I wonder if these hissy and noisy classical recordings use the full 16 bits? If you are recording live audio, you don't know in advance exactly how loud the maximum will be. So you have to waste some of the available dynamic range for headroom. If we have, say, 24 bits input, then after the recording is over we can normalize it so that the loudest sample just hits FFFF and use 16 bits from there on. That way we really do have the full 16 bit dynamic range for output. Another problem is that music waveforms tend to not be a pure sine wave. If you look at a trumpet waveform you need a lot more headroom than you might expect, to avoid clipping the peaks. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
