The Python audio processing suite is a module that contains a variety of convenience functions to process audio signals. It can be used to plot spectral analyses of a song across time and to quickly ascertain encoding quality, but the instrumental goal of this suite is to robustly identify duplicated songs, regardless of which album they were released in, encoding quality, or start time.
Telemeta is a global audio archiving program which introduces useful and secure indexing methods to back up digitized audio files and metadata dictionaries. It is dedicated to backing up any digitized and documented sound from collections of vinyls, magnetic tapes, or audio CDs over a strong database in accordance with many standards. Export functions also encapsulate edited metadata into a compressed file. The object style architecture provides easy developed user-friendly interfaces and a plugin style audio processing.
glfer is a GTK+ application that shows the input signal frequency spectrum in a waterfall display and can also control a transmitter to emit slow-CW (QRSS) signals. The signal to be analyzed can be acquired in real-time from the sound card or can be read from a WAV file. The signal spectrum can be computed using four different spectral estimators. The spectrogram display can be saved as an image; you can choose to save the entire window, or select a rectangular region to save with the mouse.
bbJewel creates a PDF of a cover for the listed MP3 files for the purpose of printing a jewel case insert. It parses each file and extract the title, artist, and length of the recording. It also scans the files for included cover images. You can provide the CD title and the cover image to use on the command line.
ll-plugins is a small collection of LV2 plugins and a host that runs them. All plugins are installed in separate LV2 bundles (except the ones that are closely related, like the math-constant plugins or the mono and stereo versions of the peak meter). The GUIs, for the plugins that have GUIs, are installed in bundles of their own to make it easier for packagers to put them in separate binary packages to avoid Gtk dependencies for the plugins themselves. There are synths, event processors, simple audio and control manipulators and GUI-based plugins.
The Epeios MIDI to XML converter makes it possible to convert binary MIDI files to a format that allows them to be handled effectively with tools like CVS. If you put, using your favorite MIDI sequencer, the CVS '$Id$' tag (or other CVS tags) in the comment tag of the MIDI file, the changes made to this tag by CVS are propagated into the MIDI file.
Intelligent systems would benefit from being able to localize and track sound sources in real life settings. Such a capability can help in localizing a person or an interesting event in the environment, and also provides enhanced processing for other capabilities such as speech recognition. To give this capability to a computing system, the challenge is not only to localize simultaneous sound sources, but to track them over time. The ManyEars project propose a robust sound source localization and tracking method using an array of eight microphones. The method is based on a frequency-domain implementation of a steered beamformer along with a particle filter-based tracking algorithm. Tests on a mobile robot show that the algorithm can localize and track in real-time multiple moving sources of different types over a range of 7 meters. These new capabilities allowed the robot to interact using more natural means with people in real life settings. The ManyEars project provides an easy to use C library for microphone array processing. This includes sound source localisation, tracking, and separation.A tuning Qt GUI is also available for fine tuning the parameters.
mp3plot creates a plot (textual or graphical) of the bitrate distribution of an MP3 file. It displays which proportion of the audio file uses each of the possible bitrates. The plot can serve, for example, to compare an audio source as encoded by different encoders or settings or to display how the chosen (average) bitrate was achieved by the encoder.
Range Software is software for finite element analysis (FEA) in engineering simulations. Its main features are support for Computational Fluid Dynamics (CFD), heat transfer and radiation, linear stress-strain, electro-statics, acoustics, ground water flow, shape optimization, 3D mesh generation, an intuitive GUI, and import and export functionality. The Range Software package contains several tools which helps the user to setup, solve, and analyze the engineering problem.
