## Audio Spectrum Analyzer 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. 

You can turn on the Peak Hold to make it easier to see transient events, as well as adjust the decay rate.

Swiping with two fingers lets you adjust the brightness of the spectrum or the graticule grid overlay.

Tapping three times with two fingers will save a screenshot to your Photos.

One of several user selectable window functions can be used:
Rectangular
Hanning
Hamming
Tukey
Cosine
Lanczos
Blackman

## Audio Spectrum Analyzer Reviews in United States

### ***-- "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.
-- technomuso, 2020-01-15

### *---- "Doesn’t work"
Doesn’t work with iPhone XR.  Looks like it has t been updated in years. Not worth any money
-- cyclops8807, 2019-03-29

### *---- "stopped working after about 3 minutes"
but hey, does anyone’s design actually work nowadays?
-- scs2016, 2019-03-06

### *---- "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!
-- Wyomingrandad, 2019-02-03

### ***** "Got noise?"
Excellent tool for analyzing sound background noise, and data transmission modes. Features allow zooming in and out and peek hold.
-- Gigologene, 2019-01-30

### ***** "Just the thing..."
Intuitive, simple, powerful.  Read the FAQ, which is the user guide/manual.
-- The Great Caruso, 2019-01-15

### ***** "Excellent tool"
Great tool for analysis of audio sound.
-- Comets43, 2018-03-16

### ***** "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.
-- Pidloop, 2018-02-18

### *---- "Not good"
Very low update rate and limiyed interface, definitely not worth paying for
-- MagicalTux, 2017-12-19

### ***** "Great for mobile frequency checking"
Recommend this for novices and pros.  Great for setting up a sound room or booth.  Good Job!
