AudioRozza™

Overview

AudioRozza™ is a multipurpose audio recorder.

Originally designed for radio broadcast monitoring, AudioRozza™ has evolved into a flexible solution for a variety of audio recording applications, providing three different recording modes, real-time audio compression, customisable embedded metadata and intuitive file storage layout.

*Rozza - British English slang for the police.

Features

  • Recording Modes
    AudioRozza™ provides three recording modes, which can be used in any combination:
    • Continuous Recording
      AudioRozza™ records an audio source is continuously in to manageable 1 hour long audio files. A seemless transition between recording to one file and the next means that no audio information is lost.

    • External Trigger Recording
      Using an external trigger (such as a switch or relay), AudioRozza™ is triggered to record an audio source whenever the external trigger is activated. The External Trigger Recording mode makes it ideal for situations where you only want to record when a physical event takes occurs (e.g.: a fader, switch or relay is opened or closed).
      Radio stations have wired up their studio's mixing desk to trigger the External Trigger Recording only when the studio microphone is activated. This provides their DJs and announcers with a dialogue-only recording of their shows for them to analyse.

    • Audio Level Recording
      With the Audio Level Recording mode, AudioRozza™ continuously monitors an audio source for a sound level that goes above (or below) a preset sound level threshold before audio recording is initiated. The recording will continue until the sound level goes below (or above) the preset sound level for a specified period of time. This mode is ideal for recording conversations or sound events which occur unpredictably.
  • Gain Control
    If the audio signal is not at the required recording level, AudioRozza™ has the ability to amplify or attenuate the incoming audio signal before it is written to the audio file.
  • Level Meters
    The AudioRozza™'s recording level meters provide a graphic representation of the incoming audio signal level as well as the post Gain Control level, ensuring that the audio source is being recorded at the correct level.
  • Audio Compression
    AudioRozza™ by default stores the recorded audio in the uncompressed Waveform Audio file format (also known as WAV or WAVE), however AudioRozza™ also provides the ability to use third-party audio codecs to compress the recorded audio on-the-fly into a compressed audio format, such as the popular MP3 and Vorbis formats, and at the same time providing full control over the codec's compression settings.
  • Embedded Metadata
    AudioRozza™ provides the facility to add customised metadata (data related to the audio recording) and automatically embed it into the recorded audio files.
    The metadata is stored within the audio file using popular metadata containers such as ID3 (ID3v1 and ID3v2) commonly used within MP3 audio files, as well as the INFO chunck of the RIFF (Resource Interchange File Format) used within WAV files.
    Most Digital Audio Workstations (DAWs), such as Adobe® Audition®, non-linear editing and media player software are capable of reading this metadata, suppling the sound editor with more detailed information about the recording.
    AudioRozza™ also provides the option of inserting dynamic data into the metadata fields, including:
    • The start date and time of the recording (or a subset thereof).
    • The end date and time of the recording (or a subset thereof).
    • The audio codec used to convert the captured audio into a compress format.
    • The name of the audio capture card used.
    • The version number of the AudioRozza™ application used to perform the audio capture.
  • Configurable Directory Structure and File Naming
    AudioRozza™ provides a veriety of directory storage options as well customisable file naming conventions to allowing recorded audio files to be quickly and efficiently located or archived.
  • Windows® Service
    AudioRozza™ can also be run as a Windows® Service. This means that AudioRozza™ can start running as a background process as soon as Windows® is loaded, allowing AudioRozza™ to record audio without first requiring a user to login to Windows®.
