Volume Limiter is a small application that allows you to set a maximum volume limit on your windows PC. This is designed to protect children from turning the volume up to a level that would damage their hearing.
The application can be password protected to prevent children from changing your defined limit. The application runs in the background and minimizes to the system tray. Volume settings, the lock or unlocked status, and password information are stored in the windows registry. If the application is set to start up upon login (by placing it in the startup group) it will load the previous settings.
This application is compatible with Windows Vista, 7 and 8 and will run on 32 bit or 64 bit systems.

Audio visualization usually relies on hand-crafted features, like intensity, timbre or pitch. These metrics are defined by humans and are biased towards our cultural representation of sound. In this project, we have trained a Neural Net to generate these features directly from spectrograms, in an unsupervised way. We thus get rid of this bias and hope the resulting visualizations can help us perceive music in different ways.
