Chapter 18 – The Ultimate Manual of Tags, FX and Parameters in Suno 4.5 Pro

Introduction

Mastering Suno 4.5 Pro is not limited to knowing a handful of commands. To produce a professional, punchy sound that resembles you, you have to master the whole palette of tags, FX, commands and parameters available. This exhaustive, detailed guide gives you everything, from the basics to the advanced settings, with examples, scenarios, practical tips, and strategies to integrate your voice and get the best rendering.

This chapter opens the door to a universe where every detail counts, where you perfectly control every sound nuance and every emotion carried by the voice.

SECTION 1 – Vocal tags: The basis of control of your AI voice

1.1 Voice selection tags

Tag	Description	Example	Tips
`<voice name='xxx'>…</voice>`	Choice of an AI or personalized voice	`<voice male='voice_morel_suno'>Hi, it’s me.</voice>`	Preload your personal voice in Suno, name it clearly
`<voice female='voice_alys_suno'>…</voice>`	Specific female voice	`<voice female='voice_alys_suno'>Hello world!</voice>`	Use female voices for contrast or duet
`<voice neutral='default'>…</voice>`	Default neutral voice	`<voice neutral='default'>Classic text.</voice>`	Ideal for narrations or segments without strong emotion

1.2 Expression and emotion tags

Tag	Function	Example	Usage advice
`<emotion value='happy'>…</emotion>`	Makes the voice joyful	`<emotion value='happy'>I’m happy.</emotion>`	Perfect for choruses or optimistic moments
`<emotion value='sad'>…</emotion>`	Gives a sad tone	`<emotion value='sad'>I’m sorry.</emotion>`	Use in ballads or introspective passages
`<emotion value='angry'>…</emotion>`	Accentuates anger or energy	`<emotion value='angry'>Trust me!</emotion>`	For punchlines, aggressive or motivating segments

1.3 Tags for advanced vocal nuances

Tag	Function	Example	Tip
`<breath>`	Inserts a natural breath	I’m tired `<breath>` but ready.	Adds realism and humanizes the voice
`<whisper>`	Makes the passage whispered	`<whisper>This secret is for you.</whisper>`	Perfect for mysterious or intimate passages
`<overlap>`	Overlap of two voices or phrases	`<voice1>Are you coming?</voice1><overlap><voice2>I’m coming!</voice2>`	Useful for dynamic dialogues or crowd atmosphere

SECTION 2 – Voice correction and modulation: autotune, pitch, speed

2.1 Autotune

Autotune corrects the accuracy of the voice, creates a modern effect, or can totally transform the colour of the singing.

Tag	Description	Example	Usage advice
`<autotune XX%>`	Applies an autotune rate of 0 to 100%	`<autotune 40%>Phrase with autotune.</autotune>`	Between 20-40% for natural, 60-90% for trap or modern effect

Scenario

You want a natural but slightly corrected verse, use 25-30%. For a very marked electro or trap chorus, go up to 70-90%.

2.2 Pitch Shift (Change of pitch)

Tag	Function	Example	Tip
`<pitch shift +X>` / `-X`	Shifts the key by X semitones (positive or negative)	`<pitch shift +3>Higher voice</pitch shift>`	Used for harmonies, doubling effects, or transitions

2.3 Formant Shift (Change of timbre)

Tag	Function	Example	Tip
`<formant shift +X>` / `-X`	Changes the timbre without touching the pitch	`<formant shift -1>Deeper voice</formant shift>`	Creates robotic or caricatural effects

2.4 Speed

Tag	Description	Example	Advice
`<speed XX%>`	Changes the pronunciation speed (e.g.: 120%)	`<speed 150%>Accelerated phrase</speed>`	Accelerates for dynamic effect or slows down for emotion

SECTION 3 – Sound effects (FX): reverb, delay, chorus, phaser, distortion

3.1 Reverb

Tag	Description	Example	Practical use
`<reverb type='soft/long/hall'>…</reverb>`	Soft, long reverb, concert hall	`<reverb type='hall'>Voice in a hall</reverb>`	Creates space and depth according to the chosen type

3.2 Delay

Tag	Function	Example	Tip
`<delay ms=X>`	Applies a delay of X milliseconds	`<delay ms=300>Phrase with echo</delay>`	To create a subtle or marked echo effect

3.3 Echo

Tag	Description	Example	Tip
`<echo delay=XXX ms>`	Echo effect with precise delay	`<echo delay=400ms>Phrase in echo</echo>`	Reinforces the sensation of space or intensity

3.4 Chorus

Tag	Function	Example	Tip
`<chorus depth=X rate=X>`	Choir effect with depth and rate	`<chorus depth=0.6 rate=1.2>Choir effect</chorus>`	To thicken or give a “multivoice” effect

3.5 Phaser

Tag	Function	Example	Use
`<phaser rate=X depth=X>`	Phase modulation for psychedelic effect	`<phaser rate=1 depth=0.7>Psychedelic effect</phaser>`	For atmospheric or electronic passages

3.6 Distortion

Tag	Function	Example	Use
`<distortion amount=X>`	Applies saturation/distortion	`<distortion amount=0.3>Saturated voice</distortion>`	For rock, electro or aggressive styles

3.7 Compression

Tag	Function	Example	Use
`<compressor threshold=X ratio=X>`	Dynamic compression of the signal	`<compressor threshold=-20 ratio=3>Compression</compressor>`	Homogenizes vocal level and avoids saturation

SECTION 4 – Spatialization: Panning, 3D audio, Doppler

4.1 Stereo panning

Tag	Description	Example	Tip
`<pan left=X right=Y>`	Places the sound between left (0) and right (1)	`<pan left=0.8 right=0.2>Voice on the left</pan>`	To create space and depth in the mix

4.2 3D audio

Tag	Function	Example	Usage
`<3d audio pan=X>`	Positions the sound in a 3D space (0-1)	`<3d audio pan=0.7>Spatialized voice</3d audio>`	For immersion and sound realism

4.3 Doppler effect

Tag	Description	Example	Use
`<doppler effect speed=X>`	Simulates the Doppler effect (tonal change with movement)	`<doppler effect speed=15>Vehicle effect</doppler>`	To simulate movements or speed effects

SECTION 5 – Mixing and volume control: EQ, fade, loop, silence

5.1 Equalizer (EQ)

Tag	Function	Example	Tip
`<eq low=X mid=X high=X>`	Adjusts bass, mids and highs	`<eq low=4 mid=-2 high=0>Adjusted EQ</eq>`	To sculpt the voice and make it stand out
