Getting the sample rate for an externalData object?

[Orvillain]

Is it possible to get the sample rate for an externalData object?

We can do the following:

	void setExternalData(const ExternalData& data, int index)
	{
		if (data.isNotEmpty())
		{
			auto buffer = data.toAudioSampleBuffer();
			float sampleRate = 44100.0f; // Replace with actual rate if available

			// down sampling and other pre-processing stages go here

			hise::JSONObject obj;
			obj[String("length")] = buffer.getNumSamples();
			obj[String("RMS")] = buffer.getRMSLevel(0, 0, buffer.getNumSamples());
			obj[String("knobValue")] = value;

			this->sendDataToGlobalCable<GlobalCables::dataCable>(obj);
		}
	}

But there does not seem to be a way to get the sample rate for either the data object or the buffer itself.

I'm writing a node that makes a copy of an audio buffer and downsamples it, but I would really like to track the sample-rate of the original file, so I can calculate the sample-rate of my downsampled audio.

@Orvillain data.sampleRate should be populated with the file samplerate if the audio buffer comes from an external file.

Dohhhh. I was trying data.getSampleRate() - my mistake!

Is there anywhere where that sort of thing is documented Chris? If not, where should it be? I can get the ball rolling.

@Christoph-Hart haha, My Funky summary, lol that autogenerator has gone crazy...

Cool thanks! I'm still figuring out how all of this interfaces, but getting there and making good progress!
