Digital, real-time Audio Spectrum analyzer circuit for audio devices is presented in this project. This is a professional, professional, professional, professional, professional, professional. The Digital Real-time Audio Frequency Spectrum Analyzer can display the distribution of the audio signal energy to 20 specific frequency bands, using DSPtechnology. It uses fast Fourier transform (FFT). The resulting Fourier transform results are displayed in 20 bars. 20 x 20 LED display. The unit supports four display-modes.
Spectrum analyzers . An audio spectrum analyzer is an audio spectrum analyzer . Many modern audio devices, such as amplifiers, audio-equalizers, audio mixers, and audio players .on LCD, CRT or LED display. The spectrogram does not contain any audio effects during playback, recording or during any tonal adjustment (bass, treble, mid frequencies adjustment or adaptive equalization).
A Digital Audio Spectrum analyzer real-time circuit for audio devices is presented in this project. This is a dsPIC30F6012A , which is a property for this project. The DSP engine, the 12-bit A / D converter, the timer3 timer, 42 I / O ports and the large internal data memory. A quad of the MCP6022 op-amps for anti-aliasing filtering and gain.
Digital signal processing, Fast Fourier transform, frequency spectrum, Hamming window, real-time and frequency response.
The Digital, real-time Audio Spectrum Analyzer. It is an analog audio signal as input. It uses a DSP. It computes the distribution of the audio signal. Everything is done in real time. Author: George Adamidis
