WAV is uncompressed lossless audio — pristine but large (~10 MB per minute at CD quality). Convert to WAV when your destination is audio production (DAWs like Logic, Ableton, Pro Tools all use WAV natively), voice-over delivery, or when a broadcaster / stock-audio marketplace specifies uncompressed. Never for casual listening — file sizes make no sense.
Pulling the soundtrack out of a video means dropping every video frame and keeping only the audio stream — smaller file, listen-only content.
Files up to 10 MB on the free plan, up to 1 GB on Pro — enough for lecture recordings, music videos, podcast video versions, and screen captures. Long videos (hour-plus) need Pro because the audio track alone can push past the free ceiling.
For voice content (interviews, lectures, podcasts), 128 kbps WAV is more than enough. For music, aim higher — 192 kbps for casual listening, 320 kbps if you want transparency to the source. The source can't go higher than it already is; if the video's audio was already 128 kbps AAC, exporting at 320 kbps just makes a bigger file.
Extraction is fast — a 30-minute video typically produces its WAV in a few seconds. Both the video you uploaded and the extracted audio are permanently deleted from our servers within 30 minutes.
A VOB container holds separate video and audio streams. Extraction reads the audio stream, re-encodes it (or copies it, if the target codec matches) into your chosen WAV container, and throws away the video entirely. Metadata like title and track info carry over where the format supports it.
Six scenarios where extracting audio to WAV solves a real problem.
A recorded lecture, webinar, or class captured as VOB carries hours of good audio and a static talking head. Extracting to WAV produces something you can listen to on a commute — much smaller, playable on any audio app.
For music videos of tracks you own, extracting the WAV lets you add the song to your regular listening rotation without needing to keep the video around. (Do keep an eye on rights — extraction from third-party sources isn't a licence.)
Recording a video interview and then distributing the audio-only version to podcast platforms is standard practice. Extracting to WAV gives you the podcast episode without touching the video edit.
Whisper, Otter, and every other transcription service accept audio directly. Uploading video wastes bandwidth and, in some cases, is rejected outright. Extract to WAV first, upload, get the transcript back in a fraction of the time.
Sound effects and short clips extracted from videos become WAV files ready to import into audio editors, DAWs, or ringtone makers. Video is unnecessary baggage for these use cases; extracting saves the round-trip.
A 1 GB VOB lecture recording carries maybe 60 MB of actual audio. If the video track is disposable — say, a talking head — extracting to WAV cuts storage by 90% while preserving the content that matters.
VOB (Video Object) is the core data format used on DVD-Video discs. VOB files contain multiplexed MPEG-2 video, audio (AC3/DTS/PCM/MPEG), subtitles, and DVD navigation data within the VIDEO_TS folder of a DVD. Each VOB file can hold up to 1 GB of content, with DVDs typically splitting a movie across multiple VOB files.
VOB files are primarily encountered when ripping or backing up DVD collections, or when working with legacy video archives. Since modern devices and platforms no longer natively support DVD playback, converting VOB files to MP4 or MKV is essential for preserving and accessing DVD content on computers, phones, and streaming devices.
