I am looking for a logger solution and I want to confirm AudioMoth features.
I have been through the FAQ and specs but its still not super clear. I'll list my requirements below, and if someone can provide some insight to each bullet in their response that would be great. I hope this helps.
Things I have read:
searched some of the forums
What i want to do:
log audio events in certain freq range, pre-process to limit audio frequencies recorded (my guess: yes)
discard low noise periods, ie record on sound detection (my guess: no)
only listen for certain noise events, eg DB level, freq params.
access SD card data without removal of card. (my guess: no)
pass events through to another device like rasp-pi, or send compressed audio, or only events which are detected over cellular to server.
If you can let me know, both in terms of current capability and any future release plans that would be great.
Thanks in advance. Nick
Hi Nick, The hardware is capable of all these things but you would need some custom firmware to support all of them. The current default firmware is a scheduled recorder which allows you to set recording parameters and a recording schedule. The firmware is open and there is a low-level library that takes care of all the device specific details so it would really just need the application specific code that needs updating. We've done a number of custom deployments with updated firmware (including gunshot and bat detection, and connection to additional peripherals such as radio modules and GPS). The firmware is written in C which is relatively low-level so you'd need to find someone with these skills, or we can help with custom firmware versions through a consultancy project. Alex
