Monaural or monophonic sound reproduction is sound intended to be heard as if it were emanating from a position. Wikipedia The difference between monophonic (mono) and stereophonic (stereo) sound is the number of channels used to record and play audio. Mono signals are recorded and reproduced using a single audio channel, while stereo sounds are recorded and reproduced using two audio channels. As a listener, the most notable difference is that stereo sounds are capable of producing width perception, while mono sounds are not.
Mono audio means that only one signal is sent to all speakers. In this scenario, you may want to switch to mono audio to bring all of the audio layers to the foreground, regardless of which audio channel they play on. Mono sound recording is done primarily with a microphone and only one speaker is required to hear the sound. In the days of presidential talks by the fireplace, the news, singers or musical groups or oral entertainment, stereo wasn't necessary.
When a listener at a certain distance is sitting exactly in the center between the two speakers, the mono signal will appear to be exactly in the center of the plain between the two speakers. I'd be surprised if a sound card could only output mono audio, but a superficial Google reveals that people report this exact problem. Mono (monaural or monophonic sound reproduction) has audio on a single channel, often focusing on the “sound field”. It would be beneficial for those users if the games were released in mono so that they could also enjoy 3D sound with their non-stereo TV.
In today's era of technology, most signals are more compatible with stereo sound, rather than mono sound, which was widely used for radio transmissions in the past. 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). Sometimes, by experimentation or by accident, very interesting things happen in the field of stereo sound design, use them. In the 1960s, albums were released both on monaural LPs and on stereo discs because people still had their old mono players and the radio station was mostly AM.
The mono mode provides more power and clarity at lower frequencies; this can be useful if the track doesn't make the most of the stereo field and the bass frequencies compete with each other (if they exist on both channels). Therefore, you are more than likely to believe that the sound is coming from the center of the speakers, confirming the idea of a phantom mono sound source. Width (X-axis) is just one of the three dimensions you can perceive using a stereo system. Subsequently, frequency modulated (FM) radio was introduced, which offered better sound quality and the ability to transmit stereo music added during the transmission process (modulation).
However, in places that have several speakers, such as clubs, cafes or restaurants, the stereo system can cause phase cancellation problems and therefore make the mono the right choice.
