  1. Re:So essentially... on New Camera Sensor Filter Allows Twice As Much Light · · Score: 1

    The real problem is that a so-called "RGGB" sensor isn't. It's actually (white-R) white white (white-B). So this isn't a 2x brightness increase: it's barely 10%.

  2. Re:Interesting. on Raspberry Pi Model A Makes First Appearance · · Score: 2

    That "white spot" is the ground plane + heat sink for the ethernet/usb hub IC.

  3. Re:Here's an idea on Feds Unwrap $15M For Corporate Energy Reduction · · Score: 1

    Augh. No. Peak power dissipation is not average power dissipation. A laser printer or copier only uses that much power while printing/copying. My laserjet goes down to ~50W in power "saving" mode when it's not printing.

  4. Re:Old Sun hardware is always neat on Good Vintage Computers? · · Score: 1

    If you can muck up an old SGI, those are pretty neat, too. (But openprom is beautiful; I've been using a SparcClassic as an email server for the past 4 years now.)

  5. You want a compander. on Normalizing Music? · · Score: 4, Informative

    What you want is a compander. (compressor/expander). It is so called because it compresses or expands the dynamic range of the input audio. Sox includes one, if you like command lines.

    For winamp, I've found Rocksteady is beautiful, and does separate compression for several frequency bands (i can't begin to express how good this is for pop/rock).

    For XMMS, AudioCompress does a sufficient job, although the windowing is somewhat stupid (not predictive == you'll get pops if things suddenly get loud) and it doesn't separate into multiple frequency bands, so it won't sound so good if you're playing something where the bass is really pushed (like Fiona Apple) next to something where it's not (classical).

    Neither allow you specify complex transfer functions (of input volume to output volume).

    For your purposes, sox is really the right thing, although it may feel a bit like "ack! drowning in sea of unexplained options!". You could start off trying:

    $ sox infile.wav outfile.wav compand .1,.1 -60,-10 0 0 .1

    will give you VERY hard compression. Change the .1s to specify how fast it changes the volume; change the -60,-10 (always negative) to more similar values to make the compression less severe.

    $ man sox
    will tell you something more.

  6. Two programs that weren't mentioned on Music Related Free and Open Source Software? · · Score: 1

    If you're going to mention CSound (or FluidSynth), you should mention its complement (or uglier relative) PureData . PD is a Max/MSP clone, and one of the earlier programs to support JACK. By now, between PD, JACK, and ALSA's MIDI layer, you can basically do everything you can do in Max/MSP (OS9 and only recently OSX) under linux.

    This is not to say that PD is necessarily a good introductory sound program -- after all, it is rather strange to right music using flowcharts.

    The other I know of and think highly of that I didn't see is Bristol, a soft-synth.

  7. Re:I'll surely bye it, if... on The Fridge of the Future · · Score: 1

    It runs some M$ crap ... either Win9x or WinCE - if you look at the realaudio stream for "external communication" you can see the "internet exploiter" icon sitting there, briefly.

    The good news is that if it runs win9x i know SOMEONE can figure out how to install linux on it.

    Amazingly enough we haven't /.ed electrolux but I suspect we are overloading their realplayer server.
