Ääniominaisuuksien, which translates to "audio features" or "sound properties" in English, refers to the characteristics that describe and differentiate sounds. These properties allow us to perceive, identify, and interpret the auditory world around us. Key aspects of audio features include pitch, loudness, and timbre. Pitch is related to the perceived highness or lowness of a sound, determined by its fundamental frequency. Loudness, also known as intensity or amplitude, refers to the perceived strength or volume of a sound, typically measured in decibels. Timbre, often described as sound quality or tone color, allows us to distinguish between different instruments or voices producing the same note at the same loudness. This is influenced by the harmonic content and the way the sound changes over time.

Beyond these fundamental properties, other audio features can be analyzed. These might include the duration of a sound, its spatial location or direction, and its acoustic texture, which can describe the complexity or roughness of a sound. In fields like acoustics, audio signal processing, and psychoacoustics, the detailed analysis of these audio features is crucial for understanding sound, developing audio technologies, and even for artistic expression in music and sound design. For example, speech recognition systems rely heavily on analyzing specific audio features of human speech to identify words and phrases. Similarly, audio compression algorithms aim to efficiently represent sounds by focusing on the most perceptually relevant audio features, discarding less critical information to reduce file size without significant loss of perceived quality.
