Description

The Earthworks M23 is a precision omnidirectional measurement microphone engineered to capture sound with minimal coloration, extending its frequency response up to 23 kHz. For anyone who needs trustworthy data rather than a flattering coloration, that extended high-frequency reach matters — it means the mic can pick up detail well beyond the range of typical vocal or instrument mics, making it a solid choice for acoustic measurement and analysis tasks.

Omnidirectional pickup pattern for consistent capture regardless of source position
Extended frequency response up to 23 kHz for detailed high-frequency accuracy
Designed for measurement and calibration applications where precision matters

Because it’s built around measurement accuracy rather than tonal character, the M23 is well suited to studio calibration, room analysis, loudspeaker testing, and other technical listening tasks where a flat, predictable response is the priority. If your setup depends on knowing exactly what’s happening acoustically in a space rather than shaping a particular sound, this microphone gives you a dependable reference to work from.

It fits naturally into any recording or acoustic workflow where verification is part of the process — checking room treatment, confirming speaker output, or documenting how a space actually behaves versus how it’s expected to behave. The M23 doesn’t try to make anything sound better; it simply tells you what’s there.
