Sloppy Noto is a data audiolizer. It turns numeric data into sound.
-
🚫 Noto does not oscillate or generate sound waves by other means based on given data, modify any such waves, or take artistic liberties.
-
✅ Noto does interpret given series of numbers directly as digital audio signal sample magnitudes by rescale and interpolation. What you see is what you hear.
Sloppy Noto was originally developed to generate audio files from the raw data collected by various instruments on European Space Agency and NASA space probes. However, Noto is versatile and can process any delimiter-separated values format containing extensive numeric data (44,100 rows of numeric data = one second of audio).
Suitable file types include (but are not limited to) .csv, .tsv, .tab, .lst, .asc, .log, .xls, .xlsx, .json, .xml, .kml, .kmz. Archive files .zip, .tar, .gz also work as long as there is a single file inside, that is also suitable for Noto to read. Files can be used directly from URLs, or from Google Drive.
Sloppy Noto runs in Google Colaboratory (i.e. your browser), using your Google Drive as data source and/or storage.

crawlers.ipynb is a data crawling utility notebook for finding suitable data file candidates for data to audio conversion from online data archives. It contains an HTTP Crawler, an FTP Crawler and a ZIP Crawler, each listing files recursively from a URL, making educated guesses on what might work, based on file extensions and sizes.
