Flavio Pereira updated the Audio Signal Processing Guidelines documentation in the MicrosoftDocs/windows-driver-docs repository, focusing on clarifying the permitted processing for raw capture streams. He specified that only linear equalization may be used to flatten frequency response, explicitly prohibiting time-varying or adaptive processing such as echo control or noise suppression. Working in Markdown, Flavio incorporated reviewer feedback to ensure the guidelines were accurate and unambiguous for driver developers. His work improved the consistency and traceability of documentation, aligning it with digital signal processing best practices and reducing confusion for future contributors. No bugs were fixed during this period, emphasizing documentation quality.
