Klevgränd has released a music visualizer app, Wizibel, an iOS app that they say imports audio, lets the user tweak a set of parameters and export a high quality video.
The initial version has six themes and each theme contains a set of tweakable parameters for customization like text strings, sizes, colours, images and how audio waveforms/audio visualizations should react to the music.
Pricing and Availability:
Wizibel is launched with a intro price set to $3.99 USD (50% off) and is available on the App Store.
