The frequency of the sample units.
When digitally sampling a signal, the rate at which level measurements of the signal are taken.
In analog to digital signal processing, the sample rate is the interval at which samples of an analog signal are taken. The sample rate for digital telephony, for example, is 8000 per second.
The number of times per second a digital audio signal is sampled - defined in kilohertz (kHz).
Sample Rate Conversion/Converter Sandbox
The number of samples per second at which a sound is processed (usually ranges from 8 kHz to 192 kHz NOTE: CD quality is 44.1kHz, or 44,100 samples per second.
The rate at which measurements are made. The measurement sample rate is primarily of interest when considering the effect of time skew (i.e., how close in time are a series of measurements). The fastest sample rates are when measurements are made that are initiated by a single instruction with multiple repetitions.
The number of times per second an analogue current (carrying a sound signal) is sampled in the process of digitisation. Along with the resolution (q.v.) of samples this determines the accuracy or fidelity of digital sound.
A piece of music is "measured" while it is imported into your computer. Each sample, or measurement value, becomes a digital number and is saved. The sample rate is then a statement, in Hertz, of how often the incoming music signal is measured. As a general rule, the higher the sample rate, the higher the sound quality. Wave files (.wav), for instance, have a sample rate of 44.1 Kilohertz (KHz).
refers to the frequency an analog audio stream is "sampled" or converted into digital. The higher the sampling rate means the closer the digital file will be to the original analog source and the better the quality. CD-quality requires a sample rate of 44,100 khz.
a rate, not a set of complex values
number of times data are collected in a given period of time (i.e. a 30-second sample rate means that data are collected every 30 seconds).
The number of conversions per second the DAC is producing.
The amount of audio samples every second in an audio stream. CDs are sampled 44100 times a seond. (More)
A sample is simply a snapshot of a sound at a given point in time. The sampling rate is a measurement of how many snapshots are taken. The best example is a movie camera that takes 24 still photographs per second. When they are played back at a certain speed in the cinema, the result is almost like a real life. Each frame of film is a sample; 24 frames per second is a sampling rate. If you reduce the number of frames per second, the film would look like a sequence of still images.
describes how frequently an analog audio signal is sampled as it is converted into a series of numbers. 44.1 kHz is the standard sample rate for compact disks; 48 kHz is often used with digital audio tape (DAT) recording; 22.050 kHz is frequently used for games and multimedia. A higher sample rate allows a higher frequency response. In order to accurately reconstruct a sound, the sample rate must be at least twice the highest frequency in the sound.
The frequency at which an analog audio stream is "sampled" or converted into digital. The higher the sampling rate, the closer the digital file will be to the original analog source and the better the quality. A sample rate of 44,100 khz is considered CD-quality.
The rate at which a signal or value is sampled. It is frequently expressed as samples/sec (S/s), kilosamples/sec (kS/s), or megasamples/sec (MS/s).
the rate of sampling in samples, kilosamples, or megasamples per second
The inverse of the time between successive samples of an analog signal.
number of samples per second used for audio. A higher sample rate yields higher quality audio that is larger than that of lower sample rates. Common multimedia sample rates include 11.025 kHz, 22.050 kHz, and 44.100 kHz.
In digital modulation, the rate at which a particular signal is sampled and digitized
The accuracy with which sound is recorded. Generally, audio sample size is 8 or 16-bits. The latter is more accurate and provides more dynamic range, but takes up more storage space.
A digital representation of an analogue signal created by checking, or sampling, the analogue voltage a fixed number of times per second. The greater the number of samples, the more accurate the representation of the analogue signal. The CD uses a sampling rate of 44.1kHz; it checks the analogue signal 44,100 times per second.
In digital recording, the number of times per second that samples are taken.
frequency - or number of times per seconds - at which a source signal is sampled digitally. Measured in Hertz, or cycles per second.
The number of samples of a sound per second.
The number of samples per second of audio taken measured in kilohertz. The higher the sample rate, the better the sound is represented at higher frequencies but, the larger the file will be.
What is sample rate and how does it effect audio quality? Read On
Similar to the frame rate for a film, this represents the number of times, per second, that the audio signal is captured. In general, the higher the sample rate, the higher the sound quality of the resulting audio, but the larger the audio file. The sample rate is very important in determining the highest frequency that can be captured. The human ear can hear frequencies from 20 Hz to a maximum of 20,000 Hz. For a frequency to be captured in an audio file, the sample rate must be more than twice that frequency. For instance, the sample rate of CD audio is 44,100 Hz (44.1 kHz) so that the highest frequency it can represent is 22,050 Hz. This clearly covers the range of human hearing.
The amount of times per second that an analog sound is captured by a digital recording. The preferred sample rate for DV and FCP is 48KHz.
When a computer is converting a song or video into a file, the number of times per second it takes a digital snapshot of the song or clip is called the sample rate. A song file with a 48KHz sample rate means that the computer “listened” to the original audio 48,000 times per second. 44.1KHz and 48KHz are high enough to reproduce all the sounds you can hear.
The speed at which audio samples are recorded and played back. This is analogous to video and film frame rates. Higher sample rates give higher audio quality at the expense of larger audio file size. Lower sample rates save disk space but result in poorer audio quality. Typically, 8 kHz is fine for human voice recording. Audio CDs are recorded at 44.1 kHz, and audio DATs are recorded at 32, 44.1, or 48 kHz.
The resolution of digital audio that determines it's sound quality. When audio is digitally recorded (digitized), it must be converted into a series of Sample s which can be stored in memory or on disk. The sample rate defines how many samples are recorded per second of audio input and is measured in Hz (Hertz, cycles per second) and kHz (Kilohertz, thousand cycles per second). Click the examples below to hear the difference between a few commonly used sample rates. Sample Rate Example 11025Hz 22050Hz 44100Hz (CD sound quality)
The number of times a digital sample is taken, measured in samples per second, or Hertz. The more often samples are taken, the better a digital signal can represent the original analog signal. Sampling theory states that the sampling frequency must be more than twice the signal frequency in order to reproduce the signal without aliasing. DVD PCM audio allows sampling rates of 48 and 96 kHz.
Sampling is the key technique used to digitize analog information. It is used to capture continuous phenomena, whereby periodic measurements are taken. If the sampling rate is at a high enough quality, the human sensory organs cannot discern the gaps between or data omitted from each measurement. With audio data, the sample rate refers to the Kilohertz (Khz) measurement at which the data was sampled. The lower the sample rate, the more data has been discarded from the original source.
Refers to how frequently a digital oscilloscope takes a sample of the signal, specified in samples per second (S/s).
The number of times a digital sample is taken (samples per second, or Hertz). A higher rate means better reproduction of the original signal; a sampling rate must be double the original signal frequency in order to avoid aliasing.
The number of samples taken of a particular signal in a given amount of time (usually one second). For CD this is 44.1kHz or once every 0.023msec. DVD supports both 48kHz and 96kHz.
The numeber of times per second audio recording software takes the digital audio signal given from the input. Higher sample rate equals to larger files but higher quality.
