Fields
Audio Recorder
Field Recorder
Fields is a portable iOS field recording app designed for capturing, organizing, and editing sounds in one place. Record new material wherever you are, import existing audio files, attach photos, location, and notes, and apply useful edits directly within the app. Whether you are collecting ambiences, textures, found sounds, percussion, or impulse responses, Fields keeps your recordings organized and ready to use.
Fields is available on the App Store for iOS and iPadOS (Standalone App).
Recording
Fields makes it easy to capture sounds in any situation, without the need to carry a dedicated field recorder or manage SD cards. Start a new recording in seconds, or append new material to an existing recording as your collection grows.
You can adjust the recording input level with Rec Gain. On devices that support hardware input gain, this control switches to HW Gain and adjusts the device’s physical input gain directly. Otherwise, it applies digital gain before the audio is written to the recording.
Pre-Roll
Fields can continuously capture a short pre roll buffer before recording begins, helping you save sounds that happen just before you press Record. Set the buffer length in the Settings menu, then hold the Record button and swipe up to include the pre roll audio in a new recording.
The pre roll buffer can be set to up to 20 seconds.
Editing
Fields includes a practical set of editing and processing tools, so recordings can be refined directly after capture, without transferring files to another app. Select a portion of the waveform to copy, cut, crop, reverse, and fade, then apply processing only to that section or to the entire recording.
Adjust levels with Gain / Normalize, shape the sound with the built in Filter, or transform recordings using Pitch / Speed controls.
Trim Silence automatically detects and removes unwanted quiet areas, with controls for threshold, tolerance, and smoothness to achieve natural results.
For recordings made in noisy environments, Noise Reduction can learn a noise profile from a selected region and reduce background noise while preserving useful detail.
Together, these tools make Fields useful not only for capturing sounds, but also for quickly cleaning, shaping, and preparing recordings while you are still in the field.
Location and Map
Fields can automatically geotag your recordings, so you can remember exactly where each sound was captured. If needed, you can also change the location later.
The built-in map lets you browse your recordings by place, making it easy to return to a location, rediscover sounds from a trip, or organize your collection around the environments where they were recorded.
Why I Built Fields
I have always enjoyed collecting sounds outside the studio. A place, an object, a short noise, or an interesting acoustic space can quickly become the start of a new idea.
I built Fields to make that process more immediate. My phone is always with me, and the iPhone microphones are surprisingly good for casual recordings. When I need more control, I can still connect an audio interface and use any microphone I want.
