Re: Looking for a app similar to the Dog Whistle for the iPhone
Thanks again, I don't know anything about Python programming but where would
I label the inputs for the frequency and the volume at? I can easily make
the changes to the frequency, a dog whistle is anywhere from 16000 to 22000
Hz and for the volume anything over 0.1 is to loud the speakers on the
FreeRunner struggle with it, what I mean by that is 22000 Hz sounds lower
than 17000 Hz.

Tadaaa! Hope pasting it into an email doesn't ruin the formatting. This
is my first pygtk/pygst program and it has been cobbled together from
various code examples on the web. I hope you like it.

Thanks that is what I was looking for, to bad there isn't a UI or anything for it.

You may have to install a few extra packages via opkg eg: opkg install gst-plugin-audiotestsrc on shr-testing or using the direct address: http://build.shr-project.org/shr-testing/ipk/armv4t/gst-plugin-audiotestsrc_0.10.17-r5_armv4t.ipk Use: gst-inspect audiotestsrc fo more info.

If you are using debian or a derivative I'm sure there is something, how well the gui will work on the phone is anyone's guess.

I mean like playing a tone, the same tone, but at different pitch like 67Hz as an example On Thu, Apr 23, 2009 at 11:17 AM, Nicola Mfb wrote: > 2009/4/23 Adam Jimerson : > > I am looking for a app like the Dog Whistle for the iPhone that allows > you > > to set a pitch and it plays a note at the pitch, I looked in opkg.organd in > > the application page in the wiki and didn't see one like that and was > > wondering if there is one or if it would be a great suggestion for a app > for > > a developer to make? > > If playing notes fits your needs try > http://tg.gstaedtner.net/projects/euphony.html > > Regards > > Nicola > > ___ > Openmoko community mailing list > community@lists.openmoko.org > http://lists.openmoko.org/mailman/listinfo/community > ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
