Could work as a standalone universal audio engineering measurement solution and as a remote wireless control and monitoring for desktop instances.

Open Sound Meter is an application for tuning audio systems in real-time.
It allows you to measure all needed functions:
- Spectrum
- 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.

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.

On M1 you need to select your working audio device as the defaults system audio input and output.

Nearly Perfect tool for the job

Love the software. Support the dev! Like Smaart lite, but so cheap. I get results w this so quickly and the IR delay finder is eerily accurate
