Fetal and human PCG Data with the first and second heart tone segmentation for pNLF algorithm testing

Сontains phonocardiograms of the fetus and/or human, the first and second heart tones segmentation on the fetus and/or human phonocardiograms, the phonocardiograms after preprocessing and processing by the pNLF algorithm. The data can be used to reproduce the pNLF algorithm testing, or to test own algoriths for hearttone segmentation.
