OPTIMOD PC
In this scenario, OPTIMOD-PC processes all audio sources to achieve a consistent,
professional sound. No additional sound card is required. The analog input of
OPTIMOD-PC receives the radio station program audio to be streamed. Secondary
playout software, running on the same computer as OPTIMOD-PC, plays commercials
intended only for the stream. This software is configured to use OPTIMOD-PC as its
sound device. When a commercial in the radio station's program audio is to be re-
placed by a different commercial for the stream, the primary playout system starts
the streamed commercial on the secondary playout system and executes
audio_insert.bat
tem executes
audio_norm.bat
In a related scenario, the digital input of OPTIMOD-PC can be used for digital stu-
dios. The .txt script file would be edited to switch the digital input. Because
OPTIMOD-PC has four inputs, one can imagine advanced scenarios where the auto-
mation switches up to four audio sources.
The file "audio_norm.bat" contains:
plink -telnet -P 11101 127.0.0.1 < audio_norm.txt
The file "audio_norm.txt" contains:
111111111 A1PIM Unmute
111111111 W1PIM Mute
disconnect
The file "audio_insert.bat" contains:
plink -telnet 127.0.0.1 < audio_insert.txt
The file "audio_insert.txt" contains:
111111111 W1PIM Unmute

Microsoft Windows Mixer Control API
The 1101 OPTIMOD-PC driver appears to Windows as two standard Windows Direct-
Sound Devices. It appears as four audio devices: two Input/Recording and two Out-
put/Playback. The 8-digit OPTIMOD-PC serial number is appended to the device
names, which is especially useful in systems with multiple cards.
