When it comes to sound quality, stereo is undoubtedly the superior choice over mono. It offers a fuller, more detailed listening experience due to the fact that more audio is recorded than in mono format and is presented in a more natural way. Unless some other form of sound recording surpasses it, stereo is here to stay. For the average listener, stereo sounds broader, more detailed and more realistic.
However, in places with multiple speakers, such as clubs, cafes or restaurants, stereo systems can cause phase cancellation problems and make mono the better option. Mono audio tends to sound flat, tight and less dynamic because all audio elements are grouped together on the same channel and played at the same volume. It usually sounds as if it's coming from a single point on a 2D plane, usually the front or center. You can then spread them out across the stereo field or image by moving the audio to the left, right and center.
When recording with lots of acoustic elements, such as a live music performance or reverberating instruments like a violin or guitar, stereo is the way to go. If you're using a stereo playback system, make sure your head is in an equilateral triangle with the speakers. Mono signals are recorded and reproduced using one audio channel while stereo sounds are recorded and reproduced using two audio channels. If the voice sounds too bright, adjust the tone to a negative amount to keep it out of the high range.
I downloaded it a couple of months ago and use it every time I convert mono recordings to stereo. If you've ever observed the waveform of a stereo audio file on a digital audio workstation (DAW), you'll notice two waveforms apart from the file. Depending on the combination between the left speaker and right speaker, you can adjust the perceived location of the sound source anywhere between them. The stereo microphone technique used is called X-Y technique; it produces a moderately wide stereo image that's also compatible with mono.
We can use the stereo field to make room for all mix elements and make it sound wide and prominent. When processing a stereo recording, you'll need to move one microphone recording to the left and one to the right. If a sound originates directly in front of you, it will travel an equal length to your left and right ears. Stereo audio files like MP3s and WAVs contain information about left and right channels that tell left and right speakers when to pressurize and extract air.
But when recording multiple items, I'd recommend recording in stereo to get different volumes between items on different channels. At the time records were produced, two separate mixes were made - one for mono and one for stereo. Mono is better if the original recording was in mono; artificially created stereo albums are like post-production 3D movies.
