Speccy – Spectrum Analyser

I created an Audio Spectrum Analyser app which has proved very popular (over 100k downloads and counting). Turn your phone into a professional spectrum analysis tool and break into safes – um, please don’t use it for that 😉

How does it work?

The app uses an FFT algorithm to analyse sound and has some features not found in similar apps. Check it out!

What can it be used for?

There are many uses for spectrum analyzers, such as:

    Assessing environmental noise for health and safety
    Sound checking speaker setups, PA systems and in-car stereos
    • Identifying audio signals obscured to the human ear by noise
    • Testing the microphone on your device
    • Comparing the quality of different brands of headphones
    • Testing signal generators
    • Tuning musical instruments
    • Measuring audio signals just outside human perception. As people age over 20 years, their aural perception range drops well below 21 kHz

Speccy has also been used to find gas leaks and even hunt ghosts, apparently!

How to use it

For mixing or calibrating audio equipment, watch these handy videos or see the articles below, have a look at this article on using spectrum analyzers, this one on using spectrum analyzers for mixing, or watch these useful videos:

I occasionally give away a few copies of Speccy, when there are promo codes available. Here’s a random promo code from the database, which someone may or may not have used already 🙂
