AVI に WAV 変換FAQ
How do I extract the audio from a AVI file as WAV?
+
Upload the AVI file and we demux the audio track, then transcode to WAV. There is no second video pass and no quality loss beyond the WAV codec itself.
What audio bitrate does the WAV file use?
+
Default WAV bitrate is 192 kbps (transparent for music). You can override to 320 kbps (audiophile) or 96-128 kbps (voice / podcast / smaller file). The choice is exposed in the advanced options.
Will I lose audio quality going from AVI to WAV?
+
If the WAV format is lossless (WAV, FLAC), you keep every sample exactly. If WAV is lossy (MP3, AAC, OGG), the WAV codec recompresses — quality depends on the bitrate and source audio. We default to 192 kbps which is transparent for almost all content.
Does the extracted WAV keep the original sample rate?
+
By default yes — a 48 kHz audio track in AVI becomes 48 kHz in WAV. If you need 44.1 kHz (CD-quality) for compatibility with older players, the advanced options include a sample-rate dropdown.
Can I extract audio from multiple AVI files to WAV in one batch?
+
Yes — drop a folder of AVI files in and we extract audio in parallel. Premium users get more parallel workers; on a 50-file batch this is the difference between 90 seconds and 8 minutes.
Will the WAV file be tagged with title / artist / album?
+
If the AVI file has chapter or stream metadata, we copy artist / title / album fields into the WAV container. Otherwise the WAV file is untagged — use a tag editor (Mp3tag, Picard) post-export if you need richer tags.
How long does extracting WAV from a AVI file take?
+
Audio extraction is much faster than video re-encoding — typically 5-15% of the source duration. A 1-hour AVI → WAV finishes in 3-9 minutes on the standard pipeline.
Can I extract just a section of the AVI audio as WAV?
+
Not in this tool — extract the full audio as WAV here, then use /audio-trim/ or /audio-cutter/ to clip the section. The two-step path is usually faster than a combined operation.
Is my AVI file private during audio extraction?
+
Yes — same privacy model as every conversion: isolated workers, automatic deletion within minutes, no human review of content. See /privacy/.
Why does my WAV file have silent gaps?
+
Silent gaps usually mean the AVI file had a multi-track audio layout and we picked the wrong stream. Use the advanced "audio stream" option to explicitly pick stream 0, 1, etc., or re-mux all streams to a multi-track WAV container if WAV supports it.
Can the WAV extraction be stereo / mono / 5.1?
+
Channel layout is preserved from AVI by default — a 5.1 AVI produces a 5.1 WAV where the codec supports it (AAC, FLAC, OGG). You can force stereo or mono via the channel-downmix option, useful for podcast workflow.
Does the extracted WAV play on iPhone / Android / car stereo?
+
MP3 plays everywhere. AAC / M4A plays on Apple and most Android. OGG / Opus needs a recent player on iOS. The advanced options expose a "device" preset that picks the WAV codec most likely to play on your target.
