Hi,=0D

It has been quite a while since my last post. I've been mainly using an ag=
ed Atherstone parabolic dish with Twin Em172's and an LS-10 to record bird =
calls and insect sounds.=0D

Recently I've become more interested in natural soundscape recording and d=
ecided to treat myself to a Sony PCM D100, mainly because I also plan to lo=
ok into ultrasonic recording of insects (I'm a keen amateur entomologist) a=
nd the 192khz spec. would expand the upper frequency range. =0D

Apart from its somewhat 'Star Trek' styling, I am slowly getting used to t=
he Sony - I'm currently using an SASS-style rig with 2x2 EM172's shamelessl=

The PCM D100 manual mentions a S/N 100db feature using which - "Noise can =
be suppressed even with a low recording level" (full quote below).=0D

"With two A/D converters for one channel, the linear PCM recorder always =
reserves audio signals that are 12 dB lower than audio processed in the no=
rmal circuit in addition to the normal audio signals. If an over-input occ=
urs, recorded data from the point at which the over-input starts is replac=
ed and compensated. Replacement is executed while maintaining the linearit=
y of two A/D converters of different levels, realizing a high S/N ratio. N=
oise can be suppressed even with a low recording level. ON: S/N 100dB fun=
ction is enabled. OFF*: S/N 100dB function is disabled."=0D

Is this function likely to be useful in reducing intrinsic noise with quie=
t ambient recording or is there (as I suspect) a trade off in other ways?=

Although I am quite well versed in photography, I am still trying to come =
to terms with the technicalities of sound recording so any help with deciph=
ering Sony-talk would be most welcome.=0D
