[QUOTE="Nick Davis, post: 100821, member: 1713"] Re: strange or not strange! Although looked at this some time ago - decided to do some calibration tests between Reaper and the X32. a Question first on the oscillator screen - why if I use pink noise ( at 1K) and set the generate level to -18 dbfs - the output meter is fluctuating between -15Bdfs and -12dBfs. Ok recording oscillator tones in reaper - all set to unity. sine wave at -18dbfs records on Reaper at -18dbfs and then plays back on x32 at -18dbfs - fine pink noise - output from x32 -18Dbfs (peak)- ( generate level for oscillator set at -24Dbfs). - records on reaper about 2 or so Dbfs higher (peak at about -16Dbfs) - but plays back on X32 at same level as was originally generated. Obviously I do not understand the characteristics of pink noise - can someone explain. However - does not explain the original queries I had about the seemingly variation in playback level of same piece of audio! Ta added - looking at the channel input meter this seems to show a more constant peak - though there is a slight variation 1-2 Dbsf (BTW looking at the variation on the output this is / can be greater than my first observed 3/4 Dbfs 3-6) - in reaper the peak level is constant. So could it be to do with the drivers the interface card the x32 processing or a combination or is there a known reason for this type of thing, (or is it the meters not being terribly accurate!) ta again Nick [/QUOTE]
