The board has very compact dimensions with the basic ports to be mounted on the rear side of the devices, it occupies only the minimum space on the connector side. For the controls and ports on the front or top panels, the board offers internal connectors in proper layout and orientation.

AUDIFIED Core Board

Ports

 

Rear side

  • Gbit Ethernet
  • USB Host
  • USB 2 Device
  • TOSLINK or ADAT in and out
  • S/PDIF in and out

Inside the device

  • 4 Audified bus connectors, each providing 4 balanced analog audio inputs, power, control signals for analog gain control and other functions
  • 4 Audified bus connectors, each providing 4 balanced analog audio outputs, power, control signals for analog gain control and other functions
  • 2 additional Audified bus connectors, each providing control signals for displays, buttons etc.
  • 2 Audified X-Bus extension ports, each allowing to connect an extra AD/DA with up to 16 in or 16 out analog ports, control or cascading circuits
  • UART, SPI, I2C and other standard peripherals
  • Extension socket for mikroE standard. This socket allows to connect huge portfolio of peripheral extensions produced by mikroE, or create custom boards with the same socket. The socket provides standard control signals. This socked is mounted for development purposes, Audified provides a bridge to standard signals such as I2C from this board. Customers may use the socket e.g. for simply adding switches.

One purpose boards

Final products for consumer audio, installations and music industry have many functionalities, various sets of inputs and outputs, various control elements and various processing algorithms. The development of such a complex system takes years and could be very expensive.

Building box approach

Audified ASCore board and the supplementary ecosystem offers easier creation of the audio systems. Select modules from a building box, with one system bus for audio and control signals. Design of very customized systems is effective and fast.

Software options

Our mission: The hardware without excellent firmware and control software would not make sense.

  • The hardware board runs Audified software for the ARM processor (Linux, RTOS, BM) and software for the SHARC.
  • A top-class library of algorithms, proven in Audified effect SW.
  • The firmware for the DSP processors is open, allowing to incorporate custom DSP code written in C/C++.
  • Audified offers a control protocol, allowing full external control from iOS, Android, MacOS and Windows.
  • Audified provides a plug-in framework allowing the integration of the hardware equipped with our board into DAW systems.
  • In some of our applications, a web server runs on the board, so the system communicates over internet.
  • The board may even run an audio host application connecting to an external audio interface via USB host connector (as an extension to the internal audio system).
  • The board offers several pins and signals to control a variety of peripherals. Audified provides a code library required for communication with these peripherals.

Examples of available algorithms

  • MP3 recorder with automatic publishing of files to a cloud server
  • Various dynamics processors
  • Parametric and graphic EQ
  • Valve simulation preamps
  • Transistor simulation preamps
  • Speaker modeling, speaker characteristics compensation, low latency, IR or better technology
  • Complete guitar processing
  • Feedback elimination
  • Multichannel microphone processing for speech, auto mixing

Multichannel routing

The control software allows to have an overview of all components and signal routes.

Processing elements

The user interface allows to edit parameters of the elements processing the signal.
