I made an audio spectrum analyzer project using ARM Cortex-M3 (STM32F013C8) and LED matrix 8x8. A spectrum analyzer tracking generator operates by providing a sinusoidal output to the input of the spectrum analyzer. Tags for this video: rainbowduino RGB LED spectrum analyzer. Does anyone have a tested circuit? Look here: Christmas Project - Audio Analyser A Digital, real time Audio Frequency Spectrum Analyzer for audio devices" The Digital, real-time Audio Spectrum analyzer circuit for audio devices can be. Free delivery and returns on eligible orders. The circuit will take line level output from most any audio source, and operates on 12V DC. Together with Touchstone software you now have an RF diagnostic tool unmatched in price and performance. g 20Hz to 20K Hz. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced.
