A pop at the end of an ASMR recording usually comes from the audio edit itself, not from OBS. Repair the transition in an audio editor, export the finished file, and then enable repeat playback in OBS.
These are separate jobs. OBS can play a prepared file again after it finishes, but its Loop setting does not make a discontinuous ending and beginning join smoothly.
Identify Whether the Pop Is at the Loop Point
First establish when the sound occurs. Listen to the recording from near its ending through the beginning again, rather than playing it only once from start to finish. If the pop appears at the same moment on every repeat, the file boundary is the main suspect.
You can make this check before opening OBS. Place the playhead shortly before the end, listen through the final sound, then continue immediately from the start. Repeat that test several times. A seam that is easy to miss when you are concentrating on the recording may become obvious when the same transition happens repeatedly.
There are other possible causes. A monitoring device, audio driver, scene change, or source restart can create a sound that is not present in the recording. To separate these cases, open the file in an audio editor and listen to the end followed by the beginning. If the pop is audible there, OBS is not the part that needs repairing.
If it happens only in the live scene, check the source and monitoring path separately. Make sure another audio source is not starting at the same time, and check whether the sound is produced when the media source reloads rather than when the file reaches its end. This article covers a prepared recording that repeats, not a live microphone or live sound feed being restarted.
For a longer workflow around repeatable recordings, the guidance in how to start a 24/7 Hindi radio channel on YouTube is relevant because the same distinction applies: a reliable broadcast depends on both a suitable media file and dependable playback.
Inspect the Waveform at the Edit Boundary
Open the source file in an audio editor such as Audacity and inspect the final samples and the first samples together. Zoom in far enough to see the waveform around the edit boundary. You are looking for a sudden change in level or direction where the file jumps from its last sample to its first sample.
A clean-looking waveform is not enough on its own. Listen to the material as well. A soft room tone may look irregular but still join naturally, while a small waveform jump during a close-up whisper can be very noticeable. ASMR recordings also contain delicate details such as breath, cloth movement, tapping, and room ambience, so a technically tidy cut can still sound like an interruption.
A useful first adjustment is to move the edit points. Look for a compatible, low-amplitude part of the recording where the ending can meet the beginning. An edit near a zero crossing can reduce the risk of an audible click because the signal is passing through zero amplitude at the cut. It is not a guarantee, however.
Stereo audio needs particular care. The left and right channels may cross zero at different points. A position that looks suitable in one channel can still create a discontinuity in the other. Inspect both channels and listen in stereo before deciding that the boundary is fixed.
Do not remove a quiet tail simply because it looks empty. Room tone can be part of the continuity of an ASMR recording. Cutting it away may create a new jump between an active sound and digital silence. Instead, compare the end and beginning as one repeating passage.
The goal at this stage is to decide which of two edits is appropriate:
| Situation at the boundary | First approach | What to listen for |
|---|---|---|
| Ending and beginning have similar room tone and level | Move the cut to compatible low-amplitude points | A click, sudden level change, or change in stereo image |
| The two sections do not meet naturally | Overlap them and crossfade | A dip, swell, doubled sound, or change in texture |
| One channel still jumps at the cut | Inspect the channels separately and adjust the boundary | A click that remains in the left or right side |
| The seam sounds clean in the editor but not in playback | Export another format and test the actual file | A gap or altered start caused by the playback format |
There is no universal edit position that works for every whisper, brush, rain bed, or tapping track. Treat the waveform as evidence for where to investigate, then let repeated listening decide whether the transition works.
Edit the Transition in an Audio Editor
If moving the boundary is enough, make the smallest useful edit. Select a short section around the proposed end and beginning, place the edit at compatible waveform positions, and play across the boundary. Keep the original file untouched so that you can return to it if the new seam changes the character of the recording.
When a direct join remains audible, overlap the ending and beginning and crossfade them. A crossfade means that one section fades down while another fades up. In practice, you place the outgoing tail and incoming start on overlapping sections or tracks, apply the fades, and audition the combined result as a repeating loop.
The important point is not to choose a crossfade by habit. The transition must suit the material. If the end contains a long exhale and the beginning contains a close whisper, blending them may produce an unnatural swell or a doubled voice. If both sections contain steady room tone, a blend may be less noticeable. A click can disappear while the texture still becomes wrong.
Crossfade curves also involve a trade-off. A constant-gain crossfade can avoid clipping when the source audio itself is not clipped, but the overlap may dip in level. A constant-power curve is intended to reduce that dip, but it can raise the peak. Listen for both effects rather than assuming one curve is always correct.
Check the transition at normal listening level and at a quieter level. A seam that seems acceptable when loud may become an obvious change in room tone when played quietly. Conversely, increasing the volume to hunt for a click can make a natural change seem more severe than it will be during the broadcast.
Audacity documents the mechanics of fades and crossfades in its Fade and Crossfade manual. Use that documentation for the current control names and behaviour, particularly if the editor's interface has changed since you last used it.
Keep the recording's character intact
Do not process the whole file merely because the loop boundary is troublesome. Extra noise reduction, compression, or equalisation can change breathing, surface noise, and room tone throughout an ASMR recording. If the pop is local to the seam, start with a local edit.
If you need to remove a short unwanted event at the end or beginning, leave enough natural ambience around the edit for the crossfade to sound believable. A technically silent gap can be more distracting than a quiet room tone that continues across the repeat.
Check Stereo Channels and Levels
Before exporting, check the left and right channels separately as well as together. A pop may be obvious in one channel but less apparent in the combined stereo view. The two channels can also have different waveform shapes at the same time position, so moving the edit to a zero crossing in only one channel may not solve the problem.
Listen for changes in stereo position at the transition. A brush that sits on the left at the end and returns on the right at the beginning may sound like an intentional movement, but a sudden shift in room tone can draw attention to the loop. If the recording is meant to feel continuous, the acoustic space should not appear to jump.
Then watch the level through the overlap. The crossfade should not create a sudden dip that resembles the room going quiet, or a swell that resembles a new sound arriving. A higher peak is also worth checking because it may become more apparent after the file is played through the streaming chain.
Do not turn this into a search for a magic level or crossfade setting. The correct result depends on the source recording, the sounds at its two ends, and the way those sounds overlap. Keep the change as small as possible while removing the seam.
If you use headphones for this inspection, treat them as a way to hear the boundary more clearly, not as a fix. Test the exported file on the listening setup you normally use as well. A loop that sounds natural in headphones may reveal a level change on a speaker, and the reverse can also happen.
This is also a good point to check that the source is not already clipped near the edit. A fade can manage a transition, but it cannot restore detail that was distorted during recording. If the original ending is damaged, choosing a different section or re-recording that part may be cleaner than trying to hide it.
Export and Audition the Full Loop
Export the edited file as a new file with a clear name, then listen to that exported file rather than relying only on the editor project. The project may contain fades, track relationships, or playback behaviour that are not represented exactly in the final file.
Audition the full loop by listening through the end and into the beginning repeatedly. Use the same start and end conditions that you intend to use in OBS. If the recording begins with a short fade-in or ends with a tail of room tone, include those parts in the test. The objective is to hear several boundaries, not just confirm that the middle of the file sounds good.
Audacity's timeline documentation describes loop playback and selecting a loop region for repeated listening. Its timeline guidance can help you move the region while auditioning the seam. Adjust the boundary while the passage repeats, because a visually neat start point may not be the best-sounding one.
Test the exported format in the software that will actually play it. Audacity notes that some applications can introduce a small amount of silence when playing MP3 files. If a gap matters for your loop, try WAV, FLAC, or Ogg Vorbis and audition the result again. Choose a format that your intended source accepts and that you have checked in the real playback path.
The file extension alone is not proof that the loop is ready. Load it into a normal media player, jump close to the end, and listen through the start. Then place it in the source you will use for the stream. Playback software can handle the file differently from the editor.
Keep both the original and the loop-ready export. If you later change the visual video, adjust the loop length, or discover that a repeated sound has become tiring, you can make another edit without degrading the source through repeated exports.

Enable Looping on the OBS Media Source
Once the audio transition is clean, add the prepared video or audio-bearing file to OBS as a Media Source. In the source properties, enable the Loop option so the file plays again after playback completes. The control is a playback instruction, not an audio repair tool.
The OBS Media Sources documentation describes the Loop control as specifying whether the file should play again once playback has completed. That is exactly what you need after the file has been edited: OBS repeats the finished file, while the editor has made the boundary suitable for repetition.
If the file includes video, check the other source behaviour as well. Decide whether the source should restart when it becomes active, whether it should close when inactive, and whether the source's dimensions and audio are correct for your scene. These controls affect how the media source behaves in OBS, but none of them changes a discontinuity in the file.
A VLC Video Source is another OBS route for playlists, but it requires VLC. OBS notes that 64-bit OBS requires 64-bit VLC. Use this option when you genuinely need playlist handling rather than adding it as a workaround for a pop in one prepared file. For a single loop, a Media Source is usually the simpler place to start.
If you are running OBS on a computer for a long period, source configuration is only one part of the risk. Power, network interruptions, system updates, and application restarts can all affect an overnight broadcast. The advice in how to keep an FFmpeg YouTube stream running on Airtel Broadband in India covers a different streaming method, but its practical lesson also applies here: test the complete operating setup rather than trusting one setting.
StreamNeo removes the need to leave your computer running for this particular prepared-file workflow: upload the finished video once, add your YouTube stream key, and let the channel repeat it while the service monitors and restarts the broadcast if it drops. You still need to repair and audition the audio seam first, because cloud playback cannot make a discontinuous recording seamless.
Test Repeat Playback Before Streaming
Do a local test before starting the public broadcast. Add the exported file to the actual OBS scene, enable Loop, and monitor enough playback to hear more than one boundary. Start the test near the end if the file is long, but also let the source run from its beginning so you check the first transition under normal conditions.
Watch the source as it finishes. Confirm that OBS starts the file again, that the audio does not disappear, and that the video does not freeze or restart in an unexpected scene state. If the loop is part of a larger scene, listen for other sources that may overlap at the same moment.
Make a short recording of the OBS output if possible and review that recording at the seam. Monitoring the source in OBS tells you what you hear at the time, while a recording gives you a way to inspect what was actually sent through the scene. This is especially useful when filters, monitoring, or multiple audio tracks are involved.
If you hear a pop in this test, return to the file and compare it with the original. If both have the pop, edit the boundary again. If only OBS has the sound, investigate source activation, audio filters, scene changes, and the playback format. Do not keep changing the Loop checkbox in the hope that it will repair the waveform.
Check the test after a complete repeat, not only after manually moving the playhead. A manual seek can produce a different sound from natural playback reaching the end of the file. You want to know what the audience will hear when the source completes normally.
For a channel that depends on prepared recordings, document the working file, format, OBS source settings, and test result. If you replace the recording later, repeat the same check. A new edit can introduce a new seam even when the previous version was quiet.

FAQ
Can OBS remove the pop from my ASMR loop?
No. OBS can repeat the file when playback completes, but it does not repair a sudden waveform change at the file boundary. Edit and audition the recording first, then use the Media Source Loop setting for repeat playback.
Should I always cut at a zero crossing?
A zero crossing can reduce the risk of a click, but it is not a guarantee. Stereo channels may cross zero at different positions, and the surrounding ASMR texture may still make the edit audible. Inspect both channels and listen to the actual transition.
Is a crossfade always better than moving the edit?
No. Moving the edit is often cleaner when the ending and beginning already have compatible tone and level. A crossfade can help when they do not join directly, but listen for a dip, swell, doubled sound, or change in texture.
Which export format should I use for a seamless loop?
Test the exported file in the software that will play it. If an MP3 introduces a small gap in that playback path, try WAV, FLAC, or Ogg Vorbis and audition the result again, provided the format works with your source.
