Саундтрек уже готов.

In Russian, the verb to be is usually omitted in the present tense.

So:

• Саундтрек готов = The soundtrack is ready
• literally: Soundtrack ready

Russian speakers do not normally say a present-tense equivalent of is here.

But in the past or future, forms of to be do appear:

• Саундтрек был готов. = The soundtrack was ready.
• Саундтрек будет готов. = The soundtrack will be ready.

Уже means already.

So:

• Саундтрек готов. = The soundtrack is ready.
• Саундтрек уже готов. = The soundtrack is already ready.

In natural English, you would often translate this simply as:

• The soundtrack is already done.
• The soundtrack is ready now.

Уже adds the idea that the result has been reached by this point, perhaps sooner than expected or in contrast to something else that is not ready yet.

Готов is the short form of the adjective готовый.

Russian has two adjective forms in many cases:

• long form: usually used as a normal descriptive adjective before a noun
• short form: often used in the predicate, especially after an implied is/are

Here, готов is used because it means is ready:

• Саундтрек уже готов. = The soundtrack is already ready.

Compare:

• готовый саундтрек = a ready/finished soundtrack
• саундтрек готов = the soundtrack is ready

This short form is very common with готов.

Because саундтрек is a masculine singular noun.

The short-form adjective has to agree with the noun:

• masculine: готов
• feminine: готова
• neuter: готово
• plural: готовы

Examples:

• Фонограмма уже готова. = The audio track is already ready.
• Письмо уже готово. = The letter is already ready.
• Документы уже готовы. = The documents are already ready.

Since саундтрек is masculine, the correct form is готов.

It is in the nominative case.

In this sentence, саундтрек is the subject:

• Саундтрек = the soundtrack
• уже готов = is already ready

So the basic structure is:

• [subject in nominative] + [adverb] + [short-form adjective]

That is why саундтрек stays in its dictionary form here.

Yes. Russian word order is more flexible than English, although the neutral order here is very natural:

• Саундтрек уже готов.

Other orders are possible, with different emphasis:

• Уже саундтрек готов. — sounds marked; emphasizes already
• Саундтрек готов уже. — possible in context; often sounds more conversational or contrastive
• Готов уже саундтрек. — very marked; poetic or strongly contrastive

For most learners, the safest and most natural version is:

• Саундтрек уже готов.

It can suggest either, depending on context.

Basic meaning:

• готов = ready

But in many real situations, especially with creative work, food, documents, or a project, English may translate it more naturally as:

• finished
• done
• completed

So Саундтрек уже готов could mean:

• The soundtrack is ready.
• The soundtrack is already finished.
• The soundtrack is already done.

The exact English wording depends on context.

Yes. Саундтрек is a borrowed word from English soundtrack, but it is fully used as a Russian noun.

Like many borrowed nouns, it behaves like a normal masculine Russian noun:

• саундтрек
• саундтрека
• саундтреку
• etc.

So even though it comes from English, Russian treats it grammatically like a regular noun.

A helpful approximate pronunciation is:

• SAUND-trek oo-ZHE ga-TOF

A few notes:

• уже is stressed on the second syllable: ужЕ
• готов is stressed on the second syllable: готОв
• the final в in готов is pronounced like f at the end of the word, so it sounds like гатоф

A more careful transliteration:

• Saundtrék uzhé gatóf

Russian has no articles like a or the.

So саундтрек can mean:

• a soundtrack
• the soundtrack

The context tells you which one is meant.

In Саундтрек уже готов, English will usually say the soundtrack if both speakers already know which soundtrack they are talking about.
