+<b>DISABLE_ASYNC_SAVEFRAME</b><br />
+save() and saveFrame() will not use separate threads for saving and will block until the image is written to the drive. This was the default behavior in 3.0b7 and before. To enable, call hint(ENABLE_ASYNC_SAVEFRAME).

 		This representation of sound, as a discrete &#8220;frame&#8221; of frequencies and amplitudes independent of time, is more akin to the way in which we perceive our sonic environment than the raw pressure wave of the time domain. Jean-Baptiste-Joseph Fourier, a nineteenth-century French mathematician, developed the equations that allow us to translate a sound pressure wave (no matter how complex) into its constituent frequencies and amplitudes. This <em>Fourier transform</em> is an important tool in working with sound in the computer.

 		Our auditory system takes these streams of frequency and amplitude information from our two ears and uses them to construct an auditory &#8220;scene,&#8221; akin to the visual scene derived from the light reaching our retinas.6 Our brain analyzes the acoustic information based on a number of parameters such as onset time, stereo correlation, harmonic ratio, and complexity to parse out a number of acoustic sources that are then placed in a three-dimensional image representing what we hear. Many of the parameters that psychoacousticians believe we use to comprehend our sonic environment are similar to the grouping principles defined in Gestalt psychology.
