I'm ready to buy an XLR to USB cord Most reports that I've read about XLR to USB cords (cables / leads) is that they're very poor unless you happen to be recording from something with a very high signal level (such as a mixing desk) but then you have to be careful to avoid clipping. From what I've ...

The new default settings are pretty close to the settings that you were previously using. http://manual.audacityteam.org/m/images/5/5e/noisereduction.png The new version should be able to produce better results than the old effect, though you may need to tweak the settings a bit. If you can't get re...

For specific types of "noise", filters can work better than "Noise Reduction" effects. A typical example would be where the "noise" is a constant hum or whistle with only a few frequencies, in which case Notch filters can be used to cut those frequencies.

We know that for frequency F Hz, there are F complete cycles in 1 second, an if F is a whole number, then the number of complete cycles in 1 second will be a whole number. So what we need to do for a decimal number, is to look for a frequency that is an exact multiple of F and is itself a whole numb...

Is that for G#5/Ab5 at A440?

Try 100 seconds

or 3,200,000 samples (33.333 seconds)

But where does 68991 come from? I looked for the closest number of complete cycles to your figure of 7973856 samples. To do that: We know that 1 cycle is: "(sample rate)/frequency" samples. How many cycles in 7973856 samples = (number of samples)/(samples per cycle) Which gives us: 797385...

A frequency of 830.61 Hz has a period of 1/830.61 seconds. At 96000 Hz sample rate, to convert seconds to samples, multiply seconds by 96000. So a single cycle at 830.61 Hz would be 96000/830.61 = 115.57770795 sample periods. 68991 cycles of 830.61 Hz at 96000 Hz sample rate would be: 1 cycle period...

All the Steve Dalton plugins are missing on the Mac. My Windows and Ubuntu systems have no problem with those plugins, just affecting the Mac El Capitan version. Are "High Pass Filter" and "Low Pass Filter" also missing? Try grouping the effects by type. Do you have any Nyquist ...

Audacity 2.0.6 That's now obsolete. The current version is 2.1.2 and is available here: http://audacityteam.org/download/windows . What is the maximum number of "Operator Actions" that Audacity can accommodate? I don't know the exact number, but it is a very large number. You're more like...
