After searching online, I realized that I was most interested in using an audio file <em>as<\/em> as dataset instead of analyzing data about music. I chose a recent release by one of my favorite artists: &#8220;rain&#8221; by mxmtoon. I downloaded an mp3 from the official Youtube visualizer for the song (see below).<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"mxmtoon - rain (official visualizer)\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/6OXSWnEJRmk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Once I had the mp3 file, I needed to figure out what aspects of the audio I wanted to analyze. I wanted to represent the melody and volume of the music, and I found the Librosa Python library  which has a lot of feature analysis for audio. For the melody, I used Librosa&#8217;s pyin feature to find the different pitch frequencies (Fig 1). For the volume, the rms or root-mean-square feature calculated the amplitude of the audio for each time step (Fig 2). As for the third aspect of the data, the chroma features caught my eye. I didn&#8217;t know what chroma was at first, but I found that it is used to represent chords and harmonic progressions in music based on the intensity of each pitch class at that point in the audio. I utilized the Short-time Fourier transform (STFT) version in order to create a 3D Plot (see Fig 3).<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"571\" height=\"455\" src=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Pitches-Fig-1.png\" alt=\"\" class=\"wp-image-13158\" srcset=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Pitches-Fig-1.png 571w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Pitches-Fig-1-300x239.png 300w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Pitches-Fig-1-380x303.png 380w\" sizes=\"auto, (max-width: 571px) 100vw, 571px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Figure 1. The originally detected pitches along with the smoothed version<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The original melody seemed quite noisy, so I first downsampled the data to reduce its amount. Then, I used a Gaussian filter to smooth out the curves. Although this obstructs some of the understanding of the melody in the figure, it allowed for better printing, and the sense of changes in pitches was still translated. <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"567\" height=\"455\" src=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/RMS-Fig-2.png\" alt=\"\" class=\"wp-image-13159\" srcset=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/RMS-Fig-2.png 567w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/RMS-Fig-2-300x241.png 300w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/RMS-Fig-2-380x305.png 380w\" sizes=\"auto, (max-width: 567px) 100vw, 567px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Figure 2.

This successfully reduced the data to an amount that Rhino could handle while preserving the general trends of the volume in the song.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"403\" data-id=\"13154\" src=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface-1024x403.png\" alt=\"\" class=\"wp-image-13154\" srcset=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface-1024x403.png 1024w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface-300x118.png 300w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface-768x302.png 768w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface-1140x448.png 1140w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface-920x362.png 920w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface-575x226.png 575w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface-380x149.png 380w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/chroma-surface.png 1144w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"892\" height=\"590\" data-id=\"13153\" src=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Chroma-Fig.png\" alt=\"\" class=\"wp-image-13153\" srcset=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Chroma-Fig.png 892w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Chroma-Fig-300x198.png 300w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Chroma-Fig-768x508.png 768w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Chroma-Fig-575x380.png 575w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Chroma-Fig-380x251.png 380w\" sizes=\"auto, (max-width: 892px) 100vw, 892px\" \/><\/figure>\n<\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Figure 3a. Left: 3D Surface plot generated from the aggregated chromagram.<br>Figure 3b. Right: Original Chromagram from Librosa on top and Aggregated Chromagram on bottom.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, the chromagram presented the most complicated dataset, but it was the easiest to generate into a plot. Once again, I reduced the amount of data by aggregating based on moving averages.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Data Process<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">I started with the volume data. Because it was a 2D set of data, I wanted to use Revolve Surface to create an interesting form. After an initial attempt, I realized it looked like a vinyl record which I thought connected to my music theme quite nicely. I needed to scale the data, so I added some scaling parameters in the Grasshopper code. I ended up choosing parameters based on what looked most like the record shape I was hoping for. When it printed, I found that the amount the volume varied throughout the song was not all that significant, but it was neat to be able to see the high and low points of the sound based on the form. Although I manipulated the scale of the amplitude, the form also reflects how the song is low in volume most of the time. The x-axis (see Images 4a and 4b) is time in seconds, and the z-axis is the amplitude of the audio in RMS. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I proceeded with printing the 3D surface plot of the chromagram. Originally, I wanted to use the surface as the top of a box and tried to use Box and Split to create this solid. That didn&#8217;t work well, so I switched gears to use OffsetCurve. I liked this surface a lot more, and it illuminates how the music grows and dips in intensity throughout the song. As in Images 3a and 3b, the x-axis is time in seconds, the y-axis is the pitch classes (B through C), and z-axis is the normalized intensity of the pitches. The normalization would go from 0 to 1, but the song maxed out around 0.65. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, I returned to Revolve Surface for the melody form. The scale of the pitch frequency (Hz) on the z-axis was much greater than the volume&#8217;s amplitude, so I actually had to scale this form down rather than up. Though the x-axis is not the same scale, the melody form also uses the length of the song in seconds on the x-axis. The contour of the melody within the same is shown by this figure, and it seems like the melody stays at a relatively high frequency, which makes sense since the singer has a relatively high voice. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Images<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"986\" height=\"351\" src=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-12-150940.png\" alt=\"\" class=\"wp-image-13152\" srcset=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-12-150940.png 986w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-12-150940-300x107.png 300w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-12-150940-768x273.png 768w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-12-150940-920x328.png 920w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-12-150940-575x205.png 575w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-12-150940-380x135.png 380w\" sizes=\"auto, (max-width: 986px) 100vw, 986px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"496\" src=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71-1024x496.png\" alt=\"\" class=\"wp-image-13118\" srcset=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71-1024x496.png 1024w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71-300x145.png 300w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71-768x372.png 768w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71-1140x552.png 1140w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71-920x446.png 920w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71-575x278.png 575w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71-380x184.png 380w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/image-71.png 1338w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Images 1 and 2.

Final printed forms. From left to right: volume form, chromagram form, and melody form.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Reflection<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">I really enjoyed exploring how to physicalize data! The visual and tactile aspects of 3D forms make it more intuitive to understand the data patterns and trends. For the volume and pitches that I represented, it helped me listen to the song with more intention. It was interesting to listen after printing these forms and physically touch the same contours that I could hear in the music. It would be interesting to use different songs, especially ones from other artists and genres to compare the types of forms that can be generated from their music. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The chromagram was a completely new way of analyzing music, and though I can&#8217;t necessarily hear those details precisely when listening to the music, I could understand how the changing pitch classes made the music flow. The physicalizing process in general allows us to connect with the data in ways that engage different senses. I believe it also allows us to get more meaning from the data that we might not achieve through looking at numbers of graphs. For instance, this data might help us understand why some parts of the song make us feel more deeply, or why we like some parts of the song over others. It also might help us make connections between datasets &#8211; perhaps if I had printed similar forms for other songs, I could find a pattern of pitches that resonate with me.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Grasshopper Code<\/h2>\n\n\n\n<div class=\"wp-block-file\"><a id=\"wp-block-file--media-7ce81806-4041-4cec-a0ee-e020f77c4f60\" href=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/SachiBarnabyLA3.gh\">SachiBarnabyLA3<\/a><a href=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2024\/10\/SachiBarnabyLA3.gh\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-7ce81806-4041-4cec-a0ee-e020f77c4f60\">Download<\/a><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dataset I was interested in finding a dataset related to music for this project.
