Update: Jim Dalrymple over at The Loop reached out to Apple for comment. Here's what they said:
"Apple buys smaller technology companies from time to time, and we generally do not discuss our purpose or plans."
As Dalrymple notes, this is typically the response Apple gives when they have indeed purchased a company.
Original Story: It looks like Apple acquired digital audio instrument and plug-in maker Camel Audio, according to the company's corporate information listed in the UK government's Companies House website.
