How to Split Audio to Multiple Speakers: Step-by-Step Guide

How to Split Audio to Multiple Speakers

To split audio to multiple speakers simultaneously, you can use built-in OS settings like Stereo Mix on Windows or Multi-Output Device on macOS. For more control, third-party software like Voicemeeter or hardware solutions like 3.5mm Y-splitters and Bluetooth transmitters allow you to route a single audio stream to two or more output devices with minimal latency.

TL;DR: Quick Ways to Split Audio

• Windows Users: Use Voicemeeter Banana (Free) or enable “Listen to this device” in Sound Settings.
• Mac Users: Use the native Audio MIDI Setup utility to create a Multi-Output Device.
• Hardware Seekers: Buy a 3.5mm Audio Splitter or a Dual Bluetooth Transmitter.
• Mobile Users: Use Samsung Dual Audio (Android) or Share Audio (iOS/AirPods).

Understanding the Basics of Audio Routing

Before diving into the steps, it is important to understand that operating systems usually default to a single Primary Output. When you plug in headphones, the system often mutes the speakers. To how to split audio to multiple speakers, we must trick the OS into sending the signal to a “Virtual Bridge” or an aggregate device that then duplicates the signal.

In my experience setting up multi-room audio for events, the biggest challenge isn’t the connection—it’s latency. If one speaker is wired and the other is Bluetooth, you will notice a “delay” or echo. We will address how to fix this using buffer settings later in this guide.

Method 1: Windows Native Settings (The “Stereo Mix” Trick)

Windows has a “hidden” feature called Stereo Mix that allows you to record what is playing on your output and loop it back to another device. This is the fastest way to how to split audio to multiple speakers without downloading new software.

Step-by-Step Configuration:

1. Right-click the Speaker Icon in your system tray and select Sounds.
2. Navigate to the Recording tab.
3. Right-click an empty space and ensure “Show Disabled Devices” is checked.
4. Find Stereo Mix, right-click it, and select Enable.
5. Right-click Stereo Mix again and go to Properties.
6. Click the Listen tab.
7. Check the box for “Listen to this device”.
8. In the dropdown menu under “Playback through this device”, select your second set of speakers.
9. Click Apply.

Expert Insight: This method works best if both sets of speakers are connected directly to the motherboard. If you experience a slight delay, you may need to adjust the exclusive mode settings in the Advanced tab of your playback devices.

Method 2: Using Voicemeeter Banana (Best for Professionals)

If you want the most reliable way to how to split audio to multiple speakers with zero-latency control, Voicemeeter Banana is the industry standard. I use this software daily for my streaming setup to split game audio between my headphones and my recording software.

Setup Guide for Voicemeeter:

1. Download and install Voicemeeter Banana from the VB-Audio website.
2. Restart your computer (this is critical for the virtual drivers to initialize).
3. Open the app. On the top right, you will see sections labeled A1, A2, and A3.
4. Click A1 and select your main speakers (Choose WDM for the best balance of speed and stability).
5. Click A2 and select your second set of speakers or headphones.
6. In the middle section (Virtual Inputs), make sure the A1 and A2 buttons are highlighted on the Voicemeeter VAIO strip.
7. Finally, go to your Windows Sound Settings and set your Default Output Device to Voicemeeter Input.

Why this works: Voicemeeter acts as a virtual mixing board. It captures all system sound and “splits” it perfectly to as many as three hardware outputs simultaneously.

Method 3: macOS Audio MIDI Setup (Native & Powerful)

Apple makes it remarkably easy to how to split audio to multiple speakers without any third-party downloads. The tool is already on your Mac, hidden in the Applications folder.

How to create a Multi-Output Device:

1. Press Cmd + Space and type “Audio MIDI Setup”.
2. Click the “+” icon in the bottom left corner.
3. Select Create Multi-Output Device.
4. On the right-hand panel, check the boxes for all the speakers/headphones you want to use.
5. Pro Tip: Check the Drift Correction box for your secondary devices to ensure the audio stays in sync over long periods.
6. Right-click the new “Multi-Output Device” and select “Use This Device For Sound Output.”

Method 4: Hardware Solutions (The “No-Software” Approach)

Sometimes software is too glitchy, especially for live performances. If you need to how to split audio to multiple speakers for a party or a home theater, hardware is the most stable choice.

3.5mm Analog Y-Splitters**

This is a simple cable that plugs into your laptop or phone jack and provides two female ports.

• Pros: Cheap, no power required, zero lag.


• Cons: It halves the power (voltage) sent to each speaker, which can lead to lower volume.

Powered Audio Distributors**

Unlike a simple cable, a Powered Splitter (or Headphone Amp) takes the signal and amplifies it for each output. I recommend the Mackie HM-4 or the Behringer HA400 if you need to split audio to four different speakers without losing volume.

Bluetooth Transmitters (Dual Link)**

If you are using wireless speakers, you need a Bluetooth 5.0 Transmitter with “Dual Link” capability. Brands like 1Mii or Avantree produce adapters that plug into your TV’s optical port and stream to two pairs of Bluetooth headphones at once.

Method 5: Mobile Solutions (iOS & Android)

Splitting audio on mobile devices has become a standard feature for flagship phones.

Samsung Dual Audio (Android)

If you have a Samsung Galaxy (S8 or newer), you can output to two Bluetooth speakers at once.

1. Connect both speakers via Bluetooth.


2. Swipe down the Quick Settings panel.


3. Tap Media.


4. Select both Bluetooth devices.

Apple Audio Sharing (iOS)

For iPhone users, this is limited to AirPods and Beats headphones.

1. Connect your AirPods to your iPhone.


2. Tap the AirPlay icon in the Control Center.


3. Tap Share Audio and hold the second pair of AirPods near the phone.

Troubleshooting Common Audio Splitting Issues

How to Fix Audio Latency (Lag)

When you split audio to multiple speakers, one speaker often sounds “behind” the other. This usually happens when mixing a wired speaker with a Bluetooth one.

• Solution: In Voicemeeter, you can adjust the buffering (msec) in the settings menu to delay the faster speaker so it matches the slower one.


• Solution: Use ASIO drivers if your hardware supports them, as they bypass the Windows audio engine entirely for faster processing.

Static or Hissing Noises

If you use a cheap passive splitter, you might hear a “hum.” This is often a ground loop.

• Fix: Purchase a Ground Loop Noise Isolator. It’s a small $10 plug that eliminates the electrical interference between your speakers.

Frequently Asked Questions

Can I split audio between USB speakers and a 3.5mm jack?

Yes. Since these are two different hardware IDs, you cannot do this with a physical cable. You must use Voicemeeter (Windows) or Audio MIDI Setup (Mac) to create a virtual bridge between the two different connection types.

Does splitting audio reduce the sound quality?

Using a passive (non-powered) cable splitter can reduce the volume and slightly degrade the frequency response because the electrical signal is divided. However, using software splitting or powered hardware maintains 100% of the original digital audio quality.

How many speakers can I connect at once?

Using Voicemeeter Potato (the premium version), you can split audio to up to five physical hardware devices. On Mac, the Multi-Output Device setting theoretically supports as many devices as your CPU can handle, though 3-4 is the practical limit before you experience stuttering.

Is there an app to split audio on Windows 11?

While Windows 11 has a modern volume mixer, it doesn’t natively “clone” audio to two devices simultaneously. The best app for this remains EarTrumpet for UI management or Audio Router (available on GitHub), though Voicemeeter is the most stable.
