TetraProc converts the A-format signals from a tetrahedral Ambisonic microphone into B-format signals ready for recording. Main features:
- A-B conversion using a classic scalar matrix and minimum phase filters, or
- A-B conversion using a 4 by 4 convolution matrix using measured or computed impulse responses, or a combination of both.
- Individual microphone calibration facilities.
- 24 dB/oct higpass filters.
- Metering, monitoring and test facilities.
- Virtual stereo mic for stereo monitoring or recording.
- Unlimited number of stored configurations.
- Jack client with graphical user interface.
TetraCal is the microphone calibration application for TetraProc. Given a number of impulse response measurements of a tetrahedral microphone (captured using Aliki) it computes the matching configuration file for TetraProc. Main features:
- Automatic determination of gain and directivity errors of the A-format microphones.
- Automatic computation of an A-B matrix compensating for those errors.
- Frequency and phase response display of all A and B format signals.
- Interactive adjustment of pre- and post matrix equalisers.
