# XApuProcessType

Defines the processing types that will be performed by XAPU client(s).

## Syntax

```cpp theme={null}
enum class XApuProcessType  : uint32_t  
{  
    None = 0,  
    DecodeOpus = 1,  
    DecodeConvertOpus = 2,  
    ConvertPCM = 3,  
}  
```

## Constants

| Constant          | Description                                                                                                                                                                                                      |
| ----------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| None              | Invalid process type.                                                                                                                                                                                            |
| DecodeOpus        | Decode Opus stream(s). Input stream(s) can be CELT, SILK or Hybrid. Only Mono and Stereo streams of 2.5 (CELT only), 5 (CELT only), 10 or 20 milliseconds packet durations at 48000 sample rate are supported.   |
| DecodeConvertOpus | Decode and Sample rate Convert of Opus stream(s). The input stream can be CELT, SILK or Hybrid. Only Mono and Stereo streams of 2.5 (CELT only), 5 (CELT only), 10 or 20 milliseconds packet durations at 48000. |
| ConvertPCM        | Sample rate Convert of uncompressed PCM float (32-bit), mono and stereo stream(s) at 48000 hz sample rate.                                                                                                       |
