Soundbeam helps you see what everyday sounds look like and visualizes sounds you can't even hear! Plug in your electric guitar, a mic or any other (hi-Z) device to your mini-jack input and get accurate measurements. You can always use the built-in mic. We paired stylish controls and an old-school interface with high precision signal processing algorithms, creating a new way to experience sound. Soundbeam is an real-time audio analyzer (RTA) that processes the input of your microphone displaying it like a classic oscilloscope. It also features a spectral visualization of the audio using high resolution fourier transform (FFT) for accurate measurements. Get a dose of nostalgia with Soundbeam now! Key Features: * Spectrum and waveform views * Recording functionality * Gesture support for frequency range and intensity levels adjustment * Visualization controls * ...and one more thing! Plug in your headset or guitar and watch what happens! Controls: * While in "spectrum mode", pinch the monitor vertically or horizontally to change frequency range and intensity levels respectively. You can also pan the soundwave with one finger. * In "waveform mode" pinch the screen vertically to adjust intensity levels. * Double tap on the screen to reset view. * Tap & slide the intensity knob horizontally to adjust it.

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.
