    JPEG XL - another guys want free income
    • A JPEG white paper titled JPEG XL Image Coding System explains that this new file format “fills the specific needs for responsive web, wide color gamut, and high dynamic range applications” and “provides legacy transition features and effective compression at high visual quality.

      Key features of the JPEG XL codec are:

      1. improved functionality and efficiency compared to traditional image formats (e.g. JPEG, GIF and PNG),
      2. progressive decoding (by resolution and precision),
      3. lossless JPEG transcoding,
      4. support for both photographic and synthetic imagery,
      5. graceful quality degradation across a large range of bitrates,
      6. perceptually optimized reference encoder,
      7. support for wide gamut and HDR,
      8. support for animated content,
      9. efficient encoding and decoding without requiring specialized hardware.
      10. Lossless JPEG transcoding reduces JPEG size by around 16% to 22%
      11. JPEG XL is visually lossless at about half the bitrate required by JPEG.

      In short - it makes zero sense at the age of HEVC based formats.

    Audacity will sell info about audio files you use to authorities and owners
    • The open-source software is now collecting user data for "app analytics" and "improving our app" as well as "for legal enforcement."

      Muse Group is collecting details about users' operating system version, processor, country based on IP address, crash reports and non-fatal error codes and messages. According to the policy, processing that data is in the "legitimate interest" of the company "to offer and ensure the proper functioning of the app."

      The data it collects on law enforcement grounds is more vague. The policy says Muse Group will capture "data necessary for law enforcement, litigation and authorities' requests (if any)." It may share personal data with "any competent law enforcement body, regulatory, government agency, court or other third party where we believe disclosure is necessary." Data may be shared with potential buyers too.

      To be short - software sends parts of all audio files for recognition and mark any file that has copyright owner. After this they sell this information in big batches to such owners to allow them to get big money from them. Main target for attacks are firms and individual workers with significant income who can use file without authorization or with wrong license. Before it was impossible to track this if you do not upload result to big online platform, but now offline software will track all of your actions and sell all this info to anyone who will pay for it.
