variation on multiple audio tracks

-

hello , i'm newbee ,pardon bad english, i'm trying manage volume of 4 separate audio tracks , arduino ,something applying variable resistance (applied digitalluy) sensors, when approach sensor (ir or ultras) changes volume of relative output, phisically input audio signal in arduino , let edit , output box , 4 separate audio channels , boxes.
so , hope i've been enough understandable,sorry again if i'm maybe o.t..

look digital potentiometers, such these maxim:

basically, act regular potentiometer control volume level, can controlled digitally, of course.

nothing routed through arduino; not sure arduino have processing power sample 4 analog signals in real-time, change levels, , output them; wouldn't have pins output them individually - though see software mixing outputing via dac, or maybe multiple i2c/spi dacs?

hope helps!

:)

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
