    Hi Paul,

    Welcome to E2E!

    I will put together a quick overview on using the Digital Clipper post a follow-up.

    Hi Paul,

    Here are the notes on Digital Clipper. The spread-sheet can be used to calculate the Hex value for a given Clipper setting. However, note that the clipper control is spread across three registers (0x01, 0x10, 0x11).

    We will get this Digital Clipper control rolled in the next release of the PurePath GUI as well.

    Hi Ravi,

    I intend to use the digital clip level function in the TAS5760LD.

    However, I am confronted with a kind of attack/decay behavior which is detoriating the audio performance substantially.

    With a sinewave, it is working fine.  But with music you get a different behavior.

    In time domain, what you see is as follows.

    When the output reaches the clip level the first time, the output is hard clipped at the correct level.  But, it is as if the clip level is dropping for the next comming overshoots.  When the audio signal reduces, the amplifier comes back to the correct clip level.

    Is there a possibillity to disable that kind of attack/decay behavior?
    Or what could be the reasons for that detoriating sound performance?

    Regards,

    Christiaan
