Mix rain as a continuous bed and thunder as a separate, restrained layer. Overlap and crossfade the rain clips to hide loop seams, then monitor the finished output for abrupt changes and clipping. There is no established sleep-specific loudness target or required rain-to-thunder ratio, so judge the balance by listening rather than following a made-up number.
Build the mix from separate rain and thunder tracks
Keeping the sounds on separate tracks lets you adjust the steady rain independently from each thunder event. Make rain the continuous background; place thunder less frequently and at a level that adds atmosphere without startling the listener. The right balance depends on the recordings and the intended listening experience—official guidance cited here does not prescribe a ratio, thunder frequency, or sleep-stream loudness target.
You can assemble the tracks in a multitrack audio editor or mix sources in OBS. Adobe Audition is one documented example of an editor that supports clip-level volume changes, fades, and crossfades; you do not need that specific software to use the technique. Adobe Audition: match, fade, and mix clip volume.
Make the rain loop sound continuous
- Find a repeatable section. Choose a rain segment without a conspicuous impact, change in texture, or sudden level shift near its start or end.
- Overlap repeated clips. In a multitrack editor, place the next rain clip before the previous one ends. Apply a crossfade across the overlap so one clip fades out as the next fades in. In Adobe Audition, the overlap determines the crossfade duration.
- Fade the full mix in and out where needed. Use fades at the beginning or end of a recording when appropriate; for a continuous live stream, make sure the loop itself does not repeatedly fade to silence.
- Listen across the boundary. Preview multiple repetitions at normal listening level. Listen for a sudden change in rain texture or loudness, a gap, or a repeated sound that makes the loop obvious. Adjust the edit or overlap and audition again.
There is no single ideal loop length established by the cited guidance. The practical test is whether the transition remains unobtrusive over repeated playback.

Balance thunder and rain without clipping
- Monitor the signal while adjusting. In OBS, listen to the signal through a monitoring device as you change levels. Pay particular attention to the loudest thunder peaks, not only the steady rain.
- Keep the output below 0 dBFS. OBS identifies 0 dBFS as the digital maximum and warns that audio at or above it can clip in a stream or recording. Use the OBS peak-hold meter to notice brief peaks that might otherwise be easy to miss.
- Treat OBS meter references as references, not sleep targets. OBS documentation gives -20 dBFS as its meter alignment level and -9 dBFS as its permitted maximum reference. Those values describe OBS meter conventions; they are not recommended loudness settings for rain or thunder.
- Record and listen back before going live. OBS recommends recording a session and listening to it before streaming. Check that thunder remains comfortable over the rain and that the loop transition does not draw attention.
OBS says its audio processing uses floating-point calculations and can process audio louder than 0 dBFS internally. That does not remove the need to keep the streamed output below the clipping ceiling.
Check stereo routing and playback
OBS Studio defaults to stereo. Confirm that both left and right channels of the intended mix are audible. OBS describes mono audio as heard in both left and right channels; check that a mono source has not accidentally been routed to just one side. For a practical preflight, listen to the actual OBS recording or stream output on headphones and a small speaker or phone, and confirm that audio is present. The extra playback-device check is a useful listening test, not an OBS requirement.

Preflight the stream
- Play the rain loop through several repetitions and listen for gaps, level changes, or an obvious repeated event.
- Check the loudest thunder peaks in OBS and keep the output below 0 dBFS.
- Monitor the signal, then record and listen back before going live.
- Confirm that both intended stereo channels are audible, or that mono audio reaches both sides.
- Verify that you have rights for both the live stream and its archive, and include any required attribution.
