Open Source Linux Audio Analysis Software - Page 5

This is an audio processing project in a very early stage.

The Audio-Analyzer project is a set of tools for measuring the frequency response, distortion, and quality of audio equipment. It includes test signal generators and spectrum analyzers.

This frontend for ffmpeg batch analyzes audio files for Peak levels, peak and total RMS, and DC offset. Much faster than a typical audio editor with a statistics plugin, which first loads the file while generating a picture, then scans it a second time to find the statistics. This program does it all in one fell swoop, thus half the time. What's more, it was designed specifically for set and forget batch operation. The end product is a text file with the same filename as each audio file, in the same folder.

can be used to restore skipping and jumping or scratched audio CD. Needs to copy tracks multiple times and then using this tool fix broken parts on wav files.

Python Script to process a wave file and transform to movement (key frames) on Blender 2.5. Input: sound file (.wav) Output: Key frames direct into the selected object Work to meshes and bones (location, scale or rotation in any axis)

Audio::DB lets you quickly build and query relational databases of audio collections. It currently supports MySQL and SQL lite databases.

This project aims to classify an MP3 music library into agitation level, and generate playlists of each classified group. By now those groups are: Calm, Medium and Agitated.

Small php script to retrieve, cache and display profile data from the rss feed at http://www.audioscrobbler.com/.

AutoTrans will transpose a Song for you. Choose the old key and the new key, klick the start button and voilá! Your song is transposed!

Azul is a music organizer that automatically extracts archives, converts file formats, splits audio by CUE and then intelligently identifies, tags, and renames. Just tell Azul what folder to scan and it will do the rest.

This is a toolbox for speech processing written in C. It realizes interface of Voicebox toolbox (http://www.ee.ic.ac.uk/hp/staff/dmb/voicebox/voicebox.html).

BeamformIt is an acoustic beamforming tool that accepts a variable amount of input channels and computes an output via a filter&sum beamforming technique. It can process all sorts of data acoustic files, leading to an homogeneous single output.

Extremely Lightweight Beat Detection Algorithm - BeatDetektor uses a very simple statistical model designed from scratch by myself to detect the BPM of music and provides real-time feedback useful for visualization and synchronization.

Program performs bird species recognition by their voices. In early stage of development but working well with some popular species and good samples quality.

It is an application for Bluetooth-enabled mobile phones that allows you to connect to other BluetunA users in range and share music recommendations. Mobile music, metadata sharing, Bluetooth applications, proximity-based interactions, social awareness

BpmDj: Free DJ tools contains an automatic & accurate BPM counter. Determines sound color, rythm & echo. The player provides measurejumps, persistent cue's and beatgraphs. The program requires multiple dsp's or computers. http://bpmdj.yellowcouch.org/

Braun is an application for visualising Open Sound Control (OSC) data on a scrolling graph.

HCI for audiovisual live performance exploiting physical computing. Transform your standard musical instrument - electric bass, guitar, violin, piano etc - in an augmented tool, an audiovideo controller without exploiting any specific ext. hardware.

"CAGE", the Computer Audio Garden in Eclipse, is to be an Eclipse-based, Java and XML workbench, for the computer music composer. It will use the Rich Client Platform to provide a basic backbone framework, enabling existing computer music tools to be p

CAMEL (Content-based Audio and Music Extraction Library) is an easy-to-use C++ framework developed for content-based audio and music analysis. The framework provides a set of tools for easy Segmentation, Feature Extraction, Domain Extraction, etc.

CQT-FW(Constant Q transform with Fixed length Window) is a time-frequency transform for multiple pitch recognition in audio signals(songs). The transform CQT(Constant Q Transform) provide analisys frequencies in a exponencial way, like music does, but it have problems with the time resolution. In CQT-FW we have the same frequency resolution as CQT, but with fixed length windows in time, what leads to a constant time resolution as well. And more, time and frequency resolution are not dependent like in CQT end DFT transforms. We also propose a post processing witch eliminate the high order harmonics, leaving only the fundamental frequencies. The transform got good results in a good range of frequencies, but still have problems in low frequencies.

Chord Reporter (hereafter abbreviated to CR) is a software program that displays the names of chords, as you play them (upon some MIDI controller or from a MIDI sequencer track). CR comes in two versions. There is an LV2 plugin that will run on any Linux program that loads such plugins. In that way, you can anaylze the chord progressions in your DAW's MIDI tracks. The second version is a Linux executable that runs on its own. You can directly attach your MIDI controller to this version to review the chords you're playing (as you play them). A suitable MIDI controller would be either a MIDI keyboard, a guitar equipped with a MIDI pickup such as the Fishman triple play, or even an electric guitar pickup plugged into a computer audio interface running pitch-to-MIDI software.
