Hello Team, I am trying to generate a spectrogram with the Multicolored with the Magnitude and Frequencies of audio. But using this code I could able to only generate a mono-color spectrogram as shown in the below Image.  And Is there any way to generate a Multi-colored spectrogram like the one which I have shared below.  Below I have attached the source code of it, kindly check it and tell me If there is anything needs to update. Thanks in advance! ``` private func getSpectrogramImageGenerationFromMicrophoneAudio(recordedURL : URL) { let acqCtx = AcquisitionContext(fftSize: 1024, sampleRate: 44100) acqCtx.frequencyStepForIndex(1) let rawAudio = DataLoader.loadAudioSamplesArrayOf(Float.self, atUrl: recordedURL, sampleRate: 44100, channels: 1) if rawAudio == nil { return } let signalAudio = rawAudio!.chunks(acqCtx.fftSize) let fftValues = signalAudio.map{ fft($0) } let realValues = fftValues.map{ Array($0.real[0..<$0.real.count/2]) } for i in 0..<acqCtx.fftSize { acqCtx.frequencyStepForIndex(i) } let magnitudes = spectrogramValuesForSignal(input: rawAudio!, chunkSize: 512) let image3 = ImageUtils.drawImageForMagnitudes1(magsArray: magnitudes) DispatchQueue.main.async { let spectrogramImage = image3?.flipped let spectrogramImageJpeg = spectrogramImage?.jpegData(compressionQuality: 0) print(spectrogramImageJpeg) self.imgVwSpectrogram.image = spectrogramImage } } ```
