Bawo ni mo ṣe lè yọ àwòrán àwòrán kuro nínú WebM bí AMR?

Upload the WebM file and the converter demuxes the audio stream from the WebM container, then transcodes it into AMR. Video frames are discarded — no second video pass, no quality loss beyond what the AMR codec itself introduces.
Which audio track gets extracted when my WebM has several?
+
By default stream 0 (the first audio track, usually the main mix). If your WebM carries commentary, dubs, or descriptive audio on additional tracks, the advanced "audio stream" picker lets you pick 1, 2, 3... explicitly. The track list is shown in the upload preview so you do not pick blind.

If the AMR format is lossless (WAV, FLAC, ALAC), every original sample is preserved. If AMR is lossy (MP3, AAC, OGG, Opus), the codec recompresses — at 192 kbps the difference is inaudible for most content; at 96 kbps you may hear cymbals or sibilants softening. The WebM container has no influence on this — only the codec settings matter.
Does the extracted AMR keep the WebM sample rate?
+
By default yes — 48 kHz WebM audio becomes 48 kHz AMR audio, 44.1 kHz becomes 44.1 kHz. If you need to downsample for compatibility (e.g. 96 kHz studio masters to 44.1 kHz CD-quality AMR) the sample-rate dropdown does this with high-quality resampling.
Can I batch-extract AMR audio from a folder of WebM files?
+
Yes — drop a folder of WebM files into the upload zone and we run extraction in parallel. Premium gets more parallel workers; on a 100-file batch (typical music-video collection) this is the difference between 90 seconds and 8 minutes.
Ìgbà wo nínú tí a bá gbá AMR láti inú aago-1 WebM?
+
Audio demux + transcode runs 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. If the AMR codec matches the source codec already in the WebM (common for AAC inside MKV / MP4), it is a pure remux and runs in seconds.

Is my WebM private during audio extraction?
+
Yes — same privacy model as every conversion. Source WebM and output AMR are processed in isolated workers and deleted within minutes. We never play, store, or share content. See /privacy/.
Kini idi ti mò ti ní àwọn ààyè ìtàjú àti àwọn àwòrán àìdájú nínú AMR mìí?
+
Almost always a stream-index mismatch — your WebM had a multi-track audio layout and we extracted the wrong stream (e.g. the silent descriptive audio track instead of the main mix). Re-run with the advanced "audio stream" option set to the right index, or pick "all streams" to extract every track as a separate AMR file.

MP3 plays universally. AAC / M4A plays on Apple and most Android, including factory car stereos from 2014+. OGG / Opus needs a recent player and may not work in older infotainment systems. The advanced device-target dropdown picks the safest AMR codec for the target you select.
