For a stereo YouTube Live stream, set OBS streaming audio to 128 Kbps, use AAC, and set the audio sample rate to 44.1 kHz. These are YouTube’s published stereo encoder recommendations, not a special requirement for Indian classical music or a universal setting for every platform.
In OBS, check the streaming audio bitrate under Settings → Output, then confirm the audio sample rate and stereo channel layout in the audio settings. Test the actual stream with representative music before leaving it on overnight: a displayed setting is useful only if the broadcast is sending the expected signal and your connection can sustain the stream.
Recommended OBS audio settings for YouTube Live
For the use case in this guide, the baseline is straightforward: stereo audio, 128 Kbps, AAC, and 44.1 kHz. YouTube’s live encoder settings guidance specifies the bitrate and sample rate for stereo and lists AAC and MP3 as supported audio codecs for RTMP/RTMPS ingest. OBS describes AAC as its default, widely supported audio format in its audio and video formats guide. That makes AAC the practical compatibility choice for this YouTube setup.
The recommendation is scoped to YouTube Live. A setting that matches YouTube’s published guidance is not automatically right for a different streaming destination, a different transport, or a different audio format. If you send the same programme to another platform, check that platform’s current encoder instructions rather than assuming it accepts the same combination.
| OBS setting | Stereo YouTube Live baseline | What it controls |
|---|---|---|
| Streaming audio bitrate | 128 Kbps | How much encoded audio data OBS sends per second |
| Audio encoder | AAC | The format used to encode the audio sent to YouTube |
| Sample rate | 44.1 kHz | How often the source audio is sampled per second |
| Channel layout | Stereo | Whether the outgoing audio has left and right channels |
These settings address the audio stream, not the video stream. Video bitrate controls the encoded picture data and is configured separately in OBS. Raising video bitrate will not correct a wrong audio bitrate, and raising audio bitrate does not make a soft or blurry image clearer. If you are diagnosing dropped frames rather than sound, use a separate video-focused guide such as how to fix dropped frames when streaming pre-recorded video to YouTube Live.
The genre and the continuous schedule do not change the published stereo target. YouTube’s guidance does not give a distinct audio bitrate for a sitar recital, a bhajan programme, a raga playlist, or a 24/7 broadcast. The recommendation comes from the destination’s encoder settings, not from a genre-specific listening test. A long-running stream does, however, give you more reason to check that the audio remains present and that the connection stays healthy after launch.
Set streaming audio bitrate in OBS
Open OBS and go to Settings → Output. In the streaming output controls, find the audio bitrate setting and choose 128 Kbps for the stereo audio sent to YouTube Live. OBS options and labels can differ between versions and output modes, so if your screen does not match these words exactly, look for the streaming section’s audio bitrate control rather than changing the recording controls by mistake.
Output mode matters. OBS may present a simpler set of controls in one mode and more detailed encoder choices in another. Check that you are changing the settings used for streaming, not only the settings used when saving a local recording. A locally recorded file can sound correct while the live output uses a different bitrate or encoder configuration.
If OBS gives you separate audio tracks, take care not to confuse track selection with bitrate. The stream must send the intended track, and the bitrate setting applies to the encoded audio output rather than changing the contents of a source file. For a simple music stream with one programme mix, keep the routing simple: verify which track YouTube receives and listen to that track in the live test.
You do not need to increase audio bitrate merely because the source is a high-resolution music file or because the broadcast runs all day. The selected bitrate controls the encoded live output; it does not restore information missing from a low-quality source. At YouTube’s recommended stereo value, focus on correct codec, sample rate, channel layout, source level, and reliable delivery before experimenting with a higher number.
After changing the value, apply the settings and return to the main OBS window. Reopen the settings once if you want to confirm that the value was saved. This is a small check, but it prevents a common mismatch: preparing around a number you meant to select rather than the one that is actually active.
Choose AAC and a 44.1 kHz sample rate
Set OBS to use AAC for the streaming audio encoder and 44.1 kHz for the sample rate. YouTube lists AAC and MP3 as supported audio codecs for RTMP/RTMPS, while its stereo encoder guidance gives 44.1 kHz. OBS calls AAC its default and notes its broad support, which is why it is the uncomplicated choice for this specific YouTube Live baseline.
A codec and a sample rate are different settings. AAC describes how the audio is encoded; 44.1 kHz describes the sampling rate of the digital audio signal. The bitrate is a third setting: it describes the amount of encoded audio data sent over time. They work together, but changing one does not silently change the other. For example, selecting AAC does not guarantee that OBS is set to 128 Kbps, and entering 128 Kbps does not ensure the sample rate is 44.1 kHz.
In OBS, find the audio settings and set the sample rate to 44.1 kHz. Menu placement and wording can vary with the OBS version, so check the current application rather than relying on a remembered screenshot. If you use audio interfaces or virtual devices, inspect their configured sample rates too. When devices run at different rates, software may resample audio; keeping the project and programme path aligned reduces avoidable complexity.
This is not a recommendation to force 44.1 kHz for every destination, source, or audio workflow. Another platform may publish a different ingest target, and some production setups may need to preserve a different source rate for reasons outside this stream. Use YouTube’s current guidance for this YouTube broadcast, and use the destination’s own instructions when you stream elsewhere.
A higher sample rate or audio bitrate is not a shortcut to better-sounding music. A poor recording, clipping during mixing, a noisy input, or an unstable upload connection cannot be fixed by changing an encoder number. For Indian classical music, listen especially to sustained notes, quiet passages, and the natural decay after a plucked or struck note; these make it easier to notice crackle, clipping, drop-outs, or abrupt level changes.
Confirm the output is stereo
The 128 Kbps recommendation above is for stereo. Before going live, confirm that OBS is outputting two channels rather than mono. A stereo source may have separate left and right information, but a source can also be dual-mono, or a mixer can route the same signal to both sides. The important check is that the stream’s channel layout matches the intended programme and YouTube setting.
Use headphones to listen to the OBS programme mix and, where possible, the actual YouTube stream. Check left and right balance with content that contains genuine stereo information, or use a known test recording. Do not assume that hearing sound in both earpieces proves the stream is meaningfully stereo: identical audio in both channels can sound centred while still being a mono mix duplicated to left and right.
For a single microphone or a mono music source, stereo encoding does not invent width. It can send the same mono signal through both channels. That may be acceptable for your programme, but understand what the source is doing before changing the entire mix. Avoid adding artificial stereo effects just to make the meters look different; a stable, clear mono source can be preferable to a wide mix that is unbalanced or distracting.
Check the audio mixer and routing as well. A source may show activity on its meter yet be muted on the stream track, routed to a different output, or duplicated at an unintended level. Confirm that the intended music source is active, that desktop or monitoring audio is not being captured a second time, and that no unused microphone is adding room noise. Listen to the programme rather than treating the meters as proof of quality.
Test the stream and check audio quality
Run a private or otherwise controlled test before making the stream part of a 24/7 schedule. YouTube recommends testing with representative content and monitoring stream health and messages during a broadcast. Use the actual music material and OBS scene you intend to leave running, including quiet sections and changes in instrumentation. A short test with a loud opening passage will not tell you whether a soft alap, tanpura bed, or spoken introduction is too quiet or disappears.
Listen at the YouTube end as well as in OBS. The local monitoring signal may not include the same encode, upload, ingest, and playback path as the viewer’s stream. Check for clipped peaks, audible distortion, gaps, sudden level changes, unwanted room noise, and missing channels. YouTube also processes live streams for playback, so a viewer’s output is not simply the unmodified file played back from OBS.
Pay attention to stream health and any messages shown in YouTube Studio. A warning can point you towards a mismatch or delivery problem, but interpret it in context and consult the current official guidance rather than treating every message as proof that one particular audio value is wrong. Google’s YouTube Live Streaming API documentation includes stream health and configuration concepts; it is useful background, not a guarantee that every diagnostic applies to every account or ingest setup.
A 24/7 stream should be checked after it has been running for a while, not just at the instant you press “Go Live”. Listen again after a scene change, playlist transition, or source restart. If a local machine will run OBS continuously, keep in mind that the stream depends on that machine, its audio devices, power, and internet connection remaining available. For a more general look at the trade-offs around continuous playback on a local device, see how to loop a YouTube Live playlist on an Android TV box in India.
Choose a video quality and total stream configuration that your upload connection can reliably sustain. Audio is a small part of the total data sent compared with video, but a saturated or unstable uplink can affect the whole broadcast. If the stream drops or the OBS connection indicator deteriorates, check the connection and overall output settings rather than raising the audio bitrate in response. The guide to drops during scheduled VPS backups covers another cause of delivery trouble that is separate from audio encoding.
Adjust only when there is a specific reason
Start with the published YouTube stereo baseline and change a setting only when you can identify a reason. If the stream is mono by design, another platform specifies a different ingest target, or an audio workflow requires a different rate, make a deliberate adjustment and retest. Do not change several settings at once: if the result improves or worsens, you will not know which change mattered.
If listeners report harsh or distorted sound, first check input gain and OBS mixer levels. Peaks may be clipping before they reach the encoder, and lowering the encoder bitrate will not undo clipping that already happened. If sound is too quiet, inspect source and programme levels before changing encoding settings. Make adjustments while watching the meters and listening to the output, then review the streamed result.
If the sound stutters or disappears, distinguish an audio encoding problem from a wider delivery interruption. Check whether OBS remains connected, whether the source continues to play, whether an audio device has disconnected, and whether YouTube reports a stream-health issue. A continuously running stream is sensitive to ordinary changes such as a computer restart, an output device switching, or a playlist reaching an unexpected end. The bitrate alone cannot protect against those events.
If your upload capacity is limited, do not assume that reducing audio below the YouTube recommendation is the first or best fix. Look at the full stream, especially the video configuration and competing network use, and select a quality the connection can sustain. YouTube’s guidance is a target for the encoder input, while your local conditions determine whether that output can be delivered consistently.
You may also decide that a local OBS computer is not the right operating arrangement for a channel that must continue when your own computer is off. In that situation, a cloud-based workflow can remove the need to keep OBS and the local machine running; StreamNeo is designed to take an uploaded video and stream it continuously to YouTube, with the broadcast monitored and restarted if it drops. That does not replace checking your channel, source rights, stream settings, or the actual live output.
The same discipline applies to other platforms: do not copy this baseline blindly. Consult the destination’s current encoder requirements, confirm its accepted codec and channel format, and test with the intended programme. Keep a note of the working OBS profile so a later change does not leave the channel with an accidental mismatch.

FAQ
Is 128 Kbps enough for Indian classical music on YouTube Live?
For stereo YouTube Live, 128 Kbps is the audio bitrate in YouTube’s published encoder guidance. It is a platform recommendation, not a genre-specific finding or a promise that every source will sound good. Check the recording, levels, stereo routing, and actual streamed audio as well.
Should I set OBS to 44.1 kHz or 48 kHz?
For this stereo YouTube Live setup, YouTube’s guidance gives 44.1 kHz. That does not make 44.1 kHz the right value for every destination or production workflow. If your source devices or another platform require a different rate, consult the relevant current documentation and test the full signal path.
Does audio bitrate change video quality?
No. OBS audio bitrate controls encoded audio data, while video bitrate controls encoded picture data. They are separate settings, so changing one does not directly improve the other. If the image is dropping frames or looking poor, investigate video and connection settings independently.
Can I leave the stream running overnight after one test?
A test is a useful start, but it cannot prove that a continuous broadcast will remain healthy indefinitely. Check the live output and YouTube stream health after launch, and review it again after transitions or source changes. A 24/7 schedule makes it important to plan for interruptions in the computer, audio source, power, and connection.
