Hi Dan,
Nice you mention this, I have recently been testing a couple of=
applications with my low noise omni mic, my opinion is the fabber applicat=
ion / Signal scope pro is the best all round and polished yet due to the la=
ck of compensation doesnt seem that accurate compared to holding it side by=
side with a real spl meter, I could be very wrong here also, but my experi=
ence comparing it to the Studio Six SPL Pro application next to my Type 2 m=
eter gave very similar measurements that were within .5 dB of each other.
Heres a blog entry on the subject of modifying a relatively cheap microphon=
e, the Giffen Smart Talk and adding a PIPMICS low noise omni capsule in its=
place.
http://www.urlme.net/blog/?p=3D1439
This enables measurement at least down to 20dBA. - Which is still unconfirm=
ed, I would like to find someone with an SPL meter thats reliable down to 2=
0 dBA and also owns a 2nd generation ipod touch or iphone with studio six d=
igitals SPL Pro meter so we can really confirm if the application is accura=
te enough compared to a SPL meter thats able to measure low levels. If thi=
s really does work as advertised its very valuable for the nature recording=
community considering the cost and bulk of carrying a larger SPL meter aro=
und. There also additional benefits such as SPL graphing over time as shown=
in my blog.
Kind Regards,
Mike.

Because of the noisy mic/preamp you can't measure low ambient SPLs.

it's a poor substitute for the real thing. That said, I use the GPS, camer=

SLR, a SLM, and a real GPS often for professional results.
