RAVENNA ASIO & Core Audio Guide 1 Introduction RAVENNA is a solution for real-time distribution of audio and other media content in IP-based network environments. It was designed primarily by a company called ALC NetworX. RAVENNA utilizes standardized network protocols and technologies and can operate in existing network infrastructures. Performance and capacity scale with the capabilities of the underlying network architecture.
RAVENNA ASIO & Core Audio Guide 2 Introduction to RAVENNA Technology Scope The information in this chapter is provided as background of the philosophy and technology behind RAVENNA. Overview RAVENNA is a technology for real-time distribution of audio and other media content in IP-based network environments. Utilizing standardized network protocols and technologies, RAVENNA can operate on existing network infrastructures.
RAVENNA ASIO & Core Audio Guide Basic Components RAVENNA Network Basic Components Example A RAVENNA system requires a carefully configured IP network, a master clock device and any number of RAVENNA enabled I/O nodes. The master clock can be either a dedicated device or any RAVENNA node capable of serving as a grandmaster. The preferred time domain reference is GPS.
RAVENNA ASIO & Core Audio Guide Streaming Unicast Unicast (one-to-one) is used in application scenarios such as an individual stream between two devices (e.g. a multi-channel stream between a console and a recorder/DAW). This uses a point-to-point connection between the sender and receiver. Since each additional receiver adds its own individual connection network traffic increases with every additional unicast stream.
RAVENNA ASIO & Core Audio Guide 3 Merging RAVENNA ASIO Driver (PC) Overview The RAVENNA ASIO Driver is intended for owners of Horus hardware using Windows 7 who wish to work in ASIO RAVENNA mode.

Latency and clicks Audible pops and clicks can occur when using some third-party audio interfaces or depending on the speed of the processor.
RAVENNA ASIO & Core Audio Guide No Playback, no I/Os There is a potential problem when changing sampling rate. (DAW cursor locked or mismatched sampling rate) In such a case ensure the DAW (Pyramix) is exited first then change the sampling rate on the RAVENNA ASIO panel before re-launching the DAW. (Pyramix) Now check that the Project sampling rate and Horus sampling rate match the RAVENNA ASIO panel sampling rate. Re-start if necessary.
RAVENNA ASIO & Core Audio Guide I/O Connection Naming & Channel Count When using the RAVENNA ASIO driver the connections enabled in Easy Connect do not display the module name or connection count in the Pyramix Mixer. For example: If the RAVENNA ASIO Panel has 48 I/Os selected a fixed count of 48 I/O channels (at 1fs) will appear in the Pyramix Mixer. The module naming will be generic. It is necessary to refer to the Easy Connect connections numbering in order to identify the I/O routing.
