SoundApp
SoundApp is a legacy audio player and converter utility for macOS that supports a wide variety of sound file formats including WAV, AIFF, MPEG, QuickTime, and others. It allows files to be dragged and dropped for playback or conversion, supports playlists for batch processing, and includes shuffle and repeat modes. The app was distributed as a PowerPC native binary for Classic Mac OS in the early 2000s and was widely used by Mac users who needed to work with diverse audio formats without requiring separate codecs or additional software.

1 suggestionSoundApp has been abandoned for over 25 years — the last release (version 2.7.3) was in November 2000, and there is no native Apple Silicon build. The Intel build still launches under Rosetta 2 today, but Apple is removing Rosetta in macOS 28 (September 2028), so this app will stop working entirely on that release. For audio playback, macOS's built-in Music app, VLC (free, open source, natively supports Apple Silicon), or Audirvana are modern alternatives. For audio conversion, a command-line tool like FFmpeg (free, scriptable, runs natively on Apple Silicon) or a dedicated converter like XLD (also free and Apple Silicon native) will handle any format SoundApp once supported. If you have audio files or playlists you want to preserve, export them to a standard format like MP3 or AIFF now — those formats are supported by all modern Mac audio tools.
