Overview for macOS audio creators
Mastering Tool Demo is a complimentary macOS utility built for people who prepare and polish audio content. It combines three processing modules engineered with Apple's AVAudioUnit framework to help you bring mixes up to broadcast and streaming loudness targets and attain a polished, professional sound.
Built-in processors
- Master Limiter — A final-stage ceiling that keeps peaks under a set threshold (for example, 0 dBFS or targets like −14 LUFS), preventing clipping and taming transient spikes so output remains within specification.
- Infinite Wheel — A continuously rotating gain control that lets you dial in minute level changes for accurate gain staging and smooth fader moves.
- Beast Equalizer — An extensive 66-band EQ paired with a relative linear spectrometer, allowing surgical tonal shaping while monitoring frequency response to retain sonic integrity after adjustments.
Benefits and typical uses
Use this toolset to:
- Achieve consistent loudness and safe peak levels required by distribution platforms.
- Fine-tune overall gain and perform precise leveling with a non-stepping fader.
- Sculpt frequency balance with a high-resolution equalizer while visually verifying spectral changes.
Free alternative recommendation
VLC media player — a no-cost, cross-platform application useful for auditioning mixes and confirming playback behavior. While not a mastering suite, VLC is an accessible companion for checking final files on various codecs and playback scenarios.
