Suno V4 Core Functional Depth Resolution

Remaster

Old Remaster Remaser function

You can resamp with the valuable work you used to produce with V3 or V3.5, using a powerful V4 model. It would retain melody structures but greatly enhance the purity and quality of the audio and address the problem of the high-noise and high-frequency deficiencies of the old version.

Covers

Reverse Evolution: Covers function

Uploading your own humming or an existing audio clip, Suno V4 can remake it into a whole new style. Like turning a singing into a symphony rock or turning a slow song into a moving EDM.

Length

Full expression: 4 minutes long song

Original support produces a full four-minute track, consisting of a full lead, a side song, a bridge section and a weak ending, without frequent clicks on the Extend puzzle.

Professional Prompt Techniques (Advanced Tagging)

In Custom mode, the use of square brackets labels [Meta-tags] can greatly control the generation effect:

Structure control: [Intro], [Verse], [Pre-Chorus], [Chorus], [Bridge], [Outro]
Instrumental command: [Guitar Solo], [Piano Drop], [Heavy Bassline], [Synthesizer Breakdown]
♪ Singing style: [Whispered], [Belting], [Staccato], [Emotional crescendo]
Dynamic adjustments: [Build up], [Sudden stop], [Acoustic break]

Common issues (FAQ)

Who's the resulting song copyright?

If you are a pay subscriber (Pro or Premier), you have full commercial copyrights for the resulting songs, which can be uploaded to platforms like Spotify, Apple Music. Free users have only non-commercial access.

How does AI sing a particular dialect or accent?

Insert [Cantonese], [Hokkien] or [Sicuan Dialect] labels in the Stile of Music. Not 100% accurate, but with the correct tone of the lyrics, the effects are often surprising.

What if we run out of points?

Paying users can purchase additional subcontracts on the subscription page. The subcontracts are permanently valid and will not be eliminated with the monthly plan.

What's the use of Personas?

Personas allows you to "lock" the sound that you generate at one time. You've created a great song, so you can save this to Persona if you want to sing another song from the same voice.
