    Hi-fi audio signal chain -- no more sigma-delta

    You're right. Let me rephrase: a theory that has not yet been disproven.

    I hope those are not illogical personal attacks

    Phase in Audio Signals

    Thank you to all readers; I would like to expand on points #2 and #3 for the benefit of the community. The reason I am against digital filters is that I believe once the signal has been sampled, and therefore transformed to discrete time, further manipulations can only hurt signal integrity and...

    Hi-fi audio signal chain -- no more sigma-delta

    Maybe we can read it together, father.

    Hi-fi audio signal chain -- no more sigma-delta

    Thank you; however, that's not what I'm doing. My technique is simply to propose a theory that can't be disproven. That is the definition of scientific truth.

    Hi-fi audio signal chain -- no more sigma-delta

    jcx: While I can't say I appreciate the cynicism and utter lack of evidence in your post, I do appreciate your attempt to discredit my ideas. Hi-fi audio does require static linearity, and "perceptible distortion" is not a valid criterion for judging the fidelity of an audio signal.   -...

    ubecko,   I applaud your attempt to understand what's going on; keep up the good work. Your new friend at Head-fi, m3_arun

    Hi-fi audio signal chain -- no more sigma-delta

      I hold a BSEE from UCLA. You can make fun of my degree all you want.   Your claims about hearing processes are not relevant to creating a hi-fi signal chain. Whether we can hear non-linearities in the system is irrelevant to the fact that they are there; if digital audio was based on the...

    No, actually, you can't.

    Phase in Audio Signals

    Hello Head-fi; I'm back. This time to advance my views on phase linearity in the audio signal chain.   1. Only planar transducers (or phase-linear transducers) should be used in audio 2. Digital filters are completely unnecessary and counterproductive to hi-fi reproduction 3. The maximum...

    Hi-fi audio signal chain -- no more sigma-delta

    I want to pre-empt some of the responses that have yet to be posted; and this will NOT be my last post on the topic.   Delta-sigma manufacturers have used various statistical linearity measurements to cover up the lack of resolution of the converters. There is no substitute for static...

    Hi-fi audio signal chain -- no more sigma-delta

    Jokes aside, after doing some more independent research, I've realized that the parameter I am looking for is called "static linearity." I predict that the static linearity test will show the R2R coming out on top. Thanks to all for playing along for so long.
