Marsyas is an open source software framework for audio analysis, synthesis and retrieval with specific emphasis on Music Information Retrieval. It is developed by an international team of programmers and researchers led by George Tzanetakis. In MIREX 2010 the Marsyas team participated in the following tasks: Audio Classical Composer Identification, Audio Genre Classification (Latin and Mixed), ...

For very low bit rate audio coding applications in mobile communications or on the internet, parametric audio coding has evolved as a technique complementing the more traditional approaches. These are transform codecs originally designed for achieving CDlike quality on one hand, and specialized speech codecs on the other hand. Both of these techniques usually represent the audio signal waveform...

This paper presents the first detailed mathematical analysis of the ripple compensation technique for reducing audio distortion in a class-D amplifier with negative feedback. The amplifier converts a relatively low-frequency audio signal to a high-frequency train of rectangular pulses whose widths are slowly modulated according to the audio signal (pulse-width modulation, PWM). Distortion manif...

The vector representations of fixed dimensionality for words (in text) offered by Word2Vec have been shown to be very useful in many application scenarios, in particular due to the semantic information they carry. This paper proposes a parallel version, the Audio Word2Vec. It offers the vector representations of fixed dimensionality for variable-length audio segments. These vector representatio...

Designers of quality audio equipment have long recognized the value of a low noise gain block with “audiophile performance”. The LM833 is such a device: a dual operational amplifier with excellent audio specifications. The LM833 features low input noise voltage typical), large gain-bandwidth product (15 MHz), high slew rate (7V/μSec), low THD (0.002% 20 Hz-20 kHz), and unity gain stability. Thi...

A supervised learning approach to ambience extraction from onechannel audio signals is presented. The extracted ambient signals are applied for the blind upmixing of musical audio recordings to surround sound formats. The input signal is processed by means of short-term spectral attenuation. The spectral weights are computed using a low-level feature extraction process and a neural network regr...

On the web, searching for sounds is usually limited to text queries. This requires adding textual descriptions to each audio file, which is indexed effectively as a text document. Recent developments in browser technologies allow developers to access the audio input or microphone of the computer, enabling Query by Example (QbE) applications. We present a demonstration system that allows users t...

We present a framework for the analysis and synthesis of acoustical in struments based on data driven probabilistic inference modeling Audio time series and boundary conditions of a played instrument are recorded and the non linear mapping from the control data into the audio space is inferred using the general inference framework of Cluster Weighted Modeling The resulting model is used for rea...
