Frequency Sound Generator

Frequency Sound Generator turns your phone or tablet into a flexible sound laboratory. You can generate tones, sweeps, multi-tone signals, and different types of noise for testing speakers, tuning audio systems, or creating soundscapes for relaxation. The app uses a user-friendly interface, runs in the background, and includes many ready-made examples so you can start immediately without building every test from scratch.

Core Generators and Sound Modes

The app includes a wide set of signal generators that cover both basic and advanced audio work:

• Tone generator for single-frequency output
• Sweep generator for scanning across a frequency range
• Multitone generator with 16 real-time channels
• White noise and pink noise generators
• Function generator for different waveform types
• Program generator for structured test sequences
• Audio file generator with multi-channel output up to 5.1
• Ultrasound generator (requires a 48 kHz or 96 kHz DAC)

Extended Precision and Control Features

Frequency Sound Generator focuses on stability and accuracy for serious testing:

• Linear or logarithmic sweeps, including musician-friendly options
• High-accuracy real-time wave engine using 64-bit IEEE 754 double precision
• Manual frequency stepping up or down in real time with smooth output (designed to avoid pops and clicks)
• Continuous looping that plays without lag or audio artifacts
• Amplitude modulation for more complex signals
• 16-track real-time multi-tone creation for layered testing
• Preset saving, so you can store your configuration and reuse it later
• Independent left/right channel volume control for precise balancing
• Configurable fade-in and fade-out times for clean starts and stops
• Channel inversion for cancellation and phase-related experiments
• A large library of pre-programmed sound tests aimed at audio professionals

Practical Uses: From Speaker Tests to Sleep Sounds

You can use the app for a wide range of real-world tasks, including:

• Running speaker tests and checking frequency response
• Fine-tuning home, car, or studio audio systems
• Creating relaxation and meditation tones
• Building noise masking sound beds
• Using pink noise to support sleep routines
• Identifying a likely tinnitus frequency by sweeping and matching pitch
• Doing a basic age-related hearing loss check
• Using a “speaker cleaner” style tone sequence to help push out water or dust from phone speakers
• Learning sound concepts through hands-on experiments

Built for Experimentation

Because the app combines multiple generators, real-time control, and reusable presets, you can set up quick tests or design complex multi-channel sessions. Whether you need a simple sine tone or a structured sweep-and-noise routine, you can build it and run it smoothly in the background.
