Comments on Spectral Audio Analyzer for Android

★★★★★ Ian · Nov 16, 2023

Great application in Sound Anyalising and Detection were some background or Floor Noise is present during Sound Recording, the Spectral Display can give you a Visual Indication of the Interference Frequency's effecting the whole Recording, enabling the Recordings to select the Correct Amount of Filtering to eliminate Clicks/Hiss or Mechanical interference, without effecting the whole Recording.... Genuine Customer feedback, Artist and Producer Ian Donnelly, THE WIMP LABEL.

All you can wish from sound spectrum expressed in graphics. All sounds' frequency and volume scrambled into one fine to read graph.

★★★★★ Gina Harrison · Apr 12, 2022

This is a lifesaver for those being stalker and hard or hearing. Thanks and bless you!

★☆☆☆☆ A Google user · Mar 8, 2019

Use Spectroid instead. This app just wants you to get the Pro version, and it can't even use unprocessed audio from your mic

★☆☆☆☆ Ali · Jul 5, 2026

It's not a spectrum analyzer for audio files, but rather for what your phone mic is capturing. Useless.

★★☆☆☆ Kelly Norman · Oct 6, 2021

The fact this loser developer charges over 4 bucks for an app that does what now if I can't plug in my sdr dongle to it to listen to police radio and ham then he's nothing but a greedy low life who just wants people's money loser.

★★☆☆☆ Aren · Jul 2, 2026

8khz cut limits the free version a lot. Otherwise, just about ok if you don't care about high frequencies over 8k
