microphone.stop

Syntax

ue.microphone.stop(capture_id: integer, callback: function) -> boolean

The call requests capture to stop immediately. Encoding and callback delivery are asynchronous.

ue.microphone.stop(capture_id, function(result)
    if not result.ok then
        ue.log.error(result.error)
        return
    end

    -- result.wav is a binary-safe PCM RIFF/WAVE string.
    print(result.duration, result.sample_rate, result.channels, #result.wav)

    ue.http.request({
        url = "https://api.example.test/transcribe",
        method = "POST",
        headers = {
            Authorization = "Bearer " .. assert(ue.secrets.get("EXAMPLE_API_KEY"))
        },
        multipart = {
            {
                name = "file",
                filename = "voice.wav",
                content_type = "audio/wav",
                data = result.wav
            }
        }
    }, function(response)
        if not response.ok then
            ue.log.error(response.error, response.status)
            return
        end
        local decoded = assert(ue.json.decode(response.body))
        print(decoded.text)
    end)
end)

The callback result contains ok, duration, sample_rate, channels, and either wav or error. It runs on the Unreal game thread, so the decoded text can be passed directly to a reflected Blueprint function.
