Description

Sound Spectrum Analyzer meters sound noise level (SPL - amplitude in decibel) and detects sound frequency spectrum in real time (RTA) using FFT.

The analyzer is very easy to use and offers a lot of useful features: high RTA refreshing rate and frequency spectrum resolution, adjustable sound noise level (SPL) amplitude scale (up to 150 decibels), RTA peak hold function, flat reference line, local peak frequency...

Sound analyzer can detect audio on 3 separate channels. User can later compare noise level (SPL - dB) and frequency spectrum charts between the channels.

It also includes a frequency generator with noise option, which helps to analyze the frequency response of audio system.

Audio Input/output can be adjusted to Internal, AUX or Bluetooth. However, all I/O options and combinations do not work on all devices.

Sound frequency analyzer can be accurately calibrated for each frequency band separately.

Comments on Sound Spectrum Analyzer for Android

★★★★☆ J. Pang · Nov 25, 2025

This has been really helpful to identify the strength of ambient boise, particularly in the VLF region. I wish I could isolate just VLF and ELF, as I can hear down to 14 Hz (but apparently, most humans cannot). However, for the money, it's hard to beat.

★★★★★ Lee.R McClain · Nov 21, 2025

Using a frequency generator and very capable speakers, checked the accuracy! Not bad, accuracy is great on my cell phone. App seems to function better than most, and seems to be very accurate! EQ easy to translate, one area could be improved with lower 15hrz-45000hrz would be the ideal upgrade! Otherwise, a great app! Very happy with this app! Lee.

★★★★☆ Stay Awake · Jan 4, 2026

Simple and nice app! Could use something like "lingering bars" feature to keep showing bars for a bit longer if bars are jumping too fast

★★★★★ Christie Stratton · Jan 17, 2026

Successfully capturing criminal evidence with this app. Thank you.

★★★★★ Aditya Dixit · Jan 20, 2026

Had some bassy lower frequency noise in my home. This app showed that noise with frequency. Relived that the sound is not just in my ears.

★★★★★ LightHouseAstro - Team · Nov 14, 2025

Good app for what it does for free. Thanks need quickly to check a frequency range.

WARNING ASKS FOR PERMISSIONS BUT DOESN'T SPECIFY! Click on anything and ads pop-up.

★☆☆☆☆ Dave Gearhart · Jan 15, 2026

The ads are way overboard, and it's difficult to get off of the add screen just to get back to the app. No good!

★☆☆☆☆ Einssv Z · Feb 2, 2026

Can't open without sending your info to who knows who. Trash
