You are facilitated with the ease of availability of this software since it is open source and most importantly, free of cost. When you need to record both the ends of a conversation being held then AUDACITY may not be your best option.

I believe the links you gave are the same calculator I used when I designed a variable-frequency lowpass filter for a little powered sub. This way, you reduce noise and phase distortion by the number of components in any particular signal's path. The 5kHz highpass goes straight to an output, and the 50Hz, 150Hz, and 1kHz highpass filters cascade into their respective lowpass filters (at 150Hz, 1kHz, and 5kHz). I might go from an input buffer to high-pass stages at 50Hz, 150Hz, 1kHz, and 5kHz, plus the lowpass at 50Hz. You can combine them if it makes sense, but I might choose a more parallel layout to reduce the number of filters in any given signal's input chain. So all that said, yer pretty much just saying that i start with my original signal, split it into a low-passed and a high-passed, Send the low to an amp/speaker and send the high to the next set of filters and then repeat until I get my number of speakers? Really it seems simple, just a matter of getting design well down. Looking it, up I can find some equations for deciding on the components. You could control those with an Arduino, since you would just be sending control signals rather than doing DSP. If you need variable crossover frequencies, I believe there are voltage-controlled filter chips and digitally-controlled filter chips. The PWM "analog" outputs are clearly not fast enough for quality audio.Īnalog filters are probably the easiest if you are going to build something. The ADC is only 10 bits, and I don't believe it's fast enough for 20kHz audio. In any case, you'd need separate ADCs & DACs.


I'm not a DSP expert, but I don't believe the Arduino by itself is fast enough for audio DSP. (Watch-out for "virtual 5.1" if you buy a cheap one.)

outputting 5 signals simultaneously given to it over USB? Is it OK to dedicate a computer for this? Assuming you know how to do audio programming on a PC or Mac. You could probably do this with a computer and a 5.1 channel soundcard (two soundcards for stereo). If the computer is processing & filtering, what's the Arduino doing? So I figured, why not use a computer program to process and filter the audio and then tell the arduino to output each band.
