Realtime Sampling + internet = phone
Scott Krehbiel
Okay, I have an idea...
What if you were to get an online service, say America On Line, or
something that gives you chat capabilities...
and open a chat line with someone far away,
start a program that takes samples from an audio sampler,
(maybe strips off the low bits - therefore can cram more data per byte
if you tried this real-time)
uuencode this data and send it over the modem, so the other
person's computer could receive it and play the sample??
It could definitely work, in a Ham radio or CB fashion... sending
a sentence, then waiting for the reply. Doing realtime stuff
may be a lot more difficult.
You'd have to have the ability to sample, play samples, uuencode
and decode, and ascii upload.
This could be a real pain if you had three separate programs to do
all this, but are there existing programs for the Amiga to do this
type of thing?? (Maybe even some really nifty term program that
some genius developed could have ALL this stuff?? Nah!)
Maybe a term program and a sampling program, both with an Arexx port.
Arexx could give CLI commands to control the UUencoding and decoding.
Anyone have some ideas?? Term programs with Arexx ports and Arexx
macros?? Sampling programs with Arexx ports??

Well I don't know how and if/when it will be implimented on the Amiga but on
the C4 program "Heaven & Hell on Earth" the guys at MicroSoft were displaying
there 'teleconfrencing' s/w.
Between them and USRobotics (& more than likely others that weren't mentioned)
they have started work on a standard for this sort of protocal for speech & data
transmition across the 'net.
Looked pretty cool, even on the PC ;)..

Hmmm... Sounds like a lot of wasted bandwidth to me.. I don't like the idea
of the net replacing LD phone lines.

Get used to it. Our campus radio just went online this week(WREK). I'm sure
that in another year or so more and more radio stations will do the same.
If you think the net is crowded now, just wait till major financial
institutions come online(i.e. banks). Once that happens, the net is going
to GET HUGE.

In Tuesday's Daily Telegraph there was an article on a company that is going
to sell a system for PC's that will allow two people to use the Internet as a
telephone, so you can to international calls for the price of a local call.
Basically the system used a couple of cards with audio compression chips on
them to grab the speech.
There might be info on the electronic telegraph (http://www.telegraph.co.uk)
but you need Forms :-(

Well.. On the Macintosh we use CuSeeMe (see other thread) and also a prg
that does the sound part of it (forgot the name), which gives you live
sound (continuous, but every now and then a little click if the lines
are slow), and 'live' shocky video. Bidirectional, ja.
Didn't see the MS-DOS thingy on this, but it's not a new idea. I think
Sun/SPARCS also have made a sampled speech version of 'talk' quite some
years ago (err.. I guess Sun did not make it themselves, but it ran on
those machines, and no... I don't have it now)

whereby a PC with a sound card and a microphone and, of course, a TCP/IP
stack can "call" a remote TCP/IP address (also a PC with a sound card and
a microphone) and do real-time bi-directional voice over the TCP/IP link.
Using this protocol, the cost for a unlimited call from the U.S. to say,
Germany would be .... let's see now, multipley by the rate, carry the
zero, --- exactly $0.00.

But what about Arexx on the Amiga?? I bet it wouldn't be too
terribly tough to write links between a term program and a sampler prog.
Does anyone know of a terminal program with Arexx?? How about an audio
sampler program with Arexx?? Hopefully, with macros built into the
term program, you could command the sampler prog and the PD uuencode
command to accomplish this task, on a CB radio type of thing.

That's a waste of bandwidth.

Speech needs about 8kbyte/s without compression and maybe 1kbyte/s
with smart compression. No that far away from most internet connections
although you do not get a guaranteed bandwidth and turnaround time
from IP. That's why we have _telephone_. Digital telephone and Internet
even use the same physical links.
An ultra smart compression could convert the speech to text, send
the text and the other side would use a speech synthesizer.
That's about as efficient as typing in the text without typing and
maybe uses 10Byte/s. Compression based on codebooks for individual
speakers would drop that to less than 1Byte/s on average.

It isn't very feasible at the moment, but in the not so distant future,
with say 64K lines into your home it would be. Of course the net worldwide
would also have to be upgraded by an order of magnitude as well.

Garbage.. Internet costs more than phone and excessive bandwidth waste
will increase the cost of Internet access.
Of course YOU might not pay for it directly, but you still pay for it.

Not where I'm from it doesn't.
I pay a flat fee of 10 UKP + VAT per month plus my local phone calls.
That's much cheaper than a international call.

Right, but what happens when CU-seeme gets a grip? We (read: Ami users)
will be paying for the PC users bandwidth.
It doesn't matter how it's done, at the end of the day international comms will
be via the Net.
Textual, vocal or visual.
