I thought HRD only controlled certain radios that actually had to be connected
to the host computer via a series or USB port? Or is the ability to go to other
web sites and stream audio from them some undocumented feature I missed? I'll
have to check that out? Thanks.

The $40 program provides an SWL GUI for the same functionality as
Icecast or iTunes radio, etc.

Uh, yeah. Maybe you would benefit from a visit to the HRD web site at the link
above. It's a control program for Amateur Radios with computer control
capabilities. It's a great program with a lot of functionality. Just check out
the site, really. That should make things clear to you.

To run HRD. I'm already aware of it. People who refer to their computers
as if they were automobiles use it. I am running my ham radio station on
Puppy Linux and fldigi for control and soundcard modes. My computer is
an "Everex 2500", which is a little tiny low powered VIA C7D-based
system that WalMart tried selling back in 2008 or so. I bought one.
Microsoft wants $150 for an OS on a $150 computer. Screw that.

Did I mention that this computer idles at around 25 Watts? Less than
most notebooks?

Skype. It's commonly used to deliver the audio portion of HRD (Ham
Radio Deluxe). Install the remote end with your favorite operating
system and set Skype to auto-answer any incoming calls from your
account. As soon as you connect, you get audio, with fairly low
latency.

If you want to roll your own, there's:
http://www.speakfreely.org

There's also:
http://umediaserver.net/umediaserver/download.html
There are plenty of other streaming audio apps available. However, be
careful as many of them are designed for streaming music or video, and
therefore have enormous latency. I vaguely recall my adventure with
Microsloth Media Encoder 9 and it's 45 second delay.

If you want multiple channels of audio, better bandwidth, or have some
exotic requirements, you'll need to supply more detail.

Doesn't skype not support point to point? i.e. you couldn't do it from
192.168.1.10 to 192.168.1.20 on a private network. I thought skype
always needs to through the master skype resolver (to do a sort of
dynamic dns function)

Yes, and they have all sorts of other features tailored for that kind of
application.

All I was looking for was a "virtual audio cable" of some sort. (yes, I
know that VAC is actually something else)

No, just that kind of simple thing.. send 3kHz BW audio from one PC to
another, preferably with an app that is available for all 3 platforms
(Win, Mac, *nix)

Something that has a command line like:
sendaudio -i {input audio source} -o 192.168.1.1
recvaudio -i 192.168.1.1 -o {output audio device}

would make me happy.

Simplecast.

And it's free, or used to be, if you only need 4 hours at a time. (I
own a paid for copy for use in MPLS for extended emergency rebroadcasts
of nets.) I and a ham in Maine used to use it to distribute the weekend
"432 and Above EME Net". He had minimal bandwidth, I had enough and a
Shoutcast (Icecast) server and the net was always less than 4 hours. He
connected to me as the stream input and the listeners connected to my site.

Thanks to Shoutcast allowing their system to effectively be cloned they
made solutions like mine possible. They even allow these systems to
respond as "Shoutcast" when queried.

True. If you're not connected to the internet, Skype will not work.
The connection needs to be established via the distributed Skype
directory server system. You cannot easily bypass this to connect to
any random IP address or to your isolated LAN.

If you really want to do that, perhaps a simple G.711 VoIP client
would be sufficient.

If you want to roll your own, there's:

Yes.. of course there's that "end of life announcement" from 2004.

Still works fine for me. Eventually, Microsoft will trample on some
obscure function and declare anything that then fails as legacy and
unsupported. Until that happens, it still works. Having the source
code is also very handy. SpeakFreely has been the basis of several
VoIP applications.

I suppose that if it works well enough, one can keep using it forever
(gosh, I've got plenty of software from the 90s that I keep using)

I'm still running a Xenix 2.3.2 server from about 1988. It should
continue to function until the hard disk quits. I've been waiting for
that to fail for at least 10 years.

All I was looking for was a "virtual audio cable" of some sort. (yes, I

Virtue and virtual are their own punishments.

recvaudio -i 192.168.1.1 -o {output audio device}

VLC will encode via an RTSP (real time streaming protocol) container
using RTP (real time transport protocol).

This looks like the magic incantations:
http://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples#RTSP_live_streaming

Server:
% vlc -vvv input_stream --sout '#rtp{dst=192.168.0.12,port=1234,sdp=rtsp://server.example.org:8080/test.sdp}'

client:

Mo
http://wiki.videolan.org/Documentation:Streaming_HowTo/Advanced_Streaming_Using_the_Command_Line
http://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples

Watch out for the screaming media features versus OS list.:
http://www.videolan.org/streaming-features.html

I must admit that I've never tried using VLC for encoding. If I have
time, I'll give it a try. Otherwise, good luck.

being Linux doesn't disqualify it, but having no support for other OSes
sort of does..

At least it has a command line interface (useful for the remote end,
which is a small Linux box) (bearing in mind the author's warning:

Those options are useful for quick launch (at least for me ;),
but I don't think it's a good idea to use them (they might be buggy),
in the future I may use standard GNU getopt, but for the moment
please use the graphic interface instead.


And it has a variety of flavors. And it might be possible to compile it
to run under OS-X or windows (not in emulation or VM, but using a
useful library)

The real gripe I have is that the data format isn't described anywhere
(at least not that google can find). reading through the source code
finds stuff about headers, stream sync, etc. but there's no obvious
description of what the UDP/TCP packets look like. In fact, there's no
comments in the source code, for the most part.

So if you DID want to write your own endpoint, it would be mighty tough.

I'm not sure what you mean with data format, but I assume you are
talking about the audio stream. IHU is just a simple interface to
Speex, http://www.speex.org/, and that is a free audio compressing
codec, at least free in the sense of BSD License.

The documentation for Speex is rather comprehensive, and it covers the
RTP format and the API.

Hmm.. Appendix C of the Speex doc does provide a RTP example. However,
IHU doesn't say anywhere that this is what it does (it does say it uses
speex for compression). It's also not clear that IHU is actually using
RTP frames. It seems that IHU has its own homegrown packet format:
(in packet.cpp)

ARCHITECTURE OF THE PACKET
*
* A IHU packet consists of 2 parts:
* 1) Header
* 2) Data
*
* THE HEADER
*
* THe header is made up of 3 parts:
*
* a) SYNC Pattern (3 bytes)
* The pattern consists of the fixed ASCII string: "IHU"
*
* b) Packet SIZE (1 byte): unsigned char that contains
* the size of the packet (min size 5, max size 256)
*
* c) INFO data (1 byte)
* It contains those informations (in order):
* - OBSOLETE: still used for bakward compatibility (versions 0.6.x)
* Speex mode (3 bits). It can be:
* IHU_INFO_MODE_ULTRAWIDE
* IHU_INFO_MODE_WIDE
* IHU_INFO_MODE_NARROW
* - Packet type (5 bits). It can be:
* IHU_INFO_RESET 0x0
* IHU_INFO_INIT 0x1
* IHU_INFO_AUDIO 0x2
* IHU_INFO_CRYPTED_AUDIO 0x3
* IHU_INFO_KEY_REQUEST 0x4
* IHU_INFO_NEW_KEY 0x5
* IHU_INFO_ANSWER 0x6
* IHU_INFO_CLOSE 0x7
* IHU_INFO_REFUSE 0x8
* IHU_INFO_RING 0x3f
* IHU_INFO_RING_REPLY 0x3e
*
* d) Data LENGTH (1 byte): unsigned char that contains
* the size of the following DATA part (min 0, max 250)
*
* THE DATA
*
* This part of the packet is of variable size (min 0, max 250 bytes)
* and it contains the data to be trasmitted.
* It can be absent (if the packet doesn't need to transmit any data)
* or, can be audio data or keys for encpryption.
* The type of data transmitted is specified in the INFO header
*
*/


anyway.. the point is that while IHU probably works just fine, it's like
a lot of other undocumented utilities out the it works for what it's
original author intended, and if you want to use it as a basis for
software that you'd write, it's great.


However, my whole question was really to see if some simple
off-the-shelf multiplatform already existed. (i.e. I'd rather spend my
time doing things OTHER than writing audio transport code)

You are probably right. I've used IHU to see if Speex was good enough to
use as an audiolink. I didn't scrutinize the source code. I am planning
to establish a link between my noisy home (Stockholm) and my
summerhouse. Anyhow that good suitable audiolink software has yet to be
written ;)

Sure it has. Look up SVXLINK. It was intended to link a repeater with remote
sites, but you don't actually need to have a radio on either end. It has full
rig control with a serial interface, although one ham here built a USB one
and I believe it interfaces to commercial ones.

It has remote receiver support with voting if there is more than one,
remote transmitter support and a multiuser Echolink client.

It even has the capability to be controlled via DTMF tones built in.

summerhouse. Anyhow that good suitable audiolink software has yet to be
written ;)

Sure it has. Look up SVXLINK. It was intended to link a repeater with remote
sites, but you don't actually need to have a radio on either end. It has full
rig control with a serial interface, although one ham here built a USB one
and I believe it interfaces to commercial ones.

It has remote receiver support with voting if there is more than one,
remote transmitter support and a multiuser Echolink client.

It even has the capability to be controlled via DTMF tones built in.

The SVXLINK project is an intresting one if I want to do FM and or
ECHOLINK - repeater stuff. If I just want an an audiostream then
it's i.m.h.o just to bloated with these DTMF, CTCSS .....

Bloat is relative. It's a reasonably small program that runs under Linux,
you probably could wedge it with the extras turned off onto an old router.

Gone are the days that speak freely was available, and you could run
remote audio pickups via piping the audio via ssh.

(sendprogram) | ssh computer (receiveprogam)

Worked well for me to pipe a receiver in Jerusalem via frame relay to a
remote speaker in Tel Aviv. This used 8k bits per second (plus overhead)
of a 64k bits per second line.
