CuSnP is an Audio Unit Extension, or AU, for the iPhone and iPad. This application is simply a container for the AU and serves only as the documentation. CuSnP must be used in some sort of AU host or DAW application. CuSnP is a sympathetic string simulation. Input audio excites the strings and causes them to resonate much like the open strings on a piano will resonate when some other sound source excites them.

ToneBoosters GonioMeter is a one-stop stereo image analysis AUv3 plug-in. Easily identify stereo image imbalance or frequency ranges with negative correlation. Ensure that the content you create is of high quality and mono down-mix compatible, an essential requirement for mobile entertainment! The ToneBoosters GonioMeter stand-alone app captures the microphone input and processes the signals in real time. Since most iOS devices only have mono microphone capabilities, we strongly suggest to use the integrated AUv3 plug-in (app extension) version instead. 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 GonioMeter will appear in the list of Audio Unit extensions for effect plug-ins. Key features: - Real-time goniometer to inspect stereo image waveforms - Real-time correlation meter and correlation spectrum meter - Real-time stereo balance an stereo balance spectrum meter - Color themes for the user interface - Max screen support in Garageband - 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.
