A Beginner's Guide to Field Recording with Your Phone

Field recording sounds like it requires a studio-grade setup. It doesn't. The phone in your pocket has a microphone that's more capable than you might think. Here's how to get started.

Why your phone is enough

Modern smartphones have surprisingly good microphones. They won't match a dedicated field recorder in dynamic range or noise floor, but for capturing the character of a place, they work.

What matters more than your equipment:

• Where you stand. A few steps in any direction can completely change what you hear.
• How still you are. Handling noise is the enemy. Set your phone down or hold it very still.
• How long you record. Give it at least 5 minutes. Real environments need time to breathe.

Apps we recommend

You don't need anything fancy. These free or low-cost apps record in high quality and export WAV files, which is what we look for:

• Voice Memos (iOS) — already on your phone. Set it to Lossless in Settings > Voice Memos > Audio Quality.
• Recorder (Google Pixel) — records in high quality out of the box. Other Android phones ship similar built-in apps.
• Dolby On (iOS / Android) — free, records in high quality with optional noise reduction you can turn off.
• Rode Reporter (iOS / Android) — free, clean interface, supports WAV export and manual gain control.
• RecForge II (Android) — records in WAV/FLAC, supports external mics, and gives you control over sample rate and bit depth.

Avoid apps that only export to low-bitrate MP3. If it lets you choose WAV or Lossless, you're set.

Before you press record

1. Turn off notifications. Airplane mode is your friend. One ping can ruin a 20-minute recording.
2. Listen first. Stand in your spot for a minute before recording. What do you actually hear? Is there a layer of sound you didn't notice at first?
3. Find your angle. Face the direction where the most interesting sound is coming from. Small adjustments matter.

What to record

The most interesting recordings aren't silent ones. They're alive. Look for places where things are happening:

• A weekend market. Voices overlapping, bags rustling, someone calling out prices. The texture of commerce.
• A playground in the afternoon. Kids shouting, swings creaking, the distant hum of the neighbourhood around it.
• A train station platform. Announcements, footsteps, the swell of an arriving train and the silence after it leaves.
• A rainstorm from a doorway. Water hitting concrete, cars passing through puddles, the shift in rhythm as it gets heavier.
• A café at lunch. Cutlery, conversation, the espresso machine, a door opening and closing.
• A river or coast. Water moving over stones, wind through reeds, birds calling across the surface.
• A neighbourhood at dusk. The transition from daytime activity to evening quiet. Doors closing, bikes passing, someone's TV through a window.

The goal isn't silence. It's capturing the honest acoustic character of a moment. A place with people in it, weather around it, life running through it. These are the recordings that matter.

Tips for better recordings

• Wind is your biggest enemy. If it's windy, shield your phone or find shelter. Even a cupped hand over the mic helps.
• Get close to surfaces. Rain on a metal roof sounds different from rain on leaves. Put your phone near the surface you want to hear.
• Don't move. Once you start recording, stay still. Every shift of your hand is audible.
• Record longer than you think you need. Aim for at least 10 to 20 minutes. You can always trim later. You can never add back the moment you stopped too early.
• Avoid handling your phone. Prop it against something or set it on a stable surface. Your fingers on the case are louder than you think.

What to do with your recording

Listen back with headphones. You'll hear things you missed in person. The distant conversation, the bird you didn't notice, the way the traffic ebbs and flows. If the recording captures the feeling of being there, even roughly, it's worth keeping.

When you're ready, consider joining the Open Atmos collective. We welcome recordings from any device, as long as they're honest.
