[QUOTE="Kevin Cockburn, post: 217548, member: 16168"] Thank you for your response. The c# i meant(but sadly ommited) is the programming language, not the actual note(although its quite a comical crossing of wires 😃) I wasnt aware of such thing as negative voltage. I think thats the biggest wow moment for me. In memory on computer sounds are discreet samples measuring between 1 and -1 and i was unaware how to convert that into voltage...i was overcomplicating things, but minus voltage actually makes this a lot simpler to convert. So now i have to study up on decibels and then ill be able to plug these formulae in and hopefully get a result close to actual low pass filter outputs. Although it may be a bit more difficult because low pass filtering a 1v waveform will probably produce a different result if low pass filtering say a 40v waveform. That would require dealing with these samples outside their +/-1 limits. One way would be always to normalise the sound which i think is how a digital low pass filter would work anyway... [/QUOTE]
