Is this tied to one store?
No. This page is intentionally generic and is meant for alternative Android stores or third-party app marketplaces that do not fit a more specific store flow.
Can I still switch the canvas and pacing?
Yes. The page opens with a generic app launch setup, but the same arrange, canvas, pacing, and export controls remain available.
Does export remain local-only?
Yes. Preview and export stay on the device in the browser, without server-side video rendering.
Which format should I choose?
WAV if the audio is going into an editor or a transcription tool and will be processed again, since it is uncompressed and adds no further loss. MP3 or M4A if the file is going straight into a player or a phone, where the size saving matters more than the last few percent of fidelity.
Does 320 kbps make the extraction better than 192?
Marginally, and only up to the quality of the source. The audio in a video is usually AAC at 128 to 192 kbps already, so re-encoding it at 320 preserves that ceiling and doubles the file size. 192 is a sensible default for most video soundtracks.
Why is my WAV file so much bigger than the video's audio?
Because WAV stores every sample uncompressed. 16-bit stereo at 44.1 kHz is 1411 kbps regardless of content, roughly 10 MB per minute, while the compressed source might have been 128 kbps. The size buys you a format that no further lossy stage has touched.
Can I extract audio from a video that is on YouTube or a website?
Not from a URL. The tool works on a file you already have on your device, because everything runs locally in the browser and there is no server fetching anything on your behalf.
Does the exported audio keep the title, artist, or cover art?
No. The export writes the audio stream only. Tags and artwork are not carried across, so add them afterwards in your player or a tagging tool if you need them.
