High quality rain sounds: 7 things that separate real from fake
Search for rain sounds and you will find thousands of hours of them. Most are fine for five minutes. Far fewer hold up for a whole night, when your brain has nothing to do but listen. High quality rain sounds are the ones that still sound like weather at 3am, not like a file.
Here are seven things to listen for. Once you know them, you will spot cheap rain in seconds.
1. No audible loop
The most common flaw by far. A short clip, often 30 seconds to a few minutes, is repeated end to end. You might not notice consciously, but after a while you start to anticipate the same splash, the same gust, the same gurgle. Some people find it maddening once they hear it.
Listen for: a distinctive sound that comes back on a regular schedule. Time it. If it returns every 60 seconds, you are listening to a loop.
High quality rain either uses very long recordings or builds the rain continuously so nothing comes round in the same order. We cover this in detail in rain sounds without loops.
2. No landmarks
Even a long recording can have a few memorable moments: one loud splat, a door, a car passing in the distance, a bird, a cough. These are what your ear latches onto. In a long track you hear the car pass at minute 14 and wonder why there is a car in your rainforest.
Listen for: anything that is not rain or thunder. Voices, engines, birds, dogs, planes, and sudden jumps in level.
3. Real space
Cheap rain sits in a narrow band between your ears. Good rain has width, depth and height. On headphones it should feel like rain is around and above you, not inside your head. On speakers it should come from the room, not from the boxes.
Listen for: whether you can point to where things are. Can you hear rain behind you? Above you? If everything comes from the same place, it is a flat recording. More in surround rain sounds.
4. Detail on surfaces
Rain is not one sound. It is millions of drops hitting glass, metal, fabric, leaves and puddles, and each surface rings differently. Glass ticks. A metal roof pings and drums. Tent fabric pats. Leaves rustle and shed big drops. Water in a gutter makes a rising plink.
Listen for: whether you can tell what the rain is landing on. If it is just undifferentiated hiss, it could be any noise generator with a filter on it.
5. Natural variation
Real rain never holds perfectly steady. It thickens for a minute, lightens, picks up again. That slow drift is part of why rain sounds alive. Rain that sits at exactly the same density for an hour starts to sound like a fan.
Listen for: gentle changes in intensity over a few minutes. Not sudden jumps, which are usually edits or level problems, but a slow breathing in and out.
6. A clean recording
Field recording rain is hard. Microphones pick up wind rumble, the recordist's movements, distant traffic and electrical hum. Rain is also loud and dense, which pushes cheap recorders into distortion.
Listen for: low rumble that is not thunder, a constant hum or whine, harsh crackle on loud drops, and a dull, muffled top end that suggests heavy noise reduction.
7. Even level and gentle thunder
At night, the worst thing a rain track can do is suddenly get louder. Some tracks are mastered loud with thunder that clips or jumps out of nowhere. Others are compressed so heavily that the rain pumps up and down around every rumble.
Listen for: whether the overall level stays comfortable for an hour, and whether thunder rolls in naturally instead of slamming. See thunderstorm sounds for sleeping.
What about bitrate?
People often ask whether they need lossless or hi-res rain. Bitrate matters a little, but much less than the seven points above. A great recording at a good compressed bitrate beats a poor recording in a lossless file every time. We dig into it in lossless rain sounds.
How Retro Rain stacks up
We built Retro Rain around this list:
- Loops: on headphones, long real recordings play untouched in 30 second chunks that are reshuffled on every pass, so a 12 minute recording never comes round in the same order. On surround, rain is rebuilt continuously from grains of recording, and SYNTH generates every drop live.
- Landmarks: recordings are screened for passing cars, voices, birds, knocks and level jumps, and the memorable moments are cut out and patched with quiet rain.
- Space: sounds are placed around and above you on headphones and get their own discrete channels on 5.1 and 7.1.
- Surfaces: each place has its own drops on glass, metal, tent fabric and leaves, placed where they would land.
- Variation: the rain rate slowly wanders by about ten percent either way, with the odd lull or burst.
- Level: recordings are matched in loudness and a limiter catches the rare loud drop.
Press PLAY, pick a place and listen for the seven things above. Then compare it with whatever you used last night.
