Vermont Folklife Center
Vermont () is a state in the New England region of the Northeastern United States. It borders Massachusetts to the south, New Hampshire to the east, New York to the west, and the Canadian province of Quebec to the north. According to the most recent U.S. Census estimates, the state has an estimated population of 648,493, making it the second-least populated of all U.S. states. It is the nation's sixth smallest state in area. The state's capital of Montpelier is the least populous U.S. state capital. No other U.S. state has a most populous city with fewer residents than Burlington. Native Americans have inhabited the area for about 12,000 years. The competitive tribes of the Algonquian-speaking Abenaki and Iroquoian-speaking Mohawk were active in the area at the time of European encounter. During the 17th century, French colonists claimed the territory as part of New France. Conflict arose when the Kingdom of Great Britain began to settle colonies to the south along t ...

Electret Microphone
An electret microphone is a microphone whose diaphragm forms a capacitor (historically-termed a ''condenser'') that incorporates an electret. The electret's permanent electric dipole provides a constant charge on the capacitor. Sound waves move the diaphragm, changing the capacitance , which produces a corresponding voltage change across the capacitor of . The electret's constant charge eliminates the need for the polarizing power supply required for non-electret condenser microphones, though a preamplifier is typically incorporated to boost the audio voltage signal. Electret material An ''electret'' is a stable dielectric material with a permanently-embedded electric dipole that persists for hundreds of years due to its high resistance and chemical stability. The name comes from ''electr''ostatic and magn''et''; drawing analogy to the formation of a magnet by alignment of magnetic domains in a piece of iron. Electrets are commonly made by first melting a suitable die ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microphone Practice
There are a number of well-developed microphone techniques used for recording musical, film, or voice sources or picking up sounds as part of sound reinforcement systems. The choice of technique depends on a number of factors, including: * The wish to capture or avoid the collection of extraneous noise. This can be a concern, especially in amplified performances, where audio feedback can be a significant problem. Alternatively, it can be a desired outcome, in situations where ambient noise is useful such as capturing hall reverberation and audience reactions in a live recording. * Degree of directionality of pickup: in some settings, such as a home video of a birthday party, the person may wish to pick up all the sounds in the room, making an omnidirectional mic desirable. However, if a TV news crew is filming a reporter at a noisy protest, they may only wish to pick up her voice, making a cardioid mic more desirable. * Choice of a signal type: Monaural, Mono, stereo or multi-chann ...

Computer Software
Software consists of computer programs that instruct the Execution (computing), execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or Interpreter (computing), interpreter to execution (computing), execute on the architecture's hardware. Over time, software has become complex, owing to developments in Computer network, networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applicat ...

Multi-track Recording
Multitrack recording (MTR), also known as multitracking, is a method of sound recording developed in 1955 that allows for the separate recording of multiple sound sources or of sound sources recorded at different times to create a cohesive whole. Multitracking became possible in the mid-1950s when the idea of simultaneously recording different audio channels to separate discrete ''tracks'' on the same reel-to-reel tape was developed. A ''track'' was simply a different channel recorded to its own discrete area on the tape whereby their relative sequence of recorded events would be preserved, and playback would be simultaneous or synchronized. A multitrack recorder allows one or more sound sources to different tracks to be simultaneously recorded, which may subsequently be processed and mixed separately. Take, for example, a band with vocals, guitars, a keyboard, bass, and drums that are to be recorded. The singer's microphone, the output of the guitars and keys, and each indivi ...

XLR Connector
The XLR connector (also Cannon plug and Cannon connector) is a type of electrical connector primarily used in professional audio, video, and stage lighting equipment. XLR connectors are cylindrical, with three to seven connector pins, and are often employed for analog balanced audio interconnections, AES3 digital audio, portable intercom, DMX512 lighting control, and for low-voltage power supply. XLR connectors are part of the international standard for dimensions, International Electrotechnical Commission, IEC 61076-2-103. The XLR connector resembles the DIN connector, but is larger, more robust and physically incompatible. The generic term "XLR" began as a trademark of Cannon (company), Cannon Electric, with the letters standing for X model connector with an added "L"atch feature, and "R"esilient neoprene rubber surrounding the female contacts. History and manufacturers The XLR connector was invented by James H. Cannon#James H. Cannon, James H. Cannon, founder of the Cannon ...

Zoom H4 Handy Recorder
The H4 Handy Recorder is a handheld digital audio recorder from Zoom, featuring built-in condenser microphones in an X-Y stereo pattern, priced from around US$280 depending upon memory capacity . Recordings are stored on an SD card (128 MB supplied), or via a USB cable to a computer running digital audio workstation software (Cubase LE supplied). Applications and recording formats The H4 can record in stereo or four-track mode. In stereo mode WAV or compressed (MP3) files may be made.

With device firmware from version 2.0, SDHC cards up to 32 GB in size are supported, storing 16 hours at the highest-quality setting (uncompressed PCM WAV, 24 bit, 96 kHz, stereo). Basic four-track recordings can be made in the field with the built-in microphones and two additional input ports which accept external signal sources via XLR or 1/4-inch connectors. Stereo mode In stereo mode, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flash Memory
Flash memory is an Integrated circuit, electronic Non-volatile memory, non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR gate, NOR and NAND gate, NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level, depending on whether the state of the bit line or word lines is pulled high or low; in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented by Fujio Masuoka at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than the entire devi ...

AA Battery
The AA battery (or double-A battery) is a standard size single cell cylindrical Dry cell, dry battery. ANSI and IEC battery nomenclature gives several designations for cells in this size, depending on cell features and chemistry. The Battery nomenclature, IEC 60086 system calls the size R6, and American National Standards Institute, ANSI C18 calls it 15.Classic (LR6) datasheet from energizer.com It is named UM-3 by Japanese Industrial Standards, JIS of Japan.
