YouTube is widely used for watching various types of videos, including audio recordings. The debate over the quality of audio on YouTube has sparked curiosity. The RVWSoc provided source files for two examples, revealing different audio streams offered by YouTube. Cross-correlation was used to align sample sequences and analyze differences between source and output versions. Results showed significant distortion in YT outputs, with some frequencies being entirely lost. Comparing YT outputs with BBC iPlayer flac streams showed unique differences in audio quality. The study raises questions about YT’s audio quality and highlights the potential for further investigations.
