What is clipping clamping?

Clipping occurs when amplified audio samples exceed the maximum digital value. Clamping prevents this by hard-limiting any sample that would exceed the ceiling, avoiding harsh distortion.

What is a safe gain range?

For most recordings, a gain of 1.5× to 2× is safe and sounds natural. Going above 3× can introduce noticeable clamping artefacts on loud passages.

What does a 2× gain actually mean?

A 2× gain multiplies every audio sample by 2, which is roughly equivalent to a +6 dB increase in loudness.

What is the difference between boosting and normalising?

Normalisation raises the volume so the loudest peak just touches 0 dBFS, which is a fixed, automatic result. Boosting lets you choose an arbitrary multiplier, giving you more control.
