Thank you for your feedback!

This node merges two incoming audio together and outputs it as a stream. For the node to work correctly, it needs to be used in a streaming project.

Parameters:
none

Inputs

Audio:
Accepts Streaming and Batch audio from a single channel.

Events:

name	description	known nodes that generate this event
Start of TTS Fragment	Signals the start of a TTS segment.	TTS Http
Speech Started	Signals the start of speech in realtime.	Vad
End of TTS Fragment	Signals the start of a TTS segment.	TTS Http
Speech Ended	Signals the end of speech in realtime.	Vad

Outputs

Audio:
Streams one-channel audio from the output connection.

Events:
None

Remarks
Working Principle

The node outputs the streaming audio instantaneously no matter what.
Whenever an audio batch is received from a TTS node or a VAD node, the audio batch will be kept in a queue.
If the batch audio queue is empty, the output stream is the same as the input.
If the batch audio queue is not empty, the incoming streaming audio will be merged with the first audio in queue and streamed in the incoming rate.

Overflow

If the merged audio is too loud for the audio format, the node will automatically normalize the output stream.
