WTH this catch(...) is???

    catch (CAXException &e) {
        NSLog(@"Error returned from setupAudioSession: %d: %s", (int)e.mError, e.mOperation);
    catch (...) {
        NSLog(@"Unknown error returned from setupAudioSession");

Found out it’s C++ feature, it’s kind of default case for catch clauses.

Working with audio this week. Just checked if I understand dB correctly.
