`RegulateChunkSizes`¶

Fix up chunk size irregularities in streaming data using a buffer.

This node maintains a running estimate of the average number of samples that it receives on each update (e.g., 135 samples), and adjusts the amount of data that it outputs on each update to be this quantity of samples. The node maintains a buffer of configurable length to be able to absorb "hitches" in the input pipeline. As a result, the node outputs a very regular stream of samples even if the input processing chain has very irregular latency characteristics. One use of this node is to drive smooth-scrolling plots and other visualizations that shall be smoothly updating. Version 1.0.0

Ports/Properties¶

`data`¶

Data to process.

verbose name: Data
default value: None
port type: DataPort
value type: Packet (can be None)
data direction: INOUT

`buffer_length`¶

Buffer length. This is the length of the buffer to absorb hitches, in seconds.

verbose name: Buffer Length (Seconds)
default value: 1
port type: FloatPort
value type: float (can be None)

`reset_on_gap`¶

Reset the state if a gap is encountered that is longer than this. In seconds.

verbose name: Reset On Gap
default value: 5
port type: FloatPort
value type: float (can be None)

`also_reset_buffer`¶

Also reset buffer on gap.

verbose name: Also Reset Buffer
default value: False
port type: BoolPort
value type: bool (can be None)

`set_breakpoint`¶

Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.

verbose name: Set Breakpoint (Debug Only)
default value: False
port type: BoolPort
value type: bool (can be None)

`metadata`¶

User-definable meta-data associated with the node. Usually reserved for technical purposes.

verbose name: Metadata
default value: {}
port type: DictPort
value type: dict (can be None)
