Recording, Mixing and Post-Production Processes
Recording fundamentals
Understand sample rate and bit depth: sample rate sets the highest reproducible frequency (the Nyquist limit is half the sample rate), and bit depth sets dynamic range. Common practice is 24-bit at 44.1 or 48 kHz. Know the difference between tracking, overdubbing and comping. Microphone technique, room treatment and phase alignment all affect capture quality before any processing.
The mixing process
Mixing balances level, pan, frequency and dynamics across tracks. Learn the tools: equalisation (subtractive before additive), compression (threshold, ratio, attack, release, make-up gain), gating, reverb and delay as time-based effects, and automation. Understand the difference between an insert (per-channel processing) and an aux send (shared effect bus). Know that compression reduces dynamic range and that attack and release shape how transients are treated.
Post-production
Post-production covers editing, cleaning, fades, loudness normalisation and delivery formats. Know that loudness is measured in LUFS and that broadcast and streaming targets differ; over-compression reduces perceived punch. Understand stems versus a full mix, and the importance of backing up sessions and documenting versions.
Traps
Questions confuse bit depth with sample rate, or claim compression raises overall loudness without make-up gain. Another trap is treating reverb as an insert when it is usually a send. Watch for the claim that a higher sample rate improves dynamic range (it does not; bit depth does). Also remember that mixing decisions should serve the song and the delivery format, not just meter readings.
Rule of thumb
Record clean and conservative, mix subtractively, and check the mix on multiple systems at reference level. If a mix sounds loud but flat, suspect over-compression rather than a level problem.
