User Reviews

Based on user feedback, Audio Function Generator PRO is praised for its clear UI and expansive feature set, including presets and tunings, enabling versatile applications from music production to healing and equipment testing. Users repeatedly cite ease of use, depth of options, and strong value. However, several reviews flag stability issues (crashes, stuck frequencies, settings not saving) and some UI responsiveness concerns (unresponsive controls, clunky GUI). A number of users also request more advanced features (logarithmic sweeps, panning, phase shifts, longer hold times) in future updates.

Pros

Clear, easy-to-use interface with a broad range of frequencies and presets.
Rich feature set: 48 customizable presets, BPM modulation, non-standard tunings (432 Hz, 528 Hz), Solfeggio tones, white noise, and flexible sweeps.
Very versatile for many use cases: testing audio gear, tuning instruments, binaural beats, healing, and music production.
High-quality engineering and strong value: well-built and reasonably priced; regarded as a top frequency generator on the market.

Cons

Stability and reliability issues reported (crashes on certain devices, frequencies sticking, and settings not persisting).
UI responsiveness concerns (some reviewers report unresponsive buttons and a clunky GUI).
Users request more advanced features (logarithmic sweeps/scale, panning, phase shifting, longer hold times) for future updates.
