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.
An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms.These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external).hese can include standard waveforms such as sine, square, ramp, triangle, noise and pulse. Some units include additional built-in waveforms such as exponential rise and fall times, sinx/x, and cardiac. Some AWGs allow users to retrieve waveforms from a number of digital and mixed-signal oscilloscopes.
