How to Reduce a 60 Cycle Hum

Removing a hum below 60 cycles-per-second will help you improve the quality of your music and reduce unwanted noise. Audio filters make it possible to completely remove frequencies under a specified frequency range. You must use an audio editing program to accomplish the task of removing the hum. By applying a carefully constructed audio filter, you can isolate and remove the hum with ease. To effectively reduce the hum, you must use a high-pass filter that removes frequencies below the specified frequency which are measured in hertz, or cycles-per-second.

Step 1

Open your audio editing program and drag your audio file into the main window to import your audio for editing.

Step 2

Find the "Effects" menu at the top of the screen. All audio editing programs have an effects menu. Sometimes it is labeled as "Audio Effects."

Step 3

Select the "High Pass Filter" from the list of options in the "Effects" drop-down menu.

Step 4

Type the number 65 into the "cutoff frequency" or "hertz" box. Press "OK" and the hum will be reduced and in some cases completely removed.

Tips

Hertz is abbreviated as "Hz." If you have trouble finding hertz in your high pass filter, look for the abbreviation.

If the hum remains, try changing the cutoff frequency to 70.

Why Claude Debussy Never Cared About Music Theory

Claude Debussy was born on August 22, 1862. So, I felt writing a blog post to celebrate would be appropriate. Debussy was a revolutionary composer who challenged the conventions of Western music. He was influenced by the impressionist painters, the exotic sounds of gamelan music, and the symbolist poets. He created a musical language that was expressive, colorful, and atmospheric. One of the most remarkable aspects of Debussy's music is his use of harmony. He did not follow the rules of tonality and functional harmony that dominated the music of his time. Instead, he used modes, scales, chords, and parallel movements that created a sense of ambiguity and fluidity. He also experimented with timbre, texture, rhythm, and form to create musical images that evoked moods and emotions. Debussy's music can inspire us to think outside the box and explore new possibilities in our own compositions. We can learn from his innovative techniques and his artistic vision. We can also apprecia...

List of Musical Techniques and Their Meanings

Musical techniques are the building blocks of any basic music training. These techniques allow performers to improve their coordination and develop accuracy through repetitive daily exercises. Musical techniques progressively build upon previously learned techniques. Scales Scales form the basis for other musical techniques. Student may study major and minor scales as well as modern scales, such as the whole-tone and octatonic scales. A scale consists of patterns of half steps and whole steps. These whole steps and half-step arrangements will be different for each scale. Scales are musical techniques that can help a performer to play faster and more accurately, and make learning new pieces easier. Chords Chords require knowledge of major and minor scales. Chords come in several different forms that affect the sound. Triads consist of three notes spaced a third apart and classified as major, minor, augmented and diminished chords. Seventh chords build on triads and have an additional no...

Similarities of Classical and Baroque Music

Music has evolved through the centuries and undergone drastic changes. One of the most significant transitions was from the Baroque to the Classical period of music. In this paragraph, I will compare and contrast some of the main features of these two styles, such as ensembles, instrumentation, and counterpoint study. The Baroque and Classical periods of music have many similarities. While the style of music changed drastically, certain key elements remained the same between the two styles. Composers in the Classical period sought to simplify music and create clearly audible musical lines. In contrast, composers from the Baroque period were interested in creating complex and highly ornamented musical lines. The Baroque period occurs from approximately 1600 to 1750, and the Classical period extends from 1750 to 1820. Ensembles Ensembles are groups of musicians that perform together. Both the Baroque and the Classical period had similar types of ensembles, such as operas, orchestras, str...
