Clarifications

1 This is a meaningful short name. A full description would be in a <Description> component.

2 This is a SEDRIS sound URN, in the form urn:x-sedris:<DNAS>:sound=<SN> where:
<DNAS> is domain name authority name string, and
<SN> is a scoped sound resource name string.

3 This is the length of the sound clip in seconds.

4 This is the number of samples per second. For example, a standard CD has a sampling of 44.1 kHz, which would be a sampling rate of 44100.

5 This is also called “sample size” or “quantization”; for example, a standard CD has 16 bits per sample.

6 Note that 1 = mono, 2 = stereo (CDs can be recorded with 4 channels).

7 This identifies the encoding scheme (such as MULAW, ALAW, ACE, ADPCM, CELP, LPC) and compression scheme (CODEC) used, if any.

8 If provided, this specifies either - information about the events and/or source data used in constructing the given instance, or - lack of knowledge about lineage.

Example(s)

  • A sound, such as a siren that can be used by different models such as ambulances, fire engines, or police vehicles.
