GNU Radio ~ Software Radio Ecosystem

Posted by tom2tec on


GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in research, industry, academia, government, and hobbyist environments to support both wireless communications research and real-world radio systems.

GNOME Metronome ~ Keep The Tempo

Posted by tom2tec on

Keep the tempo

Metronome beats the rhythm for you, you simply need to tell it the required time signature and beats per minutes.

You can also tap to let the application guess the required beats per minute.

A boilerplate template to get started with GTK, Rust, Meson, Flatpak made for GNOME. It can be adapted for other desktop environments like elementary.

cdparanoia ~ Linux Digital Audio Extraction

Posted by tom2tec on

Cdparanoia is a Compact Disc Digital Audio (CDDA) Digital Audio Extraction (DAE) tool, commonly known on the net as a ‘ripper’. The application is built on top of the Paranoia library, which is doing the real work (the Paranoia source is included in the cdparanoia source distribution). Cdparanoia reads audio from the CDROM directly as data, with no analog step between, and writes the data to a file or pipe in WAV, AIFC or raw 16 bit linear PCM.

Cdparanoia is a bit different than most other CDDA extration tools. It contains few-to-no ‘extra’ features, concentrating only on the ripping process and knowing as much as possible about the hardware performing it. Cdparanoia will read correct, rock-solid audio data from inexpensive drives prone to misalignment, frame jitter and loss of streaming during atomic reads. Cdparanoia will also read and repair data from CDs that have been damaged in some way.

Cdparanoia is easy to use and administrate; It has no compile time configuration, happily autodetecting the CDROM, its type, its interface and other aspects of the ripping process at runtime. A single binary can serve the diverse hardware of the do-it-yourself computer laboratory from Hell.

aubio ~ Audio Labelling Library

Posted by tom2tec on

aubio is a tool designed for the extraction of annotations from audio signals. Its features include segmenting a sound file before each of its attacks, performing pitch detection, tapping the beat and producing midi streams from live audio.

Because these tasks are difficult, we thought it was important to gather them in a dedicated library. To increase the fun, we have made these algorithms work in a causal way, so as to be used in real time applications with as low delay as possible. Functions can be used offline in sound editors and software samplers, or online in audio effects and virtual instruments.

Features:

aubio currently provides the following features:

  • digital filters
  • phase vocoder
  • onset detection (several methods)
  • pitch tracking (several methods)
  • beat and tempo tracking
  • mel frequency cepstrum coefficients (MFCC)
  • transient / steady-state separation

foo_dsp_stereoconv ~ Natural Headphone Crossfeed

Posted by tom2tec on

​Natural crossfeed Foobar2000 component designed to give a realistic crossfeed / speaker simulation effect on headphones or earphones while producing a wide soundstage and zero sound coloration.

Simulates speakers spaced 30+30 degrees apart (classic stereo setup with better front projection of imaging) or 50+50 degrees apart (widened stereo setup with more similarity to classic headphone soundstage width)

Update 2016-07-26: I’ve put the “secret” update in public as v2.1, containing a new set of impulses. They also come in 30+30 degree and 50+50 degree versions but are derived from actual measurements around my head.
