-c:a aac -b:a 128k -ar 44100 -ac 2
-c:a aacselects AAC audio encoding.-b:a 128ksets the audio bitrate target to 128,000 bits per second. FFmpeg documentsbas a bitrate in bits per second; specifying it activates constant-bitrate mode for FFmpeg’s native AAC encoder.-ar 44100sets the audio sample rate to 44.1 kHz.-ac 2requests two audio channels: stereo.
YouTube’s live encoder guidance recommends AAC or MP3 for RTMP/RTMPS audio and recommends CBR. For stereo, it specifies 44.1 kHz and 128 kbps. These settings are an output target, not proof that YouTube has accepted the stream or that every audio segment will consume exactly 128 kbps.

The audio options belong among the output options before the output URL. The example includes a video encoder because a YouTube radio livestream still needs a video component; choose video settings and an ingest configuration appropriate to your actual source and YouTube setup. Do not publish or expose your stream key.
Choose stereo or 5.1 based on the program
YouTube’s published live encoder guidance distinguishes ordinary stereo from 5.1 surround sound. Use the layout that matches the program being produced and delivered, not simply the larger bitrate.

| Audio layout | YouTube-listed sample rate | YouTube-listed audio bitrate | When it fits |
|---|---|---|---|
| Stereo (2 channels) | 44.1 kHz | 128 kbps | Typical stereo radio program |
| 5.1 surround | 48 kHz | 384 kbps | Program actually produced and delivered in 5.1 |
The 384 kbps figure is for 5.1, not a higher-quality default for stereo radio. YouTube Help’s page, “Choose live encoder settings, bitrates, and resolutions,” does not state a publication year.
Recommended Free Tools
Verify the encoded audio and test the ingest
- Check FFmpeg’s output information and confirm that the audio stream is AAC with a 44.1 kHz sample rate and two channels.
- Run a YouTube test stream with representative audio before using the configuration for a continuous broadcast. YouTube recommends testing before going live and monitoring stream health during the stream.
- Check YouTube Live Control Room or the Live API health messages. If a diagnostic reports a bitrate, codec, sample-rate, or channel-count problem, use that specific message to identify which output setting to review.
Fix common audio-setting mismatches
- YouTube reports the wrong audio bitrate: confirm
-b:a 128kis applied to the output audio stream and appears before the output URL. Do not mistake the video bitrate option-b:vfor an audio setting. - The audio codec is unsupported or unexpected: confirm the output uses
-c:a aac. YouTube’s RTMP/RTMPS guidance lists AAC and MP3 as supported audio codecs. - YouTube reports a sample-rate or channel-count mismatch: verify
-ar 44100 -ac 2for stereo, and check the encoded stream information rather than relying only on the command text. - A stereo stream was configured at 384 kbps: that is YouTube’s listed 5.1 audio bitrate. For ordinary stereo, use the 128 kbps recommendation.
- The stream still has an ingest or video problem: these audio options do not by themselves validate the video component, stream key, or overall ingest configuration. Review YouTube’s stream-health messages and the corresponding part of the setup.
Keep a pre-recorded radio stream running without a local encoder
If the goal is to keep uploaded recordings playing continuously on YouTube rather than to encode a live microphone or other real-time source, StreamNeo is a cloud option. Upload a recording or build a playlist, add your YouTube stream key once, and go live; the cloud loops the uploaded video, so your computer and home connection do not have to stay on. It plays uploaded videos, not a live camera feed, and streams to YouTube only.

- PLUG IN AND HEAR SOUND IN SECONDS - USB Type-A connector with a 3.5mm stereo headphone output and a separate 3.5mm mono microphone input. No drivers, no software, no external power - the adapter is USB bus-powered and is recognized as a standard USB audio device.
- WORKS ON WINDOWS, MAC AND LINUX - Driverless on Windows 98SE/ME/2000/XP/Server 2003/Vista/7/8, Linux and Mac OSX, and compliant with the USB Audio Device Class 1.0 specification, so any system that supports class-compliant USB audio will see it. Select it as the sound output and input device after plugging it in.
- TWO JACKS, TWO JOBS - The green jack is stereo OUT for headphones or powered speakers; the pink jack is mono microphone IN for a 3.5mm mic. It does NOT support 4-pole headsets on a single combo plug, it does NOT power passive speakers, and it does NOT add surround sound - it is a stereo 2-channel adapter.
- FOR LAPTOPS AND DESKTOPS THAT NEED AN AUDIO PORT BACK - Adds a headphone and mic port to a laptop, desktop, or mini PC whose onboard jack has failed or was never there. Managed and work-issued computers can block new USB audio devices by policy - check with your IT department before ordering for a company machine.
