In person: put a phone face up in the middle of the table, bottom edge clear, plugged into power. Use the built-in voice recorder on a compressed setting. Have everyone say their name before you start.

Online: use the recording built into Discord, Zoom, Meet or Teams, then export the audio track on its own. Ask everyone to use headphones, which is the single biggest quality difference on a call.

Recording an in-person game

Use the phone, not a recorder

Every phone made in the last decade has a voice recorder that will handle four hours in a single file. On iPhone it is Voice Memos; on Android it is usually Recorder or Voice Recorder. A dedicated device is a nice upgrade and completely unnecessary to start.

Do a ten-second test and play it back before session one. Finding out the mic was covered is much cheaper at the start of the night than at the end of it.

Where to put it

Face up, in the middle, with the bottom edge clear, because that is where the mic usually is. Not under a character sheet, not in a dice tray, not in somebody's lap. Distance to the people talking matters more than anything else you can control.

Plug it in. Four hours of recording with the screen occasionally waking will flatten a battery, and a recording that stops at the three-hour mark tends to stop right before the interesting part.

Distance beats equipment. A phone in the middle of the table picks up every seat. The same phone at one end, or under a character sheet, loses whoever is furthest away for the whole night.

What to tell the table

Two things, once, at the start:

A phone in the middle of the table beats a good microphone at the end of it.

Recording an online game

Every major platform can record without a plugin. In each case you want the audio at the end, not the video.

Discord

Discord has no native recording for regular voice channels, so most groups use a recording bot. Whichever you use, check two things: that it records each speaker on their own track if it can, which is the best possible input for speaker labelling, and that it is allowed on the server before session night rather than during it.

Zoom, Google Meet, Microsoft Teams

All three record to the cloud or locally depending on your plan, and all three produce a video file by default. That is fine; you just export the audio track before you do anything else with it. Zoom in particular will often give you an .m4a alongside the video without being asked.

The one thing that matters on a call

Headphones. Without them, everyone's speakers feed back into their own microphone, and the recording ends up with every voice layered faintly over every other voice. Echo cancellation hides this while you are playing and cannot remove it from the file afterwards.

Settings: smaller is better than you think

There is a strong instinct to record at the highest quality available. For speech it is the wrong instinct, and it costs you twice: a slower upload and a bigger file to move around, for a transcript that is no better.

Transcription discards everything outside the range of a human voice regardless of what you give it. Mono, compressed is the right setting. On iPhone that is Settings โ†’ Voice Memos โ†’ Audio Quality โ†’ Compressed, set before you record. A four-hour session recorded that way is a fraction of the size of the lossless version and transcribes identically.

A four-hour session, by setting Lossless / WAV 2 GB and up 128 kbps stereo 230 MB 64 kbps mono 115 MB 32 kbps mono 58 MB
All four transcribe the same. Speech carries almost no information above the voice range, so the bottom setting costs you nothing and uploads roughly forty times faster than the top one.

Things that quietly ruin a recording

What to do with it afterwards

The recording is not the point. Nobody re-listens to four hours of their own session. The point is the twenty lines of notes buried in it: what happened, who was there, what got promised, what everyone will have forgotten by next week.

You can pull those out by hand, and plenty of DMs do, by scrubbing through the file with a notepad open. It works and it takes about an hour. The alternative is to have something transcribe it and write the recap for you, which is the entire reason this site exists.

Scrivorn Upload the recording and it writes the recap, updates your campaign wiki, and gives your players a portal to read between games.
