These opcodes can read, transform and resynthesize ATS analysis files. Please note that you need the ATS application to produce analysis files. From the ATS Reference Manual:
"ATS is a software library of functions for spectral Analysis, Transformation, and Synthesis of sound based on a sinusoidal plus critical-band noise model. A sound in ATS is a symbolic object representing a spectral model that can be sculpted using a variety of transformation functions."
For more information on ATS visit: https://ccrma.stanford.edu/~juan/ATS_manual.html.
ATS analysis files can be produced using the ATS software or the csound utility ATSA
The opcodes for ATS processing are:
ATSinfo: reads data out of the header of an ATS file.
ATSread, ATSreadnz, ATSbufread, ATSinterpread, ATSpartialtap: read data from an ATS file or buffer.
