Hardware

How sound becomes a recording: sound waves, voltage, current, resistance, AC vs DC, grounding, and the transduction chain from vibration to digital signal.

How to choose a microphone: dynamic vs condenser vs ribbon, polar patterns (cardioid, omni, figure-8), phantom power, and which mic to use for vocals, guitar, and drums.

XLR, TRS, TS, and RCA cables explained — what balanced vs unbalanced audio means, why it matters for noise rejection, and how to wrap cables properly.

What an audio interface actually does: preamps, A/D conversion, gain staging, Hi-Z inputs, and DI boxes — the hub between your microphone and your DAW.

Sample rate vs bit depth explained — 44.1 vs 48 kHz, 16-bit vs 24-bit, the Nyquist frequency, what dither does, and how buffer size affects latency.

How to record vocals and acoustic instruments: mic selection, placement distance, pop filter setup, gain staging, monitoring options, and getting a clean take.

Vocal recording sessions: building a headphone mix singers can perform to, managing multiple takes and comping, light compression while tracking, and session psychology.

Stereo recording techniques compared: X/Y, ORTF, spaced pair, Blumlein, Decca tree, NOS, and binaural — when to use each and how they affect phase and width.

Mid/side recording and processing explained — how M/S encoding works, the sum and difference matrix, correlation meters, the goniometer, and using M/S EQ in mastering.

How to record electric guitar, bass, and keyboards — SM57 on a cab, DI boxes, pickup types, re-amping, and when to mic vs go direct.

Studio monitor guide: how speakers work, active vs passive, nearfield vs midfield placement, the equilateral triangle, boundary effects, and calibration.

Open-back vs closed-back headphones for recording and mixing — when to use each, building cue mixes for performers, and why headphone mixing requires extra care.

Home studio acoustic treatment: soundproofing vs sound treatment, bass traps, absorption panels, first reflection points, room modes, and what to prioritize on a budget.

Audio metering explained: peak, RMS, VU, and LUFS meters, gain staging targets through the signal chain, and how phase cancellation and comb filtering affect recordings.

How patchbays work: normalled, half-normalled, and open configurations explained — plus mults, Y-cables, TT connectors, and studio signal routing fundamentals.

MIDI protocol fundamentals, clock and sync between devices, and networked audio over Ethernet.

MIDI controllers, hardware synths, effects processors, and integrating external gear with your DAW.

How to solder audio cables: XLR and TRS pin assignments, basic soldering technique, cable testing with a multimeter, and diagnosing broken connections.

What to prepare before pressing record — templates, track naming, headphone mixes, backups, and session management.

Home studio gear guide: what to buy first, what can wait, why mic placement beats mic cost, and when upgrading your interface or monitors actually makes a difference.
