Aragonite and calcite are polymorphs of calcium carbonate. It is harder than calcite (3.5 to 4, rather than 3, on the Mohs scale) and somewhat denser, but like calcite it responds to weak acid by vigorous bubbling.

Wavetable Synthesis Definition - Wavetable synthesis is a method for generating sounds from signals of a digital nature. The technique stores digital sound samples from various sources, which can later be modified, enhanced or combined for reproducing sounds. Wavetable synthesis is considered one of the oldest methods for generating sounds from computers. It differs from simple PCM sample playback because wavetable synthesis relies on looping over the buffer instead of simply a read once method.
Table-lookup synthesis (or Wavetable-lookup synthesis) (Roads 1996) is a class of sound synthesis methods using the waveform tables by table-lookup, called table-lookup oscillator technique. The length of waveforms or samples may be varied by each sound synthesis method, from a single-cycle up to several minutes.
