I'm intending to add white noise to a simple periodic signal

```
p = TransformedProcess[
Cos[t/8] + noise[t],
noise \[Distributed] WhiteNoiseProcess[],
t];
```

Adding it at integer intervals is fine

```
data = RandomFunction[p, {0, 10}]
```

yields a TemporalData value as expected

But

```
data = RandomFunction[p, {0, 10, 0.1}]
```

causes an error

"The specification WhiteNoiseProcess[NormalDistribution[0,1]] is not a random process recognized by the system"

Am I at fault or is it a bug?

thanks, that with https://reference.wolfram.com/language/ref/TimeSeriesRescale.html will meet my needs. Just makes me ponder about the real nature of white noise. Is there a better solution to modelling acoustic noise than white noise? The time series Iām modelling in the end being an acoustic one.
