The invention enables rapid omnidirectional navigation of hierarchical networks that contain compressed image information. A user agent advantageously joins units of map information using expanded higher-level map information, responsively to or in anticipation of user navigational actions such as downward level-jumping, lateral navigation, and scaling. The user agent positions lower-level units of map information using reference points which are expanded relative to corresponding higher-level points, reflecting an expansion of available area between levels.

A method of synthesizing audio signals provides outputs of high subjective quality which retain the semblance of natural origin. Unlike frequency scaling methods, the pitch of a signal can be modified independently of the spectrum envelope. A set of candidate input sections is defined based on input transform-domain signal representations. A match-output transform-domain section is formed using the result of a matching process which compares candidate input sections to a reference section. The reference section for this matching process is defined based on one or more previously formed match-output sections. Main-output transform-domain signal representations are formed based on one or more match-output sections, whereby such main-output transform-domain signal representations can be inverse-transformed and combined with the output time-domain signal. This method is referred to as "Transform-Domain Match-Output Extension" (TDMOX). One embodiment of the invention implements block-transform processing using an FFT algorithm.

An electrical process transforms an object electrical signal into a compact time-varying graphical representation whereby study of the time-varying spectral properties of said signal may be efficiently pursued. A time-varying symbol (TVS) includes means for providing first electrical signals representative of the time-varying magnitude spectrum of said object electrical signal, means for generating second electrical signals representative of the continuous variation in position and shape of a single graphical edge as a function of frequency, wherein said continuous variation in position and shape is such that all points inside some closed area within the output image are swept at more than one frequency within some continuous portion of the frequency range covered by said electrical process, and wherein said continuous variation in position and shape is such that no position and shape are repeated at more than one frequency throughout said continuous portion of said frequency range covered, and means for combining said first and second electrical signals into an output electrical signal representative of the weighted superposition of edges over all frequencies.
