Linear Spectrum and Oscilloscope Visualizer

This is an audio visualization tool that can export videos of a linear spectrum, tuned short waveform, long waveform or stereo oscilloscope of a song.  It supports multiple audio and video formats.

It draws a white linear spectrum, waveform or oscilloscope over a black background for further processing with a video editor of your preference.

Here's what you can do with it:

Why?

This small project started due to the omnipresence of logarithmic spectrum visualizers and the apparent absence of linear spectrum visualizers (apart from the one in After Effects). Once I made this, I decided to also include the other three types of visualizers.

Features included are:

• Height and width resolution
• Frame rate
• Thickness of the plot
• Video compression

Additionally, for Linear Spectrum:

• Select between the right, left or both channels
• Time smoothing
• Frequency limits
• Mid and high frequencies boost
• Amplitude range expander
• Scatter, line or filled plot
  

For Short Waveform:

• Select between the right, left or both channels
• Tuning
• Window size
• Scatter, line or filled plot
  

For Long Waveform:

• Select between the right, left or both channels
• Window size
• Scatter, line or filled plot
  

For stereo Oscilloscope:

• Up-sampling

Usage:

• Place your audio file in the same folder the executable is.
• The video will be exported to the same folder. [WILL OVERWRITE]
• FFmpeg is required.
• The oscilloscope generator only works with stereo files as it wouldn't make any sense to visualize a mono file with a stereo oscilloscope.

Tips for Windows:

• It seems that you need to install FFmpeg manually and add it to PATH.
• The default Windows video player is not gonna play the exported videos correctly. Try VLC instead. (You'll be able to use the exported videos in any video editing software just fine, though)

Feel free to comment about any bug that may appear while you use it.
