Bulk Convert SampleMaps to WaveTables

A Former User

After individually converting about 30 of them, could we pretty please possibly get an option to loop the conversion for all the SampleMaps in the folder using the same settings?

I'd do it myself but there's a 90% chance I end up breaking both HISE and the OS of my computer :)

Christoph Hart

@iamlamprey But it's a 10% chance that you succeed so go for it! :)

d.healey

Make it command line accessible and then you can just write a script to do it :p

Well I made the button show up... thinking about writing a book on advanced C++

Okay so I know I need to add this:

else if (name == "BulkConvert")
		{
			for (int i = 0; i < list.size; i++)
			{
				
			}
		}

To the button function, and I assume I need to make sure list is visible to it, but I have no idea where to start with iterating through, since it relies on the currently loaded/selected samplemap of the combobox...

This next part is from a different function so I assume I can't access the result of it

void comboBoxChanged(ComboBox* comboBoxThatHasChanged) override
	{
		if (getComboBoxComponent("samplemap") == comboBoxThatHasChanged)
		{
			auto& spool = chain->getMainController()->getActiveFileHandler()->pool->getSampleMapPool();

			PoolReference ref(chain->getMainController(), comboBoxThatHasChanged->getText(), FileHandlerBase::SampleMaps);

			currentlyLoadedMap = ref.getFile().getFileNameWithoutExtension();

@d-healey Is this a thing on windows? I'd rather tinker with C++ but it could be an option if I cant figure it out

d.healey

@iamlamprey Yes, but you'd still need to tinker with C++ to add the functionality to the CLI.

A Former User

Yeh idk the amount of time it would take me to get it is likely going to be much larger than individually converting the wavetables

d.healey

@iamlamprey Many a time I've spent a day or more trying to add something in C++ - depends on how badly you want it :)

You'll need to use something like this to loop through all of the sample maps. Then pass the sample map file to the convert to wavetable function. Doesn't look like it should be too complicated actually, but no idea until it's tried.

d.healey

Ok so this is a guess (I've done no testing). You would call this function from your Bulk Convert button's callback.

	void bulkConvertSampleMapsToWavetables()
	{
		auto& spool = chain->getMainController()->getActiveFileHandler()->pool->getSampleMapPool();
		
		for (int i = 0; i < list.size; i++)
		{
			PoolReference ref(chain->getMainController(), list[i], FileHandlerBase::SampleMaps);
			currentlyLoadedMap = ref.getFile().getFileNameWithoutExtension();
			
			if (auto vData = spool.loadFromReference(ref, PoolHelpers::LoadAndCacheWeak))
			{
				converter->parseSampleMap(*vData.getData());

				if (currentMode == FFTResynthesis)
				{
					converter->refreshCurrentWavetable(getProgressCounter());
					
				}
				
				refreshPreview(); 
			}
		}	
	}

@d-healey Insane. I wasn't anywhere close to that lmao

I'll try and build it tomorrow, officially past my bed time in aus :)

@iamlamprey For a smooth interpolation between the waves, is there any limit of the wave numbers? I remember that you said that you are getting artifacts for this?

Christoph Hart

@orange if you enable hq mode, it already interpolates between the tables.

Great to know that. Thanks!

Okay using @d-healey 's script as a starting point, I can get it looping through the sampleMaps and everything, but it's currently not "clearing" the file each time it iterates, so the wavetables get larger and larger (and i assume sound terrible)

I also got rid of the right side since it doesn't work anyway:

void bulkConvertSampleMapsToWavetables()
	{
		auto& spool = chain->getMainController()->getActiveFileHandler()->pool->getSampleMapPool();
		auto& list = chain->getMainController()->getActiveFileHandler()->pool->getSampleMapPool().getIdList();

		for (int i = 0; i < list.size(); i++)
		{
			currentlyLoadedMap = "";

			PoolReference ref(chain->getMainController(), list[i], FileHandlerBase::SampleMaps);
			currentlyLoadedMap = ref.getFile().getFileNameWithoutExtension();

			if (currentMode == FFTResynthesis)
				converter->renderAllWavetablesFromHarmonicMaps(getProgressCounter());
			else
				converter->renderAllWavetablesFromSingleWavetables(getProgressCounter());

			if (threadShouldExit())
				return;

			auto leftTree = converter->getValueTree(true);

			auto fileL = currentlyLoadedMap + "_Left.hwt";

			auto tfl = GET_PROJECT_HANDLER(chain).getSubDirectory(ProjectHandler::SubDirectories::AudioFiles).getChildFile(fileL);

			PresetHandler::writeValueTreeAsFile(leftTree, tfl.getFullPathName());
		}
	}

I can't see any reason why it wouldn't clear the samplemap each time, I even added an empty string at the start of the loop to clear it but idk

d.healey

@iamlamprey I assume the renderAllWaveTables... functions are doing something to all the wavetables in the folder and creating a new wavetable, then when it loops again there are two wavetables being processed, then 3, then 4, etc.

I don't think it has anything to do with currentLoadedMap.

A Former User

@d-healey Yeah so close now, I moved it out of the for loop which solved the size problem, but now all of the wavetables are the same

So i think it has to do with making renderAllWaveTables reset each time or something

d.healey

@iamlamprey What does renderAllWaveTables do?

A Former User

@d-healey i think it's the actual conversion part, the rest is just writing the result to a file

void SampleMapToWavetableConverter::renderAllWavetablesFromSingleWavetables(double& progress)
{
	using Data = ResynthesisHelpers::SimpleNoteConversionData;

	for (int i = 0; i < 128; i++)
	{
		Array<Data> conversionData;

		for (auto s : sampleMap)
		{
			int loKey = s.getProperty(SampleIds::LoKey, -1);
			int hiKey = s.getProperty(SampleIds::HiKey, -1);
			int root = s.getProperty(SampleIds::Root, -1);

			if (i >= loKey && i <= hiKey)
			{
				auto thisFreq = MidiMessage::getMidiNoteInHertz(i);
				auto rootFreq = MidiMessage::getMidiNoteInHertz(root);


				auto fName = s.getProperty(SampleIds::FileName).toString();

				if (fName.isEmpty())
					s.getChild(0).getProperty(SampleIds::FileName).toString();

				PoolReference r(chain->getMainController(), fName, FileHandlerBase::Samples);

				Data data;
				data.sampleFile = r.getFile();
				data.rootRatio = thisFreq / rootFreq;
				data.noteNumber = i;
				data.veloRange.setStart((int)s.getProperty(SampleIds::LoVel, 0));
				data.veloRange.setEnd((int)s.getProperty(SampleIds::HiVel, 127) + 1);

				conversionData.insert(-1, data);
			}
		}

		progress = (double)i / 128.0;

		if (conversionData.isEmpty())
			continue;

		struct DataSorter
		{
			int compareElements(Data& first, Data& second)
			{
				if (first.veloRange.getStart() < second.veloRange.getStart())
					return -1;

				if (first.veloRange.getStart() > second.veloRange.getStart())
					return 1;

				return 0;
			}
		};

		DataSorter sorter;

		conversionData.sort(sorter);


		auto output = ResynthesisHelpers::loadAndResampleAudioFilesForVelocity(conversionData, sampleRate);

		storeData(i, output.getWritePointer(0), leftValueTree, output.getNumSamples(), conversionData.size());

		if (output.getNumChannels() == 2)
		{
			storeData(i, output.getWritePointer(1), rightValueTree, output.getNumSamples(), conversionData.size());
		}
	}
}

@iamlamprey I think you might need to wait for some Christoph input

@d-healey all good, ill keep noodling in the meantime :) cheers
