## Transfer Function Description
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. 

See our website for more information.

## Transfer Function Reviews in Vereinigte Staaten

### *---- "Unusable on 5th Gen iPad Air"
Jan 8, 2025 - Finally got around to testing out the app. In a controlled environment under a variety of circumstances, program is unable to make reliable delay calculations on an up to date 5th gen iPad Air. Even with a “save photo” feature there is no meaningful way to compare two FFT graphs in-app. Major doubt is also thrown on the accuracy of the results given the wild variance in results on the delay finder. 

I downloaded the app with the hopes of using it to calculate software and hardware latencies, as well as quickly time and phase align PA before shows - I can do neither of these things. Disappointed and would like a refund.
