Open Eclipse AudioSync (.aes) files
An .aes file won't play in anything — it's encrypted. You can't brute-force it, but Eclipse can export the audio in one step. Here's the workflow, then how DepoAudio takes it from there.
What is an .aes file?
Eclipse AudioSync records the audio that travels with an Eclipse transcript as a .aes
file. It’s AES-128 encrypted and tied to its case, which is why double-clicking it does nothing
and why no converter — DepoAudio included — can read it directly. The encryption isn’t a format quirk to work
around; it’s deliberate.
The good news: you already own the key. Eclipse itself can export a plain, unencrypted copy. Once it’s a WAV, it’s ordinary audio that any tool can open.

→ WAV
Free the audio in four steps
- Open the session in Eclipse CAT — the AudioSync audio lives with its case.
- Export to WAV via File → Export Audio → WAV. This writes an unencrypted copy.
- Drop the WAV into DepoAudio. It’s detected instantly — no setup.
- Convert, split, or clean up. MP3 for sharing, FLAC for archive, or Smart Cleanup — all local.
From the WAV onward, nothing touches the network: DepoAudio makes zero calls during conversion, so the recording stays on your machine.

Common questions
What about Eclipse AudioSync (.aes) files?
.aes files are AES-128 encrypted and cannot be decoded without the Eclipse CAT software. To work around this, open Eclipse and export manually: File → Export Audio → WAV. Then drop the exported WAV into DepoAudio if you need to reformat or process it.
