Mastering Rack Pack for Ableton Live 12 — 6 Master-Bus Racks (Stock Devices Only)

Six master-bus racks whose Limiter ceiling is set to -1.0 dB, the maximum true peak Spotify's own loudness page asks uploads to stay under; built only from devices already inside Live, so nothing is added on top of the $749 USD Ableton lists for Live 12 Suite.

Streaming Master Bus

All-round master bus for a finished stereo mix going to streaming platforms.

The decision most tutorials skip: Live's Limiter measures sample peaks, not true peaks. A ceiling of 0.0 dB still clips after MP3/AAC encoding, because the encoder reconstructs peaks between samples. The ceiling here is -1.0 dB, which is also the maximum true peak Spotify's loudness page asks uploads to stay under. Saturator runs at 35% wet so the harmonics are added in parallel and the transients survive.

Signal chain: EQ Eight → Saturator → Utility → Limiter

#	Device	Control	Value	What it does
1	EQ Eight	`Band 1 filter type (12 dB low cut)`	1	A gentle low cut instead of a steep one - it removes rumble without the phase smear a 48 dB slope adds right where the kick lives.
		`Band 1 Freq (Hz)`	28	Cuts DC offset and subsonic rumble that eats limiter headroom while being inaudible on any speaker.
		`Band 2 Freq (Hz)`	240	The boxy build-up region on most home-studio mixes.
		`Band 2 Gain (dB)`	-1.5	A small cut, not a fix - on a master anything past 2 dB means the mix should be revisited.
		`Band 2 Q`	1.2	Wide enough to sound like a tone change, narrow enough to leave the low mids of vocals alone.
		`Band 3 filter type (high shelf)`	5	A shelf, not a bell, so the air lifts evenly instead of ringing at one frequency.
		`Band 3 Freq (Hz)`	9500	Above the harshness zone, so it adds air without adding sibilance.
		`Band 3 Gain (dB)`	1.0	1 dB of air is audible on a master; 3 dB is a mix decision, not a master decision.
		`EQ output (dB)`	-0.5	Gives back the level the shelf added, so the Saturator downstream is driven by your mix, not by the EQ.
2	Saturator	`Drive (dB)`	2.5	Enough to generate harmonics, low enough that the peaks are not reshaped before the limiter sees them.
		`Dry/Wet`	0.35	35% wet is parallel saturation: the untouched signal keeps the transients, the saturated one adds the density.
3	Utility	`Gain (dB)`	1.0	One clean control to push the limiter harder or softer without retouching the EQ or the drive.
4	Limiter	`Ceiling (dB)`	-1.0	Live's Limiter is a sample-peak limiter. 1 dB of headroom is what covers the inter-sample peaks a lossy encoder creates, and it matches the -1 dB true peak Spotify's loudness page asks for.
		`Release (ms)`	200	200 ms is slow enough not to pump on sustained bass and fast enough to recover before the next downbeat in most tempos.
		`Gain (dB)`	1.5	The only control you move while listening: raise it until your meter reads your target loudness, then stop.
		`Auto release (off)`	False	Off on purpose - a fixed release keeps the recovery time predictable so the same setting behaves the same across your whole EP.

Hip Hop 808 Master Bus

Master bus for hip-hop and trap where a sustained 808 carries the low end.

The decision most tutorials skip: with a sustained 808, a fast limiter release recovers between the note's own cycles and you hear it breathing. Release is 300 ms here, long enough to sit through an 808 tail. The low cut is steep (48 dB) at 24 Hz so it removes rumble without touching a 30-40 Hz fundamental, and Saturator runs hard so the 808 generates harmonics you still hear on a phone speaker that reproduces nothing below 200 Hz.

Signal chain: EQ Eight → Saturator → Utility → Limiter

#	Device	Control	Value	What it does
1	EQ Eight	`Band 1 filter type (48 dB low cut)`	0	A steep slope so the cut lands below the 808 fundamental instead of thinning it.
		`Band 1 Freq (Hz)`	24	Below a low 808; removes only what no system reproduces but every limiter reacts to.
		`Band 2 Freq (Hz)`	300	Where 808 harmonics and vocal body pile up and the mix turns muddy.
		`Band 2 Gain (dB)`	-2.0	Clears room for the vocal without pulling weight out of the 808 itself.
		`Band 2 Q`	1.0	Broad enough to be a tonal move rather than a surgical notch.
		`Band 3 filter type (high shelf)`	5	Lifts hats and the vocal top evenly.
		`Band 3 Freq (Hz)`	10000	High enough that it brightens hats without sharpening sibilance.
		`Band 3 Gain (dB)`	0.8	Under 1 dB - modern trap masters are already bright at the source.
2	Saturator	`Drive (dB)`	6.0	Generates upper harmonics of the 808, which is what a phone or laptop speaker actually plays back.
		`Dry/Wet`	0.4	40% keeps the dry sub intact underneath while the saturated copy supplies the harmonics.
3	Utility	`Gain (dB)`	0.5	Small offset so the Saturator drive above and the limiter push below stay independent.
4	Limiter	`Ceiling (dB)`	-1.0	Sample-peak limiter, so 1 dB is left for the inter-sample peaks created when the file is encoded.
		`Release (ms)`	300	Long enough to hold through an 808 tail; a short release on sustained bass is what makes a trap master breathe between notes.
		`Gain (dB)`	2.0	The push. Raise until your meter reads your target, then leave the ceiling alone.

Club Techno Master 128 BPM

Master bus for four-to-the-floor club material at 128 BPM.

The decision most tutorials skip: the limiter release is timed to the grid, not chosen by ear. At 128 BPM a bar is 60/128 x 4 = 1.875 s, so one 16th note is 117 ms. Release is set to 117 ms, which lets the limiter recover between kicks instead of across them. If your track is not 128 BPM, recompute: release ms = 60000 / BPM / 4 (the free web tool does it). Width is 95% because a wide mix folded down on a mono club sub is where wide masters fall apart.

Signal chain: EQ Eight → Saturator → Utility → Limiter

#	Device	Control	Value	What it does
1	EQ Eight	`Band 1 filter type (12 dB low cut)`	1	Shallow slope keeps the kick's phase behaviour intact - on a club system that matters more than the last 2 Hz.
		`Band 1 Freq (Hz)`	32	Below the kick fundamental of most techno kicks, above the rumble that steals headroom.
		`Band 2 Freq (Hz)`	180	The boxy shoulder of a layered kick.
		`Band 2 Gain (dB)`	-2.0	Gives back the punch a stacked kick loses to its own low mids.
		`Band 2 Q`	1.4	Tighter than the streaming rack because the target is one resonance, not a whole region.
		`Band 3 filter type (high shelf)`	5	Even lift across hats and top-end texture.
		`Band 3 Freq (Hz)`	11000	Air region only - big rooms already emphasise 3-6 kHz.
		`Band 3 Gain (dB)`	1.2	Enough to be heard over a loud system without turning hats harsh.
2	Saturator	`Drive (dB)`	4.0	More than the streaming rack: club masters are pushed harder and the harmonics do part of the loudness work the limiter would otherwise do.
		`Dry/Wet`	0.5	Half wet - audible weight, transients still intact.
3	Utility	`Width`	0.95	95% pulls the sides in slightly so nothing cancels when the club PA sums the low end to mono.
		`Gain (dB)`	1.0	Trim into the limiter, kept separate from drive.
4	Limiter	`Ceiling (dB)`	-1.0	Headroom for inter-sample peaks after encoding; also the -1 dB true peak Spotify's loudness page asks for.
		`Release (ms)`	117	One 16th note at 128 BPM (60000 / 128 / 4 = 117 ms) - the limiter recovers between kicks instead of pumping across them.
		`Gain (dB)`	2.5	The push. Watch gain reduction: past 4-5 dB on a techno master the groove flattens.

Podcast Voice Master

Master bus for spoken word - podcast, audiobook, narration - delivered in mono.

The decision most tutorials skip: speech is not music. Auto release is switched on so the limiter follows the program instead of pumping in the gaps between sentences, and Utility Width is set to 0 so the file sums to mono before the limiter - many podcast players are mono, and a stereo file that collapses badly loses level exactly where the voice is.

Signal chain: EQ Eight → Saturator → Utility → Limiter

#	Device	Control	Value	What it does
1	EQ Eight	`Band 1 filter type (12 dB low cut)`	1	Removes desk rumble and handling noise; a gentle slope so the voice keeps its chest.
		`Band 1 Freq (Hz)`	80	Below almost every adult speaking fundamental, above the room rumble that a small booth adds.
		`Band 2 Freq (Hz)`	350	The boxy resonance an untreated room puts on a close-miked voice.
		`Band 2 Gain (dB)`	-2.5	Clears the muddiness that makes speech tiring over a 40-minute episode.
		`Band 2 Q`	1.1	Wide enough to treat the room rather than one note of the voice.
		`Band 3 filter type (high shelf)`	5	Even presence lift instead of a peak that would sharpen esses.
		`Band 3 Freq (Hz)`	4500	The intelligibility region: consonants, not sibilance.
		`Band 3 Gain (dB)`	2.0	Speech tolerates more presence lift than music; if it starts to hiss, pull this to 1 dB first.
2	Saturator	`Drive (dB)`	3.0	Adds harmonics so a thin voice reads on a phone speaker without raising the level.
		`Dry/Wet`	0.25	Low blend - speech shows distortion far sooner than music does.
3	Utility	`Width (mono)`	0	Sums to mono before the limiter, so what you hear is exactly what a mono podcast player will play - no surprise cancellation.
		`Gain (dB)`	1.0	Recovers the level the mono sum can cost.
4	Limiter	`Ceiling (dB)`	-1.0	Sample-peak limiter: 1 dB left for the inter-sample peaks that appear after the episode is encoded to MP3/AAC.
		`Auto release (on)`	True	Release follows the program, so the limiter does not breathe in the silence between sentences the way a fixed release does.
		`Gain (dB)`	3.0	Speech is quiet at the source; push here until your meter hits the loudness your host asks for.

Acoustic Dynamic Master

Master bus for acoustic, folk, singer-songwriter and classical-leaning material where dynamics are the point.

The decision most tutorials skip: on acoustic material the mastering job is not loudness. Drive is 1.5 dB at 15% wet and the limiter is set to catch peaks, not to squash - keep gain reduction under about 2 dB and streaming normalisation will turn this up for you anyway, without the flattening a loud master brings.

Signal chain: EQ Eight → Saturator → Limiter

#	Device	Control	Value	What it does
1	EQ Eight	`Band 1 filter type (12 dB low cut)`	1	The gentlest available slope - acoustic low end is mostly real instrument body, not rumble.
		`Band 1 Freq (Hz)`	40	Below an upright bass and a low piano note; removes only stage and floor rumble.
		`Band 2 Freq (Hz)`	500	Where guitar body and vocal low mids overlap on a close-miked recording.
		`Band 2 Gain (dB)`	-1.0	1 dB - the smallest move that still opens the mix; anything bigger belongs in the mix, not here.
		`Band 2 Q`	0.9	Very wide, so it reads as a tonal tilt rather than as EQ.
		`Band 3 filter type (high shelf)`	5	Air across the whole top rather than a bright spot.
		`Band 3 Freq (Hz)`	12000	Pure air region - above strings and bow noise.
		`Band 3 Gain (dB)`	1.5	Opens the room sound of an acoustic recording without touching the instrument's character.
2	Saturator	`Drive (dB)`	1.5	Just enough harmonic glue to sound finished; acoustic sources expose saturation immediately.
		`Dry/Wet`	0.15	15% - you should only notice it when you bypass it.
3	Limiter	`Ceiling (dB)`	-1.0	Same headroom rule: Live's Limiter reads sample peaks, so 1 dB covers what encoding adds back.
		`Release (ms)`	250	Slow, so the few peaks it catches are let go smoothly instead of modulating a sustained piano or string note.
		`Gain (dB)`	0.5	Deliberately small. If you need more than 2 dB of gain reduction on this material, the mix is the place to fix it.

Mono Bass Check

A listening check, not a processor: sums to mono and plays only the low end so phase cancellation is audible. Switch it off before you export.

The decision most tutorials skip: bass that disappears in mono is the single most common reason a master sounds thin on a club system, a phone speaker or a laptop. This rack sums to mono and cuts everything above 300 Hz so you hear the low end alone - if it loses weight when you enable this rack, a stereo widener or a wide sub-bass patch in your mix is cancelling. Fix it in the mix, then bypass or delete this rack; it must not be in the chain when you render.

Signal chain: Utility → EQ Eight

#	Device	Control	Value	What it does
1	Utility	`Width (mono)`	0	Collapses left and right to mono - exactly what a club PA subwoofer and most phone speakers do.
2	EQ Eight	`Band 1 filter type (48 dB high cut)`	7	A steep cut so nothing above the bass region leaks in and hides the cancellation.
		`Band 1 Freq (Hz)`	300	Keeps kick, bass and their first harmonics; removes everything that would distract from the question being asked.
		`Band 2 (off)`	False	Every other band is left out of the way so this rack only ever does one thing.
