Description

Spectrum Pad turns your iPad, iPhone, or iPod Touch into an audio spectrum analyzer. Frequencies up to 20 kHz can be displayed.
You can control the displayed frequency span, as well as the FFT size, from 1024 to 262144 bins.
A logarithmic display of the entire 10 Hz to 20 kHz frequency range is available, and the graph fill mode can be turned on and off, as well as the display of up to five frequency markers.
Filtering (averaging) can be applied to the spectrum, to smooth out variations.

Audio Spectrum Analyzer Reviews

Needs averaging

Very useful, but it would be so much better if it could do a running average of the spectrums. This would help to pull signals out of the noise floor.

Doesn’t work

Doesn’t work with iPhone XR. Looks like it has t been updated in years. Not worth any money

stopped working after about 3 minutes

but hey, does anyone’s design actually work nowadays?

This app is sold with false pretenses!

Buyer beware! This is listed under Spectrum Remote. I wanted to control our TV using my phone. This does not do that. I asked for a defund and was told NO!

Got noise?

Excellent tool for analyzing sound background noise, and data transmission modes. Features allow zooming in and out and peek hold.

Just the thing...

Intuitive, simple, powerful. Read the FAQ, which is the user guide/manual.

Excellent tool

Great tool for analysis of audio sound.

Accurate on iPad mini

Happy with this app. Frequency markers on peaks very handy. Checked against 500 and 600 Hz tones on WWV and both were within 0.1 Hz. Recommended.

Not good

Very low update rate and limiyed interface, definitely not worth paying for

Great for mobile frequency checking

Recommend this for novices and pros. Great for setting up a sound room or booth. Good Job!
