Based on Appendix B from the EBU Tech 3286-1997 document, this guide provides a structured approach to analyzing the sonic characteristics of a recording.

I. Overall Impressions and Technical Quality⌗

First Impressions: What is your immediate reaction to the recording?

  • This should be a subjectively weighted average of the other parameters, considering the integrity of the total sound and the interaction between parameters
    • Does it feel balanced, immersive, or engaging?
    • What is the most striking sonic characteristic?

Freedom from Noise and Distortions:

  • Are there any unwanted noises (electrical hum, background noise, digital artifacts)?
  • Are there distortions or unexpected interruptions in the sound?

Bandwidth and Recording Quality:

  • Does the recording sound full and rich, or does it feel limited in frequency range?
  • How would you rate the technical quality of the recording overall?

II. Spatial Attributes⌗

Spatial Impression:

  • How does the recording create a sense of space?
  • Does it sound dry, reverberant, or somewhere in between?
  • How large does the recording environment feel?

Stereo Image and Sound Positioning:

  • Is the soundstage wide or narrow?
  • Can you clearly locate different sound sources, or do they blend together?
  • Are there any spatial effects like panning, delay, or reverb that enhance the sense of depth?

Time-Based Effects:

  • Do you notice echoes, delays, or modulations?
  • How do these contribute to the perceived space and movement of the sound?

III. Timbre and Spectral Balance⌗

Spectral Balance:

  • Are any frequencies particularly dominant or lacking?
  • Does the track sound bright, dark, warm, or harsh?

Timbre of Sound Sources:

  • How would you describe the tonal quality of individual instruments or voices?
  • Do they sound natural or processed?
  • Does the timbre remain consistent, or does it change over time?

Comparison to Genre Expectations:

  • How does the timbre of this recording compare to similar recordings in the same genre?
  • Are there any unique sonic characteristics that stand out?

IV. Sound Balance and Dynamics⌗

Instrumental and Vocal Balance:

  • Are all elements mixed appropriately, or does anything stand out too much or too little?
  • Are the relative levels of instruments and voices appropriate for the style?

Dynamic Range:

  • Is there a noticeable contrast between loud and soft moments?
  • How does the recording’s dynamic variation contribute to its emotional impact?

Loudness and Perceived Energy:

  • Does the loudness level feel appropriate for the style of the music?
  • How does the track’s loudness affect its energy and intensity?

V. Transparency and Clarity⌗

Layering and Separation of Sounds:

  • Is it easy to hear and distinguish different elements in the mix?
  • Are any elements masked or buried under others?

Clarity of Individual Sounds:

  • Do the instruments or vocals sound crisp and well-defined?
  • Are there any elements that are too sharp or too muddy?

VI. Additional Artistic and Contextual Considerations⌗

Aesthetic and Artistic Impact:

  • Does the recording sound natural, artificial, or heavily processed?
  • How does the sound contribute to the artistic intent of the piece?

Performance Energy and Expression:

  • How would you describe the performers’ intensity and emotional expression?
  • Does the sonic presentation enhance or diminish the musical performance?

Artifacts and Processing:

  • Are there any audible effects of compression, equalization, or digital manipulation?
  • Do any artifacts distract from the listening experience?

VII. Playback System and Listening Environment⌗

Playback Setup:

  • What system are you using to listen to the recording (headphones, speakers, laptop)?
  • How might your playback device be altering your perception of the sound?

Listening Environment:

  • Are there background noises affecting your ability to analyze the recording?
  • How might the acoustics of your space influence what you hear?

Final Discussion Questions⌗

  • Based on your analysis, what aspects of this recording are particularly strong?
  • Are there areas that could be improved? If so, how?
  • How does the production style influence the overall feel of the track?
