OBS STUDIO: The Powerful Free Broadcasting Tool

Free Software that turns an old unused computer

into a complete Broadcast Studio

If you’re into live streaming, podcasting, or running an internet radio station on your Mac, OBS Studio (Open Broadcaster Software) is likely the best tool in your arsenal. It’s completely free, open-source, and incredibly capable—used by everyone from bedroom broadcasters to massive Twitch streamers. At High on Technology, we rely on OBS 24/7, every day to broadcast our Pirate Radio stream for Mark King Radio, our band’s outlet for raw, uncut music and talk. It’s the backbone of our broadcast operation which puts us "in your pocket right now".

How Long Has OBS Been Around?

OBS has been around for over 13 years. The original version launched in September 2012 by developer Hugh “Jim” Bailey. In 2013–2016, it evolved into the modern OBS Studio (originally called OBS Multiplatform), gaining cross-platform support and a much more powerful feature set. By 2016, the “Classic” version was retired, and Studio became the standard. As of April 2026, the current stable release is 32.1.2. It’s come a long way from its humble beginnings to become the de facto standard for live video and audio broadcasting. 

Platforms and Mac Focus

OBS Studio is truly cross-platform:

• Windows 10+
• macOS 12 Monterey and newer (native Apple Silicon and Intel builds)
• Linux (Ubuntu 20.04+ and others)

While it shines everywhere, on Mac it integrates nicely with the ecosystem—especially with Apple Silicon Macs for excellent performance. Native ARM64 support arrived in version 28 (2022), bringing big efficiency gains. For High on Technology’s setup, it runs rock-solid on recent macOS versions (Sequoia and Tahoe) and handles our audio-heavy Pirate Radio broadcasts without breaking a sweat. 

Is It Easy to Use?

Short answer: Yes—for basics. Steeper for advanced setups.

OBS has a reputation for being approachable. You can be up and streaming in minutes:

1. Add a scene.
2. Add sources (audio input, screen/window capture, video, browser, etc.).
3. Set up your stream key or recording destination.
4. Go live.

The interface is clean and logical once you grasp Scenes vs. Sources. For our Mark King Radio Pirate Radio stream, we have a simple but effective setup: multiple audio sources (mics, music players, jingles), browser sources for now-playing info, and overlays. New users might spend an afternoon watching tutorials, but the payoff is huge. 

Is It Flexible?

Extremely. This is where OBS separates itself from simpler tools.

• Unlimited scenes and sources
• Powerful audio mixing with filters (noise suppression, compression, EQ, VST plugins)
• Video filters, scaling, cropping, color correction
• Browser sources (great for dynamic text or web-based widgets)
• Plugins galore (from the official OBS forums or community repos)
• Advanced output settings (custom bitrates, encoders like Apple VT H.264/HEVC on Mac, recording formats)
• Multitrack audio, stream delay, replay buffer, and more

For our Pirate Radio use case, the flexibility is perfect. We mix live band performances, pre-recorded segments, and live calls. We can switch scenes instantly, adjust levels on the fly, and record high-quality local backups simultaneously. It scales from simple stereo audio streaming all the way to full multi-camera video productions (but don’t worry, you can start very small and for the low purchase price (free) there is nothing else like it. 

Common Gotchas on Mac

No tool is perfect. Here are the frequent pain points Mac users (including us) run into:

• Screen/Window Capture quirks — Window Capture can be laggy or glitchy; Display Capture is often smoother but uses more resources. Use “Crop to Window” where possible. 
• Permissions — macOS is strict about screen recording and microphone access. You’ll need to grant permissions in System Settings > Privacy & Security.
• Performance on newer macOS — Some users report encoder/render lag or slowdowns after updates to Sequoia/Tahoe, especially with external monitors or high resolutions. Lowering output resolution or tweaking encoders often fixes it. 
• Virtual Camera — Works well but may need extra setup or plugins for some apps.
• Plugin compatibility — After major updates, some plugins break until updated.
• Resource usage — On lower-end Macs, high-bitrate streams can tax the CPU/GPU. Apple Silicon handles it much better than Intel did.

Pro tip: Always test your full setup before going live, and keep a simple backup scene.

It’s Your Own TV Broadcast Studio

You use OBS to send your program to someone else who does the heavy lifting (like YouTube). We create our content, use OBS to send our audio and video streams to YouTube, who forwards the stream to as many people as possible watching. For a small stream like ours this is the lowest cost way to get the signal out into the world. We may call it Pirate Radio (as a tribute to early rebel broadcasters) but it’s full TV, you can check out our stream to HEAR and SEE the quality. Mary and I mix a variety of video sources (which are not locked to the audio). Our video loops after an hour but our song playlist currently runs about four hours before it loops. 

Why We Love It at High on Technology

OBS lets us run our Pirate Radio stream for Mark King Radio with professional results on a hobbyist budget. It’s stable, constantly improved by a passionate community, and completely free—no subscriptions, no watermarks, no limits. Whether you’re broadcasting a band’s internet radio show, streaming gameplay, teaching online, or just recording tutorials, OBS delivers. Look for obsproject dot com.
