Introduction
This article demonstrates how to generate a quasi-infinite number of sounds using math formulas. Also, a sample program is provided to allow you to do experimentation by your own. have great times!Background
A sound is basically a sine wave traveling in the air. it is characterized by a power and a frequency. the power determines the sound loudness and the frequency determines its pitch. if you are not familiar with this phenomenon, I

An Feishi is a typical case of associated positioning. It builds its own positioning based on market leaders. "An Feishi is only the second in the car rental industry. Why are we still looking for us? Because we work harder. An Feishi has been losing money for 13 years, but he has been making a profit since he admitted that he has ranked second. The reason w

Description
A delta wave is a high amplitude brain wave in humans with a frequency of 1-4 hertz which can be recorded with an electroencephalogram (EEG) and is usually associated with slow-wave sleep (SWS ).
-From Wikipedia
The researchers have discovered a new kind of species called ''otaku ", whose brain waves are rather strange. the delta wave of an Otaku's brain can be approximated by a Polygonal Line in the 2D coordinate system. the lin

Nchannels
Number of channels in the waveform-audio data. Monaural data uses one channel and stereo data uses two channels.
Nsamplespersec
Sample rate, in samples per second (hertz). IfWformattagIs wave_format_pcm, then common valuesNsamplespersecAre 8.0 kHz, 11.025 kHz, 22.05 kHz, and 44.1 kHz. For non-PCM formats, this member must be computed according to the manufacturer's specification of the format tag.

Movement of the hand or foot will cause the receiving device to detect a change in Doppler frequency shift. These frequency changes are very small, usually only a few hertz, compared to the bandwi

We live in an age surrounded by numbers. Information changes rapidly, open the computer can see a lot of news, not only the country and other countries. These rely on the internet to spread so quickly, and the Internet relies on computers to show people. The world's first computer Eniac was born in 1964 at the University of Pennsylvania in the United States, its volume is very high, power consumption, can store less data, the CPU can not do very advanced calculation. However, the development of

Some graphics systems are designed toTo use a variable refresh rate. For example, select a high refresh rate for the stereoscopic display app to display two views of the scene alternatelywill not blink. This type of application typically uses multiple frame caching methods. Sometimes, the refresh rate is described in how many cycles per second or

load condition and the distance and response time of the user.BandwidthBandwidth (band width), also known as frequency, is the amount of data that can be transmitted at a fixed time, that is, the ability to transmit data in a transport pipeline. In digital devices, the bandwidth is usually expressed in bps, which is the number of bits per second that can be transmitted. In analog devices, the bandwidth is typically expressed in cycles per second or hertz
