Panning Stereo Recordings: Is It Possible?

can you pan a stereo recorded instrument

Panning is a process in audio and music production that involves positioning sounds at particular locations in the stereo image of a mix, creating a sense of space and depth. It is used to create a three-dimensional space where each element has room to breathe, enhancing the overall listening experience. By using techniques like LCR panning, the Haas Effect, microshifting, and double tracking, engineers can bring clarity and excitement to their mixes. In this process, a pan pot or slider is used to adjust the ratio of levels between the left and right output of a stereo audio signal, allowing for the creation of a wide, full-sounding mix. This technique can be applied to both mono and stereo tracks, with stereo tracks offering more control over the location and width of the instrument in the stereo image.

Stereo panning techniques

Panning is the spread of a monaural signal in a stereo or multi-channel sound field. It is critical to the makeup of the stereo image. The centre of the sound field is usually the busiest part of a mix. Elements that ground the mix, such as kick, snare, bass, and vocals, are generally kept in the centre. However, feel free to experiment—rules can be broken!

For other instruments, pan left or right of the centre. Avoid hard panning, as extreme left/right panning can create clutter. Try to position sounds within subtle stereo zones. To maintain balance, use counterbalance panning: for each element panned one way, pan another in the opposite direction. Reduce masking by giving each instrument space to prevent sounds from overlapping. When two electric guitars play at once, they often compete for space.

If you can avoid cluttering up the midpoints in the stereo field, the far left and right points may sound even more dramatic and further out. This is known as the LCR technique, where each element is panned hard left, hard right, or centre, avoiding intermediate panning positions. However, you don't have to use it at all. Adopting it can be a great way to mix up your style and encourage you to put out some truly impressive and wide-sounding mixes.

Stereo instruments such as pianos, synths, and drum kits usually come on stereo tracks, which have balance pots rather than pan pots. Depending on how the instrument was recorded, it may sound unnaturally wide if left to its own devices, so it's worth thinking about inserting a plug-in that allows you to reduce the stereo width.

Stereo widening

Panning is a fundamental technique in stereo widening. It involves positioning sounds at specific locations in the stereo image, allowing you to control the width of stereo tracks. By panning instruments left or right, you can spread them out across the stereo image, creating a sense of depth and space. For example, placing a stereo recording of a piano hard left and hard right would spread the piano across the entire stereo image. Moving the pan pots inwards towards the centre would make the piano's width narrower.

Microshifting is another powerful technique for stereo widening. It involves duplicating a stereo track, panning one copy hard left and the other hard right, and then using a pitch-shifting plugin to adjust the pitch of each copy by a few cents. This creates a wider stereo image without changing the timbral qualities of the original audio signal.

Double tracking is a technique where you record a second, identical performance and layer it with the original. This helps to create a more pronounced separation between the tracks, adding depth and width to the stereo image.

Additionally, there are numerous third-party plug-ins dedicated to enhancing stereo width. Examples include Waves' PS22, Izotope's Ozone, and the PSP Pseudo Stereo and Stereo Enhancer plug-ins. These plug-ins offer various features, such as width control, EQ, and delay, to help create a wider stereo image.

It is important to note that while achieving a wide stereo image is desirable, maintaining mono compatibility is still crucial. Many playback systems, such as smart speakers and club sound systems, are still mono. Therefore, it is essential to consider factors like genre and instrumentation when employing stereo widening techniques to ensure your mix translates well in both stereo and mono environments.

Mono compatibility

Panning a stereo-recorded instrument can be done using two pan pots in many DAWs, such as Pro Tools. One pan pot controls the left side of the signal, while the other controls the right side, allowing you to manipulate the location and width of the instrument in the stereo image.

However, when it comes to mono compatibility, there are some considerations to keep in mind. Firstly, hard panning an instrument to one side in a mono mix can result in an imbalance in the overall mix. This is because the panned instrument may struggle to fulfil its musical function when competing with other instruments typically found closer to the centre, such as bass, kick, snare, and lead vocals. To avoid this issue, it is recommended to leave a third version of the track panned in the centre at a lower volume to maintain mono compatibility and address phase issues.

Additionally, when a stereo mix is collapsed to mono, the balances between instruments will change. This is because the apparent level of an instrument panned from left to right will sound louder when summed to mono and placed in the centre compared to when it is hard panned. This was recognised as early as the 1950s and 1960s, when separate mixes were made for mono and stereo releases.

To address mono compatibility concerns, it is advised to compare your mix against commercial productions in mono. While conventions on stereo imaging vary, using a stereo vectorscope display for your DAW can help identify potential mono phase-cancellation problems. Furthermore, when panning mono sources, it is suggested to avoid panning beyond 85% to either side, as this can make it challenging to blend the sounds convincingly, especially in headphones.

Lastly, when recording a stereo-recorded instrument with a left and right microphone, sound engineers recommend panning the tracks hard left and right in your DAW to avoid phase issues. This leaves some trace elements of the sound in the second speaker, mimicking how sound is naturally picked up by our ears.

Binaural hearing

Panning a stereo-recorded instrument involves using two pan pots to control the position of the left and right sides of the signal. This allows you to determine the location of the instrument in the stereo image, as well as how wide or narrow it sounds. The process of positioning instruments from left to right and adjusting their width is known as panning, and it helps create an immersive soundscape. Binaural hearing refers to the way humans hear using two ears, allowing us to perceive sound from two different points in space.

Our binaural hearing system enables us to map sounds, differentiate loudness, determine proximity, and separate voices from background noise. This is achieved through the brain's ability to process sound from both ears, creating a three-dimensional perception of sound. Binaural hearing provides a balanced perception of sound, enhancing sound quality and improving balance. It is critical for communication and spatial awareness, reducing the risk of accidental falls associated with hearing loss.

The advantages of binaural hearing are evident in various situations, especially in the presence of background noise. Individuals with unilateral hearing loss often struggle to understand speech in noisy environments and face challenges in localizing sounds. Binaural hearing aids improve the user's ability to interpret sound by providing a more comprehensive and accurate perception of their surroundings.

In audio production, panning techniques aim to create an immersive experience by sculpting a full, rich stereo image. By utilizing tools like LCR panning, the Haas Effect, microshifting, and double tracking, engineers can enhance depth and clarity in their mixes. This results in a three-dimensional space where each element, including instruments, has room to breathe.

To ensure mono compatibility, it is recommended to leave a third version of the track panned in the center at a lower volume. Additionally, techniques like reverb, EQ, and stereo imaging plugins can be intentionally employed to enhance the overall stereo image.

Stereo imaging

One of the fundamental tools for stereo imaging is panning, which allows for the precise positioning of instruments and sounds within the stereo field. Panning enables engineers to place sounds at specific locations between the left and right speakers, creating a sense of space and width. This technique is particularly useful for stereo-recorded instruments, as it gives control over the location and width of the instrument within the stereo image.

For instance, consider a stereo recording of a piano captured using two microphones. Panning allows you to place the piano across the entire stereo image by setting the pan pots to hard left and hard right. Alternatively, moving each pan pot towards the centre by 50% would narrow the width of the piano while keeping it centred.

It's important to note that panning is a creative process without a one-size-fits-all approach. The specific panning positions may vary depending on the desired effect and the characteristics of the instruments. For example, hard panning, where instruments are placed at extreme left or right, is commonly used to create a wider and more powerful stereo image, especially in rock genres. However, it may not always be feasible due to stereo setup inconsistencies.

Additionally, stereo imaging techniques can be combined with other tools such as reverb, EQ, and pitch shifting to further enhance the spatial perception of the audio. By paying attention to mono compatibility and using these tools intentionally, engineers can create a balanced and immersive stereo image that complements the music and provides a unique listening experience.

Frequently asked questions

Audio panning is a process in audio and music production used to position sounds in the left-to-right spectrum of a stereo image. It is done using a pan pot or slider that adjusts the ratio of levels between the left and right output of a stereo audio signal.

Stereo channels usually have two pan pots. One controls the position of the left side of the signal, and the other controls the position of the right side. This allows you to control the location of the instrument in the stereo image and how wide or narrow it sounds. For example, placing the pan pots hard left and hard right would spread the instrument across the entire stereo image. Moving each pan pot towards the centre by 50% would make the instrument's width narrower.

It is recommended to start your mix with panning. It is also important to always check your mix in mono to ensure you are not losing too much in the fold-down. Additionally, when mixing two guitars, it is common to pan them on different sides to create a wider and more powerful stereo image.
