- Rycote's Microphone Data
One of the best free resources on the net, giving up-to-date
specifications on almost all current mics. What's particularly good is
that they've standardised their specifications format, which
makes it much easier to compare
- Sound On Sound's Technical
A lot of people don't seem to realise that this is on SOS's
site -- they don't make a big deal of it. However, there's masses of
useful info here, especially if you're just starting out.
- Rane's Pro Audio
Another slightly more specialist glossary which complements
the SOS one quite well.
