Sound quilts were created according to the algorithm proposed in a previous work41. The balanced training dataset (Fig.4) was used as the quilting source material. First, the original sound sources were divided into small segments of equal size (50–1600 ms in octave range). Next, these...
The prototype was implemented and developed using Python and the Google Colab environment. Preliminary results were obtained using a free music samples data set, but the algorithm can be scaled and optimized for larger, more complex data sets. Mobile versions of the algorithm can be included in ...
