Starting with Loris Library (createEnvelopePaths)

[fazzitog]

Hi folks, I'm starting with the Loris library. The starting idea is to morph the timbre from sound 1 with the timbre of sound 2. But the problem comes with the EnvelopePaths:
LorisManager.createEnvelopePaths(var file, String parameter, int harmonicIndex)

As I can't get it to work. Do know what I'm doping wrong?

The code si the following

var file_1 = FileSystem.getFolder(FileSystem.AudioFiles).getChildFile("deep_piano_noise.wav"); 
var file_2 = FileSystem.getFolder(FileSystem.AudioFiles).getChildFile("SonidoVoz.wav");

const var lorisManager = Engine.getLorisManager();

const sampleRate = Engine.getSampleRate();
var bitDepth = 24;

lorisManager.set("timedomain", "0to1");
lorisManager.set("enablecache", "False");

var analysis_file_1 = lorisManager.analyse(file_1, 40);

var frequencyEnvelope = lorisManager.createEnvelopePaths(file_1, "frequency", -1); // Use -1 for all harmonics

// Step 2: Use the frequency envelope from file_1 to shift the pitch of file_2
lorisManager.analyse(file_2, 40); // Analyze file_2 first

lorisManager.process(file_2, "shiftPitch", frequencyEnvelope);



var modifiedBuffer = lorisManager.synthesise(file_2);


// Export audio
FileSystem.getFolder(FileSystem.Desktop).getChildFile("ChangedAudio.wav").writeAudioFile(modifiedBuffer, 44100, 24); // Save as a file

Here's the full snipped if anyone want to check:
