Rakarrack ~ Guitar Effects For Linux

Posted by tom2tec on

Rakarrack is a richly featured multi-effects processor emulating a guitar effects pedalboard. Effects include compressor, expander, noise gate, graphic equalizer, parametric equalizer, exciter, shuffle, convolotron, valve, flanger, dual flange, chorus, musical delay, arpie, echo with reverse playback, musical delay, reverb, digital phaser, analogic phaser, synthfilter, varyband, ring, wah-wah, alien-wah, mutromojo, harmonizer, looper and four flexible distortion modules including sub-octave modulation and dirty octave up. Most of the effects engine is built from modules found in the excellent software synthesizer ZynAddSubFX. Presets and user interface are optimized for guitar, but Rakarrack processes signals in stereo while it does not apply internal band-limiting filtering, and thus is well suited to all musical instruments and vocals. Rakarrack is designed for Linux distributions with Jack Audio Connection Kit.

EasyQ ~ Easy To Use Equalizer

Posted by tom2tec on

EasyQ is an easy-to-use equalizer with an arbitrary number of filter stages in series connection. Each of the filter stages can operate in one of the following modes: peak/cut (aka bell or parametric EQ), high- or low-shelving, notch and low- or highpass (both with either 6 or 12 dB/oct slope). EasyQ is also easy on the CPU and just does what an EQ is supposed to do without performing any additional voodoo. As such, it is well suited to serve as a go-to EQ for the routine equalizing tasks.

Key Features:

  • unlimited number of filter stages (“bands”)
  • each stage can be one of the following characteristics: bell, low-/high-shelf, low-/highpass (6 or 12 dB/oct), notch
  • clean equalization – no additional colorations
  • low CPU usage
  • +-48 dB gain range
  • stereo modes: linked, left/right, mid/side and mono
  • minimum phase response

mktoc ~ Generate cdrdao TOC Files

Posted by tom2tec on

Mktoc simplifies the steps needed to create audio CD TOC files for the cdrdao CD burning program. For users familiar with EAC or CdrWin, TOC files are synonymous with CUE sheets. The primary goal of mktoc is to create TOC files using a previously generated CUE sheet.

Features:

  • Create a TOC file from a list of WAV files.
  • Convert an ExactAudioCopy (EAC) CUE file to the TOC format that is usable by cdrdao.
  • Multi-session aware CUE parsing, necessary for making CDDB and AccurateRip matchable discs.
  • Non-compliant CUE sheet support.
  • Support for various pregap methods.
  • Can create offset corrected WAV files for true ‘bit-for-bit’ accurate copies.
  • Fuzzy file name logic can correct common file name spelling variations.
  • Workaround known TOC file parsing bugs in cdrdao.

Cdrdao ~ Disk-At-Once Recording

Posted by tom2tec on

Cdrdao records audio or data CD-Rs in disk-at-once (DAO) mode based on a textual description of the CD contents.

Advantages of Disk-At-Once (DAO) Recording:

Recording in disk-at-once mode writes the complete disc, i.e. lead-in, one or more tracks and lead-out, in a single step. The commonly used track-at-once (TAO) mode writes each track independently which requires link blocks between two tracks. Older CD-recorder models forced a two second pause (pre-gap) between two tracks whereas newer models allow adjusting of the pause length in TAO mode reducing the number of link blocks to a minimal amount. However, with TAO it is generally not possible to define the data that is written in pre-gaps. But exactly this feature makes audio CD recording interesting, e.g. by creating hidden bonus tracks or track intros in pre-gaps like it is common habit on commercial CDs. Finally, DAO recording is the only way to write data to the unused R-W sub-channels for e.g.  CD-G or CD-TEXT.

Features:

  • Full control over length and contents of pre-gaps (pause areas between tracks). Pre-gaps may be completely omitted, e.g. for dividing live recordings into tracks.
  • Control over sub-channel data like:
    • catalog number
    • copy, pre-emphasis, 2-/4-channel flags
    • ISRC code
    • index marks
  • Support for exact audio, data and mixed mode CD copying.
  • Support for R-W sub-channel writing.
  • Tracks may be composed of different audio files supporting non destructive cut.
  • Accepts WAVE and raw audio files.
  • CD-TEXT reading and writing with drives that support it.
  • CDDB access to automatically create CD-TEXT data.
  • Support for on-the-fly copying.

Yoshimi ~ Linux Software Synthesizer

Posted by tom2tec on

Yoshimi is a software audio synthesizer, originally forked from ZynAddSubFX. Follow the links in the header for help with downloading and running it. You can also check out the manuals for detailed help, and listen to examples of music created with Yoshimi. Once you have it all set up, here are just some of the features you will find:

  • Three separate engines, each with distinctive characteristics, can be used together or individually
  • Sixteen engine kits for the ultimate in multi-layering of engines, or for synthesized drum kits
  • Vector Control, manage up to four independent sounds on any channel with faders or an X/Y midi joystick
  • Solo step through up to 16 sounds seamlessly while playing in real time (including vector sounds)
  • Microtonal Tuning, Scala-compatible scales and keymaps
  • Extensive Midi-Learn, capture almost all internal controls and many switches with ordinary 7-bit values, or NRPNs, or even 7-bit NRPNs, then edit the responses
  • Command Line Access, headless operation and high accessibility, for those with sight- or motor control issues
  • Rich variations of tone and timbre, Yoshimi provides the means to ensure no two notes are ever identical – just like in the real world
