Introduction Our final project is a NES-style chiptune player that changes its playback tempo in response to heart rate measurements from the user. The chiptune player successfully generates four individual channels: pulse, triangle, noise, and delta modulation. After audio mixing through a hardware circuit, the resulting mono signal sounds as intended, with no waveform clipping […]

A DIY ATTiny44 based guitar preamp+effector. All the audio processing is done digitally on-board. So it is definitely not a HiFi system, but something you can definitely have fun programming. You can program the audio properties in Arduino IDE and create mobile apps that talk to the module for remotely controlling the effects. This instructable

audiogetradix4 is a simple library you can use to interface with a ac audio input. It reads data from an ADC pin and returns the RMS value of the input using DFT Radix-4 algorithm. The discrete Fourier transform (DFT) converts a finite list of equally-spaced samples of a function into the list of coefficients of

The circuit presented here demonstrates how to generate Audible Frequency from an AVR Microcontroller. The output of Microcontroller is always digital so to generate audible sound at the outset first it needs to be converted into Analog. A DAC (Digital to Analog Converter) is used for this purpose. Microcontroller generates sine wave of Audible Frequency

Our ECE 4760 final project was an audio spectrum analyzer that would display a histogram-style visualization of an audio signal. We were able to successfully display the frequency spectrum content of an audio signal in real-time using a black and white histogram visualization with bins arranged from left to right corresponding to low to high

Most car audio sound systems and radios won’t have ultra-high fidelity sound, thumping bass, or lots of extra features like MP3 player inputs. Also, while they may emphasize one area of sound, like bass or treble, they may be missing the overall picture. And that’s why buying a new stereo system (or even simply car
