For a typical stereo YouTube radio livestream, set audio to 128 Kbps at 44.1 kHz. That is the audio track only—not the total stream bitrate. If your broadcast includes a static image, you also send video, and its bitrate depends on the video codec, resolution, and frame rate.
Recommended bitrate for radio livestream audio
YouTube’s live encoder guidance recommends 128 Kbps for stereo audio at 44.1 kHz. Use this setting for ordinary stereo radio; the 384 Kbps recommendation is for 5.1 surround sound, not stereo. YouTube’s encoder settings page is undated: Choose live encoder settings, bitrates, and resolutions.
Set video bitrate separately
A radio broadcast with a still image is still an audiovisual stream when sent as live video. Set the video bitrate separately from the audio bitrate. YouTube’s recommended H.264 video bitrates include these examples:
| H.264 output | Recommended video bitrate |
|---|---|
| 360p30 | 4 Mbps |
| 480p30 | 4 Mbps |
| 720p30 | 8 Mbps |
These are video figures, not total stream rates. Choose a resolution and frame rate that suit the image and your available upload connection. The recommendation depends on codec, resolution, and frame rate; do not substitute a bitrate table for uploaded video files for YouTube’s live-ingestion settings. The current encoder recommendations are at YouTube Help.

- 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.
Encoder settings to check
- Audio: AAC or MP3 for RTMP/RTMPS, at 128 Kbps and 44.1 kHz for stereo.
- Bitrate mode: Constant bitrate (CBR).
- Keyframe interval: Two seconds recommended; do not exceed four seconds.
- Transport: YouTube supports RTMP/RTMPS and recommends RTMPS for encrypted transport.
Use the stream key and server details shown for your YouTube live stream in your encoder. Keep the key private; anyone with it may be able to send a stream to your channel.
Check upload bandwidth and stream health
Your connection must carry the complete stream: video, audio, and streaming overhead. YouTube recommends leaving 20% headroom on upload bandwidth. For example, if your configured stream uses 5 Mbps in total, plan for at least 6.25 Mbps of reliable upload capacity rather than treating 5 Mbps as the connection target. This is YouTube’s recommended headroom, not a guarantee that a connection will remain stable.

- Configure the audio and video bitrates independently, then add them to estimate the stream’s total bitrate.
- Check that your available upload speed can sustain that total with 20% headroom.
- Run a test stream before the broadcast. Watch YouTube’s stream health and listen for audio problems while checking the video.
- If you see interruptions or poor quality, lower the video resolution or bitrate first if the visual allows it, then test again.
