The 1974 range included one folk-style guitar (W-200) and eight dreadnoughts of increasing quality and decoration: W-240-12, W-250, W-260, W-280, W-300, W-300-12, W-500, W-600. Under Rudy Schlacher, most Washburn models were ordered in runs of 200 units, rather than ongoing production; if sales went well, further runs might be ordered.
The encoded tones provide information to automatic duplication machines, such as format, duration and volume levels in order to replicate the original video as closely as possible. DTMF tones are used in some caller ID systems to transfer the caller ID information, a function that is performed in the United States by Bell 202 modulated ...
The most common set of supported tones is a set of 39 tones including all tones with Motorola PL codes, except for the tones 8Z, 9Z, and 0Z (zero-Z). [6] The lowest series has adjacent tones that are roughly in the harmonic ratio of 2 0.05 to 1 (≈1.035265), while the other two series have adjacent tones roughly in the ratio of 10 0.015 to 1 ...
Roland GS, or just GS, sometimes expanded as General Standard [1] [2] or General Sound, [1] is a MIDI specification. It requires that all GS-compatible equipment must meet a certain set of features and it documents interpretations of some MIDI commands and bytes sequences, thus defining instrument tones, controllers for sound effects, etc.
Voltage vs. time of sine waves at reference and line levels, with V RMS, V PK, and V PP marked for the +4dBu line level. A line level describes a line's nominal signal level as a ratio, expressed in decibels, against a standard reference voltage. The nominal level and the reference voltage against which it is expressed depend on the line level ...
In telecommunication, a standard test tone is a pure tone with a standardized level generally used for level alignment of single links and of links in tandem. [1]For standardized test signal levels and frequencies, see MIL-STD-188-100 for United States Department of Defense (DOD) use, and the Code of Federal Regulations Title 47, part 68 for other Government agencies.
A tone in a contour-tone language which remains at approximately an even pitch is called a level tone. Tones which are too short to exhibit much of a contour, typically because of a final plosive consonant, may be called checked, abrupt, clipped, or stopped tones. It has been theorized that the relative timing of a contour tone is not distinctive.
An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. [1] The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness contours. By definition, two sine waves of differing ...
