Perfect stream audio

You're ready to stream your first set. You fire up OBS, hit go live, and the chat fills with the same two comments every new DJ streamer sees: "no sound" and "it's distorted." Getting your mix out of the mixer and into OBS cleanly — loud enough to feel, never clipping — is a small technical hurdle that stops a lot of talented DJs at the door. This lesson clears it: three ways to get the audio in, how to set levels that never crackle, the right video settings per platform, and the honest, lawful truth about music copyright.

01Three ways to get your mix into OBS

OBS doesn't care how the audio arrives — it just needs your DJ mix to show up as an input device it can add to the Audio Mixer. There are three routes, from simplest to most flexible. Pick the one that matches your gear.

One thing to watch with the virtual-cable route: if you send all your audio into the cable, you can accidentally mute your own speakers, because the sound goes to OBS instead of your monitors. The fix is monitoring — either set OBS's audio monitoring to "Monitor and Output," or use an aggregate/multi-output device so the mix reaches both the virtual cable and your speakers. If your monitors are plugged into your controller directly, you won't hit this at all.

02Setting levels so nothing clips

This is where most streams go wrong. Digital audio has a hard ceiling — 0 dBFS. Push past it and the signal doesn't just get louder, it clips: the peaks get chopped flat and you hear harsh crackle. Unlike a mixer's warm analogue overdrive, digital clipping is ugly and permanent. So the whole game is: get a full, healthy signal that leaves a little room at the top.

Set the level as early in the chain as you can, then trim in OBS only if needed:

• At the source: set your controller/interface trim or your DJ software's master so a loud track peaks in that healthy zone. Many DJ apps have a Headroom or output limiter setting — leaving a little headroom (e.g. −6 dB) protects you from surprise peaks.
• In OBS: use the fader in the Audio Mixer, and open Advanced Audio Properties for finer control. Watch the meter as your loudest track plays — that's your reference, not a quiet intro.
• Optional safety net: add a Limiter filter on your audio source in OBS set near −1 to −2 dB. It catches the odd rogue peak without you riding the level all night. It's a seatbelt, not a substitute for good gain staging.

03Video settings for each platform

A DJ stream is mostly you, your gear and some lights — not a fast-moving video game — so you don't need heroic bitrates. What you do need is a bitrate your upload can comfortably sustain, because a stream that stutters loses viewers faster than one that's merely soft. As a rule of thumb, keep your streaming bitrate to roughly half of your tested upload speed so there's headroom.

• Frame rate: 30fps is genuinely fine for a DJ cam; 60fps looks a touch smoother but costs more bitrate. If your connection is tight, drop to 30fps before you drop resolution.
• Encoder: if you have a recent GPU, hardware encoding (NVENC on Nvidia, or Apple VideoToolbox on Mac) frees up your CPU for OBS and your DJ software. Software (x264) can look slightly better at the same bitrate but works your CPU harder.
• Audio bitrate: for music, push OBS's audio bitrate up to 256 or 320 kbps where the platform allows — it's the part your audience is really there for.
• Test first: run a private/unlisted stream and watch it back on another device before you go live for real.

04The copyright reality — told straight

Here's the honest version, because half-truths get DJs' channels muted or banned. Most of the music you mix is owned by someone — labels, publishers, the artists. Streaming it publicly is a use that normally needs a licence. General platforms like Twitch and YouTube are not licensed for you to play copyrighted DJ sets, and they use automated systems that can mute your audio, cut your stream, or issue copyright strikes. That's not the platform being unfair — it's them not holding the rights for your track selection.

The lawful, purpose-built answer is Mixcloud Live. Mixcloud has struck licensing deals with rights-holders — the major labels plus hundreds of independents through collective agreements — specifically so DJs can stream copyrighted mixes legally. A Mixcloud Pro subscription unlocks live streaming under those licences, which is why it doesn't hit you with the takedowns you'd get elsewhere. It's the straightforward, legitimate route, and it exists precisely because of the problem above.

Other honest, lawful options: play music you have the rights or permission to use (your own productions, royalty-free/creative-commons catalogues, or promos cleared for streaming), or read and follow each platform's current music policy rather than hoping the filters miss you.

Get these four things right — a clean input, levels that never clip, sensible video settings, and a lawful home for your music — and your stream will look and sound like you've been doing it for years. The tech fades into the background, and what's left is the only thing that matters: you, playing great music, to people anywhere in the world.
