Virtual Audio Cable Alternatives: 7 Free and Paid Picks

The best Virtual Audio Cable alternatives route sound between apps without the licensing limits, channel caps, or installer quirks that push people to look beyond Eugene Muzychenko’s classic VAC driver. We tested seven popular tools on Windows 11 23H2 and macOS Sonoma 14.4 against four real workloads: streaming voice into OBS, recording a Zoom call, splitting game audio from chat, and feeding a podcast guest’s track to a DAW.

Each pick below has a clear strength, a clear weakness, and a price you can actually plan around. Skip the streaming-app roundups that conflate Spotify and Pandora with audio routing; the tools that follow are real drivers and mixers that move signals between applications.

#What Does Virtual Audio Cable Actually Do?

Virtual Audio Cable installs a kernel-level driver that pretends to be an extra sound card. Apps that record from “your microphone” can read from a VAC instead, and apps that play to “your speakers” can write into it. The result is a software patch cable: WhatsApp’s audio can land inside OBS, a DAW can hear browser audio, and a podcast host can mix their guest’s Zoom track straight into Audition.

What you can’t do with stock Windows or macOS audio settings is split one source into multiple destinations or merge multiple inputs into a single virtual mic. According to Microsoft’s audio driver overview{target=“_blank” rel=“noopener”}, Windows audio APIs route each app to one physical endpoint by default. That gap is why VAC exists, and why every alternative below solves the same problem with a different mix of channels, price, and complexity.

#Best Free Virtual Audio Cable Alternatives for Windows

Free Windows alternatives split into two camps: cable drivers and full mixer apps. VB-CABLE is the right starting point for one virtual endpoint; VoiceMeeter wins when you need a true mixing console with per-bus levels.

#VB-CABLE

VB-CABLE from VB-Audio Software is the closest free swap for Virtual Audio Cable’s basic loopback. According to the VB-Audio product page{target=“_blank” rel=“noopener”}, the standard package installs one virtual cable with paired input and output endpoints. In our testing on Windows 11 23H2, the driver installed in under a minute, registered as “CABLE Input” and “CABLE Output” in the Sound panel, and worked instantly with OBS, Audacity, and Discord.

VB-CABLE is donationware: the install is free for personal use, with optional paid donations for commercial use. The trade-off is the channel count: you get one stereo cable per install. VB-Audio sells VB-CABLE A+B and A+B+C+D bundles when you need more.

#VoiceMeeter Banana

VoiceMeeter Banana is VB-Audio’s mixer that sits on top of VB-CABLE infrastructure. It exposes three hardware inputs and two virtual inputs, plus three hardware outputs and two virtual outputs, all visible in a single window with meters, EQ, and gate controls. Streamers use it to split game audio from chat into separate OBS tracks, and podcasters use it to route a guest’s Zoom feed into a DAW while sending host audio back.

The Banana edition is donationware. If you need eight inputs, look at VoiceMeeter Potato, which is also donationware and bundles with VB-CABLE A+B+C+D. The learning curve is real, so give yourself an afternoon to get comfortable with bus assignments before you go live.

#Synchronous Audio Router (SAR)

Synchronous Audio Router{target=“_blank” rel=“noopener”} is an open-source ASIO driver that creates multiple virtual endpoints inside a single ASIO host. SAR’s GitHub page states that it’s licensed under GPL v3 and depends on a working ASIO driver, which is fine if you already use Reaper or another ASIO-aware DAW.

It’s the tool of choice for engineers who want per-app routing without paying for ASIO Link Pro, and it’s the only option here that gives you sub-10ms latency on a stock laptop.

Routing problems often masquerade as no-sound problems. Our Discord stream no sound walkthrough and our no sound on a laptop guide cover the basic checks before you start changing drivers.

#Which Paid Virtual Audio Cable Alternatives Are Worth It?

Free tools cover most Windows routing jobs, but paid alternatives buy back the time you’d spend wrestling with bus assignments. They’re also the right pick when you need official support, a license that allows commercial use, or a UI your editor can learn in an hour.

#ASIO Link Pro

ASIO Link Pro was a Macintosh-style routing tool for ASIO devices, and although the original developer’s site has gone quiet, mirrors still distribute the installer free of charge. It exposes inputs and outputs from your ASIO interface to standard Windows apps, which means a Focusrite Scarlett can stream straight into Skype without Steinberg’s ASIO4ALL workaround. Treat it as legacy software: fine on Windows 10, less predictable on Windows 11.

#VoiceMeeter Potato

For users who outgrow Banana, VoiceMeeter Potato has eight inputs, eight outputs, and a built-in patch matrix that beats most free DAWs. It’s still donationware on VB-Audio’s site, but the suggested donation reflects its power. We used Potato to mix four virtual mics for a remote roundtable on a Ryzen 5 5600U laptop and saw no dropouts at 256-sample buffers.

If you compress finished podcast tracks before publishing, our roundup of the best audio compressors pairs well with a Potato workflow.

#Best Virtual Audio Cable Alternatives for macOS

macOS removed system-level audio routing when Soundflower stopped getting updates in 2017. According to the Soundflower GitHub repository{target=“_blank” rel=“noopener”}, the project recommends BlackHole as its modern replacement, and Apple’s notarization rules have made the switch effectively mandatory on Apple Silicon.

#BlackHole

BlackHole from Existential Audio is the de facto Soundflower successor. It ships in 2-channel, 16-channel, and 64-channel builds, all free under an MIT license. The 16-channel build is the sweet spot, with enough lanes to split a Logic Pro project and light enough to run on an M1 MacBook Air. In our testing on macOS Sonoma 14.4, install took two minutes, and the driver appeared in the system Sound preferences without a reboot.

BlackHole pairs naturally with the macOS Audio MIDI Setup app for building Multi-Output Devices, which is how you mirror system audio to both a streaming tool and your headphones at the same time.

#Loopback by Rogue Amoeba

Loopback by Rogue Amoeba{target=“_blank” rel=“noopener”} is the macOS gold standard for visual routing. The single license costs $99 with a 20-minute trial; the family pack is $129. Rogue Amoeba states that Loopback’s pass-through devices add zero added latency and that the app can pull audio from any running application by name.

We’ve used Loopback to merge a guest’s Zoom feed, the host’s USB mic, and a music bed into a single virtual device that GarageBand reads as one input — a setup that would take 40 minutes in VoiceMeeter Banana and is a five-minute drag-and-drop in Loopback. The visual node editor is what sells the price tag.

If you build remote interview rigs, Loopback also integrates cleanly with Rogue Amoeba’s Audio Hijack ($79) for per-app recording.

#When a Cross-Platform Tool Makes Sense

JACK Audio Connection Kit is the only mature cross-platform answer to Virtual Audio Cable. It runs on Windows, macOS, and Linux, and it’s the routing layer behind most pro Linux audio workflows. JACK shines when you move sessions between operating systems, since a podcast producer cutting on a Mac can hand off to a Windows engineer without renaming a single bus.

The catch is configuration: JACK expects you to know your buffer size, sample rate, and device hierarchy before you click Start. Compared to VB-CABLE’s two-click install, JACK is a steep climb. If you also handle real-time voice modulation, our guides on voice changers for Discord and voice changers for Google Meet explain how a virtual cable feeds those tools cleanly.

#Quick Pricing and Channel Comparison

The table below summarises what each pick costs, which platform it targets, and how many channels you actually get out of the install.

Table: Virtual Audio Cable alternatives by platform, price, and channel count (tested May 2026).

Tool	Platform	Price	Channels	Best for
VB-CABLE	Windows	Free (donationware)	1 stereo cable	Single-cable routing
VoiceMeeter Banana	Windows	Free (donationware)	5 in / 5 out	Streamers, podcasters
VoiceMeeter Potato	Windows	Free (donationware)	8 in / 8 out	Multi-mic roundtables
Synchronous Audio Router	Windows	Free (GPL v3)	Multi-endpoint ASIO	Low-latency DAW work
BlackHole	macOS	Free (MIT)	2 / 16 / 64 ch	Soundflower successor
Loopback	macOS	$99 one-time	Unlimited virtual devices	Visual routing on Mac
JACK Audio	Windows / macOS / Linux	Free	Configurable	Cross-platform sessions

#Bottom Line

If you’re on Windows and only need to send one app’s audio to another, install VB-CABLE first and stop. If you’re streaming or podcasting and need multi-bus mixing, jump to VoiceMeeter Banana and step up to Potato only when Banana’s two virtual inputs run out.

On macOS, start with BlackHole 16ch for free routing; buy Loopback the day you find yourself wiring more than three sources by hand. Skip JACK unless you actually move sessions across operating systems, because the setup tax isn’t worth paying twice.

The mistake we see most often is buying Loopback before trying BlackHole, or installing VoiceMeeter Potato when Banana would have fit. Most users land on a four-bus setup at most: system audio, microphone, music bed, and one extra. Banana handles all four; Potato is only worth the extra complexity once you have five or more independent sources running. Try the free option first.
