Mixing Calculators
Pan law, EQ frequency, compression ratio, stereo width and phase calculators for mixing engineers.
Pan Law Calculator
Calculate left and right channel levels for different pan law settings and compare -3dB, -4.5dB and -6dB pan law curves in detail.
Bus Routing Calculator
Calculate level summation when combining multiple channels to a mix bus. Understand coherent and incoherent signal summing in depth.
Aux Send Calculator
Calculate wet/dry ratios and effect send levels for parallel processing chains. Essential for reverb, delay and compression sends.
EQ Frequency Calculator
Find EQ centre frequency, bandwidth and Q factor. Convert between octave width and Q values for precise parametric EQ adjustments.
Compression Ratio Calculator
Calculate output level, gain reduction and makeup gain for any compression ratio, threshold and input signal level. Free calculator.
Sidechain Calculator
Calculate sidechain filter frequencies and ducking timing synced to your track BPM. Essential for kick-triggered compression in mixes.
Stereo Width Calculator
Calculate Mid/Side levels from stereo width percentage and vice versa. See how stereo width adjustments affect mono compatibility.
Phase Calculator

Mixing Engineering Fundamentals
Mixing is the process of combining multiple audio tracks into a final stereo (or surround) output. It involves balancing levels, panning, equalisation, dynamics processing, and spatial effects to create a cohesive and polished sound.
Pan law determines how the level of a signal changes as it is panned from centre to one side. Without pan law compensation, a signal panned centre would appear louder than one panned hard left or right, because it is reproduced by both speakers. Common pan laws include -3 dB (equal power), -4.5 dB (compromise) and -6 dB (equal amplitude).
EQ (equalisation) is used to shape the frequency content of individual tracks. Understanding the relationship between Q factor and bandwidth in octaves is essential for precise EQ work. A Q of 1.414 corresponds to one octave bandwidth, while higher Q values create narrower, more surgical cuts.
