3 Data Issues on Soundscape Ecology Big Data Data volume for one site soundscape recording in one year: (16 bits * 44.1 KHz * 2 channels * 60 seconds * 5 minutes * 2 / hour * 24 hours * 365 days/hours) / (8 bits/byte ) * 10-6 = 927 GB ~ 1 TB Many sites and many countries in long term:??? PB??? ZB How to manage, share, and utilize? Big Science Hampton, S. E., et al. (2013). Big data and the future of ecology.

4 2014 Asian Soundscape Workshop Malaysia, Philippines, Taiwan, Thailand, and Vietnam Sharing experiences and having consensus on open data Developing a soundscape monitoring protocol for Asia Collaboration on long-term joint monitoring of Asian soundscape Creating Big Open Linked Data (BOLD) environment Fostering soundscape research, conservation, education in Asia Initiating Soundscape Alliance in Asia

5 Asian Soundscape /11/17-20 Asian Soundscape Workshop, Lienhuachih Research Center, TFRI, Taiwan

6 Exploring soundscape by date and time of different sites

7 Browsing soundscape by map

8 Forest soundscape in Sanyi Township, Miaoli County, Taiwan

9 Listening to and browsing metadata of a soundscape recording

10 Exploring the components of soundscape by spectrogram Biophone: bird song Anthrophone: traffic

11 Selecting range of frequency band and identifying soundscape components

12 Comparing soundscape from different sites

13 Forest soundscape from Taiwan, Vietnam, and Thailand

14 Analyzing Soundscape Computing 5 soundscape indices in R Data: 123 WAV files (51 MB each, 6GB in total) CPU: Intel Xeon 2.0GHz 6 Cores x 2 (20 threads used for computing; 88% used) Memory: 24GB (87% used) Time: 3, seconds
