3GP до AMR Найчастіші запитання щодо конверсій
How do I extract audio from a 3GP video as AMR?
+
Upload your 3GP 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 3GP 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?
+
Типово, 192 кбіт/ с. На панелі параметрів буде показано 96, 128, 192, 256 і 320 кб/ с } обрати вище для музики, нижче для голосу.
Can I extract only part of the 3GP 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 3GP files with multiple audio tracks?
+
Yes. If your 3GP 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?
+
Так, типово. Ми не переписуємо, якщо ви не надсилаєте явного запиту. 48 кГц зберігається з джерел фільмів, 44. 1 кГц з джерел музики.
Is the 3GP to AMR extraction free?
+
Yes, within the free size limit. PRO supports much larger 3GP files and parallel batch extraction.
Does PDF.to read or store my 3GP content?
+
No. The 3GP video and the AMR audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple 3GP files?
+
Yes — drop a folder of 3GP 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 3GP container metadata when available. You can edit them after extraction with our audio-tag tool.
Чи працює перетворювач для потокових відео URL?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the 3GP legally first, then upload it for AMR extraction.
Why is the AMR file much smaller than the 3GP 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.
