Volume Studio uses Python 3.14.4, NumPy 2.4.4, PySide6/Qt 6.11.1 and Shiboken6 6.11.1. The launcher is built with PyInstaller 6.20.0.

Qt/PySide6/Shiboken6 are used under the GNU Lesser General Public License version 3. Copies of LGPL/GPL texts and dependency notices are included. Shared libraries are unmodified and extracted temporarily from the standalone EXE at launch. The included application source and build specification allow rebuilding with compatible modified libraries. Nothing in this distribution restricts modification, relinking or reverse engineering for debugging changes to these libraries.

Exact Qt, Qt SVG, Qt image formats and PySide/Shiboken source archives are supplied in Dependency sources. Those archives include third-party notices, source and build instructions. Official source repositories:

NumPy and its bundled components retain their respective notices in the numpy directory. Python licensing includes its bundled library notices. PyInstaller includes its bootloader exception. Microsoft Visual C++ runtime DLLs are unmodified redistributable runtime components. The Adobe Audition icon identifies the optional external Adobe application; Adobe software is not included.
