The term audio itself refers to sound technology. Sound occupies an important place in a person’s life. If at first it was just a way of perceiving the environment, now with its help people even learned to have fun.
What would be our life without music? They say that it can even heal. Working with audio is very difficult and is characterized by many nuances. It is no coincidence that there are many common myths about sound, its processing and recording, which simply require consideration.
Investing in high-quality sound can not begin with the correct acoustic design of the room.
This statement is actually wrong. It must be understood that the concept of “sound quality” is actually nonlinear. It is also important to remember that the room in which the recording is being conducted is an equally important part of the overall contribution, and the source of the sound itself. That is why it is so important to pay special attention to the room. In some of them there are truly euphonic places where standing waves are neutral or even serve as an adornment of their source. But without a thoughtful and even scrupulous approach to this issue, it may happen that even the best equipment and instruments in the world will sound disgusting.
It’s better to pay attention to a good preamplifier than a good microphone.
This question has no unambiguous answer. Initially, it is the microphone that affects the sound more than the preamplification. But, as mentioned above, quality is a non-linear concept. As a result, it happens that inexpensive dynamic microphones can respond better to certain sources, rather than elite condensers. In this case, the narrow bottle neck will be the preamplifier. It is he who will determine the quality, influencing the nature of the sound and its tone. Experienced sound engineers say that the best combination will be an excellent microphone and a decent preamplifier. But even the quality of the microphone does not prevent the situation if the preamplifier turns out to be bad. So in reality you have to experiment, choosing the best option.
It’s best to record vocals in booths or small rooms.
This statement has very little to do with reality. Even if acoustics are linearized by absorbers, small rooms are usually still unsuitable for recording vocals. In such rooms, resonances are located in the middle range of frequencies, where, exactly, the vocal is located. As a result, the voice can acquire unnecessary coloring. With reduction, it will be very difficult, if not impossible, to fix it.
If there is a desire to record vocals so that it is free from natural reverberations, then the best place for this will be a medium-sized room.
There should be appropriate acoustic design, sound absorbers and maybe even diffusers. Another option would be a small room with non-parallel walls and fiberglass insulation. If you record audio in a medium-sized room, then the vocals will sound accordingly. If the record is produced in a tight closed space, then nothing good will come of it.
Those sounds that the human ears can not hear can be sensed in a certain way.
On this issue it is difficult to unequivocally state anything, because there are not enough studies that would determine the effect of ultra-low and superhigh frequencies on a person. This case is quite subjective, having more to do with science than with psychophysics and emotional moments. For example, some people can not perceive even half of the range heard by others. Others go beyond the generally accepted framework, while others generally hear sounds from otherworldly worlds.
When mixing tracks, you should try to immediately have a CD quality.
The information is actually another task – to create a balanced and integral sound that meets the stated artistic task.Brightness, sound and other characteristics of commercial audio CDs should be given away already for mastering.
Thanks to mastering, the song starts to sound like on the radio.
This statement is an absolute lie. Mastering, indeed, is an important process. But the musical quality of the composition is laid down even at the time of composition, arrangement and performance. Sound quality is generated when recording a track. It is worth noting that the well-written material will be fairly easy to mix. It will be necessary literally from the skin to get out to make it sound bad. If the mixing is done correctly, then the quality material recorded will become a real masterpiece. Of course, not everyone has the opportunity to record in the highest quality studios. But even in a limited budget and with the appropriate literate approach, you can achieve acceptable audio quality. But if you treat the process without due attention and wait for the appearance of quality from just mastering, then nothing good will come of it. In the best case, a mastering engineer will have to spend his time, even if only to make something out of the spoiled melodies that would at least be less disgusting to listen to.
Sound can be improved by high quality cables.
And although it is difficult to be absolutely sure of the fallacy of this opinion, most likely, so it is. Only here it is difficult to make a correct comparison, because our perception is tied to the person himself and depends on many different factors. Even if you listen to the sound and immediately reproduce it through the same system, you will hear a difference. The perception of sound relates not only to physics, but also to psychology. Differences in the conductivity of the cables do not play a special role. The difference can be seen only if you work with very long cables. And if earlier work was conducted with Chinese material from the nearest flea market, then switching to a normal cable can significantly change the sound.
The best sound quality is obtained when recording at a level of about 0 dBFS.
This statement is an absolute myth. When digital audio was just beginning, the recording was conducted with a bit capacity of 16 bits. Now it is already 24 bits, which allows you to leave a lot of pure headram and not to think about the efficiency of using bits. And many preamps work best with levels that are significantly less than 0 dBFS. That is, a quality-looking level of -1 dBFS after passing through the preamplifier will be distorted. This will worsen the overall sound quality. It is important to remember that the analog part of the converter will work better in a certain range of maximum levels, usually from -10 to -20 dBFS.
You can completely remove the vocal from the finished track.
In fact, this is not true. People come up with the most unusual ways to remove certain sounds from the received audio material. But none of them is able to do it completely. By subtracting phrases, EQ or M / S processing, you can only crush the vocals. And it will turn out, I must say, not bad. Only now the vocal is a very broadband source. The most advanced method today is spectral editing. The sound is presented in the form of a multi-colored picture, which can be edited in any graphic editor, in the same “Photoshop”. Then it remains to convert the picture back to sound. Skillful processing allows you to achieve really amazing results. Even for the game “Guitar Hero” the songs were decomposed into composites using this technique. But she also has her limitations, especially they are critical to vocals.
For the best recording, you need the best equipment.
And this opinion is wrong. You need the right equipment, and the right ear.So do not invest in expensive items, it is better to spend money on acquiring new knowledge, on training with real professionals, on developing your own skills and hearing.
