    ReplayGain Codec "Disable Clip-Prevention" option. What exactly does this do/mean?

    Hi all

    I'm a bit unsure about that the "Disable Clip-Prevention" option in the RG Codec means, and what it does. Would someone mind spelling it out for me please?

    Cheers

    PS - While on the subject of ReplayGain, can I ask a bit of an OT question please? Is the following statement true:

    No matter what program is being used (ripper, converter, etc.), whenever ReplayGain is applied as a DSP, it is calculated on the source material, but whenever ReplayGain is applied using the RG Codec, it is calculated on the newly encoded material [I guess there is no source when RG is the codec].

    If you disable this option, then the player should work out that the values for replaygain would clip the audio and scale back the gain values, not all will so there is this option to do it.

    Thanks Spoon, that makes it a bit clearer, but to be honest I've got a bit of mental blockage on this one and I think I need it explained to me as though I was 5 years old! If anyone's got the time to that, I'd hugely appreciate it.

    At the same time, perhaps it might help if I asked some specific questions.

    1. Up until now I've been using RG v3 which I don't think had this option. So what was happening with RG v3?

    2. In my specific case, what would be the best option (although would still be nice to understand it fully)? I use Foobar for playback on my PC, and an iPod for music on the go.

    3. I am applying RG to some Mp3s I have. Up until now all I've done is used the DSP when ripping, so there have never been peak values above 1. But now that I am using the codec for RG on the Mp3s, I am seeing peaks well above 1. I understand why that is - the DSP calculates on the source while the codec calculates on the file itself, which in the case of Mp3s does mean peak values of +1. But I still don't get what bearing that has on whether I should have the Disable box ticked or not.

    Many thanks for your help and patience

    Please can you confirm how the user disables this option, tick or un-tick the Disable Clip-Prevention box?

    You would click it to disable.

    It does not have a bearing on the Disable box.
