What is Frequency Sound Generator MOD APK?
Frequency Sound Generator MOD APK is a powerful and precise audio signal generation app developed by WeDoAndroidApps for Android. It turns your phone or tablet into a fully capable sound laboratory — letting you generate pure tones, frequency sweeps, white and pink noise, ultrasound, multi-channel test signals, and structured audio sequences for speaker testing, audio system tuning, relaxation, sleep, hearing checks, and hands-on sound experimentation.
The official app locks its Pro features behind an in-app purchase. The Frequency Sound Generator MOD APK activates every Pro tool completely for free. All debug information is removed, the full signal generator suite is unlocked, and the complete professional audio laboratory experience is available as a free download on Android 6.0 and above.

MOD Features of Frequency Sound Generator MOD APK
Here is everything unlocked and improved in this MOD version:
- Pro Activated – Every Pro feature that requires a paid upgrade in the official app is fully accessible at absolutely no cost from the moment you open the app.
- Debug Information Removed – All debug code and information has been stripped from the build for a cleaner, more stable, and faster-running app on all supported Android devices.
- Tone Generator – Generate pure single-frequency tones at any frequency you choose with precise control over amplitude and waveform type for basic and advanced audio testing.
- Sweep Generator (Linear and Logarithmic) – Smoothly scan across a wide frequency range using either linear or logarithmic sweep modes, including musician-friendly sweep options designed for natural-sounding audio transitions.
- 16-Channel Real-Time Multitone Generator – Create and control up to 16 simultaneous audio channels in real time, making it ideal for complex multi-frequency speaker tests, frequency response analysis, and layered sound design.
- White Noise Generator – Produce flat-spectrum white noise for speaker burn-in, audio masking, sleep aid, tinnitus relief, and acoustic measurement reference signals.
- Pink Noise Generator – Generate pink noise with its natural 1/f frequency weighting, widely used by audio engineers for speaker equalization, room acoustics testing, and relaxation soundscapes.
- Function Generator (Multiple Waveforms) – Output sine, square, triangle, and sawtooth waveforms for electronics testing, audio education, and signal analysis experiments.
- Program Generator – Build and run structured test sequences with multiple signal stages, durations, and transitions for systematic speaker or audio system evaluation.
- Audio File Generator (Up to 5.1 Multi-Channel Output) – Generate and export audio test files with up to 5.1 surround sound channel configurations for home theater and professional studio testing.
- Ultrasound Generator – Produce frequencies beyond normal human hearing range for specialized testing applications — requires a 48 kHz or 96 kHz compatible DAC on your Android device.
- 64-Bit IEEE 754 Double Precision Wave Engine – The app uses a high-accuracy real-time audio engine built on 64-bit double precision floating point calculations for technically reliable and artifact-free signal output.
- Manual Real-Time Frequency Stepping – Step frequency up or down manually during live playback with smooth transitions specifically engineered to eliminate pops, clicks, and audio artifacts between steps.
- Amplitude Modulation – Apply amplitude modulation to base signals for more complex waveform shaping and advanced audio experimentation on any Android device.
- Independent Left and Right Channel Volume Control – Set separate volume levels for the left and right audio channels independently for precise stereo balance control during testing.
- Configurable Fade-In and Fade-Out – Set custom fade-in and fade-out durations for clean, professional signal starts and stops without abrupt audio transients.
- Channel Inversion – Invert one channel relative to the other for phase cancellation experiments, speaker polarity testing, and acoustics research.
- Preset Saving and Loading – Save your complete signal generator configuration as a named preset and reload it instantly for repeatable test sessions without rebuilding every setting from scratch.
- Continuous Looping – Play any generated signal in a seamless continuous loop without lag, drift, or audio artifacts for extended testing and background sound applications.
- Large Pre-Programmed Test Library – Access a built-in library of ready-made audio test examples so you can start running professional-grade speaker and system tests immediately without any manual setup.
- Background Playback – The app continues running and generating audio in the background while you use other apps on your Android device.
- Speaker Cleaner Function – Run a dedicated tone sequence designed to help push dust, debris, or water out of phone and tablet speakers for a quick and effective speaker maintenance routine.
- CPU Arch Supported: armeabi-v7a, arm64-v8a – Compatible with a wide range of modern and older Android hardware.
