What is a SAC file

SAC files mostly belong to SAC. SAC files are used mainly for storing seismic data. An SAC file from the Seismic Analysis Code package holds time series waveform records along with a header that contains instrument and timing information.
These files were designed for seismological analysis, but the same extension can be used in other specialized fields.
Usage examples include:

Seismic Data: Contains earthquake or vibration records. Check details at IRIS SAC download.

Scientific Records: Some files carry mass spectrometer or accounting data.

Specialized Archives: A few files are game scene or configuration files.

The primary function remains the handling of seismogram data.
