The Audio tab in Composer's Settings window provides configuration options for audio monitoring, metering, and preview functionality.

VU Meter Settings
Enable VU-meters
Activates the VU (Volume Unit) meters throughout the application, displaying audio level indicators for audio sources and outputs.
Default number of audio channels
Sets the default number of audio channels used when creating new audio sources or configurations.
Peak level meter max age
Controls how long peak level indicators remain visible on the VU meters before decaying.
| Display Value | Enum Member | Internal Value |
|---|---|---|
| 1 second | OneSeconds | 1 |
| 5 seconds | FiveSeconds | 5 |
| 10 seconds | TenSeconds | 10 |
| 30 seconds | ThirtySeconds | 30 |
| 60 seconds | SixtySeconds | 60 |
| 5 minutes | FiveMinutes | 300 |
| 10 minutes | TenMinutes | 600 |
| Infinite | Infinite | int.MaxValue |
Peak level meter min value
Sets the minimum decibel (dB) value displayed on the peak level meters. Lower values provide a wider dynamic range display.
| Enum Member | Internal Value |
|---|---|
| db120 | -120 |
| db96 | -96 |
| db72 | -72 |
| db60 | -60 |
| db48 | -48 |
| db24 | -24 |
Require audio device on application startup
Requires an audio device to be present and available when Composer starts.
Use RMS VU-meters
Switches from peak metering to RMS (Root Mean Square) metering, which provides a more accurate representation of perceived loudness.
RMS Window size (ms)
Specifies the time window (in milliseconds) used for RMS calculations. Only applies when "Use RMS VU-meters" is enabled.
| Display Value | Enum Member | Internal Value |
|---|---|---|
| 100 ms | OneHundredMs | 100 |
| 200 ms | TwoHundredMs | 200 |
| 300 ms | ThreeHundredMs | 300 |
| 400 ms | FourHundredMs | 400 |
| 500 ms | FiveHundredMs | 500 |
| 600 ms | SixHundredMs | 600 |
| 1000 ms | OneThousandMs | 1000 |
Show audio tab (deprecated)
Controls the visibility of an audio tab in the application interface. This setting is deprecated and may be removed in future versions.
Audio Preview Settings
Audio preview
Selects the audio backend technology used for audio preview playback.
| Display Value | Enum Member | Description |
|---|---|---|
| Autoselect | Auto | Automatically selects the best available backend (ASIO → WASAPI Exclusive → WASAPI Shared) |
| ASIO (requires ASIO driver) | Asio | Lowest latency; requires compatible ASIO driver |
| WASAPI Exclusive mode | WasapiExclusive | Low latency; takes exclusive control of the audio device |
| WASAPI Shared mode (default) | WasapiShared | Allows other applications to use the audio device simultaneously |
Latency (ms, 5-2000ms)
Sets the target latency for audio preview playback. Lower values reduce delay but may cause audio glitches on slower systems.
Buffer length (ms, 5-2000ms)
Configures the audio buffer size for preview playback. Larger buffers provide more stable output but increase latency.
Notes
- Some settings may require restarting Composer to take effect.
