SIGNAL/RTS APPLICATION NOTES

Transferring from SIGNAL to DAT
Following is a connection diagram for transferring sound material from SIGNAL to the DAT
recorder. Sample rates are shown in ()'s.

The sounds of interest are stored from SIGNAL buffers as Wave files. Then, running under
Windows, digital data flows from the Wave file on the computer disk to the DIO board,
under control of transfer software such as Windows Sound Recorder or equivalent, to the
S/PDIF input on the DAT recorder. Note that the RTS cannot currently write Wave files;
however a file converter could be written to convert SIGNAL files from the RTS into Wave
files.
Following are suggested operating steps:
1. Create a SIGNAL buffer containing the signal of interest and write it to a Wave file on
disk using "W /W" in SIGNAL.
2. Start Windows and launch Sound Recorder. Make sure that Sound Recorder can find the
DIO board and if necessary, set the Windows multimedia control panel to play through the
DIO board. Queue up the desired Wave file for playback.
3. Connect the DIO board output to the S/PDIF input on the DAT recorder.
4. Start recording on the DAT, then start playback in Sound Recorder. Stop the DAT
recorder after the sound completes.
The SIGNAL source buffer must either be created in the native sample rate of the DAT
recorder (44.1 or 48 KHz), or else written to disk and then converted to this sample rate (see
"Sample Rate Converter" above). Note again that SIGNAL buffer capacity is limited to
about 1.2 million data points, or about 27 seconds at 44.1 KHz sample rate.
