How do I extract the audio from a WebM file as M4R?
+
Upload the WebM file and we demux the audio track, then transcode to M4R. There is no second video pass and no quality loss beyond the M4R codec itself.
What audio bitrate does the M4R file use?
+
Default M4R 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 WebM to M4R?
+
If the M4R format is lossless (WAV, FLAC), you keep every sample exactly. If M4R is lossy (MP3, AAC, OGG), the M4R 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 M4R keep the original sample rate?
+
By default yes — a 48 kHz audio track in WebM becomes 48 kHz in M4R. 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 WebM files to M4R in one batch?
+
Yes — drop a folder of WebM 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 M4R file be tagged with title / artist / album?
+
If the WebM file has chapter or stream metadata, we copy artist / title / album fields into the M4R container. Otherwise the M4R file is untagged — use a tag editor (Mp3tag, Picard) post-export if you need richer tags.
How long does extracting M4R from a WebM file take?
+
Audio extraction is much faster than video re-encoding — typically 5-15% of the source duration. A 1-hour WebM → M4R finishes in 3-9 minutes on the standard pipeline.
Can I extract just a section of the WebM audio as M4R?
+
Not in this tool — extract the full audio as M4R 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 WebM 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 M4R file have silent gaps?
+
Silent gaps usually mean the WebM 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 M4R container if M4R supports it.
Can the M4R extraction be stereo / mono / 5.1?
+
Channel layout is preserved from WebM by default — a 5.1 WebM produces a 5.1 M4R 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 M4R 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 M4R codec most likely to play on your target.
