I would like to generate a single continuous tone (eg. a sine wave) from a web page with the ability to interactively control the following:
- start/stop sound
- change pitch
- change volume
I'm after a solution that is reasonably likely to work on a wide variety of hardware, browsers and connections; something as simple and low-bandwidth as possible.
The only method that seems to work reliably across the hardware I have access to is Flash, but I'd really like to avoid a proprietary solution and create something with open-source software that conforms to open standards.
Is this possible?
If so, how?
