It is a interesting research!

Qualitative Research Analysis Tool - Media Analyzer

Qualitative Media Analyzer is a computer program for qualitative analysis of interviews or observations, where the interviews/observations are stored as digitized audio and video recordings.
  • User interface is simple and accessible, and despite very advanced technical functions, Qualitative Media Analyzer is easy to use.
  • Interviews (audio-, video recordings) are collected in a folder, which can contain maximum 300 interviews, where each interview can have the duration of 18 hours. Each interview can have one or more persons attached, hereby it is possible to follow the work of the persons and one has the possibility to compare scores made by two or more persons.
Audio recordings: WAV, Windows Media Audio, AIFF, MP3

Video recordings: MPEG-1, MPEG-2*, Windows Media Video, AVI, Apple QuickTime 1.0-5.0

The media can be on hard disk, CD-data disc, networks and a combination of all. The media can be combined in a folder, where it is possible to mix audio and video recordings in the same folder.

Features

  • Sound: Wave, Windows Media Audio, AIFF, MP3
  • Video: MPEG-1, MPEG-2*, Windows Media Video, AVI, Apple QuickTime 1.0-2.0
  • 300 interviews sounds, videos, tracks in one folder (in theory 5400 hours per folder)
  • Mix of source: I.e. insert sound- and video recordings in one folder
  • Grouping of interviews
  • Nested codes for scores (max. 65.568 codes)
  • Unlimited number of scores - only limited by memory
  • Unlimited number of notes - only limited by memory
  • Annotation to scores, where the annotation can be text, audio or video
  • Links between scores, other media documents
  • Advanced analysis with Booleans, user defined conditions

* MPEG-2 requires special MPEG-2 drivers

Price: 2800 D.KR excluding local tax/VAT (350 US$). Delivered on CD-ROM disc
