DVR to FLAC Converter

DVR to FLAC Converter

A .dvr file is a digital video recorder recording, most often Microsoft's DVR-MS Media Center format that older Windows PCs used to capture live TV. This tool discards the video and pulls the recording's audio track into FLAC, the Free Lossless Audio Codec. Use it to lift a concert, interview, lecture, or program soundtrack out of an aging Media Center archive and into an open, lossless file you can keep, edit, or add to a music library before the format fades out entirely.

This extracts audio only. The MPEG-2 video in the recording is dropped; if you want to keep the whole clip, save it as video with DVR to MP4 instead, or get a small shareable audio file with DVR to MP3.

How to Convert DVR to FLAC

1. Upload Your DVR File: Drag and drop your .dvr or .dvr-ms file onto the page, or click "+ Add Files" to browse. Copy-protected Media Center recordings cannot be processed — only unencrypted files will open.
2. Set the Compression Level: Open Advanced Options and use the "Compression level" slider (1-12). Because FLAC is lossless, a higher level only makes the file smaller and the encode slower — it never changes how the audio sounds. Leave it at the default for a fast encode, or raise it to squeeze the file.
3. Adjust Audio Channel and Sample Rate (Optional): "Audio Channel" and "Audio Sample Rate" both default to "Original", which keeps the recording's native layout and rate — the right choice for a faithful copy. Override them only if you need a specific mono/stereo or sample-rate target. You can also set "Trim" to export just part of the recording.
4. Convert and Download: Click Convert to receive your FLAC file. No sign-up, no watermark.

To shrink an existing lossless library rather than convert from a recording, see the Audio Compressor.

Frequently Asked Questions

Does converting DVR to FLAC improve the audio quality?

No, and this is the key thing to understand. FLAC is lossless, but it can only losslessly preserve whatever it is given. The audio inside a DVR-MS recording is already a lossy broadcast track — MP2, or Dolby Digital AC-3 on HD channels — so the detail those codecs discarded at record time is gone for good. Wrapping that audio in FLAC stops any further loss from this point on, but it cannot rebuild fidelity the original broadcast never stored. You get a clean, lossless archival copy of the recorded audio, not a higher-quality master.

Why is there no bitrate or quality setting like there is for MP3?

Because FLAC does not work that way. Lossy formats such as MP3 throw away audio data to hit a target bitrate, so they expose quality presets. FLAC keeps every sample, so the only knob is the compression level, which trades encode time for a smaller file without ever touching the sound. That is why this converter shows a "Compression level" slider instead of a bitrate or quality preset — there is no quality to trade.

Why won't my recorded TV file convert at all?

Microsoft Media Center marked some broadcasts as copy-protected. When the broadcaster set that flag, the resulting DVR-MS file is encrypted and, per Microsoft's documentation, plays back only on the computer that recorded it — it cannot be re-encoded elsewhere. If your file refuses to process, it is most likely DRM-protected rather than corrupted. Unencrypted recordings extract normally.

My .dvr file is from a CCTV or set-top box, not Windows Media Center — will the audio extract?

It depends on the recorder. Many standalone DVR and CCTV boxes write proprietary .dvr dumps that are really MPEG-2, AC-3, or H.264 in a custom wrapper, and those often extract fine. Others write a raw, headerless stream that only the manufacturer's own player understands, and some security recordings carry no audio track at all. If a non-Media-Center .dvr file will not open, export or "back up" the clip from the recorder's own software to a standard format first, then convert that.

Does the FLAC file keep the original Dolby Digital surround channels?

It keeps whatever channels the recording actually carried, up to FLAC's limit of 8. If the broadcast was 5.1 AC-3 and you leave "Audio Channel" on "Original", FLAC stores those channels losslessly. Note that this is a decode-and-re-wrap, not a passthrough: the AC-3 is decoded to PCM and then FLAC-encoded, so the result is a lossless container around audio that began as a lossy surround mix.

Is FLAC the right choice, or should I use MP3?

Pick FLAC when you want a true archival copy or an editing source and do not mind the larger file — it preserves the recorded audio exactly as delivered. Pick DVR to MP3 when you want a small, universally playable file for a phone or car and a modest, transparent amount of further compression is acceptable. In our testing, the same recorded-TV audio came out several times larger as FLAC than as a 192 kbps MP3, which is the expected trade for keeping every sample.

What happens to my file after the conversion?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion finishes. There is no sign-up, no watermark, and your files are never shared or made public.
