WMV đến WAV Câu hỏi thường gặp về chuyển đổi
How do I extract audio from a WMV video as WAV?
+
Upload your WMV 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 WMV 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?
+
Mặc định là 192 kbps. Tùy chọn trên bảng hiển thị 96, 128, 192, 256, và 320 kbps — chọn cao hơn cho âm nhạc, thấp hơn cho giọng nói.
Can I extract only part of the WMV 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 WMV files with multiple audio tracks?
+
Yes. If your WMV 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?
+
Có theo mặc định. Chúng tôi không lấy mẫu lại trừ khi bạn yêu cầu rõ ràng. 48 kHz được bảo tồn từ nguồn phim, 44. 1 kHz từ nguồn âm nhạc.
Is the WMV to WAV extraction free?
+
Yes, within the free size limit. PRO supports much larger WMV files and parallel batch extraction.
Does PDF.to read or store my WMV content?
+
No. The WMV video and the WAV audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple WMV files?
+
Yes — drop a folder of WMV 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 WMV container metadata when available. You can edit them after extraction with our audio-tag tool.
Ứng dụng chuyển đổi có thể dùng với URL video không?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the WMV legally first, then upload it for WAV extraction.
Why is the WAV file much smaller than the WMV 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.
