Intelligent Audio Capture (IAC)

Intelligent Audio Capture, or IAC, provides the ability to record to your PC hard disk the audio normally

heard from your scanners speaker or earphones. These audio files can then be played back using any PC

media file application such as iTunes or Windows Media Player. IAC is intelligent in that it records

audio in “streams”. Each stream is a continuous audio recording of each channel, TGID or search hit

that has been active during the recording session. ScanControl can currently accommodate up to 100

parallel active streams at one time. IAC also drops out any “dead air”, time when there is no activity on

a particular channel, TGID or search hit. This means the final recording is a condensed, continuous

stream of a single channel, TGID or search hit for the entire time the recording session is active. Of

course, the scanner can only receive one channel, TGID or search hit at a time so the audio streams will

be made up of only the audio segments, called snippets, that are actually received by the radio. See the

diagram below: Each snippet represents a slice of time when the channel has gone active during a

scanning / search session. If the radio stops on that time slice then IAC records that audio and places it

in the file for that channel / TGID / search hit. If the radio does not stop on a particular channel / TGID /

search hit because it is receiving another one, (e.g. snippet5 vs snippet2, snippet7 vs snippet1) then, of

course, that piece of audio is never received so it cannot be recorded. The grey snippets below represent

times when the channel / TGID / search hit went active but was not recorded because the radio was

“listening” on another channel / TGID / search hit.

1. Audio From Your Scanner – The scanners that ScanControl supports have different methods of

transferring the received audio to the PC. The table below shows each model ScanControl

supports and the recommended way to connect the scanner to your PC’s sound card. Please note
