Each fragment contain at least some audible data. Works on batch audio. ### Supported Sample Rates - 8 kHz - 16 kHz ### Parameters none ### Inputs #### Audio Accepts audio from a single channel. #### Events none ### Outputs #### Audio Audio fragments are sent to output #### Events | name | description | | --- | --- | | [Start of Segment](/v1/docs/events#start-of-segment) | Raised once at the beginning of each audio fragment. | | [End of Segment](/v1/docs/events#end-of-segment) | Raised once at the end of each audio fragment. | ### Remarks This node toasts the audio output write actions for each segment in between start-of-segment and end-of-segment events. As an example for an audio data with 3 audio segments, the flow is as follows (the order is well defined): segment-1: send "Start of Segment" event segment-1: write the audio data of this segment to output segment-1: send "End of Segment" event segment-2: send "Start of Segment" event segment-2: write the audio data of this segment to output segment-2: send "End of Segment" event segment-3: send "Start of Segment" event segment-3: write the audio data of this segment to output segment-3: send "End of Segment" event #### Project Structure A minimal project with Audio Segmenter can be built as such:

Important Note Make sure that both the `Audio` output and the `Event` output is connected to the receiving nodes. Otherwise, the following nodes will not know when the audio starts and ends. #### Supported flow types Batch ### Release History ****v1.0.0**** - Introduced Node.
