Musical Demon's Impulse vs Fields

Impulse is a focused, musician‑built tool for capturing clean, accurate impulse responses from your own cabinets, rooms, and signal chains. Designed for engineers, guitarists, producers, and sound designers, it delivers a streamlined workflow with precise alignment, intelligent safety checks, and fast export. With real‑time environmental analysis, automatic trimming, and a robust deconvolution engine, Impulse helps you capture reliable IRs anywhere — from studios to rehearsal spaces. Whether you’re building a personal IR library or refining your live rig, Impulse gives you the clarity and control you need.

Fields is a portable field recording app for capturing, organizing, and editing sounds in one place. Record sounds wherever you are, organize them with photos, notes, and locations, and edit your recordings directly in the app. Capture new material with the built in microphone or an external audio interface, import existing audio files, and keep everything organized in one place. Fields includes useful editing tools such as cut, copy, crop, reverse, fades, gain, normalize, filter, pitch, speed, trim silence, and noise reduction. A pre roll buffer helps you save sounds that happened just before you pressed Record, while automatic location tagging and the built in map make it easy to remember where each recording was captured. Your recordings belong to you. Fields requires no account, uses no tracking, and lets you choose between iCloud and Local Storage.
