If you are a TypeScript developer working on a Windows application that requires audio manipulation, you may come across the need to change the audio mixer settings programmatically. In this blog post, we will explore different solutions to achieve this goal using TypeScript.

Solution 1: Using the Windows Core Audio API

The Windows Core Audio API provides a way to interact with the audio mixer settings in Windows. To change the audio mixer, we can make use of the IAudioEndpointVolume interface. Here’s an example code snippet:


import * as windows from 'windows';

const audioDeviceId = 'your-audio-device-id';
const audioMixerLevel = 0.5;

const audioDevice = new windows.AudioDevice(audioDeviceId);
audioDevice.setVolume(audioMixerLevel);

Solution 2: Using the NAudio library

NAudio is a popular audio library for .NET that provides a high-level API for audio manipulation. To change the audio mixer using NAudio, we can make use of the MMDeviceEnumerator and MMDevice classes. Here’s an example code snippet:


import { MMDeviceEnumerator, EDataFlow, ERole } from 'naudio';

const audioDeviceId = 'your-audio-device-id';
const audioMixerLevel = 0.5;

const enumerator = new MMDeviceEnumerator();
const audioDevice = enumerator.GetDevice(audioDeviceId);
audioDevice.AudioEndpointVolume.MasterVolumeLevelScalar = audioMixerLevel;

Solution 3: Using the WASAPI library

WASAPI (Windows Audio Session API) is a low-level audio API provided by Microsoft. To change the audio mixer using WASAPI, we can make use of the IAudioEndpointVolume interface. Here’s an example code snippet:


import * as wasapi from 'wasapi';

const audioDeviceId = 'your-audio-device-id';
const audioMixerLevel = 0.5;

const audioDevice = new wasapi.AudioDevice(audioDeviceId);
audioDevice.setVolume(audioMixerLevel);

These are three different solutions you can use to change the audio mixer programmatically in a Windows application using TypeScript. Choose the one that best fits your requirements and start manipulating the audio settings with ease!
