Excellent book suggestion, boten...I've always been of the opinion that a studio should have a decent library of text reference materials (including magazine subscriptions to publications such as EQ, Recording, Keyboard, Guitar Player, ProSound News, Mix, etc.,)...
I should have mentioned a few other sites that offer helpful tools like "Delay Calculators" (much easier than in the old days when we used stopwatches

)...A quick and easy online version can be found
HERE. You can also download a freebie from
AnalogX.
Another useful tool from AnalogX is
Frequency Converter. Simply type in a note (such as A4) and the corresponding primary frequency will be displayed.
Also, remember that internet searches can reveal a plethora of useful information.
HERE is one site that links to many magazine articles that cover a wide range of information pertinent to recording (DAW and otherwise)...
The internet, in and of itself, is a valuable tool...Use it often to research & learn and your recording experience will be much more enjoyable (and productive)...

Papa
