A 16-bit stereo WAV at 44,100 Hz runs about 10 MB per minute of audio, so a five-minute clip lands near 50 MB regardless of how compressed the original video was. WAV is uncompressed PCM, which is why it is far larger than the source's encoded audio track. Size scales directly with three things: duration, sample rate, and channel count. Switching to mono roughly halves the file, and dropping the sample rate to 22,050 Hz halves it again, so a mono clip at 22,050 Hz is about a quarter the size of stereo at 44,100 Hz. Before you extract, the tool shows the video's duration and an estimated WAV size that updates as you change settings, so you can see exactly what you are committing to and pick the trade-off that fits your storage.

Pick 44,100 Hz (CD quality) when you want to preserve full fidelity, such as music, mixed audio, or anything you may edit or master later — it captures the complete frequency range a video soundtrack contains. Choose 22,050 Hz (FM-radio quality) for spoken-word content like interviews, podcasts, and lectures where high-frequency detail does not matter and you want a smaller file. Use 11,025 Hz (telephone quality) only for voice memos or speech destined for transcription, where intelligibility is all that counts. Lower rates discard high-frequency information and cannot be restored by raising the rate afterward, so when in doubt, extract at 44,100 Hz and downsample later. The tool resamples cleanly using an offline audio context, so whichever rate you select is applied accurately during extraction. Set your sample rate above before clicking extract.

Stereo keeps two separate channels (left and right), preserving any spatial placement and width in the original soundtrack, while mono collapses everything into a single channel. The practical difference is file size and intent: mono produces a file roughly 50 percent smaller because it stores half the samples, which is ideal for speech, voice notes, interviews, and audio headed for transcription, where stereo separation adds nothing useful. Keep stereo for music, podcasts with panned voices, or anything where the left-right image matters. By default the tool extracts stereo from the source's first two channels; flip the channels switch to mono and the estimated size drops immediately so you can see the saving before committing. Choose mono or stereo in the audio settings, then extract and download your WAV.

Two things cause this. First, the format or codec may not decode in your browser — MP4 and WebM are the most reliable because browsers handle them consistently, while AVI, MKV, and clips using older or unusual codecs sometimes fail outright and return an error rather than a partial file. The fix is to remux the source to MP4 first, then try again. Second, the file may have no audio track at all; a silent or video-only clip gives the tool nothing to extract, so it produces nothing. There is no hard length limit, but very large videos use proportionally more memory because the entire track is decoded at once, so extremely long clips are best trimmed before extraction. If you hit an error, convert to MP4 or shorten the clip and re-upload it here.

The extraction itself is lossless in the sense that WAV is an uncompressed 16-bit PCM format, so nothing is re-compressed or thrown away the way it would be if you re-encoded to a lossy format. However, the output can only be as good as the audio already inside the video, since that track was compressed when the video was encoded — extracting cannot add back detail the source never stored. Your settings also matter: keeping the sample rate at 44,100 Hz and stereo preserves the full quality of the original track, while choosing a lower rate or mono deliberately discards information to save space. For an archival or editing master, extract at 44,100 Hz stereo and convert to a compressed format later only if you need a smaller file. Upload your clip and extract at full settings here.
