154 results about "Effects unit" patented technology

An effects unit or effects pedal is an electronic or digital device that alters the sound of a musical instrument or other audio source. Common effects include distortion/overdrive, often used with electric guitar in electric blues and rock music; dynamic effects such as volume pedals and compressors, which affect loudness; filters such as wah-wah pedals and graphic equalizers, which modify frequency ranges; modulation effects, such as chorus, flangers and phasers; pitch effects such as pitch shifters; and time effects, such as reverb and delay, which create echoing sounds and emulate the sound of different spaces.

Integrated multi-format audio/video production system

A multi-format digital video production system enables a user to process an input video program to produce an output version of the program in a final format which may have a different frame rate, pixel dimensions, aspect ratio, or any combination thereof. An internal production format of 24 fps is preferably chosen to provide the greatest compatibility with existing and planned formats associated with HDTV standard 4:3 or widescreen 16:9 high-definition television, and film. Images are re-sized horizontally and vertically by pixel interpolation, thereby producing larger or smaller image dimensions so as to fill the particular needs of individual applications. Frame rates are adapted by inter-frame interpolation or by traditional schemes, including “3:2 pull-down” for 24-to-30 fps conversions. Simple speed-up (for 24-to-25 conversions) or slow-down (for 25-to-24 conversions) for playback, or by manipulating the frame rate itself using a program storage facility with asynchronous reading and writing capabilities. The step of converting the signal to a HDTV format is preferably performed using a higher sampling clock frequency and a resizing to HDTV format frame dimensions in pixels. An integrated system having digital television standard conversion capabilities is disclosed, wherein audio/video input signals are received in high-speed serialized form, transferred to a high-speed data bus, and fed to one or more standards converters operating according to the invention, thereby providing a variety of serial or parallel digital signal outputs. The system may further include a wide-/local-area network interface, mass storage, digital effects unit and workstations for multiple users.

Wireless karaoke microphone headset

The invention discloses a wireless karaoke microphone headset which comprises a left microphone, a right microphone, an ADC (analog-to-digital converter), a reverberation effect unit, a sound mixing unit, a DAC (Digital To Analog Converter), a left loudspeaker, a right loudspeaker and a wireless connection unit which are positioned at auricular positions when a user wears the headset. Voice signals picked up by the left and right microphones enter the reverberation effect unit after being subjected to analog-to-digital conversion by the ADC; after carrying out reverberation effect processing on the digital voice signals, the reverberation effect unit sends the digital voice signals to the sound mixing unit; the wireless connection unit receives a music accompaniment signal sent by a mobile terminal and sends the music accompaniment signal to the sound mixing unit; the sound mixing unit mixes the voice signals with the music accompaniment signal and sends a mixed signal to the DAC; after digital-to-analog conversion, sound is output to the user by the left and right loudspeakers; and the headset can send the sound mixed signal, the voice signals or a holographic sound field signal to the mobile terminal in a Bluetooth manner. By the wireless karaoke microphone headset disclosed by the invention, karaoke experience of the user and sharing capacity of high-quality sound an be effectively promoted.

Magneto-resistive effect device of the cpp structure and magnetic disk system

The invention provides a magneto-resistive effect device of the CPP (current perpendicular to plane) structure, comprising a magneto-resistive effect unit, and an upper shield layer and a lower shield layer located with that magneto-resistive effect unit sandwiched between them, with a sense current applied in a stacking direction, wherein the magneto-resistive effect unit comprises a nonmagnetic metal intermediate layer, and a first ferromagnetic layer and a second ferromagnetic layer stacked and formed with that nonmagnetic metal intermediate layer sandwiched between them, wherein the first ferromagnetic layer and said second ferromagnetic layer are exchange coupled via the nonmagnetic metal intermediate layer such that where there is no bias magnetic field applied as yet, their magnetizations are anti-parallel with each other, and at least one of the upper shield layer and the lower shield layer has an inclined magnetization structure with its magnetization inclining with respect to a track width direction, so that by the magnetization of that inclined magnetization structure, a bias magnetic field can be applied to the first ferromagnetic layer and the second ferromagnetic layer. It is thus possible to obtain a magneto-resistive effect device of improved reliability that enables a structure capable of having a narrowed read gap (the gap between the upper shield and the lower shield) to be adopted to meet the recently demanded ultra-high recording density, allows a stable bias magnetic field to be applied in simple structure, and obtain a stable magneto-resistive effect change.
