# Flutter Sound Helpers API

## `convertFile()`

* Dart API: [convertFile()](https://github.com/Canardoux/tau/tree/6bd245d293bcf9a123677735835549585d32b2ee/doc/pages/tau-api/utilities/pages/flutter-sound/api/helper/FlutterSoundHelper/convertFile.html)

This verb is useful to convert a sound file to a new format.

* `infile` is the file path of the file you want to convert
* `codecin` is the actual file format
* `outfile` is the path of the file you want to create
* `codecout` is the new file format

Be careful : `outfile` and `codecout` must be compatible. The output file extension must be a correct file extension for the new format.

Note : this verb uses FFmpeg and is not available int the LITE flavor of Flutter Sound.

*Example:*

[Dart](/tau/doc/pages/tau-api/utilities/convert_file.md#dart)

[Javascript](/tau/doc/pages/tau-api/utilities/convert_file.md#javascript)

```

        String inputFile = '$myInputPath/bar.wav';
        var tempDir = await getTemporaryDirectory();
        String outpufFile = '${tempDir.path}/$foo.mp3';
        await flutterSoundHelper.convertFile(inputFile, codec.pcm16WAV, outputFile, Codec.mp3)
```

```

        Lorem ipsum ...
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://canardoux.gitbook.io/tau/doc/pages/tau-api/utilities/convert_file.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
