Audio Feature Analysis

The Feature Analysis enables you to understand the core properties of your audio files. It processes and examines various characteristics such as duration, samples, amplitude, among others, providing a detailed analysis of the sound structure and quality.

To use this feature, select 'Choose File' and pick the audio file you wish to analyze. Then, press 'Upload' to initiate the process. The system will process your audio and return a detailled feature analysis.

Behind the Scenes

In the context of audio processing, audio features refer to specific aspects of an audio file that provide insights into its nature and content. These features often include technical elements such as duration, sample rate, channels, and amplitude.

Feature analysis is the process of extracting and studying these elements to understand the characteristics of the audio file. This process is fundamental to various applications in digital audio, such as audio editing, sound design, and audio data compression.

In digital audio, a sample is a discrete value that represents the amplitude of the sound wave at a specific point in time. The sample rate, measured in Hertz (Hz), is the number of these samples taken per second.

For example, a sample rate of 44.1 kHz (the standard for audio CDs) means 44,100 samples are taken each second. A higher sample rate provides a more accurate representation of the sound wave, but it also results in larger file sizes.

In audio, a channel refers to an individual stream of audio. A mono audio file has one channel, a stereo audio file has two channels (typically one for the left speaker and one for the right speaker), and a surround sound system may have five or more channels.

Each channel in an audio file can be thought of as a separate waveform carrying unique audio information.

Amplitude in an audio signal represents the magnitude or strength of the sound wave at any given point in time. It is directly related to the loudness of the sound. In the context of audio analysis, the maximum and minimum amplitude values are of particular interest.

The maximum amplitude refers to the highest point that the sound wave reaches, which corresponds to the loudest part of the audio. On the other hand, the minimum amplitude refers to the lowest point that the sound wave reaches, representing the quietest part.
