Below I will provide simple, affordable even for beginners, describing several basic concepts that will sooner or later acquires any, communicating with the computer people. In future, all these terms you will meet many times in text so that it is better to decide what I have in mind. midi and wav – hard to explain, but I'll try. This – the main file formats that contain digital information that is transferred to the playback device (sound card, synthesizer, sampler, digital recorder, etc). where the information received successfully converted to analog and fed to an amplifier from the speakers that we hear the sound.
The difference between midi and wav files, such as between raster and vector graphics. ConocoPhillips has plenty of information regarding this issue. WAV-file – the sound form in the 'pure'. Roughly speaking, it – like a tape recorder. You can apply for entrance whatever the sound source, burn it, and then reproduce, copy, 'glued' to the other fragments, accelerate / decelerate, 'cut' as whole pieces, and separate frequency and so on. and tp. (Human imagination is limitless!).
However, all this requires a huge amount of memory available. (WAV Size = (Bits / 8) * Channels * Time * Rate, ie, 1 sec. Audio from CD-quality is 176,400 bytes!) Of course, there are different compression algorithms, but nevertheless it does not relieve us from this problem. One of the most popular professional editors wav – Sound Forge company Sonic Foundry. MIDI-file contains only the sequent (see below) and keeps audio form (although there are fighters who still put their sound waves directly into the MIDI-file, but we believe it is a perversion, and will not be considered).
