OM-SuperVP

The OM-SuperVP library allows to program processes and set parameters in OM for the SuperVP sound processing kernel.

The OM-SuperVP tools are organized in three main categories : analysis, processing, and synthesis.

OM-SuperVP provides :

  • a user-friendly interface to the sound processing kernel in your favorite computer-aided composition environment ;

  • formatting sound processing or analysis parameters for SuperVP using OM symbolic/musical objects and visual programming tools ;

  • designing complex processes including itérative/sequencial calls to the sound processing kernel ;

  • connecting SuperVP processes to compositional processes and models developed in OM ;

  • ...

  • OM-SuperVP design and development : Jean Bresson & Jean Lochard
  • SuperVP is developed and distributed by IRCAM - Analysis/Synthesis team (see the SuperVP page on ForumNet)

Configuration

OpenMusic Setup

Once the OM-SuperVP library is loaded in OM, a new item will appear in the Externals tab of the OM Preferences window :

In principle SuperVP is already present in your library, but you can optionally specify the path to another location where it might be installed.

About SuperVP path setup

  • OM will display the kernel path in red if it is not found or not set correctly.

  • With the AudioSculpt installation, the sound processing kernels can be found inthe AudioSculpt x.x.x/Kernels/ folder.

File Formats

Parameters files

Most SuperVP processes use input files to read the parameters for sound treatments.

The parameters files are generally formatted as text, can can therefore be written and read using standard text editors (or TextFile objects in OM). They also require accurate formating knowledge in order to work correctly, this formatting being variable depending on the different sound treatments and processing. OM-SuperVP will allow you to ignore these formatting issues and convert standard OM objects (lists, BPFs, etc. into adapted pârameters files for SuperVP.

The default location for reading/writing the SuperVP parameters files can be set in the SuperVP preference (see the options button in the picture above). The following option window will allow you to change this path if desired.

Analysis Files

All SuperVP sound analyses results are stored ans returned as SDIF files : the analysis functions return a file pathname to connect to the SDIFFile object.

SDIF file contents can be inspected and converted to data lists or OM objects using the SDIF package tools.

Using/Understanding SDIF Files

Library Design and Sound Processing Options

OM-SuperVP boxes have a number fixed of inputs + somme additional keyword inputs.

Generally speaking, the options proposed in the OM boxes strictly match the corresponding options in AudioSculpt. Type d to get an overview and description of the different options of the OM-SuperVP boxes.

Consult the AudioSculpt User Manual in order to understand and set the values of these parameters.

See how to use keyword inputs in the OM User Manual.
