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.

By the end of this lesson you'll be able to…
  • Pick the right way to get audio into OBS — controller USB, an audio interface, or a virtual loopback cable.
  • Set levels using the OBS meter so your stream is full and clip-free.
  • Choose sensible bitrate and fps for Twitch, YouTube and vertical platforms.
  • Understand the real copyright situation — and the lawful way to stream copyrighted DJ sets.

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.

RouteHow it worksBest for
Controller / mixer USBMost controllers and club mixers (DJM-style) contain a USB soundcard. Connect it to your computer and OBS sees it as an audio input device — add it as an Audio Input Capture source and your mix appears on the meters.The simplest setup — if your gear has a USB soundcard, start here.
External USB interfaceFeed your mixer's booth/record output into a small USB audio interface (e.g. a 2-in/2-out box), which OBS reads as an input. Gives you a clean, dedicated capture and a hardware level knob.Mixers without a soundcard, or when you want hardware gain control.
Virtual / loopback cableA software "cable" that carries audio between apps on the same computer. On macOS, BlackHole is the free standard; on Windows, VB-CABLE or VoiceMeeter. The paid Loopback app (macOS) does the same with a nicer interface. You route your DJ software's output into the virtual cable, and point OBS at that cable as its input.Streaming from software with no separate interface, or capturing system audio.

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.

OBS audio meter · aim your peaks here
−60 dB−20−9−6−30 dBFS

Target: let the loudest moments of your mix peak around −6 dB, touching −3 at the very most. That green-into-yellow zone is full and punchy with headroom to spare. If you're regularly hitting the red, pull the level down — a clipped stream can't be un-clipped by the viewer.

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

Pro Tip

Trust the meter, not your headphones. Your monitoring volume tells you nothing about what the stream is actually sending — you can have quiet headphones and a clipping broadcast, or blasting headphones and a stream nobody can hear. Set the send level by the OBS meter every single time, then set your own listening volume separately. They are two different knobs doing two different jobs.

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.

PlatformSensible settingVideo bitrate
Twitch1080p60, or 720p60 on a modest connection~6,000 kbps at 1080p60; 3,500–5,000 at 720p60 (Twitch caps around 6,000)
YouTube Live1080p60 (more generous than Twitch)6,000–9,000 kbps at 1080p60; 4,500–6,000 at 1080p30
TikTok / verticalVertical 9:16, 720×1280 or 1080×1920, 30fps is plentyLower — these are phone-first feeds; follow the current in-app / RTMP guidance
Pro Tip

Record locally while you stream. OBS can save a high-quality copy to your drive at the same time it broadcasts. Your local recording isn't squeezed through your upload connection, so it's cleaner than the live stream — perfect for cutting highlight clips, a YouTube upload, or a Mixcloud archive afterwards. One tick-box, and every set you play becomes content twice over.

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.

Play it straight

DJ Foundations won't teach you tricks to dodge copyright systems — pitching tracks to fool detection, chopping to evade fingerprints, or similar. Those risk your channel and the artists' livelihoods, and they're outside the spirit of the craft. Want to stream copyrighted sets? Use a licensed platform like Mixcloud Live. Want reach on Twitch/YouTube? Build a set from music you're cleared to play. That's the whole, honest answer — no asterisks.

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.

Check your understanding

Two quick questions

Pick an answer — you'll get instant feedback. Nothing is saved, no sign-up.

Q1. You're on a Mac with no audio interface and want to capture your DJ software's output into OBS. What do you reach for?
No — a mic pointed at speakers is muddy and picks up the room. You want the audio routed digitally, app to app.
That just risks clipping — it doesn't get the audio into OBS at all. Level and routing are two separate problems.
Correct. A virtual loopback cable (BlackHole on macOS, VB-CABLE or VoiceMeeter on Windows, or the Loopback app) carries audio between apps. Route your DJ software into it and point OBS at it as the input — just remember to keep monitoring so you still hear yourself.
Q2. You want to stream a set of copyrighted club tracks legally. What's the right move?
No — that's an evasion trick. It risks your channel, doesn't make the use licensed, and isn't something we'll teach. Pitching to fool detection isn't a lawful fix.
Correct. Mixcloud Live is licensed with rights-holders specifically so DJs can stream copyrighted mixes legally (via Mixcloud Pro). It's the purpose-built, honest route — no takedown roulette.
Risky and not lawful — "they might not catch it" isn't a licence. Use a licensed platform, or play music you're cleared to stream.
