For a stereo music stream, use AAC audio at 128 Kbps and 44.1 kHz. That is YouTube’s documented recommended stereo audio setting. Set the video bitrate separately according to your chosen resolution and frame rate; 128 Kbps is not the total stream bitrate.
Recommended audio settings
YouTube’s live-stream encoder guidance recommends 128 Kbps for stereo audio and specifies 44.1 kHz in its advanced settings. For a typical music-radio broadcast, configure the audio encoder as:
- Codec: AAC
- Channels: Stereo
- Bitrate: 128 Kbps
- Sample rate: 44.1 kHz
YouTube lists AAC or MP3 for RTMP/RTMPS live ingest. AAC is the suitable choice for the documented stereo recommendation; YouTube identifies AAC as required for 5.1 surround in that workflow. See YouTube’s live encoder settings.
Set the video bitrate separately
A radio stream with a still image, visualizer, or other video has a video track as well as audio. Choose its video bitrate from YouTube’s range for the selected resolution, frame rate, and codec. A static image may seem undemanding, but YouTube’s published table is organized by resolution and frame rate—not by whether the picture moves—so there is no universal video-bitrate figure for every music-radio stream.

#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
The stream’s total upload rate includes both tracks and related stream overhead. Do not treat the 128 Kbps audio recommendation as the required total upload speed. YouTube also recommends CBR for bitrate encoding and RTMPS for ingest; check the requirements for the encoder and ingest mode you actually use at the official settings page.
Test the stream before leaving it on
- Configure the encoder: Set AAC stereo audio to 128 Kbps at 44.1 kHz, then set the video codec, resolution, frame rate, and video bitrate using YouTube’s corresponding guidance.
- Check your upload capacity: Run a speed test, then test with the intended program rather than relying only on a speed-test result. Available upload capacity and stability depend on your connection and setup; YouTube does not prescribe a universal headroom multiplier for a 24/7 stream.
- Run a representative preflight: Include the actual audio and the kinds of video or movement your broadcast will contain. Confirm the sound is clean and that the encoder is sending the expected stream.
- Watch YouTube’s stream health: Monitor its status and messages during the test and while live. The YouTube Live API describes health feedback that can flag audio bitrate and codec issues; see its stream health documentation.
YouTube transcodes live streams into multiple output formats for viewers, but that does not remove the need to send a stable input stream. Its guidance is to test and monitor; it does not define a special audio bitrate for continuous 24/7 broadcasting or guarantee that a particular configuration will remain stable for a full day.

Keep a 24/7 broadcast running
The bitrate setting determines the stream’s encoding, not whether the equipment or connection can operate continuously. A self-hosted setup needs an encoder and dependable internet connection running for the broadcast, plus a way to notice stream-health problems. The audio recommendation remains AAC stereo at 128 Kbps; assess video settings and connection stability for your own setup rather than assuming a separate 24/7 bitrate rule.
Or let it run in the cloud
With StreamNeo, upload a recording or build a playlist, add your YouTube stream key, and go live. StreamNeo loops uploaded video from the cloud, so your computer and home connection do not have to stay on. It supports the uploaded quality up to 4K 60fps at one flat price per slot, automatically recovers if YouTube drops the stream, and the first day is free with no card. Monthly pricing is $9.99 per month. Start your free day with StreamNeo.
