Common Mode Rejection is a function of the current match between the two sides of the balanced line. Absolutely. With a balanced input signal, you have a voltage differential - the voltage on each line is referenced to the voltage on the other - a kind of push/pull relationship. Ohms law I=V/R The ...

I don't know of any analysis tools that will produce numerical outputs, but you can see on this image (a cowbell hit) that the attack is 86 samples duration. The sample rate of this recording is 44100 Hz, so the attack can be calculated as 86/44100 = 0.00195 seconds = 1.95 ms (Click on image to expa...

Just to make sure that any frequencies > 4 Hz don't fold back (due to roll off of low pass filter in Audacity) it is better if FIRST you pass your data through a lowpass filter (bandwidth 4khz) and THEN do the downsampling as suggested here. That shouldn't be necessary if you have Audacity Preferen...

Your welcome

True differential. The input impedance on the two inputs should be matched as closely as possible for maximum CMR (common-mode rejection). The SM57 is designed to be used with a low impedance load, so the overall input impedance (across the two inputs) should be somewhere around 500 to 600 Ohms. If ...

I've got a script, a cast of four, someone's dining room with a nice big dining table to sit around, and a laptop. What a fantastic prospect :) The two elements that you miss out are: 1) This is: just for fun. for local hospital radio, a demo to catch the interest of a producer, the start of a new ...

You could be in luck. Over that past few weeks there has been some work done on the Noise Removal effect in Audacity 1.3. It hasn't been officially released yet, but I am testing it at the moment and it is looking very good. The down side is that it is not yet fully documented, but most of the featu...

I am using XP Well that blows out that theory :D it worked fine until I changed a few settings Any chance you can remember what settings you changed? How did you change left and right inputs? What sort of leads are you using into what sort of sockets? (don't spare the paper on this one - I'm trying...

It's difficult to know what I should be listening for, but I don't notice anything that I would describe as "a strange background noise that "moves" up and down with the song". I do notice that there is a little bit of distortion in a few places (sounds similar to the type of cli...

Would you by any chance be using Windows Vista or Windows 7 ? If so, you probably need to set the recording format to "44100 Hz 16 bit stereo (CD Quality)" in the Windows Control Panel. There are instructions of how to get to the recording settings in the Control Panel here: http://wiki.au...
