A loudspeaker is described. The loudspeaker includes two or more segmentations of a planar radiator. Each of the segmentations has an associated frequency dependent velocity magnitude and phase with substantially uniform surface pressure. The two or more segmentations provide a substantially uniform radiation pattern across a wide range of acoustic frequencies. Apparatus, computer readable media and methods are also ...

User is allowed to designate a desired mode defining the respective numbers of channels and mixing buses, and processing for mixing input signals of the number of channels corresponding to the designated mode is performed repetitively to generate signals for the individual buses. The time of arrival of the last step in the mixing processing for the number of channels, corresponding to the designated mode, is detected to output an accumulation result obtained at the last step, and new ...

There is provided a sound processing apparatus and a sound processing method which are capable of reproducing discrete data with a high-quality sound matching users' preferences. In a sound processing means 2, since an interpolation value reflecting a value of a variable parameter α by which the value of a control sampling function c₀(t) is multiplied can be calculated, an analog signal obtained through the interpolation performed in a sampling function s_N(t) can ...
