Question 1

What is the primary purpose of a high-pass filter (HPF) on most non-bass instrument tracks?

Accepted Answer

Remove unwanted low-frequency rumble and mud

Answer

HPFs eliminate sub-bass energy on non-bass instruments that clutter the low end without contributing musically.

Question 2

In the context of mix translation, what does it mean when a mix 'translates well'?

Accepted Answer

The mix sounds balanced across various playback systems

Answer

Good translation means the mix sounds consistently balanced on headphones, car stereos, club systems, and consumer speakers.

Question 3

What is 'inter-sample peaking' and why is it important in mastering?

Accepted Answer

Peaks that occur between sample points during D/A conversion that can cause clipping

Answer

Inter-sample peaks exceed 0 dBFS during reconstruction, causing distortion on decoders even when the waveform shows no clipping.

Question 4

Which metering standard is most commonly used for streaming platform loudness normalization?

Accepted Answer

LUFS (Loudness Units Full Scale)

Answer

LUFS is the integrated loudness measurement standard used by Spotify, Apple Music, YouTube, and other platforms for normalization.

Question 5

What is the function of M/S (Mid-Side) processing in mastering?

Accepted Answer

It allows independent EQ and compression of the center and side signals

Answer

M/S processing decodes stereo into mid (center) and side (difference) components, enabling targeted treatment of each element.
