FAQ: Production Choices Decoded

No. Digital summing is simple addition of sample amplitude values. Whether a host runs a 32-bit floating-point or 64-bit floating-point mix bus, exporting identical dry audio tracks at unity gain with identical pan laws (-3.0 dB, -4.5 dB, or -6.0 dB) results in files that cancel out to digital silence when polarity-inverted. Differences arise only when a DAW enables default time-warping (e.g., Ableton’s auto-warp on long samples) or loads an optional analog console emulation plugin across mix channels.

AU (Audio Units) is Apple’s native macOS/iOS standard (required by Logic Pro). VST3 is Steinberg’s cross-platform standard supporting dynamic I/O configuration and silent-audio CPU sleep. CLAP (Clever Audio Plug-in) is an open-source, MIT-licensed standard initiated by u-he and Bitwig that allows host DAWs to modulate parameters per polyphonic voice without overwriting the user’s knob position. Legacy VST2 is deprecated by Steinberg and should only be kept for opening older archival projects.

Replace a stock processor only when you encounter a specific workflow barrier: for example, if your stock equalizer lacks dynamic threshold bands for taming harsh vocal sibilance, or if your stock limiter lacks True Peak (ITU-R BS.1770-4) oversampling. Buying another static 5-band parametric EQ purely for "sound quality" will not change your mix.

For 95% of music production and video scoring, 48 kHz / 24-bit is the practical sweet spot. Running an entire project at 96 kHz doubles your CPU load and disk bandwidth. Instead, run the project at 48 kHz and enable 2x or 4x internal oversampling only on nonlinear saturation and limiting plugins that benefit from aliasing suppression. Record at 96 kHz or 192 kHz primarily when capturing foley or acoustic samples intended to be pitched down an octave or more during sound design.

Audio interfaces process sound in sample buffers (e.g., 64, 128, 512, or 1024 samples). Small buffers (64–128 samples) minimize round-trip monitoring delay during tracking, while large buffers (512–1024 samples) give your CPU breathing room during heavy mixing. However, even at a 64-sample buffer, inserting a "lookahead" limiter or linear-phase EQ on your master bus forces Plugin Delay Compensation (PDC) to delay the entire session. Enable your DAW’s "Low Latency Monitoring" mode while recording.

If your sessions rely primarily on algorithmic synthesizers (Vital, Serum, Diva, Surge XT) and audio stems, 16 GB of unified/system RAM is plenty, and CPU single-core performance is your main ceiling. If you compose with large multi-sampled orchestral templates in Kontakt or SINE, target 32 GB to 64 GB of RAM and store sample libraries on a dedicated PCIe NVMe SSD.

Subscription bundles let you audition dozens of tools cheaply for a month, but if you pause your subscription a year later, older DAW projects using those plugins will open with disabled insert slots unless you printed stems. Many producers prefer perpetual licenses or free/open-source staples (Surge XT, Vital, TDR Nova) for core mix-bus duties so old sessions always remain editable.

Standard MIDI sends pitch-bend and aftertouch across an entire channel—bending one note bends every held chord note simultaneously. MPE assigns each note its own MIDI channel under the hood so you can vibrate a single lead note while holding a steady pad chord beneath it. Even without an MPE hardware controller, you can draw per-note pitch and pressure curves by hand inside Ableton Live 12, Bitwig Studio 5, and Logic Pro 11.
