Description
π§ Sound Frequency Analyzer is a real-time audio analysis tool that measures sound frequencies and amplitude using your Android device's microphone.
π 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
πΆ 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).
π 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.
π Analyze Sounds Like: • Musical notes and tuning • Voice and speech tones • Room or background noise • Basic tones and ambient sounds
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.
π Free to use — with an optional banner ad at the bottom to support development. You can remove ads via in-app option if desired.

Happy annoying people with it It is fun to make people angry and not know it's Me who's making the sound

This application has enlightened me to a world from a different perspective. You then are faced with the ethical issues that come with one's own values and principles. Me personally do respect one's RIGHT TO A PRIVATE CONVERSATION. There is also an addictive side to these devices. However when the natural world is out there to be discovered it's great.

Cool app This is great. Shows all the overtones in the voice tone. Brilliant! Thanks

Perfect for my need. Shows frequency a d decibels in real time
Tested on guitar string tuning. Hz indications toggled between two set frequencies regardless of how slightly I adjusted string tension. Not accurate to true frequency tuning, at least for musicians.

Meh! Slow, sluggish response. Awful and the ads slow it down. Db and freq average was a cool addition, but this app is slow to show respone.

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