gives real frequency info!

Other cheap similar apps only make pretty pictures. This one gives you labels and you can tap at a spot on the chart to see the corresponding frequency. Highly useful for basic audio analysis.

Don't bother with version 1

Very little functionality in this app - it's as if the author wanted to do an rta app, got the mechanics working and then published with no features - there is no calibration, no pause, no save

Disappointed

This is absoloutely worthless. It does a refresh about every 20 second with a graph that is meaningless - little or no relationship to audio input. There are zero options. I want my money back! I ended up gettting a chromatic tuner with SA for less money and it works!

Works!

Imagine an analyzer for 2 bucks! Can't vouch for accuracy but seems to be spot on.

Did not work

installed on Mac M2 Air, and it did nothing! How do I uninstall it and get my money back?

Very clean App.

Developer has used the "keep it simple stupid," (KISS) development mode. Easy simple intuative interface. Works well on M1 Mac mini. With a wide variety of USB microphones, from the cheap low end, to pro level mics. Vaery basic, but very well worth the money. Would be nice to vary the FFT bin levels. CUDOS to the develolper!

Very useful

This app will be very nice to have for when I tune rooms for sound systems. I would have given 5 if I could increase the db level to monitor the frequencies. I need at least 90db

Useful app, but...

This is a very useful app, but i wish you were able to hold the iPad in portrait view since the mic on the iPad is on the top... The app doesn't auto-rotate.

Functional

Though perhaps not feature-laden, this app is certainly more than a toy. Has four different types of windowing, multiple scales and manually adjustable cursors. Definitely a good deal for $2

Suggestions

I like the app,nicely done, but I would really like to be able to specify a number of samples and then average the amplitudes at each frequency ... This would enable me to pick out dominant frequencies and get rid of the random noise.

Description

bs-spectrum is a simple FFT spectrum analyzer application. This application calculates FFT (Fast Fourier Transform) of the sound which is recorded by the iPad & iPhone's internal mic. The calculated data is displayed as graph.
