rdseed 4.8 released

Announcing rdseed version 4.8, available for download from IRIS DMC. You can get more information and download rdseed from the IRIS DMC Software – SEED Tools web page.

rdseed is IRIS DMC’s legacy utility for reading SEED volumes, the FDSN-approved file format for representing and distributing digital seismic data. This utility allows the user to read the contents of the SEED file and convert it to many different output formats, extracting the data, station information, or instrument responses from the file.
