The Racelogic ADAS Audio Sensor (RLADAS-AS-V1) has a CAN output which is present on the 5-way connector output.
Little Endian (Intel) Format
Data format: Little endian (Intel)
Baud rate: 500 kbit/s
You can find the Audio Sensor's CAN database (.DBC) file with the default CAN configuration here.

*Default Identifiers. The identifier values can be changed using the configuration software.
- 16-bit unsigned - Estimated time since the start of the sound in ms.
- 16-bit unsigned - Signal strength estimate (strongest signal if there are multiple active signals).
- 16-bit unsigned - Frequency of the strongest signal in Hz.
- For the flags bytes:
bit 0 = channel 1 detected
bit 1 = channel 2 detected
bit 2 = channel 3 detected
bit 3 = channel 4 detected
bit 7 = master trigger signal
NOTE
Bits 0-3 in the flags byte reflect the current status of the channels. In the event of either a signal that lasts less than the minimum detection time or not all signals being detected in ALL frequencies mode it is possible for the individual channel flags to be active but for the system not to trigger.
The detection signal level will be the highest level seen since the start of the trigger.
The detection frequency will be the frequency of the highest signal level seen since the start of the trigger.
If a trigger event lasts less than 100 ms then the output packets indicating a trigger will be extended to a minimum of 100 ms with the final signal values preserved and the time increasing.
