Phone sounds. Everything but the phone. Old style US dialtones and modulated ringbacks - modern dial tones and ringbacks - SIT tones - an outpulse sequence (reminds me of the one from Pink Floyd the Wall) - off the hook warning sound - UK style ringback - engaged line tones - all created on SoundForge 8's Frequency Modulator ... oh yeah and they're squeaky clean... no static or grounding hums.

    The old American dial and engaged tones are about as close as one can get to the original by using simple, computer-generated tones.

    The old American ring appears to be similar to the old Metropolitan ring, but of course it would be practically impossible to re-create the original with software.

    The new precise-tone dial tone is perfect, but I don't see why an interrupted version was included - there's no time that this ever was heard, at least in America. The busy signal is just 480hz + 620hz at 500ms on and off.

    The American ring signal is spot-on, both in timing and pitch.

    The British ring is also perfect, both in timing and pitch.

    The CCITT R1 MF tones were incorrect in timing - the actual timing is 100ms on and off for the KP signal, and 70ms on and off for the rest. The number keypulsed was KP02490510ST, which is an odd number to choose as it is 8 digits and isn't an actual telephone number. The 480hz tone following the sequence is completely irrelevant - I don't see why it's there, as it has no meaning whatsoever.

    The SIT tones following are fine, and I believe are the ones used when a number is disconnected. That may be useful to play for telemarketers!

    The American reorder signal is fine in timing, but completely wrong in pitch - it appears to have been generated by modulation, when the actual tone is just meant to be 480 hz + 620 hz.

    The off-hook signal is correct both in tone and pitch, although a subscriber would never hear this signal without some level of distortion, as it is shown here.

    The howler tone is well done, but is of course not perfectly accurate due tot he fact that this was originally created by mechanical equipment. The timing is also not precisely close to the original sound.

    As you can see, I know a thing or two about telephone sounds. I'm just trying to help, so forgive me if I come across as snobbish at all.

    That off hook howler reminded me of my childhood when I left the phone off the hook to listen to that. (we didn't have a phonograph) Great Job as always

    As always, Freqman, you come through with the perfect sound.

    It's an almost 100% rendition of UK tones - the only two slight imperfections are the off-hook wailer which is now much higher in pitch, and the A-E-G# error tone, which has a slightly longer duration for each of the tones than you've synthesised.

    Other than that, pretty much spot on :) perfect usage of the freq gen... Now for your next trick, the DTMF tones. ;)
