Definitions, Formats, Types

Audio files

DSProlog can handle the following audio-file formats:

  1. Uncompressed Microsoft PCM (.wav); one channel (mono); bit depth: 8, 16, 20, 24 or 32 bit; any sample rate.
  2. Uncompressed PCM without header (.dat); one channel (mono); bit depth: 8, 16, 20, 24 or 32 bit; any sample rate. Bit depth, sample rate and offset for .dat-files have to specified in the 'Project Settings' window.

Visualizations

Visualizations are graphical representations (spectrograms, phase spectrograms, oscillograms, sound pressure level diagrams etc.) of acoustic phenomena. They can be created and modeled in the VIS-Editor. Visualizations are stored as .vis-files in the project-folder "Visualizations".

Classifiers
  1. First-Level-Classifiers (FLC) are detectors for elementary acoustic patterns. They can be created and modeled in the FLC-Editor. FLC are stored as .flc-files in the project-folder "FL-Classifiers".
  2. Second-Level-Classifiers (SLC) are detectors for complex acoustic patterns. They can be created and modeled in the SLC-Editor. SLC are stored as .slc-files in the project-folder "SL-Classifiers".
Annotations
  1. First-Level-Annotations are FLC-decisions referring to elementary acoustic events. FL-Annotations are stored in CSV-data tables (.csv) in the project-folder "Annotations/FL".
  2. Second-Level-Annotations are SLC-decisions referring to complex acoustic events. SL-Annotations are stored in CSV-data tables (.csv) in the project-folder "Annotations/SL".

The annotations database-interface provides tools to browse, search and filter Annotations.

Profiles

Properties of visualizations and classifiers can be stored as profile-files in the project-folder "Settings". Several predefined profiles are provided by DSProlog. Three types of user-defined profiles can be created: Visualization-profiles (.visp-files), FLC-profiles (.flcp-files) and SLC-profiles (.slcp-files).

Bitmaps

Visualizations of audio data, graphical representations of classifiers and annotations can be exported as standard 24-bit bitmaps. The resolution of bitmaps can be changed in the "Options" window. Bitmaps are stored by default in the project's export directory.
