MacAmp is an open-source audio player for macOS, designed as a reproduction of Winamp 2.95. The application is built using Swift, SwiftUI, and AppKit, and it supports both Apple Silicon and Intel architectures. It requires macOS 14 or later to function.
The player supports various audio formats, including MP3, AAC, M4A, FLAC, WAV, AIFF, Ogg Vorbis, Opus, MP2, AU, and MIDI. With an optional FFmpeg plugin, it also handles MKV, WebM, AVI, WMV, WMA, APE, and WavPack. Users can import Winamp 2.x skins in .wsz format or as folders.
The interface includes a ten-band equalizer, playlist, and main window that snap together magnetically. The developer utilized AI agents to write the majority of the code, providing them with documentation, project structure rules, and original Winamp screenshots to ensure visual and functional consistency.
The application is distributed under the MIT license and is free to use. It does not include cloud-based media libraries or subscription services. The developer notes that the app is not signed with a Developer ID to allow for dynamic file icon changes, requiring users to bypass Gatekeeper upon the first launch.
