Perhaps Mix would be a better name. Audio streams are joined here, not compared.

Why not use a float64 pointer directly? It doesn't look like this new type is needed.

No need for a private setter that is used only once.

It's easier to use Ginkgo's BeforeEach callbacks for setup IMO

Should be mixer_test. Don't include tests in the same package.

Mixer does not allow this private field to be set by other packages. Tests shouldn't do it either.
This is another reason why it's better to put tests in a separate _test package.

This looks more like an example than a test since we have to check the file manually.
Maybe it should use a real compressor and be in ./examples.
Here should be a simple test with bare values like in Compressor.

There should be an initialization func:
func NewMixer(compressor compressor.Compressor) *Mixer {
return &Mixer{audioCompressor: compressor}
}

In Go interfaces are usually defined in user packages. So Mixer should define what it accepts as a Compressor.

It's convenient to use a struct instead of obscure parameter lists:
compressor.NewDynamicRangeCompressor(compressor.Options{
Threshold: 0.8,
CompressionRatio: 0.8,
Attack: 200,
Release: 1000,
})

Can attackTimer be set here as well?

Looks like it's possible to do this without thresholHasBeenExceeded:
decrease attackTimer until it's zero,
then if attackTimer == 0 decrease releaseTimer (and apply compressFunction) until it's zero
