Sound Design Music Production and Mixing Fundamentals 2

Question 1

What is 'stem mixing' in music production?

Accepted Answer

Exporting or mixing a project as grouped sub-mixes (drums stem, bass stem, vocals stem) rather than a single stereo bounce

Answer

Stem mixing exports a project as multiple sub-mix files grouped by instrument category (drums, bass, keys, vocals), giving mastering engineers or remixers more control than a single stereo mix but less granularity than full multi-track sessions.

Question 2

What does 'BPM' stand for in music production?

Accepted Answer

Beats Per Minute — the measurement of musical tempo

Answer

BPM (Beats Per Minute) is the standard unit for measuring musical tempo — the number of beats that occur in one minute — used in DAWs, drum machines, and sync licensing to specify or match the speed of a piece.

Question 3

What is a 'VU meter' in audio?

Accepted Answer

A volume unit meter that measures average signal levels based on a ballistic response approximating human loudness perception

Answer

A VU (Volume Unit) meter uses a ballistic averaging response similar to human perception of loudness (300 ms integration time), historically used on tape machines and consoles — 0 VU nominally corresponds to +4 dBu in professional audio.

Question 4

What is 'side-chain EQ' used for in mastering?

Accepted Answer

Using a filtered version of the input signal to trigger a compressor, so the compressor only reacts to specific frequencies

Answer

Sidechain EQ filters the detector signal of a compressor so that only specific frequencies (e.g., harsh sibilance at 8 kHz) trigger the compression — this is the basis of de-essing, where compression only activates when sibilant frequencies exceed the threshold.

Question 5

What is a 'reference track' used for in mixing and mastering?

Accepted Answer

A commercially released song used as a sonic benchmark to compare tonal balance, loudness, and dynamics against the mix being worked on

Answer

A reference track is a well-produced, commercially released song in a similar genre that the engineer imports into the session to A/B compare against the work-in-progress, helping calibrate EQ, compression, and loudness decisions.
