This node contains information about a sound used in the system. Audio nodes are used for interactive sound scrubbing, playback with sound, etc., and can be created through the "sound" command. An audio node contains a path to a sound file in AIFF or AIFF-C format, and a start time for the sound.

channels, duration, endFrame, filename, frameCount, mute, offset, order, sampleRate, silence, sourceEnd, sourceStart, track, trackState

Long name (short name)TypeDefaultFlags
channels (c) integer0outputconnectable
The number of channels in the sound file
duration (du) time::zerooutputconnectable
The length of the sound file in frames
endFrame (ef) time::zerooutputinputconnectablestorable
The end time of the audio clip
filename (f) stringNULLoutputinputconnectablestorable
The path name to the actual sound file.
frameCount (fc) integer0outputconnectable
The number of sound frames in the sound file. A sound frame is a discrete sound sample
mute (mu) bool0outputinputconnectablestorable
Whether the sound is muted. Note: animating this attribute is not supported
offset (o) time::zerooutputinputconnectablestorable
The time the sound file begins
order (r) integer1outputinputconnectablestorablehidden
Playback order
sampleRate (sr) integer0outputconnectable
The sample rate of the sound file
silence (si) time::zerooutputinputconnectablestorable
Amount of silence before playing the sound (this is useful when trying to manage the audio clip)
sourceEnd (se) time::zerooutputinputconnectablestorable
The frame from the original source file at which this sound actually stops playing (used for trimming the end of sound playback)
sourceStart (ss) time::zerooutputinputconnectablestorable
The frame from the original source file at which this sound actually begins playing (used for trimming the beginning of sound playback)
track (tk) integer1outputinputconnectablestorablehidden
Track number. This flag was obsoleted and was only present for 2010 compatibility, however, I need it for the track naming feature.
trackState (ts) short0outputinputconnectablestorable
Flag bits for the track state. Current mask values are: 1: when set means that all the audio clips on the track are locked 2: when set means that all the audio clips on the track are soloed 4: when set means that all the audio clips on the track are muted 8: when set means that another track is soloed, so this track acts as if it is muted 16: when set means that the audio clip is muted, used by tools that work on a shot/shot basis, not via tracks
