Ok. So a cd sample is 44100hz and 16 bit. The sample polarities are between -1 to 1. I think it just polls the mic at these intervals to get the air pressure in analogue before changing it to digital though im completely ignorant of that process. The way your describing it in analogue form...

Yes, it will be converted to voltage at some point in the pipeline to actually hear it out speakers but it cant just be stored as voltage, but rather digitally. Like th audio is stored on usb or hd or on cd or in computer ram and it has a format in binary. The 1 and -1 represent the air...

Hi, sorry for the confusion. The -1 to 1 value is how the audio is stored in digital memory. Eg, cd audio is 16 bit, so there are 65536 representations per sample represented as 1/65536 steps). This is the audio i want to low pass filter but now im becoming aware that i need to have my...

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...

Thanks for the reply, ill look into those links.

Thank you Art. Ok, so the audio inside the analogue hardware is measured in voltage that makes sense. However because audio fluctuates between two limits(at a given amplitude) what are those values at base levels?(without amplification). Im assuming there is no such thing as a negative...

Hi, Im just a newbie here and im trying to program a low pass filter on c# with .wav files. After looking online ive spotted some math formula for RC analogue low pass filters and these formulas i believe are based on voltage. My question is, before the audio is sent to any filter in analogue...
