It's the same on WIndows, Mac OS and Linux. As I previously suggested, you had not given sufficient detail. If you set the time format to "samples", then you will see 500001 samples, which I presume you agree is the correct number of samples in 1 second when the sample rate is 500001 sampl...

Try using the Limiter effect http://manual.audacityteam.org/man/limiter.html Reducing the peak level by 6 dB is equivalent to reducing the level by half. So, if you first Normalize (http://manual.audacityteam.org/man/normalize.html) to 0 dB and then set the Limiter to: Type: Soft Limit (default) Inp...

Low level noise can be reduced with the Noise Reduction effect, but you need to have a region of the recording that has only the low level noise. It is not generally possible to remove loud sounds to reveal quiet sounds that are masked by the loud sounds. If this question is regarding a covert recor...

I guess there's some important detail missing from your post, otherwise:
Use an iPhone, dictaphone, or anything else that can record at the press of a button, press the record button, and say the word 20 times, leaving about half a second between each word.

Probably easier to just generate it as one sound. For example, try running this in the Nyquist Prompt effect (http://manual.audacityteam.org/man/nyquist_prompt.html):

Out of interest, I tested with Audacity 2.1.2 (I don't have 2.1.3 installed at the moment), and I can't reproduce the problem in 2.1.2 either. Perhaps your steps to reproduce are not detailed or precise enough.

For sine waves, it is very easy using the Nyquist Prompt effect (http://manual.audacityteam.org/man/nyquist_prompt.html) The "Nyquist" scripting language has a built-in command for generating sine waves that takes the MIDI note number to select the frequency. 1) Select part of an audio tra...
