CS2 Voice Comms Calculator

Set <code>tv_listen_voice_indices</code> and <code>tv_listen_voice_indices_h</code> in the console (to the same number) before playing the demo. The number is a bitmask of the spectator slots you want to hear. The easiest way is to upload the demo here - it fills the players automatically and gives you the exact commands to copy.

Because Valve matchmaking and Premier demos do not record player voice at all - there is simply no voice data in the file, so no command can play it back. Voice is recorded in FACEIT, ESEA and other server (SourceTV) demos. If you want to review comms, use a FACEIT demo.

Upload the demo so each player shows their team, then click "All T" or "All CT" to select just that side (or tick individual players). Copy the commands and you will only hear that team. To isolate one toxic player, tick only their slot.

It is the CS2 console variable that controls which players' voice you hear while watching a demo. Its value is a 32-bit bitmask: bit 0 is spectator slot 1, bit 1 is slot 2, and so on. Set it to -1 to hear everyone, or use this calculator to build the exact number for the players you want.

<code>tv_listen_voice_indices</code> covers spectator slots 1-32 and <code>tv_listen_voice_indices_h</code> covers the high slots 33-64 (used in larger lobbies / SourceTV). For a normal 5v5 you only need the first, but setting both to the same value is harmless and most reliable, so this tool always outputs both.

Spectator slots are assigned from the player entity order in the demo, which can shift between playback sessions. Uploading the demo here reads the actual slot for each player, so you do not have to re-check with spec_player after every reload.

Yes - FACEIT demos record voice, so the commands work. FACEIT CS2 demos are .dem.zst files; you can upload one directly here and it is decompressed and parsed for you. Matchmaking and Premier demos contain no voice.

Yes. Upload your CS2 <code>.dem</code> (or a FACEIT <code>.dem.zst</code>) and the tool reads the demo and fills each slot with the correct player name and team, so you skip the tedious <code>spec_player 1..16</code> loop entirely. Then tick the players you want and copy the commands.

The real console command is <code>tv_listen_voice_indices</code> - singular "voice". Some guides write "voices" by mistake, but that command does not exist in CS2 and does nothing.

It is sent to our server only to read the player slot list, then deleted automatically within minutes - the same short-lived handling as our video tools. Nothing is stored or shared. Prefer not to upload? The manual entry mode runs entirely in your browser.
