This SDK support record by microphone, and you can run it on Winphone(ARM).

Requirements

Follow one of the tutorials to create a project and get your host, access_key and access_secret.

• How to identify songs by sound

• How to detect custom audio content by sound

Functions

Introduction all API.

Example

run the project ACRCloudWinPhoneSDK:

	private void stopbtn_Click(object sender, RoutedEventArgs e)
        {
            if (client != null)
            {
                client.Cancel();
            }
            resultTextBlock.Text = "stoped";
        }

        private void startbtn_Click(object sender, RoutedEventArgs e)
        {
            var config = new Dictionary<string, object>();

            // Replace "XXXXXXXX" below with your project's access_key and access_secret
            config.Add("host", "XXXXXXXX");            
            config.Add("access_key", "XXXXXXXX");
            config.Add("access_secret", "XXXXXXXX");

            client = new ACRCloudClient(this, config);
            client.Start();

            resultTextBlock.Text = "recording";
        }

        void IACRCloudClientListener.OnResult(string result)
        {
            resultTextBlock.Text = result;
        }
