About this app

🎧 Sound Frequency Analyzer is a real-time audio analysis tool that measures sound frequencies and amplitude using your Android device's microphone.

📊 Features:
• Real-time sound frequency and amplitude analysis
• Display of average frequency (Hz) and amplitude (dB)
• Graphical spectrum view with zoom for detail
• Interactive sound graph to examine specific frequencies
• Self-calibration to match your phone’s microphone characteristics
• Works as a decibel (dB) meter and frequency (Hz) analyzer

🎶 Use for Music:
Perfect for musicians and hobbyists — visualize the frequencies of instruments like piano, guitar, violin, and voice. Analyze pitch and loudness during practice, tuning, or live playing. Most instrument tones fall well within the supported range of this analyzer (up to ~4,000 Hz).

🔎 How It Works:
The app captures audio using your phone’s mic and analyzes it in real time. It shows a live graph of sound amplitude across different frequencies — giving insight into the sound environment around you.

📈 Analyze Sounds Like:
• Musical notes and tuning
• Voice and speech tones
• Room or background noise
• Basic tones and ambient sounds

🎯 Use Cases:
• Instrument tuning
• Sound level monitoring
• Audio calibration
• Educational sound analysis

Note: This version is optimized for audio up to approx. 4,000 Hz. Some high-frequency content (e.g. cymbal overtones or ultrasonic signals) may not be fully displayed, depending on your device’s microphone.

🌟 Free to use — with an optional banner ad at the bottom to support development. You can remove ads via in-app option if desired.

Ratings and reviews

Useless to isolate a specific sound like finding what is emitting a high pitch sound, it just continuously reports sounds on different frequency with a strange unit not even understandable

What even is this doing even??? I paid to get the rest described and this is it? Some random numbers next to random length lined and arbitrary dB! Start Refund @ 23 seconds post-OOBE!!!

Much better similar apps that include all tools needed to use an RTA.
