The Common Pipeline Library provides a highly robust set of functions for manipulating signals and images. It is primarily intended for the building of VLT instrument pipelines, but is also useful for generic data handling. It includes a number of useful low-level data types, medium-level data access methods, standard implementations of commonly-used signal processing and data reduction tasks, and dynamic loading of "recipes" for data processing.

IIR is a C++ library that implements fast IIR filters: bandpass, bandstop, lowpass, and highpass. These can be designed using popular analogue filter functions such as Butterworth, Bessel, Chebyshev, Elliptic, Legendre, and pole placement. Creation of a complete filter requires only a single command and filtering is performed with a single function taking a sample and returning its result instantly. The library is template-based and avoids new/mallocs throughout. This library has been adapted form Vinnie Falco's original work and has been converted to run on Unix systems and turned into a realtime causal filter.

Jipes is a Java library that allows you to efficiently compute audio features. Possible uses for these features are general music information retrieval (MIR) applications or, more specifically, personal music software. Unlike many other digital signal processing (DSP) libraries or frameworks, Jipes is not meant for real time processing of a single audio stream that is manipulated and eventually played back. Instead, it focuses on efficiently executing mutiple processing pipelines that transform a signal into a feature or feature set. Since Jipes focuses on features instead of the raw, untyped signal streams, it supports rich types to be used, where other frameworks only offer arrays of raw data. Also, by using Java generics, many core interfaces and classes can be typed to whatever class you see fit for the purpose. However, Jipes also comes with useful pre-defined types and support for raw arrays.

METAXPON ("Metachron" in Greek letters) is a small and fast audio DSP library for time-scale manipulation of 16-bit integer or 32-bit floating point stereo audio data streams. It employs a rigid phase-locked vocoder with dedicated transient detection and processing, and can work in real-time or non-real-time. Four editions are included - a portable edition and three x86 editions. The portable edition can be built with any ANSI C compiler and is OS- and architecture-independent. The three x86 editions are written in assembly using the FPU, 3DNow!, and SSE instruction sets, respectively, with automatic selection between them depending on the CPU capabilities. They can be compiled with MASM, JWASM, or NASM, producing libraries of object files in 8 formats.

SynScope is an offline visualization and alignment tool for time-varying signals acquired from multiple sources that may differ in offset and/or sample rate. SynScope allows you to define reference points that correspond to identical events between source pairs. It then estimates the offset and resample rate to link these sources. It maps sample time from one source to the other via a link equation. Signal alignment can be inspected with synchronous visualization or resampling. With synchronous visualization, linked signals scroll together according to the link relation. With resampling, linked signals are resampled to the highest sample rate and offset-compensated.
