Squawk: A Graphical Software for Spectral Audio Processing

نویسنده

  • Ryoho Kobayashi
چکیده

This paper describes the design and development of new graphical software for spectral audio processing. There are three phases to accomplish the audio processing. First, spectrograms are generated from an input audio signal using Short-Time Fourier Transform (STFT) analysis, and the sonogram image is continually shifting from right to left. Secondly, the sonogram is transformed by placing prepared effect objects such as panning, compressor and delay, on the streaming spectrogram. These effect objects provide various transformations to specific range of frequencies, then, by combining them, powerful effects will be produced. Thirdly, a transformed audio signal is generated from the edited sonogram by using overlap-add resynthesis or oscillator bank resynthesis technique.

Combining Visual and Textual Representations for Flexible Interactive Audio Signal Processing

Interactive computer music systems pose new challenges for audio software design. In particular, there is a need for flexible run-time reconfiguration for interactive signal processing. A new version of Aura offers a graphical editor for building fixed graphs of unit generators. These graphs, called instruments, can then be instantiated, patched, and reconfigured freely at run time. This approa...

Gui Front-end for Spectral Warping

This paper describes a software tool developed in the Java language to facilitate time and frequency warping of audio spectra. The application utilises the Java Advanced Image Processing (AIP) API which contains classes for image manipulation and, in particular, for non-linear warping using polynomial transformations. Warping of spectral representations is fundamental to sound processing techni...
