o
The ‘ Recording Schedule ’ section provides selection of continuous or periodic
recording. For continuous recording simply leave the ‘Periodic Recording’ option
unchecked.
o
Options available in the ‘ Audio Options’ will vary according to your device’s
capabilities. Options include the following:
▪
Channel Selection selects which channels to record on.
▪
Sample Rate should be set based on the frequency band of interest and
data rate considerations. A 96 kHz sampling rate is often a good choice for
general environmental noise measurements. Contact OI support if unsure.
▪
Preamp Gain should usually be set to ‘High’. This will result in a maximum
SPL before clipping of approximately 175 dB re 1 uPa. The ‘Low’ setting
should be used for very noisy environments such as in the vicinity of pile
driving. The low setting increases the maximum SPL to around 187 dB, but
comes at the cost of lower sensitivity.
▪
High pass filter . This should usually be turned off. This only used in
very high energy sites or when towing a SoundTrap behind a boat. Turning
this on reduces sensitivity in the band 0 to 600 Hz, while leaving higher
frequencies unaffected.
