Reference Target Waiting

Add a reference song to derive a tonal, dynamics and stereo target for the main mix.

Match amount 60% Controls how closely the main mix moves towards the reference profile. Use 40-60% for transparent masters; higher settings are deliberately capped to protect the original mix.

Input Gain 0 dBRaises or lowers level before EQ and compression. Bass Shelf 0 dBControls weight below roughly 120 Hz. Low-Mid Clean 0 dBCuts mud around 280 Hz or adds body if needed. Mid Focus 0 dBShapes vocal/instrument focus around 1.2 kHz. Presence 0 dBAdds or removes bite around 3 kHz. Air 0 dBControls shine above 9 kHz. Compression 20%Premium mastering uses gentle glue first. Push higher only when the mix needs more density. Saturation 10%Adds subtle harmonic density. Keep low for transparent streaming masters. Stereo Width 100%Live mid-side width. Use small moves; very wide masters can lose mono punch. Mono Compatibility 35%Gently reduces excessive stereo side energy to improve mono translation. Check the result by ear; this is not a substitute for mix correction. Limiter Ceiling -1 dBTPMaximum peak level allowed in the preview/export. Target Loudness -14 LUFSServer render uses this as the loudness goal. Live preview follows it gently so A/B stays honest. Output Trim 0 dBFinal level trim after tone and dynamics. Mix Amount 100%Blends dry original with mastered processing.

Preview export and server master

Preview export runs in the browser for fast decisions. Server Final uses the precision FFmpeg chain, then independently measures the encoded delivery file and reports its actual loudness, true peak and loudness range.
