I see. I will experiment further. The sound card DAC levels are at 0dB. Set by the mudita24 utility for the 1010LT card. One thing you mentioned is to lower down the volume after an export with normalization, whereas I expected to be the same as what I have mixed. Also the recording levels are barely reaching -24dB. This might be too low. One Harrison tutorial, one gain staging I think, mentions that with DAWs it is preferable to record at a lower volume, like -15dB, and then to enlarge the waveforms in the DAW. It might that the problem I have heard with normalization in this soft piece is due to having a too low amplitude in the waveforms to start with. I will try to remix by first adding gain to all the waveforms, in respect to each other, so that they reach a higher gain. > If the CD has both pieces that should be loud and others like yours > that are meant to be softer, then you did the right thing.

My main objective would be for the listener to not have to adjust the volume for the different dynamics, a tranquil piece being naturally softer in dynamic terms. There are many examples out there of softer pieces on otherwise dynamic CDs that nevertheless gets across without having to reach for the volume knob. This is what I would like to have. > Your track has quite a low level, even if it is intended to be soft. > Ebumeter says the loudness is -3.7 LU.

In this respect having the LU values when exporting can act as a reference, I presume. > It's a real shame that Ardour only offers peak normalisation.

In all the articles I read and videos I've seen on mixing so far, there was no attention given to normalization when exporting, in otherwise detailed articles. Is this extra processing something that all DAWs are doing by default and taken for granted ? _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
