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.
