File name format
The first character of wav-file name matches the output selector switch position.
So the audio files names are e.g. “1anyName.wav” or “8anyName.wav”, whereby
“anyName” may describe the content of the wav-file for example “1_STIPA.wav”.
The maximum length of the filename is 8 digits, e.g. “xxxxxxxx.wav”.
Calibration data
The CF-Card keeps additionally the individual calibration data of the
NTi Audio TalkBox. The file is named “xxx.cal”. The CF-Card is labeled with the serial
number of the corresponding TalkBox, so the CF-Card and the NTi Audio TalkBox do
have the same serial number, guaranteeing accurate and calibrated operation.
The serial number on the CF-Card must match with the serial num-
ber of the NTi Audio TalkBox, otherwise the acoustical parameters of
the TalkBox are out of specifications.
