    Digital clipping is by nature basic hard clipping. Just clamp it on a given value and never exceed that.

    Let's say you're using floating point samples and you've calibrated -1.0f to 1.0f to be your dBFS.

    Then just for each sample multiply by a gain factor > 1.0, and simply clamp it to 1.0 maximum (with sign)

    Code:
    sample = sample * gain;
    
    sign = (sample<0) ? -1 : 1;
    
    if(abs(sample) > 1.0)
       sample = sign;

    Check it now, you prolly listened when I was messing around.

    What I'm playing right now is as far as I've gotten.

    And it doesn't suck for being digital clipping..

    Just my opinion, but I think you're approaching this the wrong way.

    I'd rather have the source (i.e. the stream) to be as neutral ("as recorded" neutral) as possible, with just basic volume levelling at play.

    Then leave it to the listener how they want it to sound. This approach has validity as I don't view EQ / compression / enhancement as necessarily a bad way when listening on shitty earbuds (it happens, don't chastise me). But even on my rough-and-ready setup on my home/work-desktop with basic monitors (Rokit 5s) I'd not want any processing to be done.

    So if you want this approach, you might want to create a player app (either general or just your streams) with settings to adjust the amount of processing done.

    This is not to say you shouldn't do things on the source end, again, level settings need to be tweaked for a solid stream, but you might look at compression settings (like bitrate and codec) for the best bitrate/quality payoff.

    I know that if I had read up on Bob Katz, I'd just throw this shit in the bin -
    BUT - I've bruteforced myself this far for a year and discovered some weird and wicked stuff (like how they hide entire songs in songs, which you can hear by changing ASIO Hz.. :)

    The intention is for all speakers to be maximized without having to EQ or boost or such and so.

    Right now the mids are reinstated, please have a listensy. <3

    That still doesn't sound good. Tell me where are you streaming from?
    What software do you use? Do you know the "Open Broadcast System"?

    I reworked some parts, and the stream is much better now.
    "Never heard such fidelity" a friend said.
    No Digital Clipping now, focus on quality :)
    I'm using Spotify, streaming via Mixlr.
    I know OBS, been doing a bit of YouTube as well :)

    Your friend is either:

    1) Deaf
    2) Lying to save your feelings
    3) As deluded as you (are they also listening on a "phat system"?)

    The stream sounds absolutely horrific. Nirvana was playing when I clicked it, made me want to put a shotgun in my mouth...

    Compression artifacts everywhere, the high end is completely destroyed, the midrange sounds hollow and out of phase, like you've put some kinda shitty boombox "surround" effect on it. Cymbals sound like throwing a bag of broken glass down the stairs.

    Bass has zero dynamics, and therefore no impact/power whatsoever.

    Oh, and even turned up to 11, it sounds significantly quieter and smaller than the original recordings.


    On the plus side, it did make me feel kinda warm and fuzzy (for like half a second), given how strongly it reminded me of a 56k Realplayer stream circa 2000.


    Actually, now I think about it, that's kinda an insult to Realplayer.

    This extended reply made my day. :)
    Can you check it now?
    According to Analyzer it's balanced AF now

    And some info:
    I am upscaling to 25MHz, and I also AC3 encode it then DTS...
    That's like 1/10 of the puzzle.

    Well, you've had your fun, but for your next trolling attempt try being a bit more subtle.

    Want screenshot in PM or what?

    If it rubs your soul;
    I have a program that I can enter whatever Hz I want.

    It's custom made Matlab stuff.
    Anyway, right now I have a digital to analog to digital chain going. It sure sounds good.

    Thank you for the butchery so far, we're progressing faster a la TrUeSSR

    Log update:
    I've expanded on the digital -> analog -> digital circuit, and I like the analog sound.
    Note that the radio stream is intended to maximize each speaker without the need of excessive configuration.
    It's the whole point.

    Thank you, that means a lot.
    If you know any tricks to improve the stream further, let me know :)

    Today I'm playing with an old plugin that seem to be giving the audio some more clarity,
    currently I'm at way's end regarding ideas on how to gain more fidelity. :)
