Summary

Sound Forge Audio Tools is an Android app that serves as a mobile audio laboratory for sound engineers, musicians, students, and audio enthusiasts. It offers a comprehensive collection of offline tools for audio analysis and signal generation within a professional user interface.

Features

• dB meter: Real-time sound level measurement via the microphone
• Tone generator: Generates sine, square, and test tones with precise frequency control
• Noise generator: Generates white, pink, brown, and power-law noise
• FFT analyzer: Frequency spectrum analysis of audio files or recordings
• 2D FFT/spectrogram: Time-frequency visualization with playback tracking
• Band listening: Isolation and monitoring of specific frequency bands

The app also offers advanced digital signal processing functions such as Fast Fourier Transform (FFT), Short-Time Fourier Transform (STFT), Power Spectral Density (PSD) analysis, and band-limited signal reconstruction.

Special Features

All audio processing is performed entirely locally on the device without data transmission or upload to the cloud. No user account is required for operation, and the app does not listen in the background. This ensures privacy and security of the audio files.

Intended Users

The app is aimed at sound engineers, musicians, producers, students of digital signal processing, researchers, hobbyists, and anyone interested in sound and audio signals. It is suitable for audio testing, calibration, music production, sound design, signal processing education, as well as acoustic analyses and experiments.

Disclaimer

The measurements and analyses are intended for educational and experimental purposes. For safety-critical or professional measurements, the use of calibrated and certified devices is recommended.
