How do I extract audio from a FLV video as AMR?

Upload your FLV video. PDF.to pulls the audio track out, encodes it to AMR, and gives you a AMR-only download. The video stream is discarded.

Will the audio in the AMR match the original FLV quality?

If the source audio is already in a codec compatible with AMR, we stream-copy without re-encoding — bit-identical to the original. Otherwise we re-encode at 192 kbps by default for near-transparent quality.

What bitrate is the AMR output?

192 kbps by default. The options panel exposes 96, 128, 192, 256, and 320 kbps — pick higher for music, lower for voice.

Can I extract only part of the FLV as AMR?

Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes AMR.

Does the converter handle FLV files with multiple audio tracks?

Yes. If your FLV has several language or commentary tracks, you can pick which one(s) to extract as AMR in the options panel.

Will the AMR output have the same sample rate as the source?

Yes by default. We do not resample unless you explicitly request it. 48 kHz is preserved from movie sources, 44.1 kHz from music sources.

Is the FLV to AMR extraction free?

Yes for files under 100 MB. PRO supports larger FLV files (5 GB) and parallel batch extraction.

Does PDF.to read or store my FLV content?

No. The FLV video and the AMR audio output are deleted within an hour. Conversion runs in an isolated worker.

Can I batch-extract audio from multiple FLV files?

Yes — drop a folder of FLV videos and you will get a ZIP of AMR files back, one per source video.

Will the AMR preserve tags and metadata?

Title, artist, and album tags are populated from the FLV container metadata when available. You can edit them after extraction with our audio-tag tool.

Does the converter work on streaming video URLs?

No — PDF.to converts files you upload, not third-party stream URLs. Download the FLV legally first, then upload it for AMR extraction.

Why is the AMR file much smaller than the FLV video?

Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the AMR, which is why it can drop from gigabytes to a few megabytes.
