# WebAssembly API reference

> Complete application API for the released WebAssembly package.

**Version:** `@ai-coustics/aic-sdk-wasm` 0.23.0, Core SDK 0.23.0. [API index](/reference/sdk/api/wasm/index) · [WebAssembly quickstart](/reference/sdk/language-bindings/wasm).

This reference covers [@ai-coustics/aic-sdk-wasm 0.23.0](https://www.npmjs.com/package/@ai-coustics/aic-sdk-wasm/v/0.23.0). Use the [WebAssembly quickstart](/reference/sdk/language-bindings/wasm) for the complete browser setup and backend token exchange. Read [initialization and lifecycle](/reference/sdk/api/wasm/initialization) before constructing SDK objects.

| Domain                                                                 | Use it to                                  |
| ---------------------------------------------------------------------- | ------------------------------------------ |
| [Initialization and lifecycle](/reference/sdk/api/wasm/initialization) | Load the module and release owned handles. |
| [Models](/reference/sdk/api/wasm/models-and-config)                    | Load model bytes and query metadata.       |
| [Enhancement](/reference/sdk/api/wasm/enhancement)                     | Enhance blocks and configure a stream.     |
| [VAD](/reference/sdk/api/wasm/vad)                                     | Run dedicated voice activity detection.    |
| [Analysis](/reference/sdk/api/wasm/analysis)                           | Collect audio and read analysis results.   |
| [Errors](/reference/sdk/api/wasm/errors)                               | Diagnose errors and recover.               |

The JavaScript API has no asynchronous processor, model downloader, file analyzer, enrollment API or OpenTelemetry configuration object. Application downloads use `fetch`; SDK processing itself is synchronous. Preserve each stream's block order and keep objects within the JavaScript context that owns their initialized module.
