VOB کرنے کے لئے AIFF تبادلوں کے اکثر پوچھے گئے سوالات
How do I extract audio from a VOB video as AIFF?
+
Upload your VOB video. PDF.to pulls the audio track out, encodes it to AIFF, and gives you a AIFF-only download. The video stream is discarded.
Will the audio in the AIFF match the original VOB quality?
+
If the source audio is already in a codec compatible with AIFF, 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 AIFF 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 VOB as AIFF?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes AIFF.
Does the converter handle VOB files with multiple audio tracks?
+
Yes. If your VOB has several language or commentary tracks, you can pick which one(s) to extract as AIFF in the options panel.
Will the AIFF 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 VOB to AIFF extraction free?
+
Yes for files under 100 MB. PRO supports larger VOB files (5 GB) and parallel batch extraction.
Does PDF.to read or store my VOB content?
+
No. The VOB video and the AIFF audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple VOB files?
+
Yes — drop a folder of VOB videos and you will get a ZIP of AIFF files back, one per source video.
Will the AIFF preserve tags and metadata?
+
Title, artist, and album tags are populated from the VOB 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 VOB legally first, then upload it for AIFF extraction.
Why is the AIFF file much smaller than the VOB video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the AIFF, which is why it can drop from gigabytes to a few megabytes.
