-channel audio track. AIFF supports multichannel PCM, but most editorial workflows downmix to stereo at this stage. Leaving Audio Channel at "Original" preserves the channel count; setting it to "Stereo" applies a standard Lt/Rt downmix; "Mono" sums to a single channel. If you need a true 5.1 master, choose "Original" and verify the output in a multichannel-aware player or DAW.

What's the difference between AIFF and AIFC, and which will I get?

AIFF is the original 1988 spec — uncompressed big-endian PCM only. AIFF-C (extension .aifc) is Apple's 1991 extension that allows the same container to hold compressed codecs or non-big-endian PCM. If you pick the default 16-bit big-endian, you receive a strict .aiff. If you pick 24-bit or 32-bit (which are stored little-endian), the file is technically AIFF-C and will be saved as .aifc. Both open in Logic, Pro Tools, GarageBand, QuickTime, and Audacity without issue.

Will AIFF play on Windows?

Yes, with caveats. Windows Media Player has supported AIFF playback since Windows 7. Modern Windows 10/11 plays AIFF via the built-in Media Player and Groove. If you need broadest Windows compatibility outside the Apple ecosystem and don't need AIFF specifically, WTV to WAV gives you the equivalent uncompressed PCM in WAV — same fidelity, native to Windows. For lossy-but-portable, WTV to MP3 is the smaller option.

Is the conversion lossless from WTV's audio track to AIFF?

The transcode from WTV's lossy audio (MPEG-1 Layer II or AC-3) into AIFF PCM is a one-time decode plus a lossless re-wrap. No additional lossy encoding happens, so the output is bit-for-bit identical to what a high-quality decoder would produce from the source — but you cannot recover the audio information that was already discarded by the broadcast encoder. For onward editing in a DAW, this is the right behavior: stay lossless from this point forward.
