BIG: widen a stereo relationship, then check its foundation

Start with a source that already has a stereo relationship

BIG derives its added image from side information. A stereo room, overhead pair, keyboard print or background texture can therefore be a useful source. An identical left-right mono signal does not provide the same material for the image process. Begin by hearing what is actually different between the two channels.

Choose a phrase with a stable centre and useful stereo detail. Keep the kick, snare, lead or bass reference available in the arrangement. The aim is to give the selected source a useful spread without making the whole musical picture feel less focused.

Know what cancels and what still changes

Range selects the region involved in the added image, Stage shapes its character and BIGNESS controls the side-derived contribution. That added component cancels in mono before common level compensation and the optional BASS shelf. The complete mono output is therefore not a promise of an entirely untouched signal.

BASS adds a low shelf to both channels. It is not a crossover that makes all bass mono. Compare that tonal decision separately from image shaping, and use a sensible level comparison when deciding whether the wider version is actually more useful.

Workflow one: open a stereo drum room

Use the room or overhead pair beside the close kit and bass rather than widening every drum track together.

1. Begin with restrained BIGNESS and choose Range around the stereo material that should become more apparent.
2. Move Stage while hearing the room's tone and the placement of the main snare.
3. Raise BIGNESS only until the room contributes the desired spread.
4. Compare BASS off and on as a separate tonal choice.
5. Check stereo and mono at comparable levels, including the kick's relationship to the bass.

If the room becomes detached from the close hits or cymbal detail dominates the image, reduce the contribution or reconsider Range and Stage. A more spacious room is useful when the kit still feels like one instrument rather than two unrelated stereo layers.

Workflow two: place a stereo keyboard behind a lead

A keyboard texture can occupy the sides while a singer or lead instrument remains clearly in the centre.

1. Balance the keyboard first and confirm that the source contains stereo information rather than duplicated mono.
2. Use a restrained BIGNESS setting and select a useful Range for the part's upper or middle texture.
3. Adjust Stage for the character that sits behind the lead, then recheck the chord progression.
4. Compare the mono sum, including any change from common gain compensation and BASS.

If a wider impression makes the lead seem smaller, the keyboard may simply be too loud or too dense. Reduce its level or the image contribution before asking for more width. Check the lowest chord as well as the brightest one.

A creative use: let a background layer expand at a section change

Use host automation to increase BIGNESS on a stereo ambience or sustained synth layer during a planned transition. Keep the central rhythm and lead stable while the background expands. A small movement can make the new section feel more open without changing the direct instruments' pan positions.

Hear the transition in mono too. Although the added side contribution cancels there, common level compensation and any BASS setting remain relevant. The musical contrast should not depend on assuming an unchanged mono output.

Keep the source's centre understandable

After the width decision, return to the original source and compare at a fair level. Listen for a stable centre, a useful spread and low-frequency balance that still belongs to the arrangement. A meter or a large BIGNESS value does not establish those outcomes.

Keep BIG when it develops an existing stereo relationship in a way the music needs. If the source is effectively mono or the wider version weakens the arrangement's focus, choose a different arrangement role rather than expecting the processor to invent the same result from every input.
