By VOX I mean software that will only trip when a human voice
is recieved. I have a hardware unit, but software would be
a lot more usefull.

Hi Terry,

VOX is a key feature of RecAll Pro (and the standard RecAll program) found at www.sagebrush.com The software allows for various configuration options of VOX, too.

It's an excellent, easy to use program that's very useful for scanner enthusiasts, DXers, and the like. In fact, RecAll Pro is the basis of my hard drive recording techniques article in February's Monitoring Times magazine.

I don't mention the VOX feature in my article, but other capabilities are discussed. I particularly like the running time/date stamp in RecAll Pro that allows it to be set to UTC.

Is a true VOX that detects human speech, or a
"normal" level switch that will trigger on any signal
above some preset level?
Terry

I downloaded and installed RecAll Pro.
It has what appears to be a standard
level sensing VOX switch. Unless I am
missing something.

One implementation, in hardware, can be seen at:

This is a very usefull device, but I am looking
for a way to do it in software.

Subject: Voice detection software?

Lou,

Voice squelches for HF are typically "syllabic squelches". They do not
react on noise but on the pattern of the signal. Simple hardware based
ones
try to detect the presence of voice (low frequency syllabic variations
associated with voice). Although not perfect, these types of squelch
circuits are fairly common on commercial and military HF equipment.

Noise based squelches are practically unusable on HF as they are
triggered
by any random noise... and as we all know, HF-AM/SSB sure isn't FM ;-)

However, I agree that it would be an interesting project if someone
created
a software-based syllabic squelch application that can be used with any
radio... any takers? ;-)

Search up Scanner Recorder or ScanRec.

It's a freebie and works great,.

Please read the thread.
I am not after a level sensing VOX,
I am after a program that only responds
to human voice.
ScanRec is a great program.
And on a FM comm system,
with decent radio squelch performs
very nicely.
But I am after a Voice Operated as
opposed to signal operated squelch.
