Mono vs. Stereo and When to Use Them

Mono vs. Stereo and When to Use Them

Playback systems typically use one of two speaker types. It can be monophonic (mono) or stereophonic (stereo).

The first option provides a single channel for music distribution. That means the same waveforms get sent to all of the speakers in the audio setup.

If you have a stereo-based system, you have two channels. They’re designated “left” and “right,” distributing different information to make the audio feel more realistic or lifelike.

The best time to use stereo for audio recording or playback is when you want to create an impression of sound source localization. It’s a technique that makes it seem like you can locate the exact place where you detected the noise.

When you create music or enjoy listening to different audio productions, several benefits of both styles might make one better than the other for your needs. That’s why it is crucial to review the advantages of both types.

Mono vs. Stereo and When to Use Them

The difference between monophonic and stereophonic sound involves the number of changes used for playing or recording audio. Mono signals use a single channel, while stereo uses two for these activities. That process allows stereo to offer width perception that mono does not provide.

Monophonic sound has all of the audio signals mixed into a single track. They’re routed together into one audio channel for playback, ensuring that you hear the complete mix simultaneously.

If you’re wearing headphones while listening to a mono track, you’d hear the same sounds in the left ear as you would the right.

This trait allows sound systems to have multiple speakers spread throughout the room to create a surrounding effect. Since the signal doesn’t contain level info or arrival time data, you don’t need to worry about replicating or simulating directional cues.

That’s why some of today’s most popular choices for mono sound include single-channel clusters, split clusters, and distributed speaker systems.

The most common places you find monophonic sound today are radio talk shows, telephone communication, hearing aids, public address systems, and AM radio.

When you have stereophonic sound available, you’re transmitting two independent signals through different channels into a speaker pair. This design replicates the sensation of hearing a live performance, even if the only sound on a recording is that of a person speaking.

The independent signals do an excellent job of emphasizing sounds in each channel to create more depth. It enables sound recreation for individual musicians and instruments from different areas.

Although stereo sound has some exciting benefits to consider, it also has one primary disadvantage. Unless a listener places themselves in the center between the two speakers, the experience will feel unbalanced. There is no way to correct the audio imaging that occurs based on physical placement.

What Are the Pros and Cons of Monophonic Sound?

Although most sound systems use the stereophonic approach today because of how recordings are generated, you can still find some distinct advantages to the single-channel methodology.

List of the Pros of Monophonic SoundList of the Cons of Monophonic Sound
• Everyone listening to the audio in the single-channel design can hear the same output from whatever speakers are in the vicinity.
• All of the sounds heard from the track are at the same volume level.
• Speech intelligibility is much easier to manage because of how the mono design reinforces vocals.
• Older music that focuses on mono mixes typically sounds better when using a monophonic speaker or home audio system.
• It’s less expensive to use this option for recording and reproduction when compared to stereo or surround sound options.
• The recording process is much easier to manage because the single track requires only basic equipment to obtain the sounds in the localized environment.
• There is no sound perspective when using monophonic sound.
• Since the volume levels are the same within the track, there isn’t any audio-based depth perception.
• The impact made by the audio with a single track isn’t as potent as it would be when there are two channels available through stereo.
• Most modern mixes are meant for stereo audio, which means the monophonic version can sound hollow, tinny, and unbalanced.
• Some people might hear an echoing effect, similar to brainwave entrainment, if the split audio signal between two ears has a momentary delay.

Monophonic sound works best for home entertainment systems that want to include an AM radio, turntables, or older equipment. If you’re going to listen to anything else, the better option is to invest in stereophonic products.

What Are the Pros and Cons of Stereophonic Sound?

Stereophonic sound uses reproduced signals with level and phase relationships so that an image of the original source is hearable to the average listener. That’s why the independent tracks often feel like they have a direction to them, even if you’re standing still between two speakers in your living room.

List of the Pros of Stereophonic SoundList of the Cons of Stereophonic Sound
• It offers sound perspective to each listener, making it feel that a recorded track is closer to a live performance than the mono experience.
• Since the audio provides signals that make it feel like you know how vocals or an instrument were recorded, the impact has more influence on the listener’s overall enjoyment.
• This structure allows for multi-track recordings to add depth and clarity to any musical genre.
• Most artists and labels record in stereo sound today, a format that’s been promoted since the late 1960s.
• It’s considered the standard setup for almost every situation, including movies, television, and PA systems.
• You can avoid having music or vocals sound like they come in clusters with this technology, even if you’re only wearing headphones or earbuds.
• Recording audio with stereophonic sound is more complex than mono, requiring advanced technical skills and knowledge to complete the independent tracks.
• The equipment used in the speakers to create a stereo response is more complex, which means it typically comes at an additional cost.
• It is a little harder to edit stereo files than it is to manipulate monophonic ones because you have multiple tracks to adjust instead of a single recording.
• The only way to genuinely benefit from the multi-track design is to find the perfect spot between two speakers with left and right track designations.

When you have stereophonic sound available at home or through your entertainment equipment, the outcome creates a more immersive listening experience.

Even if you’re not directly centered between a couple of speakers, you’ll still notice the difference that having two tracks makes compared to the singular mono channel.

What You Need to Know About Interaural Level and Time Differences

When you hear a blended audio experience from two or more channels, it becomes possible for the stereo system to create phantom images. That means your brain thinks that the sound comes from the middle space between the speakers instead of the right and left channels alone.

That outcome is referred to as the “stereo image.”

One of the cues that helps create that process is called the ILD (interaural level differences). It’s the changes in sound levels between your left and right ears.

Since soundwaves get reduced over a distance, the audio becomes quieter as it travels further. That means when sound originates in front of you, the time it takes to reach either ear is similar, which means the volume sounds relatively identical.

If the audio is on your left side, what you hear will be louder in that ear than it is on the right. The opposite is the case if you hear something in reverse.

That’s how a stereo image gets created. By panning the audio between the channels, the tracks fool the brain into thinking that something is present in the environment when it is not.

Another option is called the ITD (interaural time differences). Since soundwaves travel at a specific speed, audio that originates from one side of the body will reach the ear faster than it will on the other. Your brain will tell you where it thought it heard the transmission point because of this effect.

When you listen to music in mono, this information disappears from the output. Although you could hear multiple sound points through your equipment, the result is that the equal mix feels flat and uninspiring because there’s no variety.

This outcome happens because of the Haas Effect. The ITD is so potent that sounds with equal volume will still have an origination point when the sound waves reach one ear before the other.

That’s why some mixes include delays in one track. It adds perception to the listening perspective, even if all of the audio cues are present with equal volume.

If you have a stereo microphone, you can produce a similar result when broadcasting your voice throughout a PA system.
