Try setting the recording and playback setting to the "hw" options in the device toolbar, that correspond with the audio device that you are using. That will set Audacity to use the device directly through ALSA, bypassing PulseAudio, and should resolve the stability problems.

Each 16-bit sample has 2 bytes. Round your durations to a number of sample - it does not matter if you round up or down or to closest, but it is essential that you have 2 bytes for each sample. The code that you posted already appears to do that so far as i can tell, so my guess is that the problem ...

Does this sound familiar?
It is a sine wave with the low and high bytes reversed as signed 16-bit values.
Check that your code is always using an even number of bytes per tone.

That is very curious "distortion". It's not at all random, but has a very clear cyclical pattern that can be clearly seen in the Spectrogram view (http://manual.audacityteam.org/man/spectrogram_view.html) Set the "Window Size" to a small value (say: 128) to see the pattern. My fi...

So it's not really "Make-Up Gain." In the "Limiter" effect that now ships with Audacity (http://manual.audacityteam.org/man/limiter.html), it really is "Make-Up Gain", (not "Normalize"). It looks like that's the effect that Trebor is demonstrating. In this pl...

Worth noting that with real-world sounds, there are always harmonics present. Although the frequency resolution of FFT gets progressively worse at lower frequencies, for many sounds it can be expected that the first harmonic will be exactly double the frequency of the fundamental. In terms of "...

On one of my chapters it appeared at 20.59 in the recording but was not linked to the actual sound at that point. I changed the tempo of the recording and the sound came again at exactly 20.59, this time over different words. That second sentence give an important clue. It shows that the sound is n...

sounds that ought to be gentle sine waves come out sounding like machine clanking. Please post a short sample in WAV format . Just a few seconds will be fine, so long as it clearly shows the problem.
