If you order a complete solution from Noldus Information Technology, you will obtain one of the computers listed below or their successors, with UltraVox XT installed and ready to use.
Operating system
▪UltraVox XT 4 supports Windows 11 Pro and was tested on Windows 11 Pro, version 23H2.
▪Shorter tests (no recording, only import of audio files) have been performed on Windows 10 Pro, 22H2, with no issues.
▪Processor: Intel Core i7-14700, 20 CPU cores, 3.4 GHz.
▪Hard disks: M.2 1TB PCIe NVMe SSD.
▪Graphics card: NVIDIA T1000, 4 GB GDDR6.
▪Operating system: Windows 11 Pro.
▪Processor: Intel Core Ultra 7 155H vPro Essentials, 16 cores, up to 4.8 GHz
▪Internal memory: 16 GB DDR5.
▪Hard-disks: M.2 2280 1 TB PCIe NVMe SSD.
▪Graphics card: NVIDIA RTX 1000, 6 GB GDDR6.
▪Operating system: Windows 11 Pro.
USB ports
With Noldus microphones, we recommend to use USB 3.0 ports.
▪For USB 3.0: the PC must have as many ports as microphones.
▪For USB 2.0: the PC must have as many controllers as microphones. To check how many USB2 controllers are present on your computer, in the Control Panel choose System and Security > Device Manager. Under Universal Serial Bus Controllers check the items named “USB2”.
▪When using 384 kHz microphones, each microphone must be connected to one USB controller. If you connect multiple microphones to USB ports which shares the same USB controller, Windows recognizes the devices but signals won’t be recorded. Therefore, when using multiple microphones of this type, we recommend to use a multi-port USB 3.0 interface card (see Install the USB 3.0 interface card). Alternatively, use a powered USB 3 hub, or add a USB 3.0 card to the PC for each microphone.
note A powered, or active, USB hub is powered through a wall outlet to bring each hub port to the same energy level as an on-system port.
tip USB 3.0 connectors and ports can be recognized by their symbols, and often also by their blue color coding.
USB 3.0 PCIe interface card
UltraVox XT has been tested with the Fresco Logic U3X4-PCIE4XE111 rev 1.1 PCIe interface card to connect multiple USB 3.0 microphones. See Install the USB 3.0 interface card
Disk space
A 10-minute recording with one microphone requires:
▪For 384-kHz microphones, approx. 400 MB.
▪For 250-kHz microphones, approx. 300 MB.
The maximum file size, for all microphones, is about 4 GB per microphone. The maximum recording duration depends on the type of microphone.
UltraVox XT has been tested with the following USB 3 hub:
▪D-link 4-port DUB-1340, with bit rate 5 Gbps.
In all cases we recommend to use a USB hub compatible with USB 3.0.
▪For ultrasonic measurements, you must use the microphones that come with UltraVox XT.
▪Maximum number of microphones: 4. However, when using 384-kHz microphones and a laptop computer (Dell 7510), we recommend to use up to three microphones.
note The maximum number of microphones also depends on your UltraVox XT license. See Request a license
▪Standard microphones (for human audible vocalizations) have not been extensively tested with UltraVox XT. When using these microphones, the maximum sampling frequency is set to the standard 44100 Hz for human audible vocalizations. UltraVox XT will not record ultrasonic frequencies. note A third party microphone can only be used when it fully supports a 44100 Hz sample rate.
▪The maximum recording duration depends on the microphones being used. See Recording sound
Sound files
You can import sound stored in WAV files (*.wav), recorded in Windows PCM format, mono, with 16-bit depth. See Import sound files
tip If your audio files are stereo or with 32-bit depth, resample them in software like Audacity and export them as WAV files.
