Spectrayzer app for iPhone and iPad

Spectrayzer transforms your iPhone/iPod touch into a real-time FFT Analyzer.
Spectrayzer is a Monaural FFT Analyzer that examines an audio signals frequency.
It also shows the frequency of a sound in a graph.

Features:
- The FFT Analyzer focuses on the human audible range (up to 20kHz).
- The vertical axis shows each frequency volume in dB, while the horizontal axis shows a logarithmic frequency scale in Hz.
- Adjust the volume using the input volume slider on the right side of the main window.
- Select a FFT Size from 256, 512, 1024, 2048 and 4096. The higher number, the more detailed the frequency analysis and the slower the display speed.
- Suitable for detecting a howling frequency or for room tuning.

How to use:
First Screen - FFT Screen
- First, attach a microphone or a device with a built-in mic to a Dock connector, then launch the application.
