Learning the language of sound
From: kzenon/123rf.com

Are you trying to describe how your headphones sound?

Does your favorite reviewer tend to wax poetic and use flowery prose when they describe what they hear, and you wonder what on earth they are talking about?

It’s always tough to put words to what your senses perceive. Have you ever tried to explain a smell or a color? Sound is no different. We often use descriptors from our other senses in an attempt to convey meaning.

As a result, common terminology has evolved in the audio industry to describe the ‘flavor’ of sound.

Headphonesty is here to help with our very own list of Audio Descriptors. Wherever possible, we’ve linked to related and opposite terms to help with understanding.

  • Decay: The sound immediately begins to decrease to the sustain level.
  • Sustain: The sound remains at this level until released.
  • Release: The sound decreases back to zero amplitude.
