Audio Signal Processing

In signal processing, cross-correlation is a measure of similarity of two waveforms as a function of a time-lag applied to one of them. This is also known as a sliding dot product or inner-product. It is commonly used to search a long duration signal for a shorter, known feature. It also has... Platforms: Matlab

The script uses only one transmission symbol per frequency hop. Platforms: Matlab

Sfront project compiles MPEG 4 Structured Audio (MP4-SA) bitstreams into efficient C programs that generate audio when executed. MP4-SA is a standard for normative algorithmic sound, that combines an audio signal processing language (SAOL) with score languages (SASL, and the legacy MIDI File... Platforms: *nix

Hanso Tagger is a must audio tag processing tool for the keen music listener created as a convenient solution for organizing vast music collections. The program was thought out as a complex, yet, easy to use, tagging tool to help you avoid misplacing music files or having a hard time managing... Platforms: Windows, Windows 7

An audio plug-in suitable for a wide range of professional music production uses that implements an audio signal envelope adjustment algorithm that reacts on transients rather than on a signals loudness level. This algorithm allows you to adjust volume of attack and sustain stages of any sounds... Platforms: Mac

A mastering compressor plug-in for professional audio and sound production applications. Polysquasher was designed with a main goal: to be transparent. Transparent compression action is a cornerstone for any mastering compressor. Transparency of audio signal processing is necessary to preserve... Platforms: Mac

An audio signal compressor plug-in for professional audio production applications. The characteristic feature of this compressor is its ability to produce 'slim' and 'slick' sounding compression, with intelligibility enhancement effect. Such result is achieved by compressors timing function that... Platforms: Mac

A software audio effect processor that enhances an audio signal, producing a fuller, livelier, bigger sound. Input signals are split into as many as 20 individual voices, each of which are detuned, placed around the stereo panorama, and recombined with stunning results. Flexible controls mean...

Matsig is an object-oriented signal class library (Toolbox in MATLAB lingo) for MATLAB 6.5 and later. It implements a signal class, simplifying operations and manipulations common in audio signal processing and speech processing. Platforms: Windows, Mac, BSD, Linux

The objective of SPUC is to provide the Digital Communications Systems Designer or DSP Algorithm designer with simple, efficient and reusable DSP building block objects written in C++. Platforms: Windows, Mac, Linux

STK (Seismic Tool Kit) is a tool for seismic signal processing in graphical interface: various filters, spectral analysis, polarization, time-frequency, Hilbert transform, instrumental response...etc. Signals processed in STK must be in SAC format. Platforms: *nix

This is a crude attempt at quasi-realtime signal processing using the PC sound card as an analogue data acquisition device. The cardiogram signal is generated by a Polar heart rate monitor strap and transmitted wirelessly to a receiver connect to the PC microphone. See here for the physical... Platforms: Matlab

The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is implemented in N log2 Nadditions and subtractions. Data... Platforms: Matlab

Lab 4a:The primary goal of the first lab is to familiarize you with using Simulink so that in the next lab you can use Simulink to program a DSP. Here are three specific goals for this lab:d-deD? Learn basic Simulink commands and syntax, including the help system.d-deD? Learn to write and edit... Platforms: Matlab

Until recently, Base station antennas have been omnidirectional or sectored. This can be regarded as a waste of power as most of it will be radiated in other directions than toward the user. In addition, the power radiated in other directions will be experienced as interference by other... Platforms: Matlab
