3D audio at your fingertips.
Capture three-dimensional sound fields with remarkable spatial fidelity. The BACCH-BM allows you to record sound exactly as you hear it. Ready to use with any two-channel recorder or microphone preamp capable of supplying +48 V phantom power, it's perfect for field recording, studio recording, and virtual reality content creation.
designed for in-ear use.
The BACCH-BM was designed with the human ear in mind. Unlike many other binaural microphones, BACCH-BM capsules are small enough to fit in your ear canal, allowing them to effectively capture the spectral cues of your pinnae and produce true binaural recordings that are spatially accurate. Easily changeable ear plugs ensure a snug and comfortable fit for ears of all shapes and sizes.
best-in-class performance.
The BACCH-BM has the highest signal-to-noise ratio and sensitivity of any microphone its size.
individually calibrated and equalized.
Each microphone is individually calibrated and equalized to generate a flat frequency response (+/- 1 dB) from 20 Hz to 30 kHz. Every BACCH-BM ships with custom equalization filters and calibration files.
