Preferences Panel

The preferences panel is a common element of all Omniverse KIT based apps and provides a long list of settings that are applicable to the current app. Because of this, not all apps have all of the categories or options listed on this page. Note that all settings here apply to the app as a whole and are not stored with individual USD stages.

Audio

There are some application preferences that can help to control the behavior of audio output globally in Omniverse Omniverse Create. These preferences affect all USD stages loaded in Omniverse Omniverse Create. These settings are not stored as part of the USD stage. The app preferences window can be opened by going to the “Edit” menu and choosing “Preferences”. The audio preferences can be found by selecting “Audio” in the sections list on the left.

Audio Devices

Input and Output device preferences.

Option

Result

Output Device

Displays a drop-down box containing the names of all audio output devices connected to the system. This may be used to select the desired device for output in Omniverse Omniverse Create. This affects output for the main USD stage and all UI audio. Once a device is selected from the list, the “Apply” button must be pushed to accept the change. Changing both this setting and the speaker configuration below will cause the output of all open audio contexts to be changed. If the state of devices attached to the system has changed recently (ie: a new device was connected or a device was disconnected from the system), the “Refresh” button can be used to collect the new device list. By default, the system’s default output device will be chosen.

If the selected device is disconnected from the system between launches of Omniverse Omniverse Create or the device list changes between launches, the previously selected device will attempt to be found first on the next launch. If it is still attached to the system, it will be used. If it could not be found in the device list, the system’s default output device will be used instead.

Input Device

Displays a drop-down box containing the names of all audio input devices connected to the system. This may be used to select the desired device to use for recording in Omniverse Omniverse Create. This affects input for all USD stages. Once a device is selected from the list, the “Apply” button must be pushed to accept the change. The input device is unaffected by the “Speaker Configuration” setting. If the state of devices attached to the system has changed recently (ie: a new device was connected or a device was disconnected from the system), the “Refresh” button can be used to collect the new device list. By default, the system’s default input device will be chosen.

If the selected device is disconnected from the system between launches of Omniverse Omniverse Create or the device list changes between launches, the previously selected device will attempt to be found first on the next launch. If it is still attached to the system, it will be used. If it could not be found in the device list, the system’s default output device will be used instead.

Speaker Configuration

Sets the speaker configuration to use for output. All configurations are supported regardless of the device’s capabilities (ie: a 5.1 configuration is still supported on a stereo device). In the case the output mode is not directly supported by the selected device, the final output of the audio system will be down-mixed to the device’s preferred configuration. As much of the original stream as is possible will be preserved in the down-mixed output.

If the “auto-detect” configuration is selected, the output will try to match the device’s preferred format. Note that this could result in extra processing requirements on some devices due to the larger number of speaker channels.

The “Apply” button must be pushed (or Omniverse Omniverse Create relaunched) after changing this setting for this to take effect. | Refreshes the device lists for audio input and output. If a new device is connected to the system or an existing device is removed, pushing this button will refresh the device lists to reflect the new device sets for both input and output.

Note: this button may disappear in the future in favour of auto-detecting system device changes.

Apply

Applies all changes to the audio input and output device selections. This will have no effect if none of the options have changed. However, if a device is in use at the time (ie: actively recording audio or actively playing audio in a stage), this could result in a brief interruption in audio. It is best to ensure that all audio recording and playback has been stopped before pushing this button.

Audio Parameters

Option

Result

Auto Stream Threshold

Defines the asset size at which the audio system will decide to stream a compressed audio asset instead of decompress it into memory. This threshold is expressed in kilobytes. If this is set to zero the auto-streaming feature will be disabled. If this is set to any larger value, any compressed audio asset with a decompressed size larger than this threshold will be streamed from the original compressed object instead of being decompressed. The benefit of this is lower memory usage and faster asset loading. However, streaming sounds does require slightly more processing time. The default value is 0KB.

Audio Player Parameters

Option

Result

Auto Stream Threshold

Defines the asset size at which the audio player will decompress a compressed asset on-the-fly during playback instead of decompressing it into memory on load. This has the benefit of using less memory and allowing playback to start sooner (for large assets at least). This threshold is expressed in kilobytes. If set to zero, all assets will be decompressed before playing. If set to a non-zero value, any compressed asset with a decompressed size larger than this value will be decompressed as it plays. This defaults to 256KiB.

Close Audio Player on Stop

Determines whether the audio player will close on its own once the first playback of a sound completes. This is useful when previewing large numbers of audio assets from the content browser. If this option is left unchecked, the audio player window will remain open after playback completes. This defaults to unchecked.

Volume Levels

Adjust volume properties of sounds.

Option

Result

Master Volume

Defines the master volume level for all audio output in Omniverse Omniverse Create. All other volume levels are effectively multiplied by this volume level to get the final overall volume. Setting this to 0.0 will result in silence (though audio data will still be fully processed). Setting this to 1.0 will be full volume. The volume level changes linearly across this range. This defaults to 1.0.

USD Volume

Defines the volume level to be used by all audio for the USD stage audio output. This affects all spatial and non-spatial sounds. Setting this to 0.0 will result in silence (though audio data will still be fully processed). Setting this to 1.0 will be full volume. The volume level changes linearly across this range. This defaults to 1.0.

Spatial Voice Volume

Defines the volume level to be used for all spatial sounds in the USD stage. This volume level is effectively multiplied by the “USD Volume” level setting as well before output to get the final volume level for spatial sounds. Setting this to 0.0 will result in silence (though audio data will still be fully processed). Setting this to 1.0 will be full volume. The volume level changes linearly across this range. This defaults to 1.0.

Non-spatial Voice Volume

Defines the volume level to be used for all non-spatial sounds in the USD stage. This volume level is effectively multiplied by the “USD Volume” level setting as well before output to get the final volume level for non-spatial sounds. Setting this to 0.0 will result in silence (though audio data will still be fully processed). Setting this to 1.0 will be full volume. The volume level changes linearly across this range. This defaults to 1.0.

UI Audio Volume

Defines the volume level to be used for all UI audio sounds in Omniverse Omniverse Create. This affects all sounds that go through the omni.Create.uiaudio python interface. Setting this to 0.0 will result in silence (though audio data will still be fully processed). Setting this to 1.0 will be full volume. The volume level changes linearly across this range. This defaults to 1.0.

Debug

Stream Dump Filename

Defines the filename to be used when dumping the USD stage audio output to file. This will be written out in WAVE file format regardless of the extension on the filename. The channel count and data format will match the current output device’s selected channel count and format. This file will be written to disk as audio is played and will always try to remain within a few milliseconds of audio away from what is playing on the device (as close as possible).

The output file must be on a local file volume. Sending output to an omniverse location is not supported. Once stream dumping is enabled, the output file will be created and it will be written to as new audio data is produced. The output will continue until stream dumping is disabled or Omniverse Omniverse Create is exited. The default value for this setting is an empty string.

Note that as long as this feature is left enabled, data will continue to be written to the output file. Since this is written as uncompressed data, this file will tend to grow rather quickly. For example, a 48KHz stereo floating point signal will write approximately 22MB per minute. For this reason, the “Enable Stream Dump” setting is not persistent in Omniverse Create user configuration. It will always be off when Omniverse Omniverse Create launches.

Enable Stream Dump

Defines whether stream dumping is currently enabled. As soon as this is enabled and a valid filename is selected in “Stream Dump Filename”, writing to the output file will begin. Stream dumping will continue until this setting is disabled or Omniverse Omniverse Create is exited. This setting does not persist in Omniverse Omniverse Create’s user configuration. It will always be disabled on a fresh launch of Omniverse Omniverse Create.
