LARSA Analyzer vs Open Sound Meter

LARSA, or Loudspeaker And Room System Analyzer, is a powerful impulse response measurement and analysis tool. It is ideally suited for measuring loudspeakers in rooms, multi-speaker setups, car audio systems, home theater systems or larger, installed loudspeaker systems. It is an easy way to profile a system and give you the information you need to equalize or tune your loudspeakers for the best possible performance in your listening space. LARSA brings measurement power and convenience previously available only on desktop computers. Key Features of LARSA include: * Easy-to-learn single-tap recording of an impulse response. * IR averaging features. Perform test/re-test analyses of measurements or a make a spatial average. * IR windowing features. * Energy Time Curves. * Delay time calculation for time-alignment in bi- and tri-amp applications. * Save and recall functionality. * Full iCloud support for easy access to your measurements on your desktop or laptop.

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.
