## Description

**Frequency Sound Generator** is an all-in-one audio toolkit for creating, testing and exploring sound. Generate single or multiple frequencies with sine, square, triangle and sawtooth waveforms, use musical note presets, binaural beats, DTMF tones, SFX, sweeps, metronome tools and bass or subwoofer tests.

Play up to 15 oscillators or sweep oscillators simultaneously, apply vibrato, tremolo, ring modulation and pulse width modulation, and create white, pink, brown, blue, violet or grey noise. The app supports background playback, animated waveform visualization, decimal frequency input and exporting generated sounds to audio files. It can be used for music, instrument tuning, speaker testing, sound experiments, relaxation and hearing exploration.

## Review summary

Frequency Sound Generator is highly valued for its audio quality and ease of use, with many reviews praising its sound, tuning options, and learning curve. The main concerns center on monetization: users note trial-based access and a paid Pro option (rather than a simple free app), plus recurring upsell to premium features. Overall sentiment is positive, but pricing and upgrade prompts are the most mentioned drawbacks.

### Pros

- Excellent sound quality with smooth transitions, tuning features, and strong output (bass boost).
- Easy to learn and user-friendly, offering a good learning curve and positive experience.
- Widely praised by users with phrases like excellent, amazing, and the best frequency generator.
- Pricing options include a free trial and a one-time Pro payment to remove ads, avoiding a subscription.

### Cons

- Pricing can be confusing or perceived as not truly free due to trials and required upgrade to Pro.
- Upsell to Pro/premium subscription is frequent, which some users feel disrupts the experience and monetizes the app.
