How is balance different from panning?

Panning applies a gain law that moves the image, raising one side as it lowers the other, which is what you want when placing a source. Balance only attenuates, leaving the other channel untouched, so the centre of the image stays where it is. Use balance to correct a leaning recording and pan to position one.

Why can it only reduce level?

Because attenuation cannot clip. Boosting a weak channel risks pushing the output past full scale with no metering to warn you, while turning the loud side down is always safe. The consequence is that the corrected file is quieter overall, which is the trade the tool asks you to accept.

What if one side is actually broken rather than quiet?

Then balance will not help. A channel that is distorted, delayed or missing content sounds wrong for reasons other than level, and turning the other side down simply makes the problem quieter without fixing it. Polarity and timing problems in particular need their own tools.

Does the untouched channel really stay identical?

Yes, and it is verified behaviour. The tool applies a gain to one channel only, so the other passes through with no filtering, no crosstalk and no gain change, and it is reproduced sample for sample. The footer states this explicitly so you can trust the half of the file you did not ask it to touch.

Will balancing affect mono compatibility?

It changes the mono sum, since one channel now contributes less than before. That is usually exactly what you want, because a leaning stereo mix folds down to a mono signal that also leans. Check the fold down after the pass if mono playback matters for the material.

Balance Adjuster attenuates one channel of a stereo file without touching the other, which is the cure for a mix that leans to one side. It is deliberately not a pan control: nothing moves, one side is simply turned down.

What is Balance Adjuster?

Drag the balance slider and one channel is scaled while the other is left exactly as it was. The footer names which side was attenuated and by how much, and states that the untouched channel is bit identical to the source.

What the control does:

A slider from full left to full right, centred and at unity by default.
Attenuation in one direction at a time: moving toward the left turns the right channel down, and moving toward the right turns the left channel down.
A readable label naming the attenuated side and the percentage applied to it.
A footer guarantee that the untouched channel is bit identical to the input.
A two channel requirement and an output WAV named after the source with a balanced suffix.

The adjustment is a gain applied to a single channel of the pair. At the centre both channels pass at unity, and as the slider moves to one side the opposite channel is scaled down while the near channel stays at full level, which is why nothing about the image moves and the effect is a pure level correction. Verified behaviour is that the untouched channel is reproduced sample for sample, with no filtering, no crosstalk and no gain change of any kind. That makes it the right tool for a genuinely leaning mix, where one microphone or one side of a stereo capture came back quieter and the fix is to bring the two sides level rather than to reposition anything.

What it cannot fix:

It only attenuates, so a weak side cannot be boosted; the alternative is to turn the loud side down and accept a quieter file.
It cannot tell you how far off the balance is, because there is no metering and no level readout.
It will not correct a timing or polarity problem, either of which can make one side sound wrong without being a level matter at all.
The correction is static, so a file whose balance drifts over its length needs more than one pass or a different approach entirely.
Scaling one channel changes the summed mono level, so a fold down after balancing will differ from the original.
It applies to the whole file, so it cannot rebalance individual elements inside a mix.

It helps to be clear about which of the two stereo corrections you are making. If the material sounds as though everything has shifted sideways while keeping its shape, the balance is what needs fixing, and attenuating the loud side is exactly right. If a single element is in the wrong place while the rest of the mix is fine, that is a mixing decision the file cannot help with, since this tool acts on the two channels as a pair rather than on anything inside them. Use it when the mix already sounds correct but sits off centre, and because the correction is attenuation, the louder channel sets the level after the pass, so decide whether a slightly quieter file is acceptable before committing.

How to use Balance Adjuster

Drop a stereo file onto the panel; the tool needs two channels to balance one against the other.
Move the slider toward the side that is too loud, which attenuates the opposite channel.
Read the footer label to confirm which side is being attenuated and by what percentage.
Download the balanced WAV, knowing the untouched channel is bit identical to the source.

When to use Balance Adjuster vs related tools

Balance Adjuster is the corrective tool for a leaning mix, so it is the right first step when one side is simply louder. Panning Tool is the creative relative, moving the whole image rather than levelling it, and Channel Mixer is for cases where the two channels need rebuilding instead of adjusting. When the imbalance turns out to be a polarity problem rather than a level one, Left/Right Channel Swapper and the inverter tools address the cause rather than the symptom.
