Hard Panning: When And Why?

Hard panning is a mixing technique that involves placing sounds at the extreme left or right of the stereo field. While it can be used to create a fuller-sounding mix, hard panning has fallen out of favour in modern mixing due to its detrimental effects on the overall mix. Instead, mix engineers tend to stick to more moderate pan settings to maintain an immersive sound field.

Hard panning can undo the illusion of a wider stereo field

Hard panning can have unintended and detrimental effects on your mix. When you pan hard left or hard right, your sound is only coming out of one speaker. This can undo the illusion of a wider stereo field, 'pinning' the sound to just one speaker and making it stand out unintentionally in the context of the mix because it sounds artificial.

Our brains resolve the two sides of a stereo sound to a phantom "centre", even though the sounds are coming from two separate physical speakers. When you hard pan, you are sending the sound to only one speaker, which can make it sound unnatural.

To maintain the immersive sound field, it is recommended to pan only to around 90% at a maximum, which preserves the sense of shared depth with other, less widely panned tracks. This is known as LCR panning, where you pan instruments to the left, centre, or right channels, providing plenty of space between instruments and helping to create a wide-sounding mix.

One of the goals of panning is to create a wide stereo image, but simply hard panning instruments left and right will not create the desired effect. Instead, you need to carefully place instruments throughout the stereo spectrum and use some plug-ins to help enhance the illusion.

One quick way to make your tracks sound wider is to duplicate a track and pan them hard left and right. However, this is essentially the same as listening in mono. By applying time-based processing like a delay to one of the tracks, you can create a psychoacoustic effect that causes the listener to think they are two different signals, making the track sound significantly wider. This is known as the Haas Effect or the precedence effect.

Hard panning can cause frequency clashing

Frequency-dependent panning is a technique where different rules are applied to different frequencies. Low frequencies, for example, are typically not panned and remain in the centre due to their high energy. In contrast, high frequencies can be panned to create stereo width. This technique is especially useful when there are only a few instruments in the mix, such as a power rock trio with a guitar and bass. By panning the guitar to the left and the bass to the right, a sense of stereo width is created.

However, simply hard panning the bass instrument using a standard panning function can result in too much energy on one side, making the mix lopsided. This is where frequency-dependent panning comes in. There are plugins specifically designed for this purpose, such as Boz Pan Knob and TBProAudio ST1, or you can use a multi-band plugin like MeldaProduction's MSpectralPan to pan any frequency anywhere. Another option is to use buses and a filter/EQ plugin to send the bass instrument to two buses, low-pass one and high-pass the other, and then pan the high-passed track while leaving the other in the centre.

When deciding on panning techniques, it is important to consider the genre and style of the music. For example, in techno or house tracks, panning is usually very subtle, with most elements remaining centred to work on mono sound systems. On the other hand, older recordings or modern recordings trying to evoke a nostalgic vibe might use drastically different panning schemes, such as placing all the drums in one speaker and the rest of the band in another.

In conclusion, hard panning can cause frequency clashing, but this can be mitigated by using complementary panning techniques and being mindful of the overall stereo image. Frequency-dependent panning is a useful tool to separate low and high frequencies, creating a wider and more immersive mix while avoiding the issues that can arise from hard panning.

Hard panning may not translate well to mono sound systems

Hard panning is a technique used in music mixing to create a wider, fuller sound. It involves sending sounds to the extreme left or right of the stereo field, giving the impression of a larger stereo image. However, this technique may not translate well to mono sound systems, and there are a few reasons for this.

Firstly, when a mono track is hard panned off-centre, it can result in a reduction of its level in the mono balance by up to 3dB. This means that if a prominent instrument, such as a guitar riff, is hard panned to one side, it may lose impact when played back in mono. It will struggle to fulfil its musical function and may be overpowered by other elements that are typically centred in a mix, such as the bass, kick, snare and lead vocal.

Secondly, hard panning can cause phase issues and frequency-selective tone issues when summed to mono. This is because any stereo recording or stereo effect in the mix may contain elements in one channel that are out of phase or polarity-inverted compared to the other channel. When these channels are summed to mono, they can phase-cancel, resulting in a drop in volume or a change in tone. This is particularly common with stereo drum overhead mics and stereo piano recordings.

Additionally, hard panning in headphones can give the impression that the sound is coming directly from one ear, as there is no crosstalk between the earcups. This can be disorienting and make it challenging to blend the sounds in the mix convincingly. As a result, some engineers recommend panning mono sources to around 85% left or right instead of hard panning to maintain a more cohesive stereo presentation.

To ensure mono compatibility, it is essential to check the mix in mono and compare it to commercial productions. This will help identify any problems with balance, phase cancellation, or overall sound. By making adjustments and using other techniques, such as panning to the left, centre, or right channels (LCR panning), a wider soundstage can be achieved while maintaining mono compatibility.

In conclusion, while hard panning can create a more immersive listening experience in stereo, it may not translate well to mono sound systems. To cater to a wider range of listening environments, it is crucial to consider the mono compatibility of the mix and make adjustments as needed.

Hard panning can be disorienting on headphones

When you listen to a mix on headphones, you eliminate crosstalk, which is when the information from the right speaker reaches the left ear and vice versa. This means that hard-panned sounds become distracting because there is total separation between the left and right channels. As a result, you might feel compelled to undo bold panning or move sounds towards the centre, leading to a narrower mix.

To avoid this issue, it is recommended to stick to more moderate pan settings. For example, Joe Albano suggests panning to only around 90% at maximum to preserve the sense of shared depth with other tracks. This way, you can maintain an immersive sound field while avoiding the disorienting effects of hard panning on headphones.

Additionally, it is worth noting that our perception of the stereo field differs between speakers and headphones. With speakers, the sound coming from the left side will still be picked up by the right ear and vice versa. However, headphones eliminate this acoustic process, making it challenging to judge panning and other widening decisions accurately.

To address this issue, you can use tools like Waves' Nx plugin, which recreates the acoustics of a studio in headphones, enabling you to evaluate stereo width more effectively. By utilising such tools, you can ensure that your mix translates well across different listening devices and provides a consistent experience for your audience.

Hard panning may not be suitable for music played in clubs

Hard panning is a technique used in music mixing to create a sense of width and depth in a track. It involves placing instruments at extreme left or right positions in the stereo field, giving the impression of a wider and more immersive soundscape. While this technique can be effective in certain contexts, it may not be suitable for music played in clubs due to several factors.

Firstly, many club playback systems are mono, which means that hard-panned elements may be lost or significantly reduced in volume. In a mono system, the left and right channels are summed, and if there is a sound that is out of phase between the two channels, it can cancel itself out when played in mono. This can result in a loss of impact for certain elements in the mix. To avoid this issue, it is crucial to check the mono compatibility of the mix and ensure that all elements are still audible and well-balanced. Creating a mono version specifically for club playback can be a solution.

Secondly, hard panning can undo the illusion of a wider stereo field by "pinning" the sound to a single speaker. This can make the sound stand out unintentionally and sound artificial. To maintain immersion, it is recommended to pan only up to 90% at maximum, preserving a sense of shared depth with other tracks. This technique is especially important when considering the acoustics of a packed club, where sound can bounce off surfaces and create a functionally mono experience, even if the system is wired for stereo.

Additionally, hard panning can lead to phase issues, particularly with lower-frequency elements like bass and kick drums. Panning these elements can cause them to sound strange when played in mono, which is common in club settings. To avoid this, it is generally recommended to keep the low-end elements in the centre of the mix.

Lastly, hard panning may not provide the desired effect in a club setting due to the nature of sound projection and the listening environment. In a club, sound travels and reflects off surfaces, and listeners are rarely positioned in the ideal sweet spot between speakers. As a result, hard-panned elements may not be perceived as intended, and the mix may sound unbalanced.

In conclusion, while hard panning can be a useful tool for creating width and depth in a mix, it may not translate well to music played in clubs due to mono compatibility issues, acoustic challenges, and the potential for an unbalanced listening experience. To ensure the best results, it is essential to consider the specific context and make informed decisions about panning techniques.
