This is an encoder (yellow) element. It encodes the audio according to RFC 6716 (Opus audio codec).
| ! | Opus |
|
Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the IETF. XXX See here for more details on the format. |
| E | Cautious configuration recommended |
| The Opus element includes many options that require an in-depth understanding of audio encoding to correctly configure. Caution is advised when configuring these options. For most applications it is enough to set the desired bitrate and leave the other options untouched. |
| Element | Description |
|---|---|
| Nominal bitrate | Information field: Shows the current bitrate when the PIPE is active. |
| Audio type |
Dropdown: Sets the audio profile for optmized compression.
|
| Encoded audio bandwidth |
Dropdown: Sets the audio bandwidth.
|
| Bitrate | Sets the bitrate in kbit/s. Note that you can use the selector to the right (⇒) to select one of the common bitrates. |
| Bitrate type |
Dropdown: Selects constant or variable bitrate encoding.
|
| Discontinuous transmission (DTX) | Toggles whether bitrate should be saved during silence ("On"). |
| Encoder complexity | Sets encoding complexity. The higher the value, the slower the encoding process but the better the compression. |
| Frame size | Dropdown: Selects the frame size. |
| Inband FEC | Toggles Inband Forward Error Correction “On” or “Off”. |
| Expected package loss | (Only if Inband FEC is toggled “On”) Sets the expected packet loss in %. The less stable your network is, the higher this value should be. The higher the value, the more data is added through Forward Error Correction. |
| Maximum payload size |
