Greetings Everyone, First, thanks to all who read or responded my previous posts--everyone's help and insight was appreciated. Second, as I continue my cochlear implant research, and creating virtual listening environments for 'real-world' testing of hearing-impaired listeners, I have made recordings of various places using my Core-Sound TetraMic. Now I have recordings using the TetraMic along with a TASCAM DR-680 and an Earthworks calibration mic (for analyzing levels and spectral content), but I've encountered a problem using the VVMic software. Len M. (of Core Sound) has been good to respond, but the problem is vexing. I've tried contacting David M. of VVMic fame, but no luck thus far getting a reply from him. The software works fine with A- (raw) or B-format files as long as I don't use the calibration files supplied with my TetraMic (these are the *.IIR files). I am hoping someone will look at the numbers below and compare them to their TetraMic cal files. I realize the files are unique to a given microphone, but if numbers are missing or far from what appears normal, this would suggest a problem with the cal files and not the software. Not all of the columns or rows are filled in, but that's the way they appear in VVMic for TetraMic. I could manually enter these numbers in the EQ settings, but I'm not sure whether that would fix the problem because the numbers may be outside of normal ranges. When using the cal files, the processing is quite slow, and the resulting wav files, when viewed in a basic DAW (time-amplitude window), show a wild, exponential-looking function that shoots off of the window. Note: The wave file doesn't appear like a clipped signal. Many thanks for any help here (or maybe somebody knows how to get in touch with David McGriffy?). Best regards, Eric Cal values shown below (and I hope the formatting stays intact when viewed in email):
