The minimum is always zero. Every time there is a zero crossing point the amplitude is zero. So how are you going to measure "minimum" in a meaningful way?

It is basically a speaker tweaked to deliver vibrations (http://www.atactech.com/PR_tactors.html ) It's nominal frequency is 250 Hz meaning that the optimal vibration is achieved when playing a sine of 250 Hz. It can go up or down a bit, that's what I plan to do, but the equipment just requires a s...

I am using audio signals and I have equipment that allows me to transfer these signals through vibration to the skin. Tell me a bit about this equipment. What sort of signal does it require? Does it require just the modulation wave or does it also require the carrier? If it requires the carrier, wh...

It sounds like an interesting project. I've split this from the original topic as it will require a somewhat different approach. So I basically want to modulate the base pitch differently (use different frequency for tremolo), depending on what band of frequencies it belongs to. The bands I gave in ...

It would be far more simple to use a command line program (such as SoX (http://sox.sourceforge.net/)

So I have say a sine wave tone varying between 50 - 200 Hz and I want to create three different tremolo frequencies based on the frequency of the sine wave. For example: If input wave is between 50 - 100 Hz: use tremolo with a 30Hz frequency If input wave is between 100 - 150 Hz: use tremolo with a...

Thank buja. I have a question about the Cross-Fade Overlap setting... It's a percentage...but a percentage of what? The total time of the selection? It's a percentage of the "patch" (see the second picture in the first post). In other words, a % of half of the selection. If set to 50%, the...

Topic moved to "General Audio Programming". You would probably do better to ask this type of question on the Portaudio mailing list. The Audacity developers rarely come to the forum, and when they do they generally only respond to questions that are specifically about Audacity. See my prev...
