Die golfvorm wys die insetvlak en help met volumebeheer.

Because die is the Afrikaans definite article, equivalent to English the.

In this sentence:

• die golfvorm = the waveform
• die insetvlak = the input level

Afrikaans uses die for:

• singular nouns
• plural nouns
• all genders

So unlike languages such as German or Dutch, you do not change the article based on gender. It is simply die in all these cases.

Yes, golfvorm is correctly written as one word. Afrikaans often forms compound nouns by joining words together, much like German and often more consistently than English.

Here:

• golf = wave
• vorm = form/shape

So golfvorm literally means waveform.

This is very common in Afrikaans:

• insetvlak = input level
• volumebeheer = volume control

If you are an English speaker, it helps to expect Afrikaans technical terms to be written as single compounds more often than in English.

Wys means shows here.

Afrikaans verbs are much simpler than English verbs in the present tense. They usually do not change depending on the subject.

For example:

• Ek wys = I show
• Jy wys = you show
• Die golfvorm wys = the waveform shows

So Afrikaans does not do the English-style change from show to shows for third-person singular. The verb just stays wys.

Insetvlak is another compound noun:

• inset = input
• vlak = level

So insetvlak means input level.

This is a good example of how Afrikaans often builds technical vocabulary by combining simple words into one longer noun. If you can spot the parts, these compounds become much easier to understand.

Because help met means help with something.

In this sentence:

• help met volumebeheer = helps with volume control

Here, volumebeheer is a noun, so met is the natural choice.

Compare:

• help met volumebeheer = help with volume control
• help om die volume te beheer = help to control the volume

Both are possible structures, but they mean slightly different things:

• help met + noun focuses on assistance with a thing or process
• help om ... te + verb focuses on helping to do an action

Because volumebeheer is being used as a general, abstract concept: volume control.

Afrikaans often leaves out the article when talking about something in a general way, especially with abstract or technical nouns.

So:

• help met volumebeheer = help with volume control

If you added an article, it would sound more like you were referring to a specific instance or specific control system, depending on context. Here, the general idea is meant, so no article is needed.

The structure is:

• Die golfvorm = subject
• wys = first verb
• die insetvlak = object
• en help = second coordinated verb
• met volumebeheer = prepositional phrase

So literally:

• The waveform shows the input level and helps with volume control

Afrikaans allows the same subject to apply to both verbs:

• Die golfvorm wys ... en help ...

You do not need to repeat the subject:

• not necessary: Die golfvorm wys ... en die golfvorm help ...

That would be grammatical, but less natural unless you want emphasis.

Here en means and, and it links two actions performed by the same subject.

The subject die golfvorm applies to both verbs:

• wys
• help

So it is basically:

• The waveform shows the input level and helps with volume control

You can think of it as one subject with two coordinated verbs. This is very normal in Afrikaans and works much like English.

A rough English-friendly guide:

• golfvorm ≈ KHOLF-form
  
  • The g is the guttural Afrikaans sound, not the English g.
• wys ≈ vace or vays depending on accent and how roughly you approximate it
  
  • The w in Afrikaans sounds like English v.
• volumebeheer ≈ vo-lu-meh-beh-HEER
  
  • The h is pronounced.
  • beheer has stress near the end.

A few key pronunciation points:

• Afrikaans w is usually like English v
• Afrikaans g is usually a throaty sound, not a hard English g
• y in wys is not like English y in yes

Yes, often you could use toon as well.

• wys = show
• toon = show/display

In many contexts they overlap. However, wys is extremely common and natural in everyday Afrikaans. In technical contexts, both may appear, but wys often sounds very straightforward and idiomatic.

So:

• Die golfvorm wys die insetvlak is perfectly natural.
• Die golfvorm toon die insetvlak could also work, depending on style and context.

Yes. The sentence is in the present tense.

• wys = shows
• help = helps

Afrikaans present tense is usually very simple:

• no change for person
• no extra ending like English -s for he/she/it

So the sentence describes what the waveform generally does:

• it shows the input level
• it helps with volume control

This kind of present tense is commonly used for instructions, manuals, software descriptions, and technical explanations.
