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

FreeG ~ Fader Plug-in

Posted by tom2tec on

The Sonalksis FreeG is everything you need in a master fader. A simple, but absolutely indispensable plug-in, FreeG extends the functionality of a typical audio host by providing a large-format style fader, along with ultra accurate metering. FreeG helps to maximise workflow with extended, customizable metering, and multiple control features and settings.

When working with digital audio, a lack of fine metering and extended signal flow control in the host is a common issue. FreeG helps to improve workflow in the host by providing these features in the insert chain. By delivering enhanced control of amplitude, phase and pan (stereo version) in the insert chain as well as fine metering, with user configurable industry standard ballistic options, the freeG is the perfect master control.

Features:

  • Long-throw fader
  • Ultra accurate metering
  • Multiple metering ballistic types
  • Peak and RMS readouts
  • Pre/Post metering options
  • Selectable Pan-Law
  • ‘Fine’ mode for sensitive calibration of the master fader
  • Mono-compatible for use in tracking situations
  • VST and Audio Unit (32 and 64 bit)

Spleeter ~ Source Separation Library

Posted by tom2tec on

Spleeter is the Deezer source separation library with pretrained models written in Python and uses Tensorflow. It makes it easy to train source separation model (assuming you have a dataset of isolated sources), and provides already trained state of the art model for performing various flavour of separation:

  • Vocals (singing voice) / accompaniment separation (2 stems)
  • Vocals / drums / bass / other separation (4 stems)
  • Vocals / drums / bass / piano / other separation (5 stems)

2 stems and 4 stems models have state of the art performances on the musdb dataset. Spleeter is also very fast as it can perform separation of audio files to 4 stems 100x faster than real-time when run on a GPU.

We designed Spleeter so you can use it straight from command line as well as directly in your own development pipeline as a Python library. It can be installed with Conda, with pip or be used with Docker.
