Stacks Image 133
High Resolution, Multi-channel Recording: Record up to 16 channels simultaneously (up to 8 channels on iPhone), including input, output, or virtual output channels, to 24-bit AIF, CAF, or WAV audio files. Record with sample rates as high as 768 kHz (supporting hardware required).

Continual Recording: The maximum single file length is 2 hours, 59 minutes and 59.9 seconds, but the Data Recorder can be configured to automatically begin streaming to a new file once the current user-defined file length has been reached. In this way, input data can be continually streamed to disk for many hours (as long as enough free disk space is available).

Record Calibration Information: The Data Recorder will automatically store calibration information, such as units and sensitivity, for each channel in a custom data chunk embedded in the audio file. The same metadata can also be exported to a separate CSV, MAT, or TXT file. Compatible software, such as SignalScope's File Player tool, can read this metadata along with the raw audio data and apply it for calibrated measurements and analysis of the raw data stored in the audio file.
