# Configuration Reference

> InitParams, AudioParams, LanguageConfig, and JitterParams

## `InitParams` — passed to `Initialize()`

| Field          | Type                     | Description                                                      |
| -------------- | ------------------------ | ---------------------------------------------------------------- |
| `apiKey`       | string                   | Developer Console API key (required).                            |
| `secureMedia`  | bool                     | Encrypt media with SRTP. Default: `false`.                       |
| `logPath`      | string                   | Directory for SDK log files. Default: `"."` (working directory). |
| `jitterParams` | `optional<JitterParams>` | Global jitter-buffer settings (see below).                       |

## `AudioParams` factory methods

```cpp theme={null}
// Language Translation
AudioParams::WithLanguages(
    langIn,          // source language (BCP-47) or "*" for auto-detect
    langOut,         // target language (BCP-47)
    sampleRate,      // 8000 / 16000 / 48000
    conversationId   // optional — auto-generated if empty
);

// Speech Enhancement / Accent Translation
AudioParams::WithModel(
    modelKey,        // model identifier from Developer Console
    sampleRate       // 8000 / 16000 / 48000
);
```

## `LanguageConfig` — for `UpdateLanguageConfig()`

| Field            | Type   | Description                                       |
| ---------------- | ------ | ------------------------------------------------- |
| `languageIn`     | string | Source language BCP-47 code. `"*"` = auto-detect. |
| `languageOut`    | string | Target language BCP-47 code.                      |
| `conversationId` | string | Must match the ID used at processor creation.     |

## `JitterParams` — advanced network tuning

The adaptive jitter buffer smooths network jitter at the cost of added latency. All fields default to `−1` (use the service default). Only adjust if you have a measured need.

| Field              | Service default | Description                                    |
| ------------------ | --------------- | ---------------------------------------------- |
| `jbMaxMs`          | 500 ms          | Maximum buffer capacity.                       |
| `jbInitPrefetchMs` | 300 ms          | Initial prefetch delay before playback starts. |
| `jbMinPrefetchMs`  | 300 ms          | Adaptive floor for the jitter buffer.          |
| `jbMaxPrefetchMs`  | 400 ms          | Adaptive ceiling for the jitter buffer.        |

<Tip>Higher prefetch values improve resilience to jitter but add latency. Start with the defaults and increase only if you observe choppy audio.</Tip>
