If your recording software crashes, immediately stop all devices and disconnect them from your recording chain to prevent corruption. This means shutting down your computer, unplugging your recorder and any external preamps and audio interfaces, and pulling the plugs on your mics and headphone distribution. Yes, it's painful to stop the train mid-conversation, but it's a necessary step to salvage what you have.

Before trying to salvage the recording, review the crash's impact and assess the remaining audio. If the software crash happened right before a critical segment, you may not have enough intact audio to work with. In this case, it's better to admit your limitations and offer to continue the conversation from the last point of recovery. Transparency about what happened and what's salvageable can actually build rapport with your guest.

If the affected section isn't critical, you can still salvage it. Look for any recovered wave files or audio snippets, even if they're partially corrupted. If you've been recording a backup file on a separate machine or storage device, you might be able to recover some or all of the lost audio from those.
