Rescue a recording that's too quiet

Authentic audio is the material; speed and text make it teachable.

The situationThe recording is barely audible — a distant mic, a timid speaker, a phone across the room. The recording lives in Zencastr.

The chain

1

Get the recording out of Zencastr

Per-guest audio tracks appear in the dashboard after upload completes; download each track (WAV/MP3). Wait for the post-call upload to finish before grabbing tracks — partial files are a classic gotcha.

2

Normalize the loudness

EBU loudness normalization brings it to the standard voice target without clipping.

3

Then transcribe or share

The normalized file is listenable and transcribes with better odds on marginal audio.

What you end up with: A usable recording instead of an inaudible one.
