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

SpatGRIS ~ Multichannel Composition

Posted by tom2tec on

The SpatGRIS is a plugin (Mac AU/VST and VST Windows format) designed to compose multichannel space. It allows the user to spatialize the sound in 2D (up to 16 speakers) or in 3D (up to 128 speakers) under a dome of speakers (with the ServerGRIS, available also on SourceForge). It includes two audio modes, — Free Volume and PanSpan — and one OSC mode. SpatGRIS is a fusion of two former plugins by the GRIS: OctoGRIS and ZirkOSC with a lot of new features. Automated Trajectories are included. It is possible to control it from external controllers such as Joystick, iPad or Leap Motion.

Features:

  • Three modes: Free Volume, Pan Span, OSC Spatialization
  • Automated Trajectories
  • Up to 16 outputs in audio mode
  • OSC Mode to control the ServerGRIS
  • External controllers: Joystick, iPad. Leap Motion

DarkIce ~ Live Audio Streamer

Posted by tom2tec on

DarkIce records audio from an audio interface (e.g. sound card), encodes it and sends it to a streaming server.

DarkIce can record from:

  • OSS audio devices
  • ALSA audio devices
  • Solaris audio interface
  • Jack sources
  • uLaw audio input through a serial interface
  • CoreAudio (branch darkice-macosx)

DarkIce can encode in the following formats:

  • MP3 – using the lame library
  • MP2 – using the twolame library
  • Ogg Vorbis
  • AAC LC – using the faac library
  • AAC HEv2 – using libaacplus library
  • Opus – using Xiph’s libopus library
  • Vorbis – using Xiph’s libvorbis library

DarkIce can send the encoded stream to the following streaming servers:
