public class Script_Example extends SquisoScript {


    @Override
    public void onTwitchChannelPointRedeem(OnTwitchChannelPointRedeemData data, API api) throws SquisoException {

        // If the channel point reward is "Echo Brian"
        if (data.getRewardName().equals("Echo Brian")) {

            // Generate a TTS audio using the Brian voice
            // All voices can be found here: https://www.squiso.com/voices/
            SquisoData tts = api.generateTTS("ggw6pyfz", data.getRedeemText());

            // Generate a random ID that we will use through-out the script
            String randomID = StringUtil.getRandomAlphaNumericString(8);

            // Create a filename for the generated TTS
            String file = randomID + ".mp3";

            // Save the TTS audio to the disk
            api.writeFile(file, tts);

            // Log that we saved the generated TTS
            api.log("Saved generated TTS to \"" + file + "\".");

            // Create a new filename for the echo version
            String fileEcho = randomID + "_echo.mp3";

            // Add an echo effect to the audio file using FFMPEG
            // This requires that you have downloaded and added ffmpeg.exe and added it in the Squiso folder
            // FFMPEG is a free audio tool that can do a lot of audio manipulation
            String command = "ffmpeg.exe -i " + file + " -filter_complex \"aecho=0.8:0.9:500|1000:0.2|0.1\" " + fileEcho;
            api.exec(command);

            // Play the echo version
            api.playAudio(fileEcho);

        }

    }
