    • My Favorites (What is 'My Favorites'?)
      'My Favorites' is a special kind of lens which you can use to bookmark modules and collections directly in Connexions. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need a Connexions account to use 'My Favorites'.
    • A lens (What is a lens?)

      Definition of a lens

      Lenses

      A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

      What is in a lens?

      Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

      Who can create a lens?

      Any individual Connexions member, a community, or a respected organization.

MATLAB EQ: Results

Module by: Niklos Maureira

Summary: End result of our Visual Equalizer.

Results

Figure 1
Figure 1 (graphics1.jpg)

The above figure is a demonstration of the end result of our Visual Equalizer.

As shown, we were able to implement a real-time spectrum analysis of the signal in dual-channel (stereo) mode, with the preprocessed signal on the left and the post-processed signal on the right. The graphs on the bottom represent the 10 binned frequency blocks in a logarithmic queue up to 22.05 KHz.

Each frequency block can be adjusted to modify the gain levels. The Distortion, Flange, and Reverb options implement each command in the left channel, right channel, or dual-channel modes. The Volume control is the Unity Gain, increasing the amplitude over all the frequency blocks. The Start and Stop buttons begin or end the visual spectrum processing.

As a bonus, we threw in audio presets such as Rock, Treble Booster, Bass Booster, etc.
