To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters Spectrogram will appear in the list of Audio Unit extensions for effect plug-ins. Key features: - Fully resizable (as AUv3 plugin) - Color themes for the user interface - Max screen support in Garageband - Adjustable color themes for UI and for spectrogram independently - Adjustable dynamic range - Adjustable frequency resolution - Adjustable time resolution - Adjustable spectral slope - Spectrogram AGC and dimming support - Show spectrogram and spectrum analyzer as overlay or individually - Spectrum analyzer also supports peak hold - Split-band goniometer for stereo signal analysis (correlation, left/right balance in one or two bands!) - On-screen piano keyboard to map spectrum analyzer to piano notes - Optimised for iPad and compatible with iPhone and iPod Touch What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.
