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.
Speccy also supports the most analysis window functions of any similar app:
• Hann/Hanning
• Hamming
• Sine/Cosine
• Rectangular
• Triangular
• Welch
• Blackman
• Blackman-Harris
• Flat Top
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 dialing 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 repository here: https://github.com/spikything/speccy/tree/master/source/assets/xml
