Screensaver reacts to ambient sound. (was audioparticle, audioparticolor)

Overview

audiospectrum is a very simple quartz screensaver that reacts to ambient audio. It's simple as possible to keep processor load and heat minimal. This is the good one, in my opinion, the screenshot really doesn't do it justice.

Click the 'More Information' link on this page for all the other audio-based quartz screensavers I've made. I may try to combine some of these, but keeping CPU use low is the priority.

To use these create (if it doesn't already exist) a folder called "Screen Savers" in your ~/Library folder and place the file there. It will then be available in ScreenSavers preference pane.

Note: If you are using a PowerMac or other computer without a built in microphone, you need to either adjust your default input in Sound Preference Pane so the screensaver can "hear" it, or email me or leave a comment if that doesn't work, so I can provide a version that monitors the line in. (I don't have a computer like this to test it on.)

What's new in audiospectrum

I figured out how to separate the audio spectrum, so there is a low, mid, and high band! The color of each band depends on the relative strengths of each band so it's kinda interesting actually, and it's quite responsive.

All previous versions and others are available in the More Information link on this page.

I'd really love to figure out a way to have this always record the last few seconds of audio so you could stop and capture spontaneous wierd audio outbursts for posterity. Anyone know if this is possible at all?

Hi - I really want to be able to use this on my Power Mac with 30" screen. All of the .qtz files I've tried to use as a moving desktop eat up too much energy and slow down other apps. I've got 4 gigs of memory which I assume should be more than adequate. Does anyone know of any clean, simple quartz files (they don't need to be sound activated)? Vicki.qtz is good but not simple enough. Please email jw@jessewaugh.com if you know of any. Thanks

How does the AudioSpectrum work? What are the frequency range for each band? Can you break it up into more bands? (I'd personally like it in a 31 band (third octave) setup!) Very cool, and I'm excited to see where this goes!

what I did was select 3 (out of 12) representative spectrum bands, a low, a mid, and a high. Everything in the screensaver is based off a mixture of these readings, and the total volume. I didn't use all 12 spectrum bands because it starts using quite a bit more of the processer, and i want to keep these lightweight. I will probably make something that uses all 12 bands, i've also run into a couple that other folks made, like (http://www.quartzcompositions.com/phpBB2/upload/details.php?file=62)

These are all really cool. I don't suppose you could turn them into iTunes visualizers?

Never mind about the iTunes visualizer. It looks like QCDesktop will meet my needs.

Great concept! But it should do something when there is no noise, otherwise it looks like the screen is off. Maybe increase the sensitivity a little?

you might need to adjust your audio input in the Sound control panel in system preferences.

I'm guessing that PowerMacs don't have a built-in microphone. There was an option I could change in Quartz Composer to have it read from line-in, which might (or might not) be independant of the Sound preference pane settings. I wanted to make it on option, but it seems I can't. I don't have a PM to test this on, but here is a link to a version thats set to listen on line in. http://cutup.org/code/quartz/APC_line_in.qtz Anyone that tries this, please let me know what worked? If you needed to run this version, or if the sound preference pane could be used to set the input. Thanks

Great concept, but this really needs additional cycling colors or something plus multiple particle types and animations. Can't wait for a 2.0!
