    MP3 Re-Mastering feature

    I have just ordered this item and am wondering what this MP3 Re-Mastering feature is. Panasonic SC-PM602EB-K 40 W DAB/DAB+/FM CD Micro Hi-Fi with USB Playback and Wireless Audio Streaming via Bluetooth / Full Remote including an Audio Technica Headphone

    Will it automatically improve the sound quality of non-remastered CDs?

    And on a side note. I have a number of non-remastered Callas CDs plus one re-mastered one. Not altogether sure I prefer the re-mastered one. While the orchestra reveals more details and has greater clarity, Callas' voice sounds more strident and piercing not to say harsh (eg "Tu che invoco" from Spontini's La Vestale).

    If you search for "mp3" at http://www.panasonic.com/uk/consumer...c-pm602eb.html you will find what Panasonic claim for the feature. Basically it seems to enhance high frequencies in an attempt to replace what is lost in this region during the data compression process. I would quote the page but they appear to have blocked copying of the text.

      Thanks, Bryn. I have had a look at the link. If I'm right in thinking that CDs (i.e. parts of the high frequency signal) are compressed into MP3 files then the sound quality of CDs should be improved. Sorry, but I'm a total ignoramus on such things. It's not all that important as I just wanted a second DAB radio and thought it would be nice if it came with a CD player.

        Hummmm looks iffy to me
        All depends on the codec used to make into MP3 and bitrate etc etc

        To my ears the "problems" with MP3 are more to do with modulation (or the "drummer in the washing machine" effect!) than a lack of high frequencies.
        It would be interesting to have a look/listen to a file with and without this "feature"

          No.

          They are using the term "remastering" in a rather misleading way. They appear to be using it to describe converting the CDs to lossy mp3 (at what bit rate?) with some degree of treble emphasis.
