Digital Audio Workstations (DAW) Flashcards

What is the purpose of 'stem exports' when delivering a completed DAW project?

Answer: To export grouped sub-mixes (e.g., drums, bass, vocals) as separate audio files for remixing, re-editing, or post-production

Stem exports render audio in grouped categories (drums, bass, guitars, vocals, FX) rather than as a single stereo mix. This gives recipients the ability to adjust relative blend between stems, create remixes, or re-mix for different formats without access to the full session.

What is 'AAF' (Advanced Authoring Format) used for in DAW workflows?

Answer: A project interchange format that carries multi-track audio, edits, and metadata between different DAW platforms

AAF is a media exchange format that encapsulates multi-track audio, edit decisions, fades, and metadata. It allows DAW sessions to be transferred between platforms (e.g., Avid Pro Tools, Adobe Premiere, DaVinci Resolve) preserving the edit structure and timing of the project.

In DAW mixing, what does 'automation' allow the engineer to do?

Answer: Record and playback changes to parameters (fader levels, pan, plugin settings) over time during playback

Automation records changes to mix parameters — faders, pan, sends, plugin knobs — as time-based data that plays back automatically. This allows dynamic, expressive mixes where levels, panning, and effects evolve throughout the song.

What does the term 'headroom' refer to when setting recording levels in a DAW?

Answer: The available dynamic range between the nominal recording level and the maximum digital ceiling (0 dBFS) used as a safety buffer against clipping

Headroom is the difference between the typical operating level and the maximum level before clipping (0 dBFS in digital systems). Leaving 6–12 dB of headroom during tracking prevents unexpected peaks from causing hard digital clipping, which is unrecoverable unlike analog tape saturation.

What is 'sidechain routing' used for in DAW-based production?

Answer: Feeding the signal from one track into the key input of a dynamics processor on another track to trigger gain reduction

Sidechain routing feeds an external trigger signal into the key input of a compressor, gate, or other dynamics processor. A classic application is ducking: feeding the kick drum into the sidechain of a bass compressor so the compressor only acts when the kick hits.

What is the significance of 'sample rate' selection (e.g., 44.1 kHz vs. 96 kHz) when setting up a DAW session?

Answer: Higher sample rates capture higher frequency content and provide more accuracy in digital-to-analog conversion, at the cost of larger file sizes and increased CPU load

Sample rate defines how many times per second the audio is sampled, determining the highest reproducible frequency (Nyquist = sample rate / 2). 44.1 kHz captures up to 22.05 kHz; 96 kHz captures up to 48 kHz. Higher rates improve accuracy of anti-aliasing filters and analog modeling plugins, but increase storage and CPU requirements.
