WavePad FFT Spectrum Audio Analysis Software

WavePad sound editor is more than just an easy audio editing program. Once you scratch the surface there are powerful audio engineering tools available for the more advance user. These tools include the Fast Fourier Transform (FFT) and the Time-Based Fast Fourier Transform (TFFT) which are both very useful tools to perform sound analysis on the spectral content of audio. These audio spectrum analyzer tools have applications in a number of areas, including linguistics, mathematics and sound engineering including reducing noise and vibration testing and analysis.

Audio FFT Graph

\ The FFT analyzer graph is designed to illustrate characteristics of audio at only one point in time. It takes a small sample of audio and plots the sound frequency in Hz against the audio intensity in decibels. If the audio is in stereo two lines will be plotted on the graph, otherwise just the one plot will be displayed.

Audio TFFT Graph

The TFFT graph maps the audio intensity of the frequency spectrum across time for the duration of the audio clip, representing the intensity through color. On this graph the x-axis is time and the y-axis is the frequency with the decibel intensity being mapped to the color intensity scale, with black representing -128 dB and white representing 0 dB.

Both the discrete and temporal fast fourier transform frequency analysis graphs can be created/opened from the Tools tab and both graphs will update in real time as you move to different positions in the audio file, or even as you play the audio so you can better see what is happening in the audio. So, download WavePad audio analyzer software to take a closer look at audio and learn how to analyze voice patterns and more.

Boosting the Bass in Audio Files

Want to boost up the bass in your music? The Equalizer in WavePad music editing software is your answer. Open your song in WavePad and select Equalize on the Effects tab. Equalizing allows you to adjust the level of frequencies in your audio amplifying ranges of sound frequencies. So you can change the volume of just the higher or lower (bass) frequencies in a song, as opposed to simply amplifying a song which will affect all of the frequencies.

Unlike a graphic equalizer you might see in a studio, with a multitude of knobs and dials for certain frequencies, the WavePad equalizer displays a graph of the frequencies going from the low frequencies at the left to the high frequencies on the right giving you very finite control of the frequency ranges you want to control. Move a point up on the graph to make the frequency stronger and lower a point to make it weaker.

To familiarize yourself with the equalizer take advantage of the presets to get started, but don't be afraid to play around with them and to adjust their settings to see how they affect your songs. To boost the bass start with the Low Pass filter presets. If you hit play you will hear the higher frequencies drop down, giving a boosted effect to the bass. Chances are the result won't be exactly what you wanted on the first shot, but this will provide a good starting place to make further adjustments. Changes aren't applied until you actually click Apply, so you can continue to tweak the graph as needed without fear.

Other preset filters include a High Pass Filter which is the opposite of the Low Pass Filter lowering the bass instead of the higher frequencies, a Band Pass Filter to maintain the frequencies in a specified range and lower the regions above and below that section, and several more that you can experiment with on your own, or go to the help for more details on the settings of each of these presets.

WavePad: New Look, New Tools, New Features

Change doesn't have to be scary; in this case it�s really exciting: WavePad has a new look. Now, instead of tiny icons and long and packed menus, WavePad uses a ribbon toolbar to organize functionality by category. It really is easier to use than ever before.

WavePad continually receives praise for its user-friendliness. The interface isn�t intimidating to the beginner, yet doesn�t bury the advanced features more experienced audiophiles use on a regular basis. Its feature set includes recording, editing, and effects such as amplify, normalize, reverb, echo, and reverse and is extended by DirectX effects and VST plugin support, and an included royalty-free sound effect library. The new ribbon toolbar organizes all these aspects of the program, improving an already easy-to-use workspace.

Here is the Effects toolbar. Look how the features pop out at you:



There�s more to this latest version of WavePad, including the following features and tools:

• Wah-wah effect, for emulating wah-wah guitar pedals
  
• Vibrato effect, for modulating the depth and frequency of an audio sample�s pitch
  
• Tremolo effect, for modulating the depth and frequency of an audio sample�s amplitude
  
• Doppler effect, for simulating the sound of a passing vehicle from a higher to a lower pitch
  
• Pitch speed profile tool, for changing the speed or pitch of select portions of an audio sample
  

WavePad version 5.0 is a major release, and we want you to experience it yourself. Download your copy of WavePad now.

Give Your Music a Boost: The WavePad Equalizer

I have noticed a lot of questions on our YouTube channel about enhancing the bass in a song using WavePad audio editor. How is it done? Since the graphical interface of WavePad's equalizer was recently updated, now is the perfect time to review how to use it.

The first thing you want to do is load your music into WavePad. Do this by clicking the Open File icon on the toolbar, browse to your music file, and click Open.

Next, click the Effects menu and select Equalizer. This will open the Equalizer dialog, which might not be what you expect if you were looking for knobs and dials. This equalizer still weakens and strengthens frequencies like knobs on a mixing board, but represents the frequencies in graph form. The graph works logically enough; the low frequencies are represented on the left of the graph, the high frequencies on the right. If there is a point on the graph line that is higher, that frequency will be stronger. If the graph point is lower, the frequency will be weaker.

The easiest way familiarize yourself with this equalizer is to make use of the presets. Don't be afraid to play around with them and to adjust their settings to see how they affect your music--you don't have to commit to any changes until you click Apply.

Let's boost the bass as an example. Click the Play button and then select the Low Pass filter from the list of presets. You'll hear the higher frequencies drop down, giving a boosted effect to the bass. The result probably isn't exactly the sound you imagined, so you can make adjustments based on this starting place to even out the sound how you want. You can do this using the Low Pass Options dialog that opened when you selected this preset, but you'll have more control if you close the dialog and move around the graph points yourself. You can also add graph points by clicking on the graph's line.

For more information about how to use the different equalizer presets, view the Effects topic in the help manual. For more information about frequencies, view the General Audio Concepts topic, also in the help manual. The help manual is accessed by pressing F1 from the program.

To try WavePad and boost your bass, download the program from our website. You'll also want to see the other audio software we have for maximizing your audio production.

ToneGen your way to the Center of the Universe

What if I told you that Tone Generator Software could cure cancer or could attribute itself to miracles? Not a bold enough statement? What if I told you that it could elevate human kind to the highest levels of human consciousness and understanding and perhaps save the planet?

The 528 Hz frequency, also known as the Solfeggio or love frequency, is associated with everything from DNA repair to miracles. Found especially within new age belief circles, proponents of the theory claim that the entire universe is constructed through a musical, mathematical matrix composed of nine core creative frequencies. According to the belief, the Solfeggio frequency is the key component of this matrix and the frequency can be found in everything from sunlight to oxygen and all manners of human interaction from laughing to yawning. It is also sometimes called the love frequency, a frequency that can help human beings achieve a higher level of consciousness, purpose and ultimately, world peace.

It might sound crazy and if you�ve never heard of the 528 Hz anomaly before, you�re probably not alone...but that doesn�t mean you�re not subliminally aware. Many believers contend that people are aware of this frequency at a purely subconscious level, as it resonates outward from people as joy. By shutting out negative frequencies (such as A440 Hz) and embracing the positive, one can achieve a deeper understanding of self and live a happier, healthier and more fulfilling life, existing as one with the center of the universe.

Ready to achieve a higher level of purpose? If so, ToneGen can help you get started. It�s free to try and easy to use, so set the frequency to 528 Hz, light a candle and meditate your way to the center of the universe.

If you'd like to learn more about the Solfeggio frequency, here's a good place to start. http://www.burlingtonnews.net/blog/?p=16
