An audio processor (10) that is specifically designed to be included in combination with an audio recording system or a movie theater sound system. The processor (10) consists of two major circuits, a single-ended, limited compressor/expander circuit (12) and an output circuit (205) that incorporates a dynamic noise reduction (DNR) circuit (206). A single adjustment sets the trip points for both the low-level and high-level operating mode of the compressor/expander circuit (12). Likewise, a sing...

An audio decoder which can reduce a memory circuit capacity necessary for performing a series of decoding processes and can perform a down mixing. The audio decoder decodes audio data of a plurality of channels encoded in a frequency domain by using a time base to frequency base conversion. After a down mixing process was performed to the audio data of the frequency domain by frequency domain down mixing circuit, it is converted into audio data of a time domain by frequency base to time base con...

An audio mixer has separate dry mix, effects returns mix and main mix mixing buses, each mixing bus having a separate mix output. Multiple audio signals are mixed together without effects processing onto a dry mixing bus. Simultaneously, the original audio signals are also mixed together at various levels onto multiple sends mixing buses which are coupled to an effects sends (or output). The mixed audio signals on each of the sends mixing buses are sent to either internal or external effects pro...

An audio label comprising a circuit board substrate with a sound-generating microchip and a photovoltaic cell both attached to the substrate such that the microchip is electrically connected to the photovoltaic cell so that power is provided to the sound-generating microchip. A sound reproduction unit is also attached to the substrate and is connected to the sound-generating microchip communicates signals to the sound reproduction unit which are then converted by the sound reproduction unit to a...

In one aspect, audio summaries and transition audio segments are sequentially rendered with at least one transition audio segment rendered between each pair of sequential audio summaries. Each audio summary comprises digital content summarizing at least a portion of a respective associated audio piece. In another aspect, an original audio file is annotated by embedding therein information enabling rendering of at least one audio summary contained in the annotated audio file and comprising digita...

A device (MS) having an electrical display (DSPL) is equipped with a transparent electrostatic diaphragm (ACT) vibrateably attached in front of the display. The display has been made electrically conductive and used as a stator of thus formed electrostatic speaker (TD1). A fluctuating DC-voltage is conducted to the diaphragm and display in order to resonate the diaphragm and produce sound respective to the fluctuation. The transparency of the diaphragm allows a user to see the display through th...

An audio system includes a circuit (12) for processing an audio signal, the circuit (12) having an input (20) for receiving the audio signal and an output (26) for supplying an output signal. The circuit (12) further includes a harmonics generator (22) coupled to the input (20) for generating harmonics of the audio signal and an adding circuit (24) coupled to the input (20) as well as to the harmonics generator (22) for supplying a sum of the audio signal and the generated harmonics to the outpu...

An improved audio cable comprising at least one pair of first and second insulated conductors located on opposite sides of a shielding member that extends the entire length of the cable. The first and second conductors are located on opposite sides of the shielding member. Bores, also called lenses, are formed on the shielding member that allow exposure of the magnetic fields of the first and second conductors to reduce inductance. In the first embodiment, the shielding member is a flat structur...

A method of encoding a multi-channel audio signal including at least a first signal component (LF), a second signal component (LR) and a third signal component (RF). The method comprises the steps of encoding the first and second signal components by a first parametric encoder (202) resulting in a first encoded signal (L) and a first set of encoding parameters (P2); encoding the first encoded signal and a further signal (R) by a second parametric encoder (201), resulting in a second encoded sign...

A circuit, which is enabling the superpositioning of different audio signals such as voice, music or ringer signals in a audio output device is achieved. The individual superpositioning can be activated and performed by a combination of resistors and switches without the need of an additional mixing amplifier as in prior art. One common output stage is used for all the signals activated and superpositioned. The adjustment of the amplitude of the output signal, which can be used for the volume ad...
