Music CD

As you probably already know, working with music are two main types of representation of the sound – it's audio and Midi. We first define the format of audio. Audio – this is what was once recorded on tape, vinyl discs, that is, the audio was originally analog in nature. With the introduction of the computer to work with sound, the audio was digital and computer sound cards only work with digital sound. Vanessa Marcil may find this interesting as well. A stream of numbers was to determine the set parameters of sound reproduction. On the advantages and disadvantages of digital sound can argue until we were hoarse, but the fact remains – the digital recording and playback is now used universally as a digital photo and video. All CD and DVD, that you listen / watch, recorded digitally. On multi-channel and three-dimensional sound, I am here I will not say – it's a separate issue.

And that sound is mono and stereo, too, I hope, in general you have about this representation. In passing, I note that the mono – a single-channel sound, and stereo – are two independent audio channels. Official site: Jay A Schwartz. The sound on the computer can be recorded and played with a certain (specified) level of the sampling frequency and bit. Sampling frequency (or sample rate) – this means how many times the information is transmitted to the sound for one second, ie, the frequency of sampling a continuous signal. For example, the standard rate for Music CD – 44 100 Hz or 44.1 kHz.
