Tone Generator
Tone Generator is a desktop audio utility for macOS that produces pure sine, square, sawtooth and triangle waveforms at user-specified frequencies. The app is used by audio engineers for testing equipment and acoustics, by musicians for tuning and reference pitches, and by students studying sound waves and audio theory. It allows precise frequency entry, volume control and waveform selection through a simple interface. The generated tones can be played directly through speakers or headphones for real-time listening.
AI Recommendation
1 suggestionWe found very limited public information about the native Apple Silicon status of Tone Generator from NCH Software. The search results point primarily to an online browser-based tone generator, not the desktop app. To determine whether a native Apple Silicon build is available or planned, we recommend contacting NCH Software directly via their support page to ask whether they have released or plan to release a Universal Binary build before macOS 28 ships in September 2028. If NCH Software has not yet shipped a native version and you cannot get a clear commitment on timing, consider the free online alternative at onlinetonegenerator.com — it offers similar waveform generation and frequency control through any modern web browser, requires no installation, and will continue to work on future macOS versions without dependency on Rosetta 2. For professional audio testing, SoX (a command-line tool installable via Homebrew) also runs natively on Apple Silicon and provides more advanced frequency and waveform generation features.
