Button for recording and uploading an audio file


The task interface configuration guide describes the features of the HTML/JS/CSS editor. You can also try creating a button for recording and uploading audio files in Template Builder.

To add a button for audio recording and upload to the task, use the {{field type="file" sources="RECORDER" fileType="AUDIO" name="<output field name>" sources="<sources parameter>" fileType="<fileType parameter>"}} component. Example:

{{field type="file" name="result" sources="RECORDER" fileType="AUDIO" label="Record audio"}}

For a complete list of parameters, see the table.

Add a field with the file type in the output data description. Example:

"result": {
"type": "file",
"required": true

Create tasks for mobile devices if you want to use the button for recording and uploading audio files, because these devices have a built-in voice recorder. Set the Client = Mobile Toloka filter in the pool.
