What is hi-fi? - Modification and Tuning Information

HERE YOU ARE

HiFi is an abbreviation of "High Fidelity", meaning high loyalty in English. In some technical aspects, music systems with a margin of error below certain ratios (i.e. in compliance with HiFi norms) and for home use are accepted as HiFi systems. However, HiFi norms are very low standards, and there is not much relationship between technical measurements and the sound quality perceived so far. As a result, two more concepts such as High End and Ultra-Fi have been developed to express a higher level of performance in recent years. However, there are no clear distinctions between them. In order to better understand what it means to express with high fidelity, it is useful to take a look at what kind of sound goes through musicians' performance to our perception:

1. The musicians hear and perform the music according to the acoustic characteristics of the studio or concert hall in which they are located. For example, in an environment with a short reverberation period, a musician hears a note for a shorter time and adjusts the tempo of the music accordingly. (Music of Sound, James Boyk)

2. According to the number, type and placement of the microphone, the sounds coming directly and reflected are detected by the microphones at different rates, at different time intervals.

3. The sound perceived by each microphone is converted into electrical energy and transmitted to a recorder and recorded by this device in a magnetic recording medium. In recent years, many systems (eg 44100 / second) have been taken and digital systems in which samples that are assumed to represent all have been recorded, rather than all of them being recorded as analog (analog). (When the first commercial samples of these systems were developed, it was claimed that no difference could be detected by the human ear between the original with a signal represented by 44100 samples per second. The companies that have developed these systems are working on systems that make 192 thousand samples per second today.)

4. Recorded sounds are processed through tone adjustment, reverberation effect addition, compression which are considered to be more than the harm of the benefit. The most important of these is compression. In most live music, the difference between the lowest and highest volume is greater than the capacity of current technologies. In addition, since it is not possible to listen to music as loud as the original in home conditions, compression is applied, which means that the difference between low sounds and loud sounds is reduced. If it is not practiced, the sound may either be so low that we cannot hear the low sounds or that the loud sounds disturb us, our neighbors.
we have to open as much as we can. There is a very important issue in the compression process, which is inevitable to apply. Compression should be done separately for each sound. If compression is made after the sounds recorded in separate environments are combined, a new sound emerging during the flow of the music will cause a frivolous attenuation in the ongoing sounds. (Compression In Mastering, Bob Katz)

5. Sounds processed in this way are combined in a stereo system so that the left and right channels are balanced. The purpose of stereo systems is explained by deceiving the human hearing system's ability to perceive the direction of the human hearing system by using only two audio channels, thus creating a scene image as if there are more than two sound sources. However, it is inevitable that a two-channel system to be produced at the same cost will be of lower quality than a single-channel system. As a result, even if we accept that obtaining a stage image can have a positive effect on the pleasure of music, it is quite doubtful that the sound quality will contribute more than the other aspects. In addition, with the sound coming from many places to our ear, the sound coming from two directions in a way that creates that feeling can definitely not have the same effect. For example, when we listen to a stereo system in which all the ringtones are recorded in a channel, we feel as if our ear on the other side is ticked. For this reason, priority is given to making the recordings more comfortable by making sacrifices from the realistic scene image. For example, as if the drum set is stretching from one end of the stage to the other, some ringtones are recorded to the right, some to the left and some to the middle. (Since the product to be put on the market will be used in various environments from portable music systems to very high quality systems, the procedures specified in articles 4 and 5 are taken into consideration in all these environments. Producer companies optimize their products according to different strategies according to their marketing strategies.)

6. Recorded recordings are converted to sound in our home HiFi system.

7. The sounds that are affected by the acoustic of the room in various ways reach our ears.

8. Our brains selectively perceive and interpret the features of the sound transmitted to him by the ear in line with our current mood, experience, expectations, and attention. For example, while we focus our attention on how detailed the sound is, we cannot evaluate other features. As you can see, the sound undergoes significant changes from the performance of the music to our ear. Registration, and possibly
The design works of HiFi system manufacturers are aimed at achieving the most comfortable and enjoyable results in practice, rather than keeping the sound faithful.

It was nice I would wonder if I would understand HİFİ music but now I know what exactly Turkish ...
