Audio channels, which have a great influence on video/audio files, are a vital concept. However, a few people know this concept well, which makes people unable to choose an appropriate audio channel according to their needs. To solve this problem, this article will elaborate on the details about audio channels in the next paragraphs.

Audio Channels

In this section, readers will understand the definition of audio channels. At the same time, there are different types of audio channels that will be mentioned, which will also help people have a better understanding of audio channels. Now, let’s move to the definition of audio channels!

The Definition of Audio Channels

An audio channel refers to a communication route or passage that enables a sound signal to be spread from the player source to the speaker. It should be noted that you can find one, two or more channels in a single video/audio file. In addition, the number of audio channels also means a lot.

The number of audio channels represents the number of independent audio signals when a sound is being recorded or played, which is closely concerned with the number of sound sources, the number of speakers, and people’s auditory experience. For instance, as the number of audio channels increases, people’s auditory experience will gradually improve.

Moreover, because the number of channels is different, there are different types of audio channels, which will be discussed in the next section. Let’s have a look!

Different Types of Audio Channels

In this section, 4 types of audio channels, including mono channels, stereo channels, 4.0 surround sound and 5.1 surround sound. Now, let’s go to the wonderful audio channel world!

Mono Channels

A mono channel means that the sound is played through one speaker or picked up by only a microphone. In mono audio equipment, people can only feel the position of the sound before and after. However, people can’t feel the lateral movement of the sound such as the sound moving from left to right.

Since the sound from a mono channel has no sense of direction, people have a commonplace auditory experience. However, a mono channel also has advantages. For example, because the sound from a mono channel is more focused and direct, this audio channel is widely used for fields such as stage sound, restaurant background music and corridor radio. 

Stereo Channels

A stereo channel means that the sound is recorded or played by two separate audio channels (left and right), which aims to simulate the direction and dimensionality of sound in a natural environment. Specifically, with the difference between the left and right channels, a stereo channel allows listeners to perceive the direction and position of the sound, providing people with a more three-dimensional auditory experience.

Compared with mono channels, stereo channels are more expressive since they can restore the sense of space and hierarchy of the sound source more accurately. Supported by these advantages, stereo channels are widely used for fields like music, movies and games. For instance, in terms of movies and games, stereo channels can simulate more realistic sound, enhancing the experience of viewers and players.

4.0 surround sound

4.0 surround sound refers to a sound processing technique that uses four separate audio channels to create surround sound effects. With this technique, listeners can feel sounds coming from the front, back, left and right.

Generally speaking, a 4.0 surround sound system is usually comprised of four speakers and a subwoofer. Simply put, the left and right front speakers play the front audio signal. The left and right rear speakers play the rear audio signal. At the same time, the subwoofer plays the low-frequency signal.

Now, 4.0 surround sound has become increasingly popular. You can see a 4.0 surround sound system on numerous occasions like home theater systems, movie theaters, music production and games. For example, in music production, 4.0 surround sound technology can be used to produce more rich and immersive musical compositions.

5.1 surround sound

5.1 surround sound can be defined as an audio system that utilizes six separate audio channels to create surround sound effects, providing people with a richer and more authentic auditory experience. Compared with 4.0 surround sound, 5.1 surround sound is more advanced.

5.1 Surround sound works by dividing the audio signals into six separate channels. These audio signals are then transmitted to five full-range speakers and a subwoofer for playback. To be exact, the five full-range speakers are responsible for playing front left, front right, front center, back left and back right audio signals, while the subwoofer is responsible for playing low-frequency signals.
