Transfer Function vs AV Synth

Transfer Function is a dual-FFT acoustic analysis app that is used for sound system audio analysis. Since it can operate with music as the signal source, it can be used during a musical performance to monitor and turn the system equalization during the show. Transfer function includes: -- Magnitude Graph -- Phase Graph -- Coherence Plot -- Delay Finder -- Signal Generator Normally a transfer function requires a two-channel interface, and that is true with this one, also, if you want to use it with program material (music). However, you can use our Transfer Funciton with the internal iOS microphone, if you can send the pink noise generator output to the sound system input. In this configuration, the internal generator is routed back to the input as the reference channel. You can measure delay, magnitude, and phase using this setup. When you use Transfer Function with a two-channel audio interface to run, such as the Studio Six Digital iAudioInterface2, then you can also use any audio source as the test signal, including music.

AV Synth – Visual Instrument is a real-time procedural graphics engine for creating reactive, layered visual compositions. Design, blend, and modulate up to five independent visual layers, each powered by live-generated visuals and chained effect processing. Build complex effect chains per layer, automate parameters to your music, and sculpt motion, color, and dynamics in real time—just like playing a visual instrument. Every creation can be saved as a preset and recalled instantly for live performance or studio work. The PRO version unlocks high-quality video recording and NDI network streaming for professional workflows. This app is designed for: - Live visual performance - Audio-reactive motion graphics - Experimental visual synthesis https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
