Audio Spectrum is a real-time FFT spectrum analyzer. It gives you a visual representation of an acoustic signal. It can be used to measure the frequency response of audio equipment or to analyze different sounds (e.g. sounds of musical instruments).

Features

- Spectrum analyzer

- SPL Meter (dBFS)

- Fast real-time response

- Sampling rates: 44.1kHz, 48kHz, 96kHz*

- Fast Fourier Transform (FFT)

- Window sizes: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768**, 65536**

- Zoom and pan

- Measure values

- Audio input can be supplied via the built-in microphone and an external microphone (via the USB camera adapter or through the iPhone/iPad dock connector – Core Audio compliant devices)

- Sharing charts (through mail, social networks, clipboard)

- Exporting charts (png) to the iTunes app document folder

- Frequency scale: linear and logarithmic

- Amplitude scale: linear and logarithmic SPL/RMS (dBFS)

- SPL meter weighting: dBZ - linear

*For 96kHz analysis use an external microphone with such capabilities through a USB camera adapter or through the iPhone/iPad dock connector.

**Only available on devices with 64 bit processors – iPhone 5S, iPad Air
