Automatic track changes happen in your playout setup or encoder, before the audio reaches YouTube. For a small local setup, you can use an OBS VLC Video Source with a playlist and Loop Playlist enabled; YouTube receives the resulting live feed, not a song queue of its own.
That can be enough for a simple radio loop, but it does not make the whole channel self-running. You still need to check that the files advance, the stream stays connected, the picture remains valid, and you have the rights needed to broadcast each recording.
Identify the source that controls track changes
Start by finding where your audio enters the scene. In OBS, a radio setup might use a VLC Video Source loaded with local music files, a media source for a single file, a browser source, or audio coming from another application. The place to configure track order and repeat behaviour is the source or playout tool that actually holds the queue.
For a local-file playlist, one documented route is to add a VLC Video Source in OBS, select the intended audio files in playlist order, and enable Loop Playlist. The exact labels and controls can vary by OBS, VLC and operating-system version, so treat a guide as a route to verify in your current interface, not as a promise that every menu will match. The iTechGuides walkthrough for looping an OBS music playlist describes this local-file approach.
YouTube is downstream. You configure an encoder with YouTube's stream URL and stream key, then send it the composed audio-video programme. YouTube's encoder setup instructions explain that connection process. A playlist in OBS is not the same thing as YouTube's HLS media playlist, which is a transport format for delivering stream segments rather than a creator-facing queue of songs.
If you are choosing between a local playlist and hosted playout, consider who needs to maintain the queue, whether a desktop must stay running, what monitoring and recovery controls you have, and how you will make transitions and visuals. A local setup is understandable and gives you direct access to the files. A scheduled cloud playout or a remote host may suit a station that needs remote operation, but you will need to verify its actual features rather than assume a category of product includes them. For a broader look at remote radio playout, see how cloud radio playout can feed YouTube Live.
Listen for one problem before adding filters
Before adjusting audio, play the playlist and listen for a specific fault. Is one recording much louder than the next? Does speech or a devotional introduction sound buried under the music? Is there a hum, hiss, harsh peak, or abrupt silence? Write down what you hear and where it occurs. A filter is useful only if it addresses a problem that is actually present.
Listen through the full sequence, including the quiet opening of a track, its loudest passage, its ending, and the next track's start. A song can be restrained for the first minute and much louder when percussion enters. Ambient music may depend on a wide, quiet texture, while a bhajan can have a prominent vocal and a strong rhythmic section. A processing choice that seems helpful during one chorus may make the next intro feel unnaturally loud or suppress details that belong in the recording.
Keep the source and the listening point clear. If the sound is already distorted in the file, an OBS filter cannot restore missing detail. If an application is producing the wrong level before OBS receives it, adjust that application or its source routing first. For uneven track-to-track levels, preparation may be the better place to work: this guide to normalising audio across playlist files covers a different stage from applying a live filter to the source.
Do not begin with a chain copied from a microphone tutorial. A microphone filter is often intended to manage a person speaking close to a mic; music contains arrangements, transients and dynamics that can react quite differently. A gate that closes during a speaker's pause may cut the quiet tail of a song. Compression that makes speech more even may flatten a musical build. Decide from listening, not from a preset's label.
Open the filters for the right OBS source
In OBS, open the source's Filters window for the audio-bearing source you intend to change. Check the source name before adding anything: a filter on a VLC Video Source will affect that source, while a filter on a global output or another source can affect more of the mix than you meant to change. If the scene has separate music and voice sources, keep track of which one is selected.
First listen with filters disabled or note their existing settings. This gives you a reference and helps distinguish a source fault from an adjustment introduced earlier. If several sources feed the programme, mute or solo them one at a time where practical to locate the sound. Make one change at a time, then compare the result with the original. If you alter several controls together, it becomes difficult to tell which change helped or caused a new problem.
A practical test scene can help. Keep the picture simple, load a short representative playlist segment, and check that the source produces sound before sending a public broadcast. Include at least one quiet passage and one full musical passage in the test. Interface names and available filters can change between releases, so consult current OBS documentation if a control is not where you expect it rather than following an old screenshot blindly.
Remember that a source filter operates on the signal OBS receives from that source. It does not change the underlying audio file, fix the ordering of the playlist, or repair a broken YouTube connection. If the source is not advancing, solve that playout issue separately; the automatic video playlist setup with FFmpeg is another workflow, not a setting inside the music source's filters.
Add only processing that fits the fault
For a persistent low-frequency hum or rumble, a high-pass filter may reduce unwanted energy below the useful range. Use restraint: bass instruments, low vocal notes and the body of drums can also occupy that area. If the music becomes thin, loses weight, or a quiet intro changes more than intended, back the adjustment off or remove it.
For a single source that is simply too loud at all times, reduce its gain rather than compressing the entire mix. If a source varies widely and occasional peaks are troublesome, a compressor may help manage peaks, but its threshold, ratio and timing need to suit the material. Aggressive compression can make a track tiring, bring up hiss between notes, or reduce the contrast that gives a passage its shape. It is not a method for guaranteeing equal loudness between different recordings.
A limiter can help prevent peaks from exceeding a chosen ceiling in the signal path, but it cannot make every track sound equally balanced or undo clipping that occurred earlier. Listen for pumping, flattened transients or a sudden change in texture. A noise gate or expander is usually a poor default for a music playlist: quiet pads, reverb tails, room ambience and soft intros may fall below its threshold and be cut or made to flutter.
If the real issue is that one file is much quieter than another, consider correcting the files before loading them into the playlist, then audition the edited versions. That lets you handle an outlier without forcing a live filter to treat every track identically. Leave a source unfiltered when you cannot identify a repeatable fault that the filter improves. Processing is optional; a clean, sensibly prepared source is a valid outcome.
The trade-off is between intervention and preserving the recording. A filter can solve a narrow fault at its source, but it adds another setting to remember and another possible cause if the sound changes. Keep notes of the source, the setting and the passage used to judge it. If you cannot describe what improved in a listening comparison, remove the filter rather than keeping it because a tutorial recommended it.
Check quiet passages and transitions
After each adjustment, replay the quietest section you can find. Listen for a cut-off reverb tail, a gate opening late, noise suddenly swelling between phrases, or music that has lost its low end. Then listen to the loudest section. Watch for audible distortion, brittle peaks, pumping, or a change that makes percussion and vocals feel cramped. Filters can affect those sections in opposite ways, so checking only the chorus is not enough.
Next listen across a track boundary. A playlist can move cleanly from one file to another while the perceived level or texture jumps sharply. Test a quiet intro after a loud song, a track with a long fade, and any transition where the playlist might leave a gap. If OBS offers a transition or source behaviour relevant to your chosen setup, test it in the actual scene; do not assume a setting intended for video transitions will create the musical crossfade you want.
Keep the queue intentional. Confirm the order, remove duplicate or incomplete files, and make sure the playlist's repeat behaviour is what you expect. For a station that needs different rotations by time or day, a simple looping list may not provide scheduling controls; compare that limitation with the work involved in maintaining a more capable playout workflow. Neither a playlist loop nor a filter makes the stream immune to a stopped computer, power loss, network trouble, missing media, or a dropped connection.
A small checklist is more useful than trying to judge everything from memory:
| Check | What to listen or look for | If it fails |
|---|---|---|
| Quiet intro | Does the opening remain audible and natural? | Revisit gates, expansion or excessive noise reduction. |
| Loud passage | Are peaks clear without obvious distortion or pumping? | Reduce source level or moderate dynamics processing. |
| Track boundary | Is there a sudden level jump, gap or clipped fade? | Review file levels, ordering and transition behaviour. |
| Playlist loop | Does playback return to the intended first item? | Check the source playlist and its loop setting. |
| Picture and feed | Does the scene remain present while audio changes? | Check the OBS scene and encoder output separately. |
Use the table as a listening prompt, not as a technical certification. Your music catalogue and room playback will differ from someone else's, and there is no universal filter setting that makes all sources behave alike.
Listen to the encoded or live result
Monitoring inside OBS is not the last check. The signal that reaches YouTube has passed through the encoder and the streaming path, so confirm the actual output after starting a private test or an appropriate test stream. Listen on another device if available, and compare the same quiet passage and transition you used while adjusting the source. Do not rely only on the sound from the computer that is playing the files.
YouTube's encoder guide covers connecting a stream key and beginning the feed. Once YouTube reports that it is receiving the stream, check that audio is present, the image remains valid, and the playlist continues to advance. A single successful track change proves only that the queue advanced once; let the test reach a loop boundary if repeating is central to the plan. Interface status indicators are useful, but they do not replace listening.
For a continuous channel, decide who will notice if the desktop sleeps, OBS closes, a file becomes unavailable, or the internet connection drops. If the local computer is the playout host, its power and network are part of the broadcast chain. StreamNeo removes the specific burden of keeping your own computer running for an uploaded-file stream: you upload the video once and the cloud broadcast runs with your computer off, with monitoring and automatic restart if it drops. It is YouTube-only, and it does not remove your responsibility to check the programme, rights and output.
YouTube also scans live streams for matches to third-party content. Its copyright guidance for live streams says a match may result in a placeholder, warning, interruption or termination if the issue is not resolved. A licence may not by itself prevent interruption if the rights owner requires the channel to be allowlisted in Content ID. Check the current YouTube guidance and your rights arrangements before relying on any recording for a public live broadcast.
If the stream drops repeatedly, separate audio troubleshooting from connection troubleshooting. Listen for whether the source itself stopped, then check OBS and YouTube's receiving status. The guide to diagnosing repeated YouTube Live disconnects on Linux focuses on a different failure point: connection behaviour, rather than track changes or audio processing.
For a new account or a changed encoder setup, confirm the channel is enabled for live streaming and that the stream key belongs to the intended event. YouTube's setup guidance notes that initial live-stream activation may take time, so do not make the first verification at the moment you expect the station to go live. Check current official instructions for the account and encoder you are using.

FAQ
Can YouTube change tracks automatically from a song list?
For the workflow described here, the playlist is maintained in OBS or another playout tool and YouTube receives the encoder's programme feed. YouTube's HLS playlist is part of stream delivery, not a creator-facing music queue. Set up and test track order before the feed reaches YouTube.
Do I need an OBS filter on every music source?
No. Add a filter only when you hear a specific problem that it addresses, and compare the filtered result against the original. A setting that suits one recording can affect another track's quiet intro, fades or dynamics differently.
Does Loop Playlist make a YouTube stream run continuously?
It repeats the source playlist, but does not guarantee that the encoder, computer, power, network, media files or YouTube connection will keep working. Monitor the actual stream and plan how you will respond to a stoppage. Check track transitions and a full loop before leaving the setup unattended.
Can I stream any music file if I own a copy?
Owning a copy is not necessarily the same as having rights for public live streaming. YouTube scans live streams for third-party content, and a rights owner may require Content ID allowlisting. Check the current official policy and your permissions for every recording before broadcasting.
