Detection of transients or attacks for time/frequency resolution switching

Full Title

Speech or audio signals analysis-synthesis techniques for redundancy reduction, e.g. in vocoders; Coding or decoding of speech or audio signals, using source filter models or psychoacoustic analysis (in musical instruments G10H) > using spectral analysis, e.g. transform vocoders or subband vocoders > Blocking, i.e. grouping of samples in time; Choice of analysis windows; Overlap factoring > Detection of transients or attacks for time/frequency resolution switching
