Software for spectral Analysis, Editing, and synthesis
نویسنده
چکیده
This paper describes the design and development of new software for spectral analysis, editing and resynthesis. Analysis is accomplished using a variation of the traditional McAulay-Quatieri technique of peak interpolation and partial tracking. Linear prediction of the partial amplitudes and frequencies is used to determine the best continuations for sinusoidal tracks. A high performance user interface supports flexible selection and immediate manipulation of analysis data, cut and paste, and unlimited undo/redo. Hundreds of simultaneous partials can be synthesized in real-time and documents may contain thousands of individual partials dispersed in time without degrading performance. A variety of standard file formats are supported for the import and export of analysis data.

A series of 2-methylthio-1,4-dihydropyrimidine derivatives (II) were synthesized in good yields by alkylation of 1,2,3,4-tetrahydropyrimidines (I) with methyl iodide in the presence of pyridine. Their structures were confirmed by elemental analysis, IR and 1H NMR spectra. The compounds were tested for analgesic activity by acetic acid induced writhing method. Compounds IIh, IIe, IIk and IIl sho...
