Before you start recording you can select the appropriate record mode by setting three record parameters:
You can record in mono or stereo (provided that your sound hardware has that capability).
You can choose from three standard sampling rates (11.025 kHz, 22.050 kHz and 44.100 kHz) which are provided by most sound cards currently available. You can also set any nonstandard rate supported by your audio card.
Remember that even if the lower sampling rate (11.025 kHz) is acceptable for recording speech signals, it is inappropriate for most music recordings. On the other hand, the upper rate (44.100 kHz), providing the CD-quality sound reproduction, is usually too high for the purpose of restoration of old recordings as fast sampling tends to re-emphasize the noise. For this reason the default value of the sampling rate was set to 22.050 kHz.
NOTICE
DART XP Pro offers you an extremely fast, high-quality resampling utility (available after choosing the Resample command from the Toolbox menu). You may, therefore, consider recording and restoring an audio signal at a lower rate and then upsampling it (there are several advantages of doing this - see Resample ).
You can choose whether individual samples are stored in a single byte (8 bits) or an entire word (16 bits) of computer memory. In order to guarantee good quality of the reproduced sound you should always use the 16-bit resolution.
NOTICE
The system will not allow you to change the above settings once the process of recording is started. If you are recording new material in an existing soundfile, all settings have to remain unchanged.
