Audio RTA

Audio RTA is a real-time octave RTA 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 the sounds of musical instruments.

Features

- Octave RTA analyzer: bands - full, 1/3, 1/6, 1/12 (RMS values)

- 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

- Max/min values

- 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)

- 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.
