Dayton Audio EMM-6
A precision electret condenser measurement microphone with a calibration file for accurate acoustic analysis
Overview
The Dayton Audio EMM-6 is an electret measurement microphone made for acoustic measurements in audio engineering and research. Dayton Audio markets it as a low-cost way to measure the frequency response of speakers and rooms. It is commonly used with room acoustic analyzers and measurement software like Room EQ Wizard (REW). A downloadable calibration file comes with it to correct the response to flat. It has been used in academic research and professional audio work, including at the Generative Art Conference (GA2019).

Design
The EMM-6 is a precision electret condenser microphone with an omnidirectional polar pattern. It is built for measurement and critical recording, where you need an extremely flat frequency response. The unit includes a calibration curve to correct deviations in its response across its operating range.
Context
The EMM-6 belongs to a family of Dayton Audio measurement microphones, alongside the UMM-6 USB and iMM-6 calibrated models. It is a low-cost alternative to higher-end measurement mics, with laboratory-grade accuracy at a fraction of the price. Academic and professional sources have referenced it as a reliable tool for acoustic analysis.
Market
The EMM-6 originally sold for $77.99 and is noted as a budget-friendly option for precise acoustic measurements. Current listings show it at around $66.74. It is still available and still used by both hobbyists and professionals.
