TetraMic

Common name: Core Sound TetraMic

Production Status: In production

The TetraMic is a tetrahedral microphone array for soundfield recording. It has applications with ambisonic recording. Each and every TetraMic is individually calibrated and comes with its own calibration files.  The output is A format but is supplied with VVMic software to enable conversion to B format and also to a wide variety of stereo and surround playback configurations. The four capsules are closely matched 12 mm cardioid electret types. The microphone output is unbalanced at its multipole connector and uses a single PPC4 transmitter, one etherCON cable and a single PPAc receiver that outputs four XLR-M balanced signals. Re-calibration intervalis 3 years for general usage and 2 years for precision acoustic measurements. The VVEncode operates with any recording application that can use four-channel VST or AAX plugins (e.g., Pro Tools, SONAR, AudioMulch, Plogue Bidule, Wavelab, Cakewalk, Cubase, Samplitude, Ableton Live, Nuendo, Reason, FL Studio, Sound Forge, Nuendo, Reaper). There is also a TetraProc application for Linux users developed by Fons Adriaenson.
