How do I extract the audio from a WebM file as AMR?
+
Upload the WebM file and we demux the audio track, then transcode it to AMR. There is no second video pass and no quality loss beyond what the AMR codec itself introduces.
What audio bitrate does the AMR file use?
+
Default AMR 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 before extraction.
Will I lose audio quality going from WebM to AMR?
+
If AMR is lossless (WAV, FLAC), every sample is preserved exactly. If AMR is lossy (MP3, AAC, OGG, Opus), the AMR codec recompresses — at 192 kbps this is transparent for almost all content. Recovering quality that was already gone in the WebM source is impossible.
Does the extracted AMR keep the original sample rate?
+
By default yes — a 48 kHz audio track in WebM becomes 48 kHz in AMR. If you need 44.1 kHz (CD-quality) for compatibility with older players, the advanced options expose a sample-rate dropdown that resamples with a high-quality filter.
Can I extract audio from multiple WebM files to AMR in one batch?
+
Yes — drop a folder of WebM files in and we extract audio in parallel. Pro users get more parallel workers; on a 50-file batch this is the difference between 90 seconds and 8 minutes.
Will the AMR file be tagged with title / artist / album?
+
If the WebM container has chapter or stream metadata, we copy artist / title / album fields into the AMR container where the AMR format supports tags. Otherwise the AMR file is untagged — use a tag editor (Mp3tag, Picard) post-export for richer tags.
How long does extracting AMR from a WebM file take?
+
Audio extraction is much faster than video re-encoding — typically 5-15% of source duration. A 1-hour WebM -> AMR finishes in 3-9 minutes on the standard pipeline.
Can I extract just a section of the WebM audio as AMR?
+
Not in this single tool — extract the full audio as AMR here, then use /audio-trim/ or /audio-cutter/ to clip the section. The two-step path is faster than a combined operation because we avoid re-decoding the whole file twice.
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 AMR 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 "audio stream" option to explicitly pick stream 0, 1, etc., or re-mux all streams to a multi-track AMR container where AMR supports it.
Can the AMR extraction be stereo / mono / 5.1?
+
Channel layout is preserved from WebM by default — a 5.1 WebM produces a 5.1 AMR where the codec supports it (AAC, FLAC, OGG, Opus). You can force stereo or mono via the channel-downmix option, which is useful for podcast workflow.
Does the extracted AMR 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. Advanced options expose a "device" preset that picks the AMR codec most likely to play on your target.
