Odd, misbranded in my opinion
Its not *bad* but it should have a camera as a thumbnail rather than headphones, or maybe both. What it does is apply an effect (out of a small handful to choose from) to an audio file or youtube video. Then you press play and hit record to record the sound thats currently playing onto the video that you are currently recording. The effect is not applied live so you can only hear it after the video is finished. If there is ever an update I hope it allows you to listen to or preview the sound with selected effect before taking video.
