Audio Application: Methods for Recording Correct Sound
1. Hardware Equipment Quality
Most home setups consist of three main components: microphone, audio interface, and headphones. Few purchase standalone preamps. The quality of these is controllable; higher-end equipment directly impacts recorded sound quality if budget allows.
For recording, which matters more: mic, preamp, or interface? Personal priority: Microphone > Preamp > Interface. The mic captures sound directly; its quality determines raw audio fidelity. Preamps only amplify signal strength and dynamic range. While different preamps color sound differently, the differences are subtle. Don't expect a premium preamp to fix a low-quality mic—"garbage in, garbage out." If your mic sounds muffled, even a top-tier preamp won't brighten it; it'll exacerbate muddiness. Allocate most budget to the mic. Most USB interfaces have built-in preamps—a good mic through an interface's preamp still delivers decent results.
Microphone polar patterns matter. Many overlook this, yet it's effective against environmental noise (if noise comes from one direction, e.g., outside windows). Point the mic's null zone (back of cardioid mics) toward noise sources. Most entry-level mics are cardioid, rejecting rear sound. This achieves clean recordings without cost. Condenser vs. dynamic mics: Some argue dynamics suit noisy environments. While valid, most record in bedrooms/dorms where reflections are minimal. Test by clapping loudly at your recording spot. If you hear pronounced flutter echo (comb filtering), use dynamics. If echo is faint, condensers work—they offer superior detail. Choose based on environment. Invest most in mics: e.g., with a ¥5000 budget, allocate ¥2500 to mic, ¥2000 to interface, ¥500 to headphones. Specific recommendations listed later.
Interfaces: Most use USB interfaces. Define needs before buying: Live performance with DAW rack? Pure recording? Need built-in DSP effects? For live/loopback, choose 4-in/4-out interfaces (e.g., Roland UA-55). For recording only, 2-in/2-out suffices (e.g., Steinberg UR22). For interfaces with EQ/compression/reverb, consider Motu Microbook II. Sub-¥2000 interfaces have similar recording quality; focus on features. Disable onboard compression/limiting while recording. Critical: Set input levels correctly—test record the song's loudest section to avoid clipping. Don't record too low to "reduce noise"; noise floor remains fixed, and mixing requires gain boost anyway.
Headphones: For recording, prioritize sound isolation and comfort. Avoid earbuds—their response is inaccurate, masking recording flaws. Over-ear monitoring headphones are preferable. Many affordable options meet basic frequency-response needs.
2. Recording Posture
Habits vary: sitting or standing. Don't force standing for "better breath" if uncomfortable—it hinders performance. Do strictly control mouth-to-mic distance. Under 10cm causes proximity effect—boosting bass, making sound muddy. Close distance also amplifies volume changes with minor head movements, complicating editing. Maintain at least one fist's distance (≈10cm). Adjust per vocal style: Distant for ethereal vocals (e.g., "Autumn Concentration"), closer for intimate songs (e.g., "Long Time No See")—but never under 10cm. Use a pop filter at fist distance as a physical limiter.
Unmentioned tip: Mic height affects tone. Higher placement captures more nasal/head resonance; lower placement emphasizes chest resonance. I've experimented: Dual-miking—main mic at mouth, secondary at chest—blended via level control yields rich, natural vocals needing minimal EQ. Position height based on desired tonal character.
3. Professional Attitude
I admire a singer who recorded 1000+ takes, but this often indicates insufficient song familiarity. Limit sessions to 2 hours max. Beyond this, vocal cords fatigue—causing poor tone and inconsistent timbre between early/late takes, which is hard to fix. Master the song before recording. Efficient sessions ensure consistent takes, easing editing—a win-win.
4. Technical Formats
Most know to save as WAV, but many overlook mono. For vocals, mono/stereo sound identical post-production, yet stereo doubles file size needlessly. Export settings control this. Standard industry format is 24-bit/48kHz. For CD, downsample to 16-bit/44.1kHz. Sample rate determines maximum recordable frequency (Nyquist theorem): 32kHz captures only up to 16kHz. Higher rates preserve more high-end. Use 44.1kHz if your interface lacks 48kHz support—never lower.
