Overview of Speccy Spectrum Analyzer
Speccy is an audio spectrum analysis tool that visualizes the distribution of sound frequencies, both audible and inaudible, detected through your phone's microphone.
Transform your phone into a spectrum analyzer. It uses Fast Fourier Transform signal processing and is the only app on the market that also lets you export audio snapshot data to the clipboard (for plotting in Excel, etc.).
Features of Speccy Spectrum Analyzer
• Assess sound for health and safety
• Check locations with PA systems and car stereos
• Identify audio signals that are inaudible to the human ear
• Test the microphone on your device
• Test signal generators
• Tune musical instruments
• Measure audio signals just beyond human perception. As people age past 20, their hearing range drops significantly below 21 kHz.
Another use case is helping you secure a safe or combination lock: use the spectrum analyzer with your device acoustically integrated with a safe dial - for mechanical dials only. As you slowly turn the dial, you can "hear" when a sound falls into place, as the sound spectrum will be slightly different from a "normal" tick (depending on the build quality of the safe or combination lock). With this technique, you can detect when you hit the correct number and start dialing in the other direction. Please only do this with a safe you own - we are not responsible for misuse.
