The audio files, in 48 kHz WAV format with up to 24 bit resolution, can be transferred to the FX100 via the front or rear USB ports. These stored audio files are then available for selection in the FX-Control software. The playback time is determined either by the duration of the measurement, or can be arbitrarily long; when the end of the audio file is reached, it starts again from the beginning.
FX100 users can download the latest version V2.9.0 of the FX-Control software on the NTi Audio Service & Support page. Using this FX-Control software, the firmware of the FX100 can be updated.
