MP4 करण्यासाठी WAV रूपांतरण वारंवार विचारले जाणारे प्रश्न
How do I extract audio from a MP4 video as WAV?
+
Upload your MP4 video. PDF.to pulls the audio track out, encodes it to WAV, and gives you a WAV-only download. The video stream is discarded.
Will the audio in the WAV match the original MP4 quality?
+
If the source audio is already in a codec compatible with WAV, 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 WAV output?
+
मुलभूत 192 kbps. पर्याय पटल 96, 128, 192, 256, व 320 kbps दर्शविते - संगीत करीता जास्त, आवाज करीता कमी निवडा.
Can I extract only part of the MP4 as WAV?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes WAV.
Does the converter handle MP4 files with multiple audio tracks?
+
Yes. If your MP4 has several language or commentary tracks, you can pick which one(s) to extract as WAV in the options panel.
Will the WAV output have the same sample rate as the source?
+
मुलभूतरित्या होय. तुम्ही स्पष्टपणे विनंती न केल्यास आम्ही रिसेम्पलिंग करीत नाही. 48 kHz चित्रपट स्त्रोत पासून संरक्षित केले जाते, 44. 1 kHz संगीत स्त्रोत पासून.
Is the MP4 to WAV extraction free?
+
Yes, within the free size limit. PRO supports much larger MP4 files and parallel batch extraction.
Does PDF.to read or store my MP4 content?
+
No. The MP4 video and the WAV audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple MP4 files?
+
Yes — drop a folder of MP4 videos and you will get a ZIP of WAV files back, one per source video.
Will the WAV preserve tags and metadata?
+
Title, artist, and album tags are populated from the MP4 container metadata when available. You can edit them after extraction with our audio-tag tool.
स्ट्रीमिंग व्हिडीओ URLs वर रूपांतरक कार्य करते का?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the MP4 legally first, then upload it for WAV extraction.
Why is the WAV file much smaller than the MP4 video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the WAV, which is why it can drop from gigabytes to a few megabytes.
