generate low frequency tones smoothly
How can I generate low frequency tones smoothly? For example 7.83Hz, without making it sound like a pneumatic drill? Thanks for your help!
Re: generate low frequency tones smoothly
dont understand the real problem
low tones should be very smooth
they get a lot more samples to help recreate it
than the much higher freqs do
how are you creating it ?????
why does it sound like a pneumatic drill ? or why do you think it does?
how are you listening to it ??
could it be your playback and not the source that is a problem?

I've deleted to duplicate topic as I presume that it was posted in error.
7.83 Hz should not sound like anything - it is below the threshold of human hearing. If you are playing a 7.83 Hz signal loudly you may be hearing the sound of the speaker banging against the end stops (which it does not usually do for long before the speaker is destroyed).

Re: generate low frequency tones smoothly
Behold some of the problems of having Audacity do useful work outside the range of audio. At seven cycles, you should be able to see your speakers walk across the table or the grill cloth slapping against the cabinet. One of the earthquake waves -- Alpha, I think -- is around 7 Hz.
You can go the other direction, too. Audacity will generate tones so high they will fry your speakers and drill holes in your cat -- but you can't hear them.
Neither of them will qualify as "audio" any time soon.
Why do you need a "tone" that low and how are you listening to it?

Re: generate low frequency tones smoothly
There is a joke that all Hollywood earthquakes only have A waves because you can clearly see the wine glass walking across the table with the wine splashing everywhere, but you can't photograph a room moving at a 1Hz rate.

Re: generate low frequency tones smoothly
sounds like visual foley
most of that stuff is fake
cars dont explode
they burn violently
cars dont bump a car and then flip over it
there is a ramp hidden behind the car to make that happen
dont know why
but hollywood keeps making things more and more unrealistic
maybe cause the public is stupid enough to believe it
and how do two people running from a burning car know
exactly when it is going to explode (assuming that cars did)
and yell its going to blow up and jump towards the camera
onto the soft mats that are out of view just as it blows
i suspect the jumper has a button in his hand
to time it so perfectly
