Description

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 image charts (png) to the iOS 11 Document Browser (supports iCloud)
- 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.

Matches our calibrated microphones.

I work in a Modal lab. I downloaded this app just for quick measurements on the fly, to verify my test setups. Works great. The FFT matches our $90,000 analyzes and calibrated microphones. I am impressed to say the least. Please update allowing for triggers.

This app works awesome. Only one upgrade I would suggest would be the ability to take screen shots and a record feature for data. I would still highly recommend.

Needs better programming. Needs averaging and slow response
