Audio Analyzers

9 Best Free and Open Source Audio Analyzers

There is a huge range of open source free audio software available for Linux which is both mature and feature-laden. Linux has all the tools needed to be a serious contender in music production without a user having to venture into the commercial software world. Linux is a superior platform for professional audio production: rock solid, efficient, and you don’t get fleeced for software licenses. Software that creates music can often be expensive.

Linux also sports a wide range of useful audio tools. This article examines audio analyzers. This type of software lets you visualize audio spectrum for real-time signals. Some of the programs also lets you analyze amplitude and phase spectrum as well. Also, you can visualize audio spectrum in FFT spectrum, 2D spectrogram, Octave spectrum, etc. modes.

This type of software is useful for audio/multimedia researchers, developers, composers, and performers. They help you analyze an audio signal to understand the characteristics of this signal (fundamental, harmonics, feedback, etc.), to describe the source/room/receiver behaviour (reverberation, gain peaks, etc.), or to make adjustments in the preprocessing (room equalization).

We also include software that lets you identify songs.

Here’s our verdict summarized in one of our legendary ratings chart.
