PIC Microcontroller Synthesizer Audio Electronics …

    This project is based on the dsPIC 33FJ64GP802 microcontroller with 23LC1024 1Mbit / 128KB serial RAM for storage. DsPIC includes a 12-bit ADC and a 16-bit DAC. The first sampling is done at 12-bit resolution and 32KHz, but after that, the entire internal process is 16-bit, and the final output is actually 16-bit / 32KHz. 12-bit / 32 KHz is typical for the 1980’s rack …

    Re:Digital Direct Synthesis, does it suitable using dsPIC and MCP4911 SPI DAC? Saturday, March 05, 2011 4:18 PM ( permalink ) 3 (1) There's no way you'll get 20 channels with 10MHz max frequency out of a dsPIC + SPI. For just one channel at 10MHz max frequency you'd need to write the DAC at 20MHz, and considering the dsPIC has a max instruction ...

Advice on Programming PIC Chip for Audio Synthesis and ...

    When processing audio signals you need two things, speed and lots of memory. High quality sound uses sampling rates of 44.1kHz and higher. At 40kHz sample rate you have 25μs in between samples to process the data. Thus you need a controller chip that is optimized for DSP. A music clip 3 minutes long will take up 3 x 60 x 44100 samples = 8MB.

Digital synthesizer - Wikipedia

    https://en.wikipedia.org/wiki/Digital_synthesizer
    By the end of 1977 New England Digital (NED) released the Synclavier, the first commercial synthesizer to use purely digital sound generation and also the world's first commercial FM synthesizer.. Released in 1979, the Casio VL-1 was the first low budget digital synthesizer, selling for $69.95. Yamaha eventually commercialized their FM synthesis technology and released the …
