PyPAM based data processing
The mbari-pbp package allows to process ocean audio data archives to daily analysis products of hybrid millidecade spectra using PyPAM.
Status: Functional version, including support for cloud based processing.
- JSON generation of timekeeping with indication of start and duration of recognized sound files
- Audio file processing
- Frequency and psd array output
- Concatenation of processed 1-minute segments for daily product
- Calibration with given sensitivity file (NetCDF), or flat sensitivity value
- Data products
- NetCDF with metadata
- Summary plot
- Cloud processing
- Inputs can be downloaded from and uploaded to S3
- Inputs can be downloaded from public GCS bucket
- Outputs can be uploaded to GCS
Example plot of a daily hybrid millidecade generated with the
pbp hmb-plot command:
