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.
