Release Note | Voyager 2.0

Firmware Voyager 2.0

The new version of the Voyager firmware is packed with new features and improvements. Field calibration, daq mode for Velo 64bit, loudness implementation, just to name a few!

New Features at a glance

  • A new calibration module to calculate the sensitivity of any sensor connected to the Voyager was added. Custom adapters are required to calibrate Microflown probes.
  • DAQ module. Voyager can now be used in combination with Velo 5 (64 bit only) either via USB or Ethernet.
  • Voyager can now be fully controlled remotely, provided that the device is connected to a local network. Mouse, keyboard and mirrored screen on PC are supported using applications such as VNC.
  • Loudness subtab added into the listening and analysis tab, including overall instantaneous loudness.
  • Voyager file browser accessible via Ethernet
  • Additional exporting options were integrated, it is possible to convert the HD5 files to WAV format of 32 or 16 bit including dynamic range settings, enhancing compatibility with third party software.
  • Documentation and API for integrating Voyager DAQ with third applications accessible when connected through Ethernet. Public Github repository accessible for developers.
  • Several internal optimizations were implemented, improving the overall robustness of the system.
  • Added various ease of use features to the user interface, such as a quick panel for viewing network connectivity, shutdown from dashboard or licensing subtab into the "About page".

DAQ Mode with Velo Software

We are excited to announce that with the firmware version 2.0 arriving your Voyager can also be used as portable data acquisition system with our Velo 64Bit software and its applications. There are two options available to interface the Voyager with your computer, either by using the Micro USB or the Ethernet port.

Field Calibration with a sound calibrator

We are excited to introduce a real novelty for Microflown and its sensors. Our latest addition to the sensor family, the so-called PU Voyager, will be the first of Microflown sensors to be compatible with a standard sound calibrator for performing field calibration. This field calibration can be performed before or after your mea­surements as quality check to ensure good functioning of the sensor. It works as follow, a sound calibrator is used to validate the sensor against a known level, for example alt a level of 94dB at a frequency of 1kHz. To accomplish this our team of expert designed a special adapter suited for the PU Voyager probe and compatible with standard in the market available one-inch sound calibrators. On the Voyager device the new firmware offers an intuitive embedded, tool to execute fast and easy a field calibration. After performing the field calibration, the tool allows with one finger tough to update and introduce the new sensitives for the sensors in to the device.

Loudness

Firmware 2.0 introduces a new analysis option; calculation of loudness, including overall instantaneous loudness. Calculations are performed in conformance with ISO 532-1:2017, therefore only available for 48000 Hz sampling frequency. The axes and units can be adjusted using the intuitive touch controlled analyzer settings. This graph on the left shows loudness variations over frequency.

Remote access and control your Voyager device with your smartphone, tablet or laptop

Simply connect your voyager to the same network as your device and you can fully access and control the voyager remotely. Start your recordings or check the FFT in real time. Transfer files and folders easily to your device or enable a network based connection using voyager as portable frontend for Velo 64 bit.

More Flexible & Versatile than ever before. Comprehensive exporting options and Github support

Documentation and API for integrating Voyager DAQ with third applications accessible when connected through Ethernet. Public Github repository accessible for developers. Additional exporting options were integrated, it is possible to convert the HD5 files to WAV format of 32 or 16 bit including dynamic range settings, enhancing compatibility with third party software.
