Audio.Compress¶
| Name | Mandatory | Description | Default | Type |
|---|---|---|---|---|
⬅️ Input |
Accepts audio data as an Audio chunk, containing the sample rate, number of samples, number of channels, and the audio samples. Opus supports sample rates of 8, 12, 16, 24, or 48 kHz. | Audio |
||
Output ➡️ |
Outputs the compressed audio data as a sequence of Binary chunks, each containing an Opus-encoded packet. | [Bytes] |
||
Bitrate |
No | The target bitrate in bits per second (bps). Valid values range from 500 to 512000. Use 0 for automatic bitrate management. | 64000 |
IntVar(Int) |
Application |
No | The type of audio being encoded. Options are: "voip" (optimize for speech), "audio" (optimize for general audio), or "lowdelay" (optimize for low latency). | audio |
StringVar(String) |
Complexity |
No | The encoding complexity, from 0 (lowest) to 10 (highest). Higher values use more CPU but may provide better quality. | 10 |
IntVar(Int) |
FrameSize |
No | The frame size in frames (samples). Must be one of the valid Opus frame sizes for the given sample rate. Common values are 120, 240, 480, 960, 1920, or 2880 frames at 48kHz. | 960 |
IntVar(Int) |
UseMultistream |
No | Enable if the source is multistream encoded. | false |
BoolVar(Bool) |
Compresses audio data using the Opus codec. Opus is designed for interactive speech and audio transmission over the Internet, providing high-quality compression with low latency. This shard takes raw audio data and outputs compressed Opus packets as a sequence of byte chunks.
