    • Thanks Andrea…it looks to be an excellent read. I’m not sure it will change the habits of music producers and mastering professionals, but at least broadcasts will be leveled.

    Why can everyone have their cake and eat it too?
    We are in 2015, digital downloads and streaming are in and physical media is going out. Why not just make a non Mastered Album? From that Master you can have all flavors of audio quality and formats you want.
    1. Pure Audiophile Grade
    2. Super Compressed for portables
    3. A 130db hot version for deaf people
    4. DSD, DXD, Flac, MP3, etc, etc, etc..
    We all can win.

    Mark, have you watch any of Ian’s Dynamic Range Day presentations on Google+? I sat through the one last year.

  • I agree with offering several versions. The biggest issue where it makes any sense is listening over car systems and over ear phones off your smart phone when out and about. To me the solution could be simple. Offer the finest version you can without loudness considerations. Have all the normal playback equipment offer two or three levels of compression which can be switched on or off. Select what makes it all clear to you in the car, leave it off when at home or quiet places. Have your cake and eat it too.

    Yeah, I know, good luck with making that become the standard.
