The difference between mono and stereo is the number of channels they send to the speakers. Mono tracks send only one channel for all speakers. However, stereo tracks send two different channels, one for each speaker. Most people today use stereo because it sounds wider, more detailed and much more realistic.
What is the difference between mono and dual mono? Mono is a single track. When mixing, a mono track can be rotated forcefully to the right or to the left and anywhere in between. The dual mono format consists of two individual tracks that are usually shown on the left and right. Usually, they would have a shared sound source (for example, battery overhead) and could be placed on a stereo track inside a DAW.
The stereo will affect both the left and right channels equally. Add 3 dB of gain to 1000? that will be done on both channels. If you want to affect only one channel of the signal, use dual mono. This will most likely make it possible to switch between affecting the left channel and the right channel.
In general, mono or stereo audio is not categorically better than the other. Both types of audio serve a purpose. And both have features that can benefit your listening experience and your recordings if you know how and when to use them. In short, stereo amplifiers mix left and right signals to a certain extent due to shared components and the effect of interference.
You can then distribute them throughout the stereo field or the stereo image by moving the audio to the left, right, and center. In this respect, stereo is not just two sources of sound: it deduces a solid wall of sound with depth and breadth. It has its origin in the Greek word “stereos”, which means “solid, firm and three-dimensional”. In stereo amplifiers that share a common base (-ve), a power supply (power supply), a preamplifier and even some components of the circuit, the left and right channels are altered or, more precisely, are affected by “circuit exchange”.
That said, if you use monaural or single-earbud headphones, have a hearing impairment in one ear, or perhaps you tend to share your headphones a lot, it's best to use mono audio. In addition, Compressor in Dual Mono has independent processing for the left and right channels, so if the L and R signals vary significantly, the stereo image may fluctuate off-center. For more information, see the Wikipedia entry on “Wall of Sound” or “Spector Sound”. It's very interesting how the first pioneers thought about the transition from mono to stereo productions.
This refers to mono audio that has only one audio signal that uses a single audio channel for playback or recording. Try to find a good setting in stereo mode and then switch to Dual Mono to hear the difference (or lack of one). This is done by recording the main elements of a track, such as the main instruments and the vocals, in mono and the other supporting elements in stereo. Other effects processes also use stereo and dual mono, but compression is probably the best example and the easiest to understand.
Now that the concepts of stereo and dual mono are clear, let's discuss the relevance of mixing in a home studio. Stereo audio usually sounds fuller and more dynamic because it's not limited to a single audio channel. One way to find out is to open the audio file in a program like Audacity to check if the file has two waveforms (stereo) or just one (mono).
