    Hi. I was playing around with different plugins in the VST and I realized that if you choose a Winamp dsp plugin dll, Breakaway One recognizes that it's a Winamp DSP, but will not use it. So clearly this must have already been considered, but would it be possible/feasible to add support for Winamp DSP plugins? Or is there some legal reason this cannot happen?

    Thank you,
    Ty

    Indeed I check for it so that it doesn't try to use it as VST, because it crashed otherwise :).

    BreakawayOne uses 24-bit samples with 8-bit headroom (so levels internally can go to +48dBFS, not limited to 0dBFS).
    VSTs are 32-bit floating point, which means 24-bit resolution with essentially infinite headroom.
    So, if you feed a 0dBFS clipped modern loudness-war master into BaOne without attenuation, and then run a VST de-clipper, you will have +12dB or maybe even +18dB peaks, which is perfectly fine because BaOne has the headroom for it, and the AGC will push it down to where it should be.

    Winamp DSP plug-ins, on the other hand, use 16-bit samples and has NO headroom. So, if you wanted to do a de-clipper as a Winamp DSP plug-in, you would need 12 or maybe even 18dB attenuation to avoid clipping in the DSP chain.

    18dB.. that's 3 bits. So you'd be down to *13 bits* of audio data!

    That's just not enough to be useful, so I skipped it completely.

    Best regards,

    Leif,

    On this subject, you mention that using a declipper without attenuation would produce these very high peaks. In my situation, I use ReplayGain to tag all my flac and the few MP3s I still have to the standard 2.0 setting of -18db. Would you say, in my case, that I wouldn't need to really attenuate further in the declipper to avoid those high peaks (even though your system handles it well enough)? What would be ideal?

    Hi Timmy,

    A sensible replaygain level should definitely be enough, because the whole point of replaygain is to attenuate loud tracks to the point where they're no louder than older, properly mastered tracks.. and as such that should be all the headroom they need, even after declipping.
