BeatDrop Music Visualizer vs MultiPatch

BeatDrop Music Visualizer is a Windows desktop visualizer built around a custom MilkDrop2 engine. It responds to speaker or microphone audio, including sound from media players, and includes more than 10,000 presets alongside compatibility with MilkDrop.milk presets. Visual tools include custom waves and shapes, beat detection controls, transitions, shader caching, and drag-and-drop preset loading. Presets can react to mouse and keyboard input, while shaders can use FFT and waveform data as well as system time and date. It also supports synchronized LRC lyrics, a timestamp editor, and a local lyrics cache; matching lyrics are fetched from LRCLIB. Spout can route visuals to supported apps including OBS, Resolume, TouchDesigner, and Unity. On Windows 10 version 1809 or later, system media controls provide now-playing details, playback position, and seeking. The normal build supports Windows 8.1, 10, and 11; an OldOS build covers Vista through Windows 11. The free, open-source software costs nothing. Requirements include 2 GB RAM, a WASAPI-compatible sound card, and a compatible GPU.

MultiPatch is a free macOS application for applying and creating file patches. It applies BPS, IPS, UPS, PPF, XDelta, BSDiff, and RUP (Ninja2) patches, and creates BPS, IPS, PPF, XDelta, and BSDiff patches. To apply one, users can select a patch file or drag it onto the application window, then choose the target file and where to save the result. The application identifies the format from the patch file extension, so that extension must be correct. BPS creation offers Linear and Delta modes: Delta patches are usually smaller, but take longer and require more memory. Creating UPS and Ninja2 patches is not supported. The maker says patching is built into the application rather than handled by external tools. Version 2.0 requires macOS 10.9 or later; older releases are available for Mac OS X 10.4 through 10.8. A separate basic command-line version can apply or create patches for scripts or terminal use. The application is GPL-licensed, while the bundled patching libraries have their own licenses.
