FRKB ~ Rapid Audio Organization Tool


FRKB is a cross-platform desktop application designed for audio professionals (such as DJs). The current beta version is compatible with Windows and will be adapted for macOS once stable. It is still under active development.

Core Features:

  • Portable: Easily transfer the database to mobile devices for on-the-go use.
  • Audio Fingerprint Deduplication: Identify and exclude duplicate tracks using audio fingerprint technology, providing prompts during import to keep your music collection clean and efficient.
  • Ergonomic Shortcuts: Ergonomically designed shortcuts that allow most operations to be performed with the left hand, making the organization process smoother and more efficient.
  • Direct File Management: When adding tracks, FRKB directly manages the audio files themselves, ensuring that the organization results are immediately reflected in the computer’s folders, achieving a “what you see is what you get” effect.
  • Waveform Visualization: Provides audio waveform display.
  • BPM Analysis: Displays BPM information.

Modern Flyouts ~ Windows Volume Flyout


This application aims to provide a Fluent Design System based replacement for the old, built-in, Metro Design based Audio/Airplane mode/Brightness flyouts in Windows which are shown while pressing the media or volume keys or even the brightness keys or when airplane/flight mode is toggled.

In case of Windows 11, this application will have the same UI but will provide additional features and customizability compared to the built-in redesigned flyouts.

BassBoom ~ Music App & Library


BassBoom is a music player made with C# using the fast mpg123 library as the native backend that handles the music playback and song information, including the playback device information.

This library is a viable library aimed for cross-platform music playing because we’ve selected mpg123 as the MP3 backend library for its ease of use and for its fast music playback. This library is frictionless as it aims for stability and cross-platform compatibility.

In addition to your regular music files, BassBoom also supports online MPEG radio stations that you can use to play your own favorite radio stations, as long as they don’t use AAC or any other codec that BassBoom doesn’t support.

WACUP ~ Emulated Winamp


A media player that’s made to emulate some of your favourite media players from the past & bring them into the future. WACUP (which can be pronounced as wakeup or wac-up or however you prefer it in your native tongue) is my vision of what a media player should be whilst still being compatible with the plug-ins for some of the most popular media players that you are used to. My plan is to include bug fixes, updates of existing features & most importantly new features with the goal to eventually become its own highly compatible media player.

WACUP is heavily based around a plug-in system making it simple to tailor you WACUP install to be what you want it to be. When it’s finally out of being a preview build, an SDK will eventually be offered so new plugins can then be made to add additional features.
