Overview
Synchronize your team's voice communications with demo playback to hear callouts and strategies in context. This feature is exclusive to Private Demos.
Requirements
Private Demos
Audio sync only works with demos in your Private Demos section, either uploaded manually or synced via HLTV team linking
100% Private
All audio files and demos you upload are completely private - only team members can access them
[ 02 ]
Sync Methods
There are three ways to synchronize audio with your demos, each with different benefits.
Available Methods
Audio Files (MP3/WAV)
Upload recorded team comms from TeamSpeak or Discord bots like Craig. Best quality with no game audio overlap.
YouTube Videos
Faster sync without file upload, but includes game audio from the video alongside the demo audio.
Team Recording
Sync team recordings to get both the 2D map view and all player camera perspectives.
For recording team comms, we recommend TeamSpeak's built-in recording or the Craig bot for Discord.

Audio Upload
To upload audio files, open the demo and click the headphone icon. From there, select the language of the audio you're uploading.
Language selection is important because CS2.CAM uses AI to generate subtitles for the first 5 minutes of audio. These subtitles help with synchronization later.

Manual Sync
After uploading audio, you'll need to synchronize it with the demo. The manual method gives you precise control over the timing.
Sync Controls
Audio Waves
The timeline shows audio waveforms as a visual reference for when people are talking
Time Controls
Use the buttons to shift the audio forward or backward: +10s, +1s, +0.1s and -10s, -1s, -0.1s
Fine Adjustment
Make small adjustments until the audio matches perfectly with the action on screen
Pro tip: Have someone say a keyword at a specific moment during the game (like when the round starts or bomb is planted) to make synchronization easier.
