MKV à FLAC FAQ sur la transformation

How do I extract the audio from a MKV file as FLAC?

Upload the MKV file and we demux the audio track, then transcode to FLAC. There is no second video pass and no quality loss beyond the FLAC codec itself.

What audio bitrate does the FLAC file use?

Default FLAC bitrate is 192 kbps (transparent for music). You can override to 320 kbps (audiophile) or 96-128 kbps (voice / podcast / smaller file). The choice is exposed in the advanced options.

Will I lose audio quality going from MKV to FLAC?

If the FLAC format is lossless (WAV, FLAC), you keep every sample exactly. If FLAC is lossy (MP3, AAC, OGG), the FLAC codec recompresses — quality depends on the bitrate and source audio. We default to 192 kbps which is transparent for almost all content.

Does the extracted FLAC keep the original sample rate?

By default yes — a 48 kHz audio track in MKV becomes 48 kHz in FLAC. If you need 44.1 kHz (CD-quality) for compatibility with older players, the advanced options include a sample-rate dropdown.

Can I extract audio from multiple MKV files to FLAC in one batch?

Yes — drop a folder of MKV files in and we extract audio in parallel. Premium users get more parallel workers; on a 50-file batch this is the difference between 90 seconds and 8 minutes.

Will the FLAC file be tagged with title / artist / album?

If the MKV file has chapter or stream metadata, we copy artist / title / album fields into the FLAC container. Otherwise the FLAC file is untagged — use a tag editor (Mp3tag, Picard) post-export if you need richer tags.

How long does extracting FLAC from a MKV file take?

Audio extraction is much faster than video re-encoding — typically 5-15% of the source duration. A 1-hour MKV → FLAC finishes in 3-9 minutes on the standard pipeline.

Can I extract just a section of the MKV audio as FLAC?

Not in this tool — extract the full audio as FLAC here, then use /audio-trim/ or /audio-cutter/ to clip the section. The two-step path is usually faster than a combined operation.

Is my MKV file private during audio extraction?

Yes — same privacy model as every conversion: isolated workers, automatic deletion within minutes, no human review of content. See /privacy/.

Why does my FLAC file have silent gaps?

Silent gaps usually mean the MKV file had a multi-track audio layout and we picked the wrong stream. Use the advanced "audio stream" option to explicitly pick stream 0, 1, etc., or re-mux all streams to a multi-track FLAC container if FLAC supports it.

Can the FLAC extraction be stereo / mono / 5.1?

Channel layout is preserved from MKV by default — a 5.1 MKV produces a 5.1 FLAC where the codec supports it (AAC, FLAC, OGG). You can force stereo or mono via the channel-downmix option, useful for podcast workflow.

Does the extracted FLAC play on iPhone / Android / car stereo?

MP3 plays everywhere. AAC / M4A plays on Apple and most Android. OGG / Opus needs a recent player on iOS. The advanced options expose a "device" preset that picks the FLAC codec most likely to play on your target.

MKV

Le format MKV (Matroska) peut contenir un nombre illimité de pistes vidéo, audio et de sous-titres dans un seul fichier, ce qui est idéal pour les films.
