Faber iOS apps updated with enhanced support for miniDSP USB microphones

June 13, 2019 iOS, iPad, iPhone, News

The latest update to Faber Acoustical’s SignalScope (10.7.2) and SoundMeter (10.4.2) apps includes updated microphone and headset sensitivities for Apple’s newest iPad models as well as enhanced support for USB measurement microphones from miniDSP.

Enhanced support for the miniDSP UMIK-1 and EARS headphone measurement system allows for the input gain to be changed from -31 dB to +24 dB in 1 dB increments while maintaining sensitivity calibration. With a single sensitivity calibration, the input gain can be set to any of those values without the need to re-calibrate.

The addition of support for the miniDSP EARS headphone and in-ear monitor (IEM) measurement system enables the automatic download and application of factory calibration values with the input of a serial number (similar to the miniDSP UMIK-1). The hardware gain, set via the DIP switches on the front of the device, will also be automatically accounted for, so calibrated measurements are assured, regardless of the device configuration. The calibration accuracy depends on the accuracy of the calibration data provided by miniDSP. Manual calibration of each ear microphone is also supported. When the miniDSP EARS hardware gain is changed using the DIP switches on the front of the device, the app will automatically account for the different gain setting to preserve calibration.

The app updates also include various minor bug fixes and cosmetic improvements.

SignalScope apps add support for automatic download and selection of the different frequency response compensation files provided for each EARS device by the manufacturer, miniDSP. These files are stored on your iOS device by SignalScope and can be selected independently for each input channel. Frequency response compensation applies to FFT-based measurements, only.

In the latest version of the Dual FFT Analyzer, available in SignalScope X’s Pro Tool Set subscription and in SignalScope Pro 2018, phase compensation is also applied when a loaded frequency response data file includes phase information (including headphone and IEM calibration files provided by miniDSP). The Dual FFT Analyzer also now includes the ability to select up to 2 Y channels for simultaneous measurement of 2 signal paths or 2 DUT’s (devices under test). This allows for quick measurement and comparison of stereo devices, such as headphones (e.g. using the miniDSP EARS system).
