Audio recorder

Connect an audio bus to Audio, set File pattern, and enable Record while the process is executing. Disable Record to close the recording; Filename emits the actual saved path after a nonempty recording is closed.

The recorder writes 16-bit WAV audio at the engine sample rate, preserving the input channel count. Keep the channel count stable during a take: changing it reopens the file. This is an audio recorder, not a recorder for device values.

Use %t in File pattern for the current UTC date/time (colons are replaced with underscores), or %n for an available numbered filename. For example, use a writable path ending in take-%n.wav to keep separate takes. Number selection checks the resolved destination directory. A fixed filename can be overwritten on a later recording.

For parameter recording and replay, use the CSV recorder.
