title: SimpleADL W3C XML schema (XSD) version: Version 1.0 date: December 2010 author: Nitin Arora (http://humaneguitarist.org) SimpleADL stands for Simple Audio Decision List. SimpleADL was devised as an XML format to be processed by a Python application called AudioRegent. Please see "http://blog.humaneguitarist.org/projects/audioregent/" for more information about SimpleADL and AudioRegent. The audio file that the audio decision list is "about". A place to embed technical metadata particular to the audio signal. Location of audio channel; establishes spatial context of child elements. Instructions: If the audio signal has one channel, use only one [channel] element with the [position] attribute having a value of "mono". If the audio signal has two channels (i.e. stereo), use only two [channel] elements with the [position] attributes having values of "left" and "right", respectively. Location of first occurrence of lowest amplitude value. Measurement of first occurrence of lowest amplitude value. Location of first occurrence of peak amplitude value, "peak of the peaks". Measurement of first occurrence of peak amplitude value, "peak of the peaks". Average power/amplitude of audio signal. Duration of the audio signal. Defined segment within the audio signal. Identifier for [region] element. Starting position, or "in" point, of a region. Length of a region. A place to notate content such as administrative notes, descriptions, transcript text, etc. using XHTML (EXtensible HyperText Markup Language). Signifies whether regions are to be outputted as separate "tracks" (value of "true") or a single outputted audio stream with the regions concatenated (value of "false"). Unit of measure; provides amplitude context for an element value. "dbfs" = decibels full scale. Unit of measure; provides temporal context for an element value.
