MPEG به AAC سوالات متداول تبدیل
How do I extract audio from a MPEG video as AAC?
+
Upload your MPEG video. PDF.to pulls the audio track out, encodes it to AAC, and gives you a AAC-only download. The video stream is discarded.
Will the audio in the AAC match the original MPEG quality?
+
If the source audio is already in a codec compatible with AAC, 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 AAC output?
+
پیشفرض ۱۹۲ کیلوبایت بر ثانیه است. قاب گزینهها ۹۶، ۱۲۸، ۱۹۲، ۲۵۶ و ۳۲۰ کیلوبایت بر ثانیه را نمایش میدهد — برای موسیقی بالاتر را انتخاب کنید، برای صدا پایینتر.
Can I extract only part of the MPEG as AAC?
+
Yes. Use the trim controls on the upload preview to set start and end times before extracting, and only that range becomes AAC.
Does the converter handle MPEG files with multiple audio tracks?
+
Yes. If your MPEG has several language or commentary tracks, you can pick which one(s) to extract as AAC in the options panel.
Will the AAC output have the same sample rate as the source?
+
به صورت پیشفرض ، بله. ما نمونهگیری مجدد نمیکنیم مگر اینکه شما به طور صریح درخواست آن را بدهید. ۴۸ کیلوهرتز از منابع فیلم ، ۴۴٫ ۱ کیلوهرتز از منابع موسیقی حفظ میشود.
Is the MPEG to AAC extraction free?
+
Yes, within the free size limit. PRO supports much larger MPEG files and parallel batch extraction.
Does PDF.to read or store my MPEG content?
+
No. The MPEG video and the AAC audio output are deleted within an hour. Conversion runs in an isolated worker.
Can I batch-extract audio from multiple MPEG files?
+
Yes — drop a folder of MPEG videos and you will get a ZIP of AAC files back, one per source video.
Will the AAC preserve tags and metadata?
+
Title, artist, and album tags are populated from the MPEG container metadata when available. You can edit them after extraction with our audio-tag tool.
آیا مبدل برای نشانیهای وب جریانی ویدئو کار میکند؟
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the MPEG legally first, then upload it for AAC extraction.
Why is the AAC file much smaller than the MPEG video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the AAC, which is why it can drop from gigabytes to a few megabytes.
