Spectrum analyzers are employed in most of the modern signal processing systems for measuring the distribution of signal energy in frequency. An audio spectrum analyzer is used for measurements in the audible frequency spectrum (from 0 to 20000 Hz) and can be a very powerful tool for keeping a studio well tuned. A Digital, real-time […]
The aim of this project was to add remote-control convenience to the hi-fi preamp without compromising sound quality. It replacing the existing volume control with high-quality optical rotary encoder controlled by PIC 16F877. The project has 7 input sources and 5.1 surround sound.
This Audio Spectrum Monitor project use SG12232C graphic LCD to display an audio wave forms in real-time like a digital oscilloscope. It also features a FFT spectrum analysis too. This can also be applied to radio frequency band. As main processor, the project equipped with Microcontroller AVR ATmega8. These are some wave forms that can […]
This is a Surround Processor Project with the digital delay method created by Chan. This audio processor only uses general purpose ICs that easy to find. The type of this Surround Processor is generating the surround effect with processing two channels of stereo source. Most of those are generates the surround effect with separates reverberations […]
