FYI: For the Ker-Chunkers
out there...there is a delay from live
TRBO audio to actual LiveStream output of a few seconds
but Radio Reference is typically about 30 seconds but
has been as short as 15 seconds or as long as 9 minutes.
Meter is now available. Best
audios are in the yellow range, one red bar maximum. More details on how to best use this
The streaming audio levels are fully conditioned to
compensate for the many TRBO
radios with hot audio (piercing local audio at times) which overdrives the
streaming feeds. The audios are set to pass 300-3000
Hz at 0 dB, audio frequencies above and below are attenuated 12 dB and
then all audio above 0 dB is compressed 3:1. With 8 dB
of headroom locally, this limits +9 dB TRBO audio levels to just +3 dB,
well below the limit of the streaming servers. This
hopefully will provide better streaming audio whether listening on
a high fidelity audio system or the crummy speakers in smart
phones. However, over-driven audio will still sound
poor, just not loud. See our AGC
audio test page for more info. Bad TRBO audio is
caused by the users holding their mics or radios improperly
or by their own incorrect audio settings programmed into
their radios. This is a user problem and not a defect
in TRBO audio generally. It has been a user issue for

broadcasts DCI and MARC talkgroups with priority to DCI 1
while scanning Bridge 2 and Comm 1. LiveStream is the better
service as it provides video of a TRBO radios' display which
is rather cool as you can watch the talkgroups, user ID's,
RF and Scan activity, the

The downside is that 30 second commercial as inserted
randomly. Take a look/listen:
LEGACY: As of 12-11-2011, DCI began feeding "Comm 1"
via scan on a single control radio. As soon as the second control radio
comes online, the audio will be split so that the left
channel will be "Comm 1" traffic and the right channel will
be "Group 1" traffic. Both will be available
simultaneously with equal or no priority.
This initial streaming implementation
single TRBO control radio that scans both Talkgroups; "Comm 1" and
"Group 1". "Comm 1" has the priority over
"Group 1" and
the feed is monaural. This is
temporary until a second control radio is available to
dedicate to this streaming project's right audio channel.
The initial audio rumble has been cleaned up and the base
response reduced. The audio level into the RR server
is set fairly low due to the wide dynamic range and many
TRBO radios that are overdriven by their operators.
