Real-Time Audio Spectrum Analyzer

Real-time audio spectrum analyzer & generator is proposed to design as a test instrument (with 1-2 Hz accuracy), which has following objective:

●Signal Analyzer: Measure the spectral contents of the analog signals in audio frequency band. Analog signal captured from 3.5 mm stereo input are processed inside DSP kit & measurement results are sent over UART to a Python based display.

● Signal Generation: In this mode, it can be used as signal generator to generate the analog signal through 3.5 mm output jack.
