Introduction to the Acoustic Diversity Index (ADI)

Over the last three years of maintaining this blog, there’s been a conspicuous absence in the acoustic index toolkit presented so far. Whilst the Bioacoustic Index (BI), Acoustic Complexity Index (ACI) and Normalised Difference Soundscape Index (NDSI) have been introduced and demonstrated across given case studies, the Acoustic Diversity Index (ADI) hasn’t been covered toContinue reading “Introduction to the Acoustic Diversity Index (ADI)”

Two new (relevant) videos

Happy new year everyone! It’s been fairly quiet on here and there’s a second instalment on the AudioMoth deployment at Lady Bay Reef which is currently in the works. This has taken much longer than expected to pull together, largely owing to going out too deep (pardon the pun) and having to rein myself inContinue reading “Two new (relevant) videos”

Lady Bay Reef Survey: Part 1 – tides, seagrass and acoustic complexity

As I’d indicated in my previous post, following the interesting outcome of the October 2022 AudioMoth deployment on Lady Bay reef, I intended to return and deploy a pair of AudioMoths to make further observations of the reef’s underwater environment. You can go back to the previous post if you want a more detailed overviewContinue reading “Lady Bay Reef Survey: Part 1 – tides, seagrass and acoustic complexity”

Preparing big audio files for analysis

If you read my previous post regarding data science workflow, you might recall that I briefly made reference to large audio files and how one might prepare the data for processing and generating useful points of data. One file and one hour: Let’s say I’ve got a single audio file of an hour’s duration. IContinue reading “Preparing big audio files for analysis”

Introduction to NDSI: measuring anthropogenic noise disturbance

If you haven’t checked out the previous post covering ACI and BI, I’d recommend going back to it since it provides an overview of the soundecology package, what indices are and how it all can be put into practice. Last month I presented an introductory case study for the application of the Acoustic Complexity (ACI)Continue reading “Introduction to NDSI: measuring anthropogenic noise disturbance”

An introduction

Hi there! I’m an Adelaide-based sound artist, acoustic ecologist and composer. What am I doing writing about data science you ask? Well, that’s a bit of a convoluted story, but here’s the rundown: my employer (CSIRO) recently set up a Data School program for employees, with a branch of its studies dedicated to data scienceContinue reading “An introduction”
