■ Notes on use

- The user is responsible for preparing the video including the sound source that will be the conversion source. This app does not have a video download function
- Although audio extraction is performed from the video, it is not possible to extract only vocals or non-vocal audio.
- Conversion can be performed only with iPhone / iPad, but the conversion time depends on the file size, playback time, and device performance of the conversion source video.
- Although it is a so-called mp3 converter app, it also supports formats other than mp3.
- Some functions require in-app purchase, but all basic functions can be used free of charge.
