Extensions to Convolution for Generalized Cross-Synthesis

  title={Extensions to Convolution for Generalized Cross-Synthesis},
  author={Christiane Donahue},
Cross-synthesis is the process of blending two or more audio signals to produce a hybrid signal with timbral characteristics of the originals. There are a number of methods to perform cross-synthesis of digital audio including but not limited to vocoding, phase vocoding and convolution. Convolution is a common approach to perform cross-synthesis on arbitrary sound files but the process suffers from inflexibility. Having no control over the process itself, a musician interested in convolutional… 
Headphone Filtering in Spectral Domain
This study will move in the direction of establishing a standard that can be used as reference for measuring headphone performance, and to find out analytically, if they are preferred with the implemented filter sets over their default response.
Digital Forensic Analysis of Files Using Deep Learning
This paper investigated the existing forensic approaches to identify the file type and developed a new approach based on deep learning and overcome previous approaches' limitations, which will provide a model able to predict corrupted files.


Extended Convolution Techniques for Cross-Synthesis
This work introduces novel extensions to the discrete convolution operation to give musicians more control over the process and analyzes the implications of discrete Convolution and its extensions on acoustic features using a curated dataset of heterogeneous sounds.

In this work we propose a new physical modeling technique whereby a waveguide structure is replaced by a low latency convolution operation with an impulse response that is either measured, modified,
A linear filtering approach to the computation of discrete Fourier transform
It is shown that the discrete equivalent of a chirp filter is needed to implement the computation of the discrete Fourier transform (DFT) as a linear filtering process, and that use of the conventional FFT permits the computations in a time proportional to N \log_{2} N for any N.

A general methodology for audio segmentation based on multiple temporal features combined with automatic or semi-automatic annotation is proposed and a prototype audio browsing and annotation tool based on segmentation combined with existing classification techniques was implemented.
The chirp z-transform algorithm and its application
Applications discussed include: enhancement of poles in spectral analysis, high resolution narrow-band frequency analysis, interpolation of band-limited waveforms, and the conversion of a base 2 fast Fourier transform program into an arbitrary radix fast Fouriers transform program.
Efficient Convolution without Input/Output Delay
A hybrid convolution method is proposed, which combines direct- form and block FFT processing, and the result is a zero-delay convolver that performs significantly better than direct-form methods.
High-speed convolution and correlation
A procedure for synthesizing and analyzing Fourier series for discrete periodic complex functions and computation times are proportional to log 2sub 2 as expressed in Eq.
