Sampling rate determines the sound frequency range (corresponding to pitch) which can be represented in digital waveform. The range of frequencies represented in a waveform is often called its bandwidth.

The number of samples taken per unit time, i.e., the rate at which signals are sampled for subsequent use, such as for modulation, coding, and quantization.

How fast a Digital Recorder or Player samples a Signal. CD and Mini Disc use a rate of 44.1kHz which is 44,100 samples per second.

The number of times an analogue waveform is measured or sampled per second to convert it to digital.

For digital audio, the number of times per second that a sound wave is measured. A higher sampling rate provides a more faithful reproduction of the sound.

Rate at which samples of a particular waveform amplitude are taken.

When audio is digitized, the sampling rate is the number of "pictures taken" in a second. A high sample rate means that the resolution of the recording is high, thus very "accurate". Most common sample rates in professional recording are 44.1Khz and 48Khz.

For a given measurement, the number of times that it is sampled per second in a time division multiplexed system. Typically, it is at least five times the highest data frequency of the measurement.

The rate at which the samples of a signal are taken in an A/D converter circuit or the rate they are generated by a D/A converter circuit. The unit of sampling rate is samples per second, often expressed as bytes/sec or even Hz.

In digitising operations, the frequency with which samples are taken and converted into digital form. The sampling frequency should be at least twice that of the analogue frequency being digitised. Thus, the sampling rate for hi-fi playback is 44.1kHz, slightly more than double the 20kHz frequency humans can hear.

The number of discrete (physical) samples of a continuous signal (such as sound or video) taken over a given period of time. The digitized result obtained matches the actual source of the sample when more samples are taken over the same period of time.[Go to Top of Page

Refers to the number of samples captured per second. While recording in Goldwave a variety of sampling rates can be selected. A selection of 44100 samples per second or 44.1 kilohertz is selected to give the best possible sound quality with a reasonable file size (exercise 2). The higher the sampling rate the higher the quality and size of the file.

How a movie or piece of music has been recorded or copied. The higher the sampling rate, the better the quality.

The rate at which a digital player or recorder samples, or reads, a digital data signal. CD, DCC and Minidisc have a sampling rate of 44.1 kHz representing 41,000 bits of digital Data is sampled every second. DAT tape uses rates of either 48 kHz or 44.1 kHz, while DAB radio will use 32 kHz. The DAC attached to each particular component will have a processing speed equal to or greater than the sample rate. The faster the sample rate, the more information can be processed every second. DVD has been developed with a sample rate of 96 kHz for increased data processing.

How fast a digital recorder or player samples a signal. CD, DCC and MiniDisc use a rate of 44.1kHz - ie 44,100 samples per second - while DATrecorders offer a choice of 48kHz or 44.1kHz, and Digital Audio Broadcasting will work on 32kHz. A digital-to-analogue converter needs to work on all three rates. The sampling rate determines the highest frequency recordable a digital system can carry - hence the development of higher-sampling formats, such as Pioneer's 96kHz system, for better treble extension.

The time interval which specifies how often amplitude measurements (samples) of a source are taken at in a digital recording. A digital recording will not accurately measure frequencies above half of the sampling rate. The higher the rate, the more real the sound sounds.

(telecommunication) the frequency of sampling per unit time

The rate at which a waveform audio driver performs audio-to-digital or digital-to-audio conversion. For compact disc - digital audio (CD-DA), the sampling rate is 44.1 kHz. See also compact disc - digital audio

Sampling rate defines the no of samples taken from a continuous signal

How many times a sample of sound is taken over a specific period of time.

Also called Sampling Frequency. The number of times per second that an analog sound is converted into digital data. A sampling rate of 44.1 kHz means that 44,100 digital conversions are being performed each second. If this number is higher, a broader frequency range of sound can be captured as data.

Also called a "sample rate". Typically expressed in samples per second, or hertz (Hz). The rate at which samples of an analog signal are taken and converted into digital form. A computer sound card will sample a received analog signal, (input for example through a microphone), and digitize it. A higher sampling rate provides a better quality reproduction than a lower sampling rate. The higher the sampling rate, the higher the frequency range of the recording.

A measurement of how precisely a digital file duplicates the analog audio it describes. The lower the number, the poorer the replica (and usu. the smaller the file).

number of samples taken per unit of time. In digital signal processing (Nyquist theory) it is necessary to sample twice as fast as the highest frequency component.

The frequency with which an analog-to-digital converter scans an incoming electrical signal. Higher sampling rates yield greater audio fidelity but require more storage capacity. The four most commonly used sampling rates are: 44.1 kHz (used in CDs); 48 kHz (used by professional DAT recorders); 32 kHz (used by consumer DAT recorders and for broadcast); and 22.05 kHz (used for broadcast and multimedia purposes). (See "Analog To Digital Converter," "CD," and "DAT")

The frequency at which a digitizer reports coordinate (or other) information. Sampling rate is not always directly related to the bandwidth.

The rate at which a sound is converted into numbers, in Hertz.

The frequency of sampling. The higher the sampling rate (that is, the more samples taken per unit of time), the more closely the digitized result resembles the original.

Sample rate is the rate at which a digital audio device samples the full analog sound wave. Digital audio is a representation of the full wave - it's takes a series of "snapshots" of the wave, and the more snapshots it takes, the more accurate it sounds. The higher the sampling rate, theoretically the more accurate it sounds. CD Audio and Minidisc are standardized at 44.1KHz, or 44,100 samples per second, while DAT can do 32, 44.1, and 48KHz. Super Audio CD, DVD-Audio, and High Resolution DAT can go up to 96KHz.

The number of times per second the data is sampled (hertz). See also, "Additional Audio Terms ".

Indicates the speed a digital recorder or player samples a signal.

In digital systems, the rate in Hz at which the circuitry determines the signal amplitude. For CDs, this is 44.1 kHz; for RDAT recorders, it can be either 48, 44.1, or 32 kHz.

The frequency with which samples of a physical variable, such as sound are taken. The higher the sampling rate, the more closely the digitized result resembles the original.

Frequency with which a digitizer takes measurements of the analog voice signal.

Also referred to as sampling frequency, this is the rate at which "snapshots" of an analog signal are converted into digital representations. The higher the sampling rate, the greater the accuracy of a digital reproduction. See Nyquist Theorem.

When an analog-to-digital converter digitizes an analog audio signal, it rapidly samples (or takes "snapshots" of) the analog signal's amplitude at regular intervals. These amplitude measurements are then converted to binary digital data — 1s and 0s — for storage on a CD, MD, or other digital audio medium. The sampling rate (or frequency) is the number of samples taken per second. The standard sampling rate for CD is 44.1kHz — that's 44.1 thousand snapshots per second

The rate at which an analog signal is sampled in order to be converted into digital. The higher the rate the more accurately the analog signal is duplicated in digital form.

the rate at which samples of a waveform are made. Must be twice the highest frequency one wishes to capture. Commercial compact discs use a rate of 44,100 samples per second.

In thresholding, the sampling rate is the interval at which metric samples are taken. The interval is specified in seconds.

When an analog-to-digital converter digitizes an analog audio signal, it rapidly samples (or takes "snapshots" of) the analog signal's amplitude at regular intervals. These amplitude measurements are then converted to binary digital data — 1s and 0s — for storage on a CD, MD, or other digital audio medium. The sampling rate, or "sampling frequency," is the number of samples taken in one second. The MiniDisc format uses the CD-standard sampling rate of 44.1kHz (44,100 samples per second), so it's a perfect match for recording from CDs.

The precision with which a digital file describes the analog sound it represents. Basically, a lower rate produces files that sound worse and take up less drive space than those with a higher rate. CDs have a sampling rate of 44.1 kHz, and DAT machines have a sampling rate of 48 kHz. MiniDisc player/recorders with a built-in sampling rate converter can handle both rates.

The range of instrument sampling, ranging from 5KHz, that determines the output quality. 5KHz would be in relation to music from a radio as 44KHz is to CD quality.

The number of samples obtained in a digitization process per unit of time or distance.

The frequency of sensor sampling by a datalogger. Typically once per second or once per minute for environmental variables like temperature, but can be much faster (in the millisecond, or thousandth of a second, range) for some sensors.

The rate in samples per second at which the audio data was recorded. The sampling rate ranges from 5500 (one fourth of the Mac sampling rate) to 48000 (Digital Audio Tape (DAT) sampling rate).

A term describing how frequently the detector generates a reading through checking the flow cell. The proper sampling rate is often a very sensitive setting, as too fast a rate can generate more data than necessary and too slow a rate may allow a narrow band to be missed.

The number of points of data, in pixels per inch, that are created by a scanner per linear distance. In this book, sampling rate means the optical sample rate changed by interpolation or subsampling. Also called ppi rate. See also optical sampling rate.

In musical applications, the rate at which a computer measures sound. External sound is fed to a music computer, e.g. the Fairlight, via an analog to digital converter. Within this device the sound wave is measured a fixed number of times per second. The frequency at which the sound is measured is called the sampling rate and the higher the rate, the more accurate the sample. For professional fidelity, the sampling rates chosen by the recording industry are between 40,000 and 50,000 times per second.

The number of samples taken per second. Typical sampling rates vary from 11kHz to 48kHz. See sampling, Nyquist frequency.
