    on my old iphone 3g the high frequency sound apps all worked perfect, but using my new 3gs it sounds muffled and distorted.has anybody else tried these apps using a 3gs and how did it go?

    I love the dog whistle app on my 3G. Nothing like it to gently irritate the loud cursing youths at the next table it's time to move on -- and they don't even know why they want to leave. Love it.

    On my wife's 3GS, however, it sounds as if it's being played on a 1963 tube radio, with car speakers that have been left out in the sun for a few decades. Rattle-y, like. Rough. Even her SMS sound is like that.

    lol cheers for that i can only assume it needs to be optimized then, or the speakers are crap!

    I doubt it's the speakers -- at least, I have not read of any hardware difference there. Software/driver/firmware, perhaps... that's something else to look forward to. Or rumormonger about...

    they made the ringer louder on the 3GS

    and the speakers do tend to 'crack' if you play the sound at full volume - take it down a notch or 2 and it plays like it did before.

    i upgraded to a 3gs from the original phone, kept all the same settings and the other day my wife asked me if i had new alert tones -- the initial alert / ring from the new phone sounds like a speakers blown but then the following tone plays normal -- hope this gets fixed in an update...

    Well I went from a 2G iPod Touch to a 3GS 32GB iPhone, and there is no noticeable sound difference. Maybe this info will help.

    This sounds like a problem with the digital-to-analog conversion that takes the digital representation of the sound and turns it into a voltage signal that drives the speakers. If this is a genuine problem, then I am not impressed - any decent engineer would be aware of the potential for this and eliminate it.

    I doubt it's the DAC. You'd need a fairly low resolution to start hearing imperfections like that. My guess is the speaker is up against some hard component that resonates at some unfortunate frequency.

    it may well be resonance, when i decrease the volume to barely audible it does sound better, other than that it just sounds like a mid range frequency
