# Audio

Exaplay 3 supports professional audio output through ASIO and PortAudio, with per-clip mixing and multi-channel routing.

## Audio Drivers

| Driver                 | Use case                                                |
| ---------------------- | ------------------------------------------------------- |
| **ASIO**               | Professional audio interfaces with low latency (< 5 ms) |
| **PortAudio / WASAPI** | Standard Windows audio, any sound card                  |

Configure the driver in **Config → Audio Settings** (see [Audio Settings](/v3/configuration/audio-settings.md)).

## Per-Clip Volume

Each clip has an independent volume control in the Inspector (in dB). Clips are mixed in software before being sent to the audio driver.

## Master Volume

The master volume fader in the Transport bar affects all audio simultaneously. Changes are ramped smoothly to avoid clicks.

## Audio Routing

On ASIO devices with multiple output channels:

1. Open **Config → Audio Settings**.
2. Assign clips or screen groups to specific output channel pairs.
3. Each assignment is saved in the project file.

## Timecode Audio (LTC)

Linear Timecode (LTC) can be received on any audio input channel and used to synchronise playback. See [Timecode & ArtNet Sync](/v3/features/timecode-artnet.md) for setup details.
