In order to get a better dynamic range, values are scaled up as follows (I'm calling the spectrum values 'amplitudes' here as well). Click the Calibrate button and enter play mode to start fine-tuning ...

Analog audio analyzers use analog hardware to generate signals and analog filters to measure them. By contrast, digital audio analyzers use digital signal processing (DSP) algorithms to both generate ...

That's why I'm asking questions before I start this project. :-) Currently I am trying to plan out how I'm going to build an LED Audio Spectrum Analyzer. I'm hoping to use an IC to split an audio ...

You can use mmwave sensor, there are two frequency-based sensor 77GHz (AWR1642 or AWR1843) and 60GHz (IWR6843) which you can use for this purpose. However to measure distance b/w the sensor you need ...

Abstract: A Fiber Bragg Grating sensor based Contact Microphone (FBGCM ... When attached to the surface of an audio device or the human throat, they pick up vibrations generated by the sound produced.
