Phonological Vocoding Using Artificial Neural Networks

We investigate a vocoder based on artificial neural networks using a phonological speech representation. Speech decomposition is based on the phonological encoders, realised as neural network classifiers, that are trained for a particular language. The spe ...

Implementing super-efficient FFTs in Altera FPGAs

Pierre-André Farine, Cyril Botteron, Jérôme Leclère

In this article, an alternative method is proposed to compute a fast Fourier transform (FFT) on Altera FPGAs. This method is using the Altera FFT intellectual property (IP) core, but it is more efficient than the direct use of the Altera FFT IP core, in th ...

ECMA-407: New Approaches to 3D Audio Content Data Rate Reduction with RVC-CAL

Marco Mattavelli, Claudio Paolo Alberti, Junaid Jameel Ahmad

Inverse problems have only been known in spatial audio for a very short time; their only solution, called "inverse coding" in literature, is essentially based on time-level modeling. Inverse problems, however, unlike parametric coding, require only an init ...

ECMA-407: A New 3D audio codec implementation up to NHK 22.2

Marco Mattavelli, Claudio Paolo Alberti, Junaid Jameel Ahmad

ECMA-407, the first 3D audio standard worldwide, introduces a new concept of static models to lower bitrate coding, which may be equally applied with channels, channels and objects and Higher Order Ambisonics (HOA). Static models may either operate in time ...

Exploring MPEG HEVC decoder parallelism for the efficient porting onto many-core platforms

Marco Mattavelli, Simone Casale Brunet, Claudio Paolo Alberti, Damien Jack De Saint Jorre

MPEG High Efficient Video Coding (HEVC) is likely to emerge as the video coding standard for HD and Ultra-HD TV resolutions. The two elements that push HEVC beyond the previous standards are a higher compression efficiency of about a factor of two, and the ...

Automated design flow for coarse-grained reconfigurable platforms: An RVC-CAL multi-standard decoder use-case

Marco Mattavelli, Simone Casale Brunet, Endri Bezati

Specialized hardware infrastructures for efficient multi-application runtime reconfigurable platforms require to address several issues. The higher is the system complexity, the more error prone and time consuming is the entire design flow. Moreover, syste ...

Towards highest spectral efficiency: Optical sinc-shaped Nyquist pulses generation from rectangular frequency comb

Luc Thévenaz, Camille Sophie Brès, Marcelo Alfonso Soto Hernandez, Mohammad Amin Shoaie, Mohammad Mehdi Alem Karladani

In this paper, we review a method to produce optical sinc-shaped Nyquist pulses with unprecedented quality. The method is based on the synthesis of a rectangular shaped and phase-locked frequency comb from a combination of intensity modulators. The result ...

Characterizing communication behavior of dataflow programs using trace analysis

Marco Mattavelli, Simone Casale Brunet

This paper investigates the relationship between two ways of analyzing streaming systems: trace analysis for dataflow programs with firing, and network calculus for network flows. While the former focuses on the structure of the dataflow computation while ...
