Principles of Quality Audio

Quality Audio

Introduction

Audio is an important part of our lives. We listen to music, watch movies, and play games with audio. Good quality audio can make these experiences more enjoyable. In this article, we will discuss the principles of quality audio.

What is quality audio?

Quality audio is audio that is clear, natural, and engaging. It has a wide frequency range, good dynamic range, and low noise levels. Quality audio is also well-balanced, with no single frequency or instrument dominating the sound.

How to achieve quality audio

There are a number of factors that contribute to quality audio. These include:

The quality of the recording equipment.
The skill of the recording engineer.
The quality of the playback equipment.
The listening environment.

Recording equipment

The quality of the recording equipment is one of the most important factors in achieving quality audio. Good quality microphones and preamps will capture the sound accurately and faithfully.

Recording engineer

The skill of the recording engineer is also important. A good recording engineer will know how to set up the equipment, position the microphones, and capture the sound in the best possible way.

Playback equipment

The quality of the playback equipment is also important. Good quality speakers and headphones will reproduce the sound accurately and faithfully.

Listening environment

The listening environment can also affect the quality of the audio. A good listening environment is quiet and free from distractions. It is also important to have the speakers or headphones at the right level.

Conclusion

Quality audio is important for a number of reasons. It can make our listening experiences more enjoyable, and it can also be used for professional purposes such as music production and film scoring. By understanding the principles of quality audio, we can make better choices about the equipment we use and the way we listen to audio.

Recognize high quality audio files.

How can we distinguish real quality audio files from poor quality files?

It will have happened to everyone at least once to hear a song and to notice that it was “of low quality”, even if it was quite “difficult”! The size of an audio file is not always a sign of quality, but why? Before we understand it, a premise is needed that we put into practice to see if the files we have are really qualitative without trusting our ears too much.

Audio files

Maybe not everyone knows that every ‘file’ we have on our PC is nothing more than a list of bytes or bits that are no more than 0 and 1. To get a picture, imagine a 10MB file (MegaByte exactly), which can be a song, a fairly large picture, 10 seconds of HD video, it is about 80,000. 000 bits (1 byte = 8 bits and 1 bit = 0 or 1) or 80 million 0 and 1, almost the population Italian.

However, audio files that should simply contain “sound waves” are not always “pure”. That said, there are algorithms that can drastically reduce and compress the size of the audio file. However, it is obvious that there is more information about sound waves. The higher the definition of the audio, the larger the file that contains this information.

In view of this and depending on the “compression” we use, we have different files and qualities. There are algorithms that can store as much information as possible, and others that instead lose a lot of information and free up space. The former generally produce very large files and are also called “lossless” or “less lossless” precisely because they maintain the highest possible quality. 4 minutes of a song can also take 40 MB to 100 MB depending on the algorithm that compresses the files.

The best known and most commonly used are algorithms that allow you to store so much information, and others that instead lose a lot of information and gain space at the same time. The former generally generate very large files and are also referred to as “lossless” or “less lossy”. Precisely because they maintain the highest possible quality, 4 minutes of a song can also take between 40 MB and 100 MB depending on the algorithm that compresses it. The best known and most commonly used are

.wav / .wave WAVEform audio file format
.flac Free Lossless Audio Codec
.m4a Apple Lossless variant
.wma Windows Media Audio LossLess variant
The others, on the other hand, are perhaps the most common and allow you 4 minutes at around 10 MB if they are and are of high quality

.mp3 MPEG-1/2 Audio Layer III
.m4a Advanced Audio Coding Variant (AAC)
.wma Windows Media Audio variant

Which compression should I choose?

Now it is clear that we have to find a compression algorithm that allows us to maintain multiple frequencies. With a reduced size, our devices would be full immediately if each song occupied 30 MB!

After analyzing numerous songs with different extensions and looking around the internet a little, I came to the conclusion that the best encoding algorithm is undoubtedly the variable bit rate AAC compression with the .m4a extension, the best algorithm that you can use keep most frequencies higher in very small dimensions. Let us see together how the ghosts try to play the previous song in Apple Lossless (4 minutes and 23 seconds) first in MP3 with 320 kbps and fixed bit rate, then always with 320 kbps in variable bit rate (maximum quality) and finally in AAC to convert with variable bit rate (maximum quality), including the file size and the maximum frequency
