Real-time Octave RTA Analyzer for Audio Analysis
Audio RTA is a powerful tool that provides real-time analysis of acoustic signals on your iPhone. Developed by Pawel Krzywdzinski, this app is perfect for measuring the frequency response of audio equipment or analyzing the sounds of musical instruments.
With Audio RTA, you can utilize the octave RTA analyzer to visualize the frequency bands, including full, 1/3, 1/6, and 1/12 octave bands with RMS values. The app also features an SPL (Sound Pressure Level) meter, allowing you to measure the loudness of audio signals in dBFS.
One of the standout features of Audio RTA is its fast real-time response. You can rely on accurate and up-to-date information as you monitor the acoustic signals. The app supports multiple sampling rates, including 44.1kHz, 48kHz, and even 96kHz for advanced analysis using an external microphone.
To enhance the analysis, Audio RTA utilizes the Fast Fourier Transform (FFT) algorithm and offers various window sizes for precise measurements. You can zoom in and pan across the charts to focus on specific details, and the app provides max/min values for easy reference.
Audio RTA supports both the built-in microphone and external microphones connected through the USB camera adapter or the iPhone/iPad dock connector, making it flexible for different recording setups. You can easily share the analysis charts through mail or social networks, or export them as PNG images to the iOS 11 Document Browser, including iCloud support.
Whether you are an audio professional, musician, or simply an enthusiast, Audio RTA is a comprehensive tool that provides accurate and detailed audio analysis on your iPhone. It is a must-have for anyone involved in audio equipment testing, music production, or sound engineering.
