Question 1

In a DAW, what is the difference between 'pre-fader' and 'post-fader' sends?

Accepted Answer

Pre-fader sends are tapped before the channel fader, so the send level is independent of the fader; post-fader sends follow fader movement

Answer

A pre-fader send taps the signal before the channel fader, making the effects return level independent of the channel's mix level — useful for headphone monitor mixes. A post-fader send is tapped after the fader, so lowering the channel fader also reduces the effect send.

Question 2

What is 'audio quantization' in a DAW, and when is it applied?

Accepted Answer

Snapping recorded audio or MIDI events to the nearest grid position to correct timing inconsistencies

Answer

Audio quantization in a DAW refers to snapping audio regions (or transients within regions using elastic audio) to the timing grid to correct performances that are slightly ahead or behind the beat. It originated as a MIDI function but is now applied to audio in modern DAWs.

Question 3

What does 'freeze track' functionality in a DAW accomplish?

Accepted Answer

Renders the track's audio with all its plugins to a temporary audio file, freeing CPU resources while keeping the original settings

Answer

Freezing a track renders it with all its insert plugins to a temporary audio file and disables plugin processing, reducing CPU and memory load. The original track and settings are preserved; unfreezing restores full editability.

Question 4

What is the purpose of 'clip gain' (region gain) in modern DAWs, separate from channel fader level?

Accepted Answer

It adjusts the level of individual audio regions before they reach insert plugins and the channel fader, useful for balancing takes within a track

Answer

Clip gain (region gain) adjusts the level of individual audio clips before they pass through insert plugins and the channel fader. It is useful for correcting level inconsistencies between takes on the same track without affecting the processing chain or fader automation.

Question 5

In DAW-based recording, what does 'varispeed' (or 'pitch-locked time stretch') allow an engineer to do?

Accepted Answer

Change the tempo of a session while maintaining the original pitch of recorded audio

Answer

Modern DAWs can stretch or compress audio in time while maintaining the original pitch (time stretching) to accommodate tempo changes. 'Varispeed' in the traditional sense changes both speed and pitch simultaneously (like tape); modern pitch-locked stretching separates the two.
