The chain

1

Get the recording out of Field recorders (SD-card)

Recordings are WAV (often broadcast-WAV) on the SD card, organized by folder/date; copy off via card reader. Multi-hour WAVs are huge — compress or extract parts before any upload.

2

Cut the silence

Dead air is pure waste — remove it first.

3

Compress what remains

Opus mono on the tightened audio: the minimum bytes that keep every word.

What you end up with: The smallest file that still says everything.

For field reporters: Street noise gets a normalization pass first.
