He brings up how it can be used for discovering EVP's which is interesting if a person believe in ghosts or entities that are not perceived easily by our senses...
But what got me erect was that it tickled my dreams of becoming an international spy or maybe a fearless diamond thief?
Yapps it can be used to crack safes!
When reading this went to the closest bank and asked if it was possible to try the app on their main safe but alas they denied me and security was called in... So yesterday had to sit in a small cell with fifteen scary looking dudes with tears tattoed all over their faces...
But it was okay after awhile as we got more and more drunk on toilet wine and we have now exchanged social information and it will hopefully lead me to go and crack a safe in the end with one of those hardened criminals???
In either case wish that there was a safe in my possession to try it out on.

Turn your phone into a Spectrum Analyzer. Speccy is an Audio Spectrum Analysis tool, which visualizes the spread of sound frequencies in the audible (and inaudible) spectrum, detected through your device's microphone, using Fast Fourier Transform signal processing. It supports the most languages of any similar app (English, Spanish, Portuguese, Polish, German, Italian, Russian, French and Thai) and is the only app which also lets you export audio snapshot data to the clipboard (for plotting in Excel, etc). Speccy has a wide variety of uses, such as:
• Assessing environmental noise for health and safety
• Sound checking venues 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 been used successfully to find gas leaks, test ultrasonic pest control equipment and has even used by EVP enthusiasts to try and detect ghosts! You can also learn about using spectrum analyzer's here.
The app could also help you get into a safe with a mechanical combination lock for which you have forgotten the code: With your device acoustically coupled to the safe's dial, turn the dial slowly, you can 'hear' when a tumbler drops in, because the spectrum of the sound will be very slightly different than turning one 'normal' tick (depending on the build quality of the safe). Using this technique you can detect when you hit a correct number and start dialling the other way.
Please only do this with a safe or combination lock you own - we accept no liability for misuse. If you'd like to help contribute translations in your language, see the github repo here: https://github.com/spikything/speccy/tree/master/source/assets/xml
