A 24/7 sleep sounds stream can use one video file for the picture and a separate audio file for rain, brown noise, waves, or another sleep sound. In OBS Studio, you add them as independent sources, loop each one, and send the finished scene to YouTube Live.
This approach gives you more control than baking everything into one video, but it also gives you two playback paths to check. The picture and sound may not restart together, and a local computer is still responsible for keeping the broadcast running.
Choose and prepare the audio and visual files
Start by deciding what the viewer should see and hear during one complete cycle. For example, you might use a slow animated night window as the visual source and a long rain recording as the audio source. The two files do not need to be the same length, but you should understand what happens when each one reaches its end.
OBS Media Source supports local video files such as MP4, TS, MOV, FLV, MKV, AVI, GIF, and WebM. It also supports audio files including MP3, AAC, OGG, and WAV, according to the OBS Media Sources documentation. Use a format that your computer can decode reliably rather than choosing a file only because it is convenient to download.
Keep the working files in a stable folder. Do not leave them in a temporary downloads folder or on a removable drive that may be disconnected while OBS is running. If you move or rename a source after building the scene, OBS may no longer find it.
Use filenames that tell you what each file is for. A folder might contain:
sleep-stream/
visuals/night-window-loop.mp4
audio/steady-rain.wav
records/stream-backup/
The visual file should be large enough to fill the canvas without awkward stretching. If it is a small still image, OBS can display it, but a video loop may be less likely to reveal a completely frozen picture to someone checking the stream. A subtle animation is still a creative choice, not a guarantee of viewer retention or sleep quality.
For the audio, listen to the beginning, middle, and end with headphones. Check for clicks, a sudden rise in volume, silence, spoken material, or a transition that would be uncomfortable when repeated overnight. If you have several visual clips, prepare a playlist rather than manually changing sources during the broadcast.
Rights apply to both halves of this arrangement. You need permission for the rain recording, music, artwork, animation, photographs, and any other material you use. YouTube says live content must comply with its rights requirements, including music rights, and its systems may identify third-party material during a live broadcast. Read the current YouTube copyright guidance and keep copies of licences or permissions that cover live use, the relevant territories, and an archived replay.
A licence does not necessarily prevent an automated match. YouTube notes that authorised third-party content may still require the channel to be added to the rights holder's Content ID allowlist. That is a reason to keep your documentation and confirm the practical requirements with the rights owner before relying on the recording.
Create an OBS scene
Open OBS Studio and create a scene specifically for the sleep sounds channel. Give it a clear name such as Sleep sounds - night rain, so you can identify it if you later create separate scenes for a morning stream or a devotional channel.
The scene is the composition OBS will send to YouTube. It can contain the visual source, the separate audio source, and any optional elements such as a small text label. Build the basic version first. A clock, logo, now-playing label, or subscription prompt can be added later, but each extra element creates another thing to inspect.
Set the canvas to match the shape of the visual you prepared. A landscape video normally belongs on a landscape canvas. If the file has a different aspect ratio, use the preview to check for black bars, cropping, or stretching. Right-click the visual source and use the transform controls to fit it to the canvas rather than dragging it approximately with the mouse.
Create the scene before adding sources so that you know where every item belongs. In the Sources panel, the visual will normally sit above other picture elements. Audio sources do not appear as pictures, but they still appear in the Audio Mixer and need to be identifiable.
This is also a useful point to save the OBS profile and scene collection. If you are new to the software, the guide on creating a 24/7 virtual classroom stream with OBS covers the broader idea of building a repeatable OBS arrangement. The sleep-sounds workflow is narrower: the important distinction here is that the picture and sound are deliberately separate.
Add and loop the visual source
In the Sources panel, choose Media Source and create a new source for the visual file. Browse to the prepared video, then enable the source's Loop property. Check whether Restart playback when source becomes active suits your scene. It can be useful when returning to the scene, but you should test the result rather than assume it will restart in the way you want.
Leave the source visible in the preview and watch it through the end of one cycle. Look for a black frame, a frozen frame, or a change in framing at the join. A loop that looks smooth in a media player can still deserve a check inside OBS, because the source is being rendered as part of the live composition.
If you want a sequence of visual files, use OBS's VLC Video Source instead. It accepts a playlist and includes a Loop Playlist option. VLC must be installed, and the OBS documentation specifies matching 64-bit VLC when you are using 64-bit OBS. This is useful when you have, for example, separate clips of a quiet room, a window, and a dark sky that should repeat in order.
A playlist is not the same as a single edited video. Each clip can have its own transition, frame size, and audio track. If any playlist item contains audio, make sure it does not compete with the separate sleep-sounds source. Mute or remove unintended audio before you rely on the playlist.
Keep the visual source simple if the computer is modest. A high-resolution animated file with complex effects can use more processing than a static image or a gentle loop. You can observe OBS's rendering and encoding warnings while testing, but do not treat a quiet preview as proof that the machine will behave the same way after an overnight run.
Add and loop the separate audio source
Add the sound file as its own Media Source rather than placing it inside the video. Select the audio file, enable its Loop property, and review the playback options shown for that source. The exact choices depend on the source you create, so verify the behaviour in OBS with the file you intend to use.
When the source starts, watch the Audio Mixer. You should see activity when the file plays, and the meter should return to silence or the expected background level during any deliberate quiet section. If the meter never moves, check the file path, source visibility, mute button, and the selected monitoring device.
Use the mixer to set a comfortable level, not to make the stream as loud as possible. A sleep channel may be heard through a phone speaker, headphones, or a bedside device. Listen at a low volume and at the level you expect a viewer to use. A sudden peak in a wave recording can be more disruptive than a generally quiet track.
The audio file can be shorter or longer than the visual file. If the audio is forty minutes and the visual is twenty minutes, the picture may loop twice while the sound continues. That can be perfectly acceptable if both joins are unobtrusive. If the audio ends before the visual and does not restart, the live picture may continue with no sound, so test the full cycle.
For a group of separate sound files, consider whether they should play in sequence or overlap. OBS Media Source is suited to an individual file, while a playlist or edited master file may be easier when you need a controlled order. Do not assume that adding multiple looped sources will create a natural mix. Set each source deliberately and listen to the combination.
If you hear the visual's own soundtrack as well as the dedicated sleep audio, select the visual source in the mixer and mute its audio, or use a version without an audio track. OBS does not decide which source should be the main programme. You make that choice through the sources and mixer.
Balance and test the complete scene
Test the complete scene before connecting it to a public broadcast. Start both sources, leave the preview running, and listen while you watch. Confirm that the visual begins, the dedicated audio begins, and neither source stops unexpectedly when the first loop ends.
Do not claim that the two files are synchronised merely because they started at the same moment. Independent sources can reach their loop points at different times. For a sleep stream, that may not matter, but you need to know what the viewer will experience. If a dark visual briefly changes while the rain continues smoothly, decide whether that is acceptable. If the audio has a clear restart click, replace or edit the file rather than hoping the platform will hide it.
Switch away from the scene and return to it. Restart OBS in a test session. Confirm whether the visual and audio restart, continue, or remain stopped according to your chosen settings. Test after a short period that includes at least one loop boundary for each source. This is a preflight check, not evidence that the same setup will run without attention indefinitely.
Record a short local sample if your computer has enough space. Watch the recording with the preview closed and listen away from the mixer. A recording can reveal a cropped visual, an unwanted source, or a volume problem that is easy to miss while you are configuring the scene.
You should also check the connection and output settings before going live. Use a wired network connection where practical, keep other heavy uploads off the connection, and watch for dropped frames during the test. If you plan to run the stream from a small computer, the guide to reducing power use on a Raspberry Pi running an FFmpeg YouTube stream is relevant to the broader question of local equipment, although this article uses OBS rather than FFmpeg.
Send the scene to YouTube Live
In YouTube Studio, open the Live Control Room and create or select the broadcast. YouTube provides a stream URL and a stream key for the encoder connection. The key tells the encoder where to send the feed and allows YouTube to accept it, so treat it as a private credential. Do not place it in a screenshot, public tutorial, or shared document.
In OBS, open the stream settings, choose the YouTube service if appropriate, and enter the requested connection details. If you use a custom configuration, copy the stream URL and key carefully. A single missing character can prevent the encoder from connecting. If the key may have been exposed, reset it in YouTube before using it again.
Start the stream from OBS and return to the Live Control Room. Check the preview, stream health, picture, and sound before you rely on the public watch page. A local OBS preview only proves what your computer is composing. The YouTube preview shows what has reached the platform.
The stream key and the broadcast are related but not identical. YouTube's Live Broadcasts and Streams API guide explains the distinction between a broadcast event and the audio-video feed sent to YouTube. This matters when you plan a recurring channel, because a new broadcast event may be needed for a planned restart or special programme.
Do not assume that one live session will be archived as a single replay forever. YouTube's current guidance says streams under 12 hours can be automatically archived, while a stream that exceeds 12 hours may not be captured at all. If the replay matters, make a local recording backup and plan how you will handle the archive threshold. A deliberate restart creates a new broadcast and should be explained to viewers if continuity matters.
A stream can continue to show a moving picture while the audio has stopped, so check both parts in the Live Control Room. If the platform displays a placeholder, warning, or interruption related to third-party content, stop and investigate the rights issue rather than repeatedly reconnecting.
Keep the local setup running
A local OBS arrangement makes your computer, electricity supply, files, operating system, and upload connection part of the broadcast. The computer may sleep, install an update, lose its network route, overheat, run out of storage, or restart after a power interruption. None of these risks is removed by enabling a source loop.
Disable automatic sleep and shutdown for the period in which you intend to broadcast. Keep the laptop plugged in, but check its power settings so closing the lid does not stop the session. Prevent automatic updates from restarting the machine during the planned run, while still applying important updates during a controlled maintenance window.
Keep the media files at the paths OBS expects. If you use an external SSD, treat it as optional removable storage rather than a reliability guarantee. A loose cable or drive sleep can make a perfectly configured source unavailable. A local copy on the machine can be easier to operate, provided there is enough storage and a backup exists elsewhere.
Monitor the public feed, not only the OBS window. You can use a separate phone or computer to check the watch page, but remember that monitoring on the same machine may hide a local playback problem. If your connection drops, YouTube may show that the stream is reconnecting or offline. The guide on recovering an FFmpeg YouTube live stream after a network drop describes a related recovery concern; the general lesson also applies here: decide what you will do after a failure before leaving the channel overnight.
For a local setup, write down the restart steps. Include the order for opening OBS, checking the scene, starting the stream, confirming the YouTube preview, and verifying audio. Keep the stream key out of the written checklist. A simple procedure helps when someone else needs to restore the channel at an inconvenient time.
If you do not want to keep a personal computer online, hosted playout is another operating model. Some providers describe a workflow in which you upload files, arrange a playlist, add an RTMP destination, and run the programme without your computer. That description is a vendor's account of its own service, not an independent uptime measurement. Compare current cost, storage, stream limits, restart behaviour, YouTube compatibility, and rights obligations directly before choosing it.
A hosted option removes the local machine from the daily task, but it does not remove responsibility for the media, YouTube connection, archive planning, or rights. A local OBS setup is better when you need hands-on scenes and can maintain the equipment. Hosted playout is worth considering when the main problem is keeping a personal computer powered and connected.
When the repeated need is a prepared file rather than live scene control, StreamNeo removes the need to leave your own computer running by taking an uploaded video, a YouTube stream key, and the prepared channel content into a monitored cloud broadcast. It is still your responsibility to confirm that the file contains the picture and sound you want, and to check current YouTube rules and rights before publishing.

FAQ
Can I use a short visual and a longer sleep-sounds file?
Yes. Add them as separate OBS sources and enable the relevant loop settings. The visual may repeat several times while the audio continues, so watch and listen through the loop points to make sure both restarts are acceptable.
Does OBS automatically synchronise the audio and video files?
No. OBS can compose separate sources, but you should not assume that independent files will remain synchronised or restart in lockstep. Test the complete scene after starting it, switching scenes, and restarting OBS.
Can YouTube archive a 24/7 sleep stream as one replay?
YouTube says streams under 12 hours can be automatically archived and warns that a stream exceeding 12 hours may not be captured at all. If a replay matters, keep a local recording backup and plan deliberate broadcast restarts rather than relying on one uninterrupted archive.
Is a local computer guaranteed to run the stream all night?
No. Power, sleep settings, updates, files, hardware, and network conditions can interrupt a local encoder. Test the setup, monitor the public feed, and decide whether local OBS or hosted playout better fits the attention and equipment you can provide.
