摘要:
A three-dimensional sound reproducing apparatus is configured by cascading a sound field effect adding unit and a crosstalk canceling unit. The sound field effect adding unit adds a predetermined three-dimensional sound field effect to an input audio signal, thereby generating audio signals respectively corresponding to left and right channels. The crosstalk canceling unit performs a calculation process on the audio signals of the two channels so that, when the audio signals are respectively generated by two loudspeakers positioned in front of a listener, the audio signals reach the left and right ears of the listener without producing crosstalk. The resulting audio signals are supplied to the loudspeakers, respectively. A sound image localizing unit receives two-channel audio signals which are obtained by encoding a center-channel audio signal, a left-channel audio signal, a right-channel audio signal, and a nonlocalization audio signal, and outputs two-channel audio signals in which sound images are to be respectively localized at virtual loudspeakers.

A CPU of an effector calculates envelopes of an impulse response waveform from sample data of impulse response waveform data supplied from a microphone via an A/D converter circuit. Next, CPU detects a section during which a slope of the detected envelopes takes a value near “0” during a predetermined time or longer. CPU calculates an average value of sample data during the detected section to correct a DC offset. Thereafter, CPU acquires a maximum value of absolute values among the sample data during the detected section, and determines this maximum value as a background noise component value. The background noise components are removed from each sample data constituting the impulse response waveform data.

A photosensitive resin composition for use in manufacture of multi-layer circuit boards with connecting holes between layers is disclosed. The resin composition has excellent adhesion with a plating metal, resolution, photo-curing, thermosetting, thermal resistance, and is capable of being developed using an alkaline solution or an aqueous solution containing a non-halogen based organic solvent as the developing solution. The resin composition comprises a photosensitive epoxy resin, a thermosetting epoxy resin, a reactant of a carboxylic acid added to an acrylonitrile-butadiene rubber and an epoxy resin, a photo-polymerization initiator and a thermosetting agent. This reactant facilitates a high density pattern of connecting holes for circuit boards of the layered type.
