Where the most dominating modes are located and what the average energy level is.Average of All Spectral DensitiesThese functions can be identified in the Data Organizer by their short name The average of all spectral densities provides a fast indication of where the most dominating modes are located and what the average energy level is.Short Time Fourier Transform - STFT (Spectrogram)The x-axis presents the frequencies between DC and the Nyquist frequency, The y-axis presents the measurement time. Red colors indicates the regions with most energy and dark bluThe x-axis presents the frequencies between DC and the Nyquist frequency, The y-axis presents the measurement time. Red colors indicates the regions with most energy and dark blue the regions with smallest energy level.The average of the spectrogram (the squared STFT) in the time direction is called the frequency marginal. For some time-frequency distributions the frequency marginal actually equals the power spectrum (and the time marginal equals the signal squared), but this is not the case for the spectrogram, partly because of the positivity, and partly because of the inherent low pass filtering of the windowing used in creating the spectrogram. However, the frequency marginal resembles the power spectrum. Here the Power Spectral Density (PSD) is estimated using the Welch method, which is quite similar to the frequency marginal. To make the spectrogram similar in magnitude to the PSD, such as to enable a direct comparison between the two energy representations, the spectrogram has been modified so that the time-averaged value at any given frequency in the spectrogram has the same magnitude as the PSD for that frequency. Since the PSD is an estimated density where frequency resolution has been traded for better signal to noise ratio the same applies to the scaled spectrogram.Average Kurtosis of All Projection Channels Estimated at Individual FrequenciesIf there are spikes in more than one line in the Singular Value Decomposition diagram they most likely have their origin due to an harmonic excitation. These harmonics disturb the mode estimation and therefore it is preferable to detect and remove these harmonics from the mode estimation. To detect these harmonics you have to enable the harmonic detection in the Signal Processing window. When enabled and the measurements have been processed you are ready to detect the harmonics. After processing you can view the detected harmonics in all frequency domain windows by checking the Show Harmonic Indicators check box which can be found in the Properties window.The consequences of having harmonic components present in the responses depend on both the nature of the harmonic components (number, frequency and level) and the modal parameter extraction method used. For the EFDD and CFDD techniques it is important that harmonic components inside the desired SDOF are identified and their influence eliminated before proceeding with the modal parameter extraction process. It shouldbe noticed that harmonic components cannot, in general, be removed by simple filtering as this would in most practical cases significantly change the poles of the structural modes and thereby their natural frequency and.

Spectrograms - definition of spectrograms by The Free Dictionary

(yes, no, up, down, etc) for an audio file.def get_label(file_path): parts = tf.strings.split(file_path, os.path.sep) return parts[-2]Next, we need to associate the audio files with the correct labels. We're doing this and returning a tuple that Tensorflow can work with:# Create a tuple that has the labeled audio filesdef get_waveform_and_label(file_path): label = get_label(file_path) audio_binary = tf.io.read_file(file_path) waveform = decode_audio(audio_binary) return waveform, labelWe briefly mentioned using the convolutional neural network (CNN) algorithm earlier. This is one of the ways we can handle a voice recognition model like this is. Typically CNNs work really well on image data and help decrease pre-processing time.We're going to take advantage of that by converting our audio files into spectrograms. A spectrogram is an image of a spectrum of frequencies. If you take a look at an audio file, you'll see it's just frequency data. So we're going to write a function that converts our audio data into images:# Convert audio files to imagesdef get_spectrogram(waveform): # Padding for files with less than 16000 samples zero_padding = tf.zeros([16000] - tf.shape(waveform), dtype=tf.float32) # Concatenate audio with padding so that all audio clips will be of the same length waveform = tf.cast(waveform, tf.float32) equal_length = tf.concat([waveform, zero_padding], 0) spectrogram = tf.signal.stft( equal_length, frame_length=255, frame_step=128) spectrogram = tf.abs(spectrogram) return spectrogramNow that we have formatted our data as images, we need to apply the correct labels to those images. This is similar to what we did for the original audio files:# Label the images created from the audio files and return a tupledef get_spectrogram_and_label_id(audio, label): spectrogram = get_spectrogram(audio) spectrogram = tf.expand_dims(spectrogram, -1) label_id = tf.argmax(label == commands) return spectrogram, label_idThe last helper function we need is the one that will handle all of the above operations for any set of audio files we pass it:# Preprocess any audio filesdef preprocess_dataset(files, autotune, commands): # Creates the dataset files_ds = tf.data.Dataset.from_tensor_slices(files) # Matches audio files with correct labels output_ds = files_ds.map(get_waveform_and_label, num_parallel_calls=autotune) # Matches audio file images to the correct labels output_ds = output_ds.map( get_spectrogram_and_label_id, num_parallel_calls=autotune) return output_dsNow that we have all of these helper functions, we get to split the data.Splitting the Data into DatasetsConverting audio files to images helps make the data easier to process with a CNN and that's why we wrote all of those helper functions. We'll do a couple of things to make splitting the data more simple.First, we'll get a list of all of the potential commands for
