$ demodocus -a AUDIO -s SYNCMAP [OPTIONS]
description:

The sync map file can be in JSON or SSV/SSVH format (auto-detected).
optional arguments:
-h, --help show this help message and exit
-a AUDIO, --audio AUDIO
path to the audio file
-c, --continuous keep going (default: False)
-d DURATION, --duration DURATION
play audio for max DURATION seconds (default: 2)
-i INCREMENT, --increment INCREMENT
play audio every INCREMENT fragments (default: 1)
-s SYNCMAP, --syncmap SYNCMAP
path to the sync map file
-v, --version print version and exit
-w WAIT, --wait WAIT wait WAIT seconds before playing the next fragment
(default: 0)
examples:
$ demodocus -a audio.mp3 -s syncmap.json
Check audio.mp3 against syncmap.json with default parameters (2 seconds, all fragments)
$ demodocus -a audio.mp3 -s syncmap.ssv
As above, but the sync map file has SSV format
$ demodocus -a audio.mp3 -s syncmap.json -d 1
Play each fragment for max 1 second
$ demodocus -a audio.mp3 -s syncmap.json -d 3 -i 5
Play every 5 fragments, for max 3 seconds each
$ demodocus -a audio.mp3 -s syncmap.json -d 3 -i 5 -w 0.5
Pause for 0.5 seconds before playing next fragment
$ demodocus -a audio.mp3 -s syncmap.json -c -i 5 -d 1.5 -w 0.5
