HUG - here for all audio enthusiasts

The Harbeth User Group is the primary channel for public communication with Harbeth's HQ. If you have a 'scientific mind' and are curious about how the ear works, how it can lead us to make the right - and wrong - audio equipment decisions, and about the technical ins and outs of audio equipment, how it's designed and what choices the designer makes, then the factual Science of Audio sub-forum area of HUG is your place. The objective methods of comparing audio equipment under controlled conditions has been thoroughly examined here on HUG and elsewhere and should be accessible to non-experts and able to be tried-out at home without deep technical knowledge. From a design perspective, today's award winning Harbeths could not have been designed any other way.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings area is you. If you are quite set in your subjectivity, then HUG is likely to be a bit too fact based for you, as many of the contributors have maximised their pleasure in home music reproduction by allowing their head to rule their heart. If upon examination we think that Posts are better suited to one sub-forum than than the other, they will be redirected during Moderation, which is applied throughout the site.

Questions and Posts about, for example, 'does amplifier A sounds better than amplifier B' or 'which speaker stands or cables are best' are suitable for the Subjective Soundings area only, although HUG is really not the best place to have these sort of purely subjective airings.

The Moderators' decision is final in all matters and Harbeth does not necessarily agree with the contents of any member contributions, especially in the Subjective Soundings area, and has no control over external content.

That's it! Enjoy!

  • Examples of zero* dynamic-range recordings

    Brilliant example, heard on BBC Radio 6 Music this evening. A sonic joy.

    Click on link here.

    I can't find the motivation to check, but I'd guess the DR is about 2dB between loudest and quietest elements of the recording. By means of factual contrast, even worn 78 shellac records had a DR of 30dB or more. Here.

    *or practically zero.Equivalent to a sledgehammer of sound coming at you at 100mph.

    A quick look at this track's RMS histogram seems to show that is has a Gaussian-like normal distribution, although the amplitude tail for the lower volumes are a bit stretched out. The indicated long term dynamic range is about 2.8 dB, which is very low. Your estimate of a DR of 2 dB is very close. Note that the difference between the maximum and minimum RMS amplitudes was about 6.3 dB.

      I canít get to attach a link, but google Reichís Clapping Music.
      There is a YouTube video of the performance and a LSO promo video of their recent release with Wood and Sextet. A great album, available in HD download.
