The aim of this project was to build an MP3/WAV player using just a FPGA, some RAM & a stereo DAC. The project consists of a custom 32-bit soft core processor running at just under 60MHz which decodes the MP3 algorithm in software with no hardware acceleration apart from a single cycle Xilinx multiplier unit.

This is my first AVR based hobby project and the most successful one compared to my all previous stuff. I am 100% satisfied with this work.. Few months ago, I tried to make a wav player using a PIC16F877A. It worked anyway, but the audio quality was not so good for higher sampling rate because that chip doens’t have enough ram and thus I couldn’t implement a good data buffer. But when I bought an atmega32 microcontroller, the first thing came to my mind is to make a good wav player…Now, I have completed my work and the audio quality is really amazing…

NOW I can say that, my wav player IS ABLE TO PLAY 8 BIT MONO/STEREO with maximum bitrate of 1300kbps for mono and 1600kbps for stereo … ie it can play an 8 bit mono wav of sampling frequency upto 160KHz and stereo upto 96KHz without any noise or trouble!!!!! (at OSC 16.450MHz).

Radio Arduino – uses Adafruit WaveShield!… [via]

What it is really doing is playing 24 music tracks that I preloaded onto an SD card in WAV format. There are also 10 tuning noises tracks that get played when the tuner is turned.

Because this is the first time I did this I had a lot of help. Firstly the chaps and chapesses at Hackspace have been very supportive in teaching me how to use and Arduino, particularly Adrian McEwan and Oomlout. Also Jingle Joe who supervised my soldering of the Wave Shield, Brox who helped me decipher the ancient mysteries of FAT16 and Esme who helped dismantle the original radio… PS I did do some of it myself!

This project is a Wav Audio Player based on PIC18F2550, it is able to play RIFF WAVE files and display some file information on the N6610 LCD. It plays the audio file via the PIC’s PWM with a simple RC filter on the output pin. The data is read by a SD card. Check it out.

This project is a Mini-STM32 SD/MMC WAV (RIFF-WAVE-LPCM format) Audio Player with Spectrum Display. Project files are available for download.

In this article Bernard Klinc demonstrates audio playback using the dsPIC on a simple breadboard layout with a free code library for SD card access from Microchip. This project is mostly around the Microchip MDDFS library (Memory Disk Drive File System). It’s a neat pile of C source code that can manage a FAT12, FAT16 or FAT32 file system and interface to a SD or CF memory card or an IDE hard drive. But best of all its free!
