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.
