Live vs conserved music or Lugansky vs Residentie Orkest
or Rachmaninoff and Socionics

We've just returned from this concert in The Hague:

Elgar, Enigma-variations Xian Zhang, conductor
Sergey Rachmaninov, Piano concert nr. 3 Nikolay Lugansky, piano, Xian Zhang, conductor.

Residentie Orkest The Hague Philharmonic

Mixed feelings and a helluva thoughts (Yeah, as always). OK, one by one…

How to downmix 4 channels into 2

Or a quadraphonic record into a stereo one.

Le's assume you have a bunch of files in one directory. The following script will downmix 4 channels into 2 with the following proportions:

  • LF => 100% LF
  • RF => 100% RF
  • LB => 100% LF
  • RB => 100% RF

and move the stereo files into a directory called "stereo":

mkdir stereo
for file in $*
do
sox -S -c4 "$file" -c2 stereo/"$file" mixer 1,1
done

If you want to change the front/back ratio to, for example:

  • LF => 100% LF
  • RF => 100% RF
  • LB => 70% LF
  • RB => 70% RF

the sox command will look like:

sox -S -c4 "$file" -c2 stereo/"$file" mixer 1,0.7


Finite Elemente – The Resonator

I'm a big fan of Finite Elemente creations. I had or still have Spider and Master Reference Pagode racks, Ceraballs, Cerapucs, Cerabases… All of them brought a great deal of enhancements in dynamics and resonance dumping. So I thought that The Resonator will definitely not hurt and hopefully bring me closer to There. The idea was to use it on top of the Transporter, which is known for its thin ringy tincan case. But considering the price (319-400EUR in Europe, $550-745 in the US) I decided to audition it first and borrowed one from my dealer.

From the description and ad campaigns:

  • Diameter: 120mm
  • Height: 30mm
  • Weight: 370g
  • Material: anodized aluminium (silver or black), stainless steel insert
  • The Resonator converts the resonance energy into heat across a broad band, instead of relocating its spectrum or generating new intrinsic like conventional attenuation of component cabinets, using mass blocks, for example.
  • Strategically placing the Resonator in a resonant zone on your component's chassis, can reduce vibration by more than 20dB

This is what it looks like:

Porcupine Tree and the loudness war

Porcupine Tree - clippings Porcupine Tree - clippings

Porcupine Tree - clippingsThis is the second track from Porcupine Tree "Deadwing" called "Shallow".

WYSIWYG… It sounds just like the graph in SND.  Especially if upsampled without decreasing the volume – like badly scratched disk. And yes, loud. Can it be any worse?

/usr/local/bin/sox effects: polyphase clipped 329755 samples; decrease volume?


Eva Cassidy and the loudness war

Eva Cassidy - Time After Time - The Letter Who could have thought that Eva Cassidy's album "Time after time" (one of my favourites, BTW) would have been recorded with such clippings?

See an excerpt from "The Letter"  on the left.
