Introduction

The Intel Synchronized Audio Toolkit consists of several pieces of sample code that wrap ALSA timing primitives. It contains building blocks for a time aware mixer and capture module. It uses the OpenAVB time sync daemon for the 802.1AS protocol. There are several Python scripts that use this example code creating a simple demo that measures distance between two devices

Prerequisites

- **libsndfile** development package/source - **Doxygen** - **pdxlatex** - usually part of **TeX Live** package

Building

Build sample applications

Checkout the Open-AVB submodule:

git submodule update --init

In the support directory run:

make

This generates the time sync daemon and helper application for the ranging demo that finds a "chirp" signal given an audio file In the top level directory run:

make

Build the documentation

In the top level directory run:

make docs

Produces documentation.pdf in the top level directory.

Running the demo

In the support/RangingDemo directory run:

./RangingDemo <-p|-r> -d \ -i \

One machine should use the -p flag to play audio, the other machine should use the -r flag, to record audio.

Example applications

@subpage play_at

@subpage record_at

@subpage sys_to_net_time

@subpage net_to_sys_time
