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.

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

Create Unique Sounds with MixPad and WavePad

MixPad is typically used as a multitrack audio recorder and mixer instead of spending 10�s of thousands of dollars for a professional multitrack mixing desk. However, I like to use MixPad to create a variety of unique sounds I can use as sound effects or to play on my synthesizer. These sound effects can be used in commercials, movies, videos, music, audio programs, or by DJs on the radio. I still have a synthesizer in my basement midi studio that utilizes waveform oscillators to create sounds. One of them was advanced for the time and had 3 oscillators to create sound. With MixPad, I can create sounds with a virtually unlimited number of oscillators by loading snippets of sounds on the tracks and mixing them to create a new unique sound. MixPad has given me a range of possibilities I hadn�t had before.

To create your own sounds, once MixPad and WavePad are installed, all you need is a sound or waveform. You can get this from WavePad�s new sound library, NCH Tone Generator (another handy program from NCH Software), load an mp3 from your computer, rip tracks from a cd, or record a new sound with a microphone. I would begin in WavePad and play around with the sound. Listen to it forwards, backwards, apply live effects, etc. Once you have the fundamental sound, you can load it into MixPad to mix with other sounds. MixPad will allow you to stagger and mix the various snippets of sound you create. The result is a unique sound envelope that is yours and doesn't exist anywhere else in the world. Vanilla Ice could have learned a lot from this simple technique back in the early 90�s.
