Grom Zvuk

Q: Why is there no streaming, no way to hear part of it earlier?

Grom Zvuk works on every part of the track at once — intro, verses, chorus and ending are computed as one composition. That is why no partial result exists: the track appears when it is complete. In exchange the parts never argue with each other and the mix is consistent across the full length.

Q: Which languages does it sing in?

Any of them — from English to Chinese and Japanese. The model reads the lyrics, the stress and the phrasing of the language, so the vocal sounds natural rather than accented.

Q: How do I make a cover?

Upload the source track and describe the style it should be sung in. The model keeps the melody and the lyrics, and picks the arrangement, instruments and vocal delivery to match the new genre.

Q: Can I get an instrumental only?

Yes. Say in the prompt that no vocals are needed and the model returns an instrumental version at the tempo and mood you asked for.

Q: Is the model available over API?

Yes — with the same GPTunneL key as every other model: create a task, wait for the finished track, collect the mp3.

Q: Who owns the rights to the track?

The result of a generation stays yours. For covers of someone else's songs, remember the rights to the original composition — those are governed by copyright law, not by the service.

Technology

How a track is made

First the model floods the whole length of the future song with noise and marks out where the verses go, where the chorus lands and where the bridge sits. Then, over several passes, it turns that noise into sound worth listening to.

There is no partial result: the track arrives whole, once it is finished.

Architecture

How the pipeline works

Two experts under shared attention: the first writes music as symbols, the second unfolds those symbols into sound.

Comparison

Where Grom Zvuk sits among music models

Two axes at once: how the track sounds and how closely the model sings the given lyrics. On lyric accuracy Grom Zvuk is in the top three; on sound it holds its place among the closed services.

Under the hood

What sits behind a generation

48 kHz, stereo

Not a compressed draft but a studio sample rate and a real stereo image.

Tracks up to five minutes

A full song with verses, choruses and an ending, not a fifteen-second loop.

A single pass

Every part of the song is computed together rather than in turn — hence the unified sound.

Our own hardware

The model runs on our own fleet of accelerators — we scale capacity to the client's volumes.

Languages

Sings in any language

From English to Chinese and Japanese. The model reads the lyrics, the stress and the phrasing — the vocal never turns into accented mush.

The list is open-ended: these are not all the languages the model sings in.

What it does

Six ways to get a track

The idea of a track lives in the score, so a song can be edited in parts: swap the style, an instrument or the voice without rewriting it.

From scratch

Describe the style and the mood, hand over your lines — the model writes the melody, builds the arrangement and sings it.

Cover

Upload a song and name a new sound: the melody stays recognisable, the arrangement changes completely.

Your own lyrics

Upload a finished song and drop in your own lines: the music stays recognisable, the words are yours.

Style swap

Same track, same lyrics, different genre: a ballad turns into punk, hip-hop into jazz.

Vocals off

Ask for a cover with no lyrics and leave the style empty — the same arrangement remains, just without the voice.

Instrumental

Ambient, lo-fi, a theme for a video — music without words from scratch, from a single description.
