Multichannel audio Stream over Ethernet/LAN

• Project ID:

  782360

• Project Type:

  Fixed

• Budget:

  $250-$750 USD
  

Project Description:

On a local 10/100 base Network I need to send 8 Channels of uncompressed audio 96k-24bits provided from a Analog Devices ADAU1401A in TDM format (serial I2S stream of 8 Channel of audio 96k 32bits) from one point to an other point and receive it on an other Analog Devices ADAU1401A.

The project should:

- Provide source code in C with all necessary files to successful implement in the MCU and and for future improvements
- Schematic diagram ( analogue circuitry, ADC, Sigma DSP, DAC are 90% done )
- Need to design MCU, Ethernet PHY, LCD and push buttons
- Use a MCU with a Ethernet Layer 3 Stack to send / recive a TDM8 serial stream of 8 Channel of audio 96k 24bits from / to the ADAU1401A DSP's
- RTCP run on top of UDP
- The MCU should have all necessary GPIO pins to connect a LCD Display, push-buttons to navigate in menus for configuration purposes of the TCP/IP Network connection and to basic configurations of ADAU1401A (like volume up and down per Channel), SPI ports to controll the ADC and DAC chip's and logic outputs CD4066 cmos switch.
- Synchronization
- Provide lowest latency possible
- Components should not be BGA Package

Skills required:

C Programming, Electronics, Microcontroller, PCB Layout
