Spectrum Analyzer RTA vs Open Sound Meter

***** "As a former IEEE Technical Committee Chair for Signal Processing, I find this app amazingly flexible and useful. Works very well with its proper designed-in control selections." - Roblake Spectrum Analyzer for iOS is a powerful real-time audio analysis app. Designed with musicians and recording engineers in mind, it can also be used by anyone interested in the world of sound. Ideal for room tuning or speaker tuning, the app enables portable, precision audio measurement and visualization. Feature Highlights: ● Octave Band Real Time Analyzer ● FFT Plot (Fast Fourier Transform) ● Spectrograph module ● Test Tone and White/Pink Noise Generator ● Native iPhone X graphics >>> Check out the demo videos at SpectrumAnalyzerApp.com Audio input may be acquired via the built-in microphone or an external measurement microphone. For best results we recommend using a calibrated measurement microphone connected via USB audio interface or iPhone dock connector. This allows for high precision and flat frequency response, as well as for stereo input.

Open Sound Meter is an application for tuning and controlling audio systems in real-time. Allows to measure and analyze: - Spectrum - SPL (RMS, Leq) - Magnitude - Phase - Group delay - Phase delay - Coherence - Impulse - Step - Spectrogram - Impedance - Nyquist plot - Crest factor You can store any result. Stored measurement can be adjusted by gain, delay and polarity, adjusted with filters, equalization. Math function gives you a possibility to average your measurements, virtually join them and predict how they will sound together. For better results, you can apply calibration files for your microphones. For the measurement, you can use any iOS compatible audio interface or connect to your mixing console. Save the project on the device or in iCloud. Direct connection works with Behringer X32, Midas M32, Allen&Heath Qu, DiGiCo S21/S31/SD12/UB-MADI, Yamaha TF and other consoles that have audio over USB. For Yamaha CL/QL you can use Dante AVIO adapter.
