3.0 out of 5
Don't bother with version 1

Very little functionality in bismarkbsspectrum - 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!

Did not work

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

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... bismarkbsspectrum doesn't auto-rotate.

Functional

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

Very useful

bismarkbsspectrum 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!

I do medium voltage switchgear maintenance and repair in my job (13.2KV down to 480V). My partner thought that he heard an air leak in the gear one day, which is a sign of arcing. That range is gone in my hearing, so I used bismarkbsspectrum with my iPhone5 on the main 13.2KV breaker and took a screen shot of it, which showed a hard spike at around 10KHz. We singled up the plant and shut down that feeder the following weekend and pulled out the main breaker for maintenance... We found evidence of arcing inside the arc chutes. We cleaned, lubed, and tested the breaker and put it back into service. Afterwards, I ran bismarkbsspectrum again as before, and took a another screenshot (over-layed) on the first one.... this showed the spike was absent now. We used this comparison graph to quantify our results to upper management, which validated the expense of a weekend shutdown. Great app!

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!

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.

Works!

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