System Requirements

This page lists the hardware and software prerequisites for installing and running V-Listen. Meeting the recommended specifications ensures optimal performance, especially when working with long multichannel recordings or computationally intensive analyses such as time-varying loudness or high-resolution spectrograms.

Software Requirements

Component	Minimum	Recommended
Operating System	Windows 10 x64 (version 1903 or later)	Windows 11 x64 (latest update)
.NET Framework	4.8	4.8 (included with Windows 10 1903+ and Windows 11)
Visual C++ Redistributable	2015–2022 x64	Latest available from Microsoft

Note: V-Listen is a 64-bit application exclusively. 32-bit (x86) versions of Windows are not supported. ARM-based Windows devices (e.g., Surface Pro X) are not officially tested.

Hardware Requirements

Component	Minimum	Recommended
Processor	Intel Core i5 (8th gen) or AMD Ryzen 5	Intel Core i7/i9 (12th gen+) or AMD Ryzen 7/9
RAM	8 GB	16 GB or more
Disk Space (Application)	500 MB	1 GB (includes example projects and templates)
Disk Space (Data)	Varies by project	SSD with 50+ GB free space for recording and result files
Display Resolution	1920 × 1080	2560 × 1440 or higher
GPU	DirectX 11 compatible (integrated graphics acceptable)	Dedicated GPU for large 3D geometry visualization

Memory Considerations

Memory consumption scales with the number of channels, recording duration, and active analysis engines. The following table provides rough guidance:

Scenario	Typical RAM Usage
Single-channel, 30-second recording, FFT analysis	~200 MB
8-channel, 5-minute recording, order + loudness	~1.5 GB
32-channel, 10-minute recording, full spectral + psychoacoustic suite	~6 GB
EMA/ODS with imported geometry (10,000+ nodes)	~4 GB

Optional: Acquisition Hardware

V-Listen supports direct data acquisition from the following hardware frontends. These are not required if you only analyze pre-recorded HDF files.

Device	Driver	Connection	Notes
National Instruments DAQ (USB/PCIe)	NI-DAQmx 2023 Q4 or later	USB / PCIe	Install NI-DAQmx runtime before first use. Supported models include USB-4431, USB-9234, PXIe-4492, and compatible devices.

Network and Licensing

V-Listen analysis does not require a network connection or license server. All computation runs locally on the workstation. An internet connection is only needed for:

Software updates and patch downloads

Supported File Formats

Format	Extension	Access
HDF Recording	`.hdf`	Read / Write
HDF Result	`.hdf`	Read
WAV (PCM, IEEE float)	`.wav`	Read / Write
Universal File Format	`.uff`, `.unv`	Read (FRF import)
STL Geometry	`.stl`	Read
CSV / Text	`.csv`, `.txt`	Read / Write (export)

Next step: Once your system meets these requirements, proceed to the Quick Start Guide to run your first analysis.
