FlexASIO ~ Flexible Universal ASIO Driver
FlexASIO is a universal ASIO driver, meaning that it is not tied to specific audio hardware. Other examples of universal ASIO drivers include ASIO4ALL, ASIO2KS, ASIO2WASAPI.
Universal ASIO drivers use hardware-agnostic audio interfaces provided by the operating system to produce and consume sound. The typical use case for such a driver is to make ASIO usable with audio hardware that doesn’t come with its own ASIO drivers, or where the bundled ASIO drivers don’t provide the desired functionality.
While ASIO4ALL and ASIO2KS use a low-level Windows audio API known as Kernel Streaming (also called “DirectKS”, “WDM-KS”) to operate, and ASIO2WASAPI uses WASAPI (in exclusive mode only), FlexASIO differentiates itself by using an intermediate library called PortAudio that itself supports a large number of operating system sound APIs, which includes Kernel Streaming and WASAPI (in shared and exclusive mode), but also the more mundane APIs MME and DirectSound. Thus FlexASIO can be used to interface with any sound API available on a Windows system. For more information, see the backends documentation.
Among other things, this makes it possible to emulate a typical Windows application that opens an audio device in shared mode. This means other applications can use the same audio devices at the same time, with the Windows audio engine mixing the various audio streams. Other universal ASIO drivers do not offer this functionality as they always open audio devices in exclusive mode.

Artifact free technical design:
- low ripple and distortion filter implementations
- 64bit floating point internal processing
- oversampled for superior impulse response
Meticulously selected frequencies:
- Baxandall shelving filters
- LF @ 74, 84, 98, 116, 131, 166, 230 and 361 Hz
- HF @ 1.6, 1.8, 2.1, 2.4, 3.4, 4.8, 7.1, 11 and 18 kHz

MusicSync ~ Synchronize Music Libraries
MusicSync is a cross-platform tool that synchronizes your music library between devices and drives with advanced settings.
You can use it through CLI, that makes easy to sync you library with only a click using a script, or through GUI, that is more user-friendly. Here there are two examples:
python musicsync D:/Music sdcard/Music --adb --min-rating 4.5 --output-format opus --output-bitrate 128k python musicsync D:/Music sdcard/Music --adb --min-rating 3 --min-year 2020 --output-format opus --output-bitrate

Windows Media Player Plus ~ Enhance WMP
Windows Media Player Plus! is a free plug-in for Windows Media Player that adds various user interface and playback enhancements.
Features:
- Tag Editor Plus: an alternative for Windows Media Player’s Advanced Tag Editor (screenshot). Tag Editor Plus works on Windows Media Player 12 too, where the original Advanced Tag Editor has been removed.
- Global hotkeys, allowing you to control Windows Media Player from within any running application.
- Party Shuffle: a dynamic playlist that automatically gets filled with randomly picked songs. Of course, you can still add songs yourself, and reorder/remove songs, just like with a normal playlist. Very useful while throwing a party, as a DJ aid, or just for casual listening.
- Real ‘find as you type’ in the media library: you can simply start typing to search, without having to click on the Search field first.
- Disc number (‘set’) support in the media library: shows disc numbers in the Track number column and makes Windows Media Player use the disc numbers for sorting the tracks of an album (screenshot).
- Access the standard Explorer right-click menu of a media file directly from within Windows Media Player (screenshot).
- Restore last active playlist, media item, and playback position at Windows Media Player startup.
- Show currently playing media in Windows Media Player’s title bar (screenshot).
- Advanced playback options: Stop after current and Close after current, to automatically stop playback or close Windows Media Player when the current media has ended (screenshot).
- Let Windows Media Player play/pause when you press the space bar.
- Disable group headers in the Library Pane (screenshot).

- Show currently playing media in Skype’s mood message.
- Access the properties/settings of any Windows Media Player plug-in from within the main menu (Tools – Plug-in properties), without having to go to Options first (screenshot).
- Bring back the “Find in library” right-click option of older versions of Windows Media Player to Windows Media Player 12.
- “Play next” option when right-clicking a media item in Windows Media Player 11’s library (Windows Media Player 12 already has this by default).
- Quickly re-enable all plug-ins after a Windows Media Player crash (screenshot).
Windows Media Player Plus! supports Windows Media Player 12 on all recent releases of Windows.
