This depends on the usage of the word. Usually, it refers to either one of two things. 1) taking a short segment of a sound or song such as a single drum beat or a short piano riff and saving it as a new audio file. This is usually used in "mashups" and sound collages or as triggers in live performances. 2) the frequency at which data is taken to describe a sound wave. You can think of this as plotting X and Y coordinates on a graph to describe a sound wave which a computer can translate into speaker movement and finally sound. The higher the sample rate, the higher quality the audio.
What else can I help you with?
Which one is called non probability sampling a. cluster sampling b.quota sampling c. systematic sampling d. stratified sampling?
Answer is Quota sampling. Its one of the method of non-probability sampling.
Define the four different sampling techniques?
1) Simple random sampling 2) Systematic sampling 3) Stratified sampling 4) Cluster sampling 5) Probability proportional to size sampling 6) Matched random sampling 7) Quota sampling 8) Convenience sampling 9) Line-intercept sampling 10) Panel sampling
What is the difference between quota sampling and cluster sampling?
What is the difference between quota sampling and cluster sampling
What is the difference between Sampling error vs sampling bias?
Sampling error leads to random error. Sampling bias leads to systematic error.
What is the difference between flat top sampling and natural sampling?
in flat top sampling the electronic circuit required for sampling are less complicated as compared to the one used in natural sampling, at demodulation of the sample it is very difficult to maintain the natural waveform of the natural sampling so flat top sampling can easily be demodulated.
Why is the CD-audio sampling rate 44.1kHz not 40.0 kHz?
This site explains it: http://www.cs.columbia.edu/~hgs/audio/44.1.html
What is sampling rate in audio digitization?
Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.
What is the relation between sampling rate and bit depth?
Sampling rate and bit depth are two key parameters in digital audio that affect sound quality. The sampling rate refers to how many times per second an audio signal is sampled, determining the frequency range that can be accurately captured. Bit depth, on the other hand, defines the number of bits used to represent each sample, influencing the dynamic range and detail of the audio. Higher sampling rates and bit depths generally lead to better audio fidelity, but they also result in larger file sizes.
The audio CDs you buy at your favorite music store are recorded at a sampling rate?
44.1 kHz
Why was the PCM sampling time set at 125 microseconds?
The PCM (Pulse Code Modulation) sampling time of 125 microseconds corresponds to a sampling rate of 8 kHz, which is sufficient to capture audio frequencies up to about 3.4 kHz, adhering to the Nyquist theorem. This sampling rate ensures that the essential details of the audio signal are preserved while minimizing data size. Additionally, 125 microseconds is a practical choice for efficient processing and storage in digital communication systems.
Why PCM sampling time at 125 m sec?
PCM (Pulse Code Modulation) sampling time of 125 microseconds is typically associated with a sampling rate of 8,000 samples per second. This rate is sufficient for capturing audio signals within the frequency range of human hearing, which is generally up to 20 kHz, in accordance with the Nyquist theorem. By sampling at this rate, the system effectively captures the necessary signal details while minimizing aliasing and ensuring good audio quality.
Sampling?
The act of taking a pre-recorded piece of audio and using it in a new and different musical composition in various ways.
What is the sampling rate of Blu-ray DVD?
The sampling rate of Blu-ray discs is typically 48 kHz for audio, which is standard for high-definition video and audio formats. Blu-ray can support various audio formats, including Dolby TrueHD and DTS-HD Master Audio, which provide lossless audio quality. Additionally, Blu-ray video has a resolution of up to 1920x1080 pixels, with frame rates often at 24, 30, or 60 frames per second, depending on the content.
Is lightning audio any good?
Lightning audio (I presume an MP3, WAV or FLAC), is very good if the audio sampling is high enough quality and the audio output (being Speakers or Headphones) are high enough quality, it could sound like lightning just struck beside you.
Why is sampling used when recording sound?
Sampling is used when recording sound to convert continuous audio signals into a digital format that can be processed, stored, and manipulated by computers. It captures discrete values of the audio waveform at specific intervals, allowing for accurate reproduction of sound while reducing the amount of data needed for storage. This process enables various applications, such as music production, sound design, and digital communication, making audio flexible and accessible. Additionally, sampling rates determine the quality and fidelity of the recorded sound, impacting the overall listening experience.
How can the file size of an audio clip be calculated?
If you know the bits per second of the audio clip, then simply multiply that by the length of the audio clip. If you do not know the bits per second, and the file is uncompressed, then you will have to take the sampling frequency (generally 44.1KHz), multiply it by the size of each sample, multiply by the number of channels and then finally multiply by the length of the audio clip. For example, a 1 second wav file with the default attributes of a 44.1KHz sampling frequency, 16 bit samples and 2 audio channels (stereo) will be 44100 * 16 * 2 * 1 = ~1.4 megabits = ~176 KB = ~172 KiB
How does sampling rate relate to the size of mp3 files?
The sampling rate affects the audio quality.For instance,a song sampled at 192 kilobits per second is three times the size of a song sampled at 64 kilobits per second and will be of better sound quality.
