Is Pink Noise or Sweeps preferred when doing calibration?

Both are useful. Pink noise is arguably the easiest tool for setting levels and doing RTA measurements. Sweeps are useful for many other measurements.

All other channels are muted while producing the sweep for a particular channel but I don't have top middle and front wide channels to test (interestingly only the channels I don't have are problematic). These 256k long TrueHD sweeps were created more recently and in the very low probability case that I have done channel muting mistakes, it's extremely unlikely that I have repeated the exact same mistakes in these ones:

Let me know if FW and TM channels still have the problems you have mentioned.

Hi @serko70 - were the FW and TM channels issue resolved in this version? Did anyone confirm?

Also, @sumo complained about the wides and surrounds, not wides and top middles.

I had created lossless M-Noise sweeps a while back (mkv format, 46 seconds each). They are all at equal volume to each other with dialnorm settings off but there's no easy way to measure their dbFS levels accurately. Still, it will help with level matching probably even better than pink noise as they have higher crest factor:

Can you kindly avail these in the form of a download link.

These lossless sweeps are the latest and are perfect including FWL & FWR and no spill problems either. LFE sweep (SWx.mlp) already has -10dB embedded.

Thanks @serko70 much appreciated. Is there a video where you've shown how to setup and use these?
