Polyphonic ringtones

The number of chords in a mobile phone is equal to the number of tracks in the midi format, but each track of a mobile phone is a single-tone track. This is the biggest difference from the midi we often listen to on a computer, and the number of chords affects the ringtone effect. The origin of the.

Chords are three or more simultaneous or sequential pronunciations that are combined according to a certain interval relationship and are called "chords." Traditional harmony consists of three degrees as the principle of chord formation. It is usually pronounced simultaneously. When you press 1, 3, 5 on the piano at the same time, it is a major three with 1 as the root. The advantage of chords is that they are full of sound and expressive. The junior sounds sound very loud, while the minor three chords are euphemistically sounding.

The so-called electronic music midi format records the timbre, the sound name, the loudness, the angle, the time, etc. of each sound, and queries the sound library according to the record to obtain the sound to be generated. In simple terms, each track corresponds to a musical instrument that records the musical sound played by the musical instrument at every moment in a specific format. For example, if a chord composed of the above-mentioned 135 is recorded on the track defined as a piano at a certain moment, then the chip obtains the corresponding sound effect by querying the sound bank, and then composes and plays the sound. So the sound bank is a key factor in determining whether midi sounds good, and a good sound bank is very much a place.

The method of recording music in a mobile phone is the same as or similar to midi. All recorded are monophonic, and complex chord sound effects are not recorded. That being the case, why are our mobile phones still so beautiful? Since you cannot press "135" on a piano at the same time, you can press 1, 3, and 5 on three pianos at the same time. In fact, cell phone chords are realized in this way. Such chords are not as good as real ones. The chords are nice, but it's almost confusing to release them from the phone. This process of turning a chord on one musical instrument into n musical instruments seems to be called "chord decomposition." If you often use psmplay to convert phone ringtones, then when the converted midi is more complicated, it will prompt "decomposed chords over 16..." Similarly, many songs that sound good on a computer are not resolved directly. When it comes to mobile phones, the effect is much worse. As long as you look at the midi editing software with a little better, you can find that there are often many tracks in the same tone, and each track is a single tone.

Therefore, a 16 "chord" mobile phone can achieve 5 kinds of musical instruments at the same time issued a triad, and 40 "chord" mobile phone can make 5 kinds of instruments issued seven chords at the same time, or 13 kinds of musical instruments issued a chord at the same time, or ... The more "chords" you have, the more combinations you can have and the richer the timbre. This is where the difference in sound effects brought by the number of mobile phone "chords" is.

At present, on the domestic market, mobile phones, ring tones can be roughly divided into monosyllabic ringtones, 3 chords, 4 chords, 16 chords, 32 chords, 40 chords, 64 chords and other ringtones. The difference between the mono and chord sounds is large; the 4 chord and 16 chord sounds are too booky and the difference is relatively large. The difference between the 40 and 32 chords is not great, and the 64 chords and the 40 chords are very different. Big. In short, 3 chords, 4 chords are a grade, 16 chords are a grade, 32 chords, 40 chords are a grade, and 64 chords are a grade.

For distinguishing chords, our average consumer is unable to hear because our ears are not professionally trained. If each of us can instantly hear how many chords and how many chords are in the song, then people People can be musicians. Chords only play a role in embellishment. It does not mean that the more the number of chords, the better the tune will be.
