Start with modest output settings, test the stream before relying on it, and make sure you have the rights to broadcast every track. YouTube’s published bitrate recommendations describe what to send to its ingest service; they do not guarantee that a particular PC can encode it.
What you need before you start
- An eligible YouTube channel: it must be verified, have no live-streaming restrictions from the previous 90 days, and the creator must be at least 16. First-time live streaming may take up to 24 hours to activate. See YouTube’s live-streaming eligibility guidance and encoder setup instructions.
- An encoder such as OBS, a computer able to sustain the settings you choose, audio routed into the encoder, and a stable upload connection.
- A still station graphic or other simple visual. A camera is not necessary for an audio-first broadcast.
- Permission to broadcast the music and other material you plan to play.
There is no universal minimum CPU specification that guarantees OBS will stream successfully. OBS says the load depends on the encoder, resolution, frame rate and scene complexity, and that a compatible system is not necessarily capable of streaming. Treat the settings below as a test starting point, not a hardware guarantee; see OBS system requirements.
Set up the YouTube stream
- Enable live streaming. Complete channel verification and check that the account has no active live-stream restriction from the preceding 90 days. If this is the channel’s first live stream, allow up to 24 hours for activation.
- Create or schedule an encoder stream in YouTube Studio. Open the live-stream creation flow and choose the encoder workflow. YouTube provides a stream URL and stream key in Live Control Room.
- Copy the URL and key into OBS. In OBS, open Settings > Stream, select YouTube if offered, and connect the account or choose the stream-key option. If entering details manually, use the URL and key supplied by YouTube. Keep the key private: anyone with it may be able to send a broadcast to your channel.
- Build a lightweight scene. Add a still station image and the audio source you need. Remove browser overlays, animations and unused sources. This is practical load reduction, not a tested performance guarantee.
- Check the preview before going live. Start the encoder and confirm the picture and sound in YouTube Live Control Room. Resolve warnings there before starting the public broadcast.
Choose settings a modest PC can test
YouTube’s current encoder guidance recommends H.264, H.265/HEVC or AV1 video, up to 60 fps, constant bitrate (CBR), and a keyframe interval of two seconds (do not exceed four seconds). For stereo audio it recommends AAC or MP3, a 44.1 kHz sample rate and 128 kbps. YouTube recommends RTMPS for encrypted ingest. Its H.264 720p/30 fps guidance lists 3 Mbps as the minimum video bitrate and 8 Mbps as recommended. These are ingest settings, not measurements of PC processing capacity. Details: YouTube encoder settings.
| Setting | Practical starting point | How to interpret it |
|---|---|---|
| Video | Still image; test at a lower resolution and frame rate if the PC struggles. Try 720p/30 only if the system and upload link sustain it. | A static scene reduces unnecessary rendering work, but OBS does not publish a universal low-power preset. |
| Video bitrate | For H.264 at 720p/30, YouTube lists 3 Mbps minimum and 8 Mbps recommended. | Start lower if needed to test stability; reducing bitrate can help a constrained connection, but may reduce image quality. |
| Rate control and keyframes | CBR; two-second keyframe interval, never more than four seconds. | These are YouTube’s published encoder targets. |
| Audio | AAC or MP3; stereo, 44.1 kHz, 128 kbps recommended. | For a radio stream, prioritize clean, continuous audio and verify it in the Live Control Room preview. |
| Connection | RTMPS, preferably selected through OBS’s YouTube integration. | RTMPS encrypts the encoder-to-YouTube connection. YouTube’s developers documentation describes RTMPS over port 443; avoid manually constructing a server address when YouTube supplies one. |
OBS’s Auto-Configuration Wizard can help choose basic settings, but it cannot guarantee long-term stability. Run a representative test with the same audio, scene and network you intend to use, and monitor stream health. YouTube recommends checking upload speed with a speed test; rising dropped-frame counts in OBS can signal that the connection is unstable or cannot sustain the configured bitrate. Reduce bitrate or troubleshoot the network if the count rises. References: OBS Auto-Configuration Wizard and YouTube encoder guidance.

Route the radio audio into OBS
If the finished station mix already plays on the PC, select the relevant desktop or application audio source in OBS and verify its level in the mixer. Avoid capturing unrelated system sounds. If a presenter microphone or external line-level source is part of the show, connect compatible input hardware and select it as an audio input. YouTube identifies microphones and preamps as optional external encoder hardware; they are not required when the finished audio already plays on the computer. See YouTube’s encoder setup guidance.
Clear the music rights before broadcasting
Do not assume that music aired on terrestrial radio, included in a subscription music service, or labeled royalty-free is automatically cleared for a YouTube live broadcast. YouTube’s live-stream terms require the content provider to have the necessary rights for use on Google services, including music rights from artists, labels, publishers and other rights participants. The legal rights and licensing route can vary by territory and by the material used. Read YouTube’s Terms of Service and obtain appropriate permission for your program.

YouTube scans live streams for third-party content. It may replace the image with a placeholder and warn you; if the content continues, the stream may be interrupted or terminated. A license alone may not prevent interruption: YouTube says the channel may also need to be on the rights holder’s Content ID allowlist. Confirm any required allowlisting with the rights holder before you go live. See YouTube’s live-stream copyright guidance.
Run a continuous station as shorter sessions
YouTube automatically archives eligible streams shorter than 12 hours. A stream that exceeds 12 hours may not be captured at all, and DVR rewind may be limited or unavailable on very long streams. If replays matter, end and restart the broadcast before reaching 12 hours, verify audio continuity during a test restart, and keep a local recording as a backup. See YouTube’s archive and DVR guidance.

A PC-based encoder also depends on that computer, its audio source, power, network and account remaining available. The cited YouTube and OBS guidance does not establish a guaranteed unattended 24/7 uptime setup for an individual PC or channel.
Troubleshooting a low-power radio stream
- OBS struggles, freezes or overloads: simplify the scene, remove animations and unnecessary sources, then lower resolution, frame rate or video bitrate and test again. CPU demand varies with the encoder and scene; there is no universal minimum spec.
- Dropped frames keep rising: check upload speed and network stability, then reduce the configured bitrate if the connection cannot sustain it. A speed test checks the available upload path, but a short test does not guarantee a stable long session.
- YouTube does not receive the stream: confirm live streaming is enabled, allow for first-time activation, and check that the stream URL and private key in OBS match the current event in Live Control Room.
- Audio is missing or too quiet: verify that the correct desktop, application or input source is active in OBS, inspect its mixer level, and listen to the YouTube preview before going public.
- The stream is interrupted after music plays: stop the broadcast and review the rights for the track. If it is licensed, contact the rights holder about YouTube Content ID allowlisting; a license does not necessarily prevent a live interruption.
- No replay appears: check the stream duration. Streams longer than 12 hours may not be captured; use shorter sessions and a local recording when an archive is important.

Frequently Asked Questions
Can I stream to YouTube if my channel has never gone live before?
Yes, if the channel meets YouTube’s eligibility requirements; first-time activation may take up to 24 hours.
Do I need a microphone or audio interface?
No, not if the complete radio mix already plays on the PC. External input hardware is only needed for a microphone or line-level source.
