• Introduction
Technology has paved a way for us to appreciate music in a more personal and convenient ways. Gone are the days that we need a huge investment, wide space and a stationary action for us to appreciate quality music: the CDs and walkmans that render us immobile, the lack of good earphone technology, and even the low-quality amplifiers have been gone.
A more interesting part in the technology that incorporates sound and music, however, is on how studios and computers facilitate recording and compressing sound without compromising quality. Indeed, without the use of compression technology, sound recordings will take up much bigger spaces than the compact files that we enjoy today. It is to be recalled that what was once a 12-15 track CD is now conveniently able to store hundreds of tracks due to compaction. Moreover, without sound recording, there is no way that we will be able to hear tracks of our favorite bands without attending to their concerts.
An understanding of hearing, sound and its conversion into digital data is essential to properly utilize sound recording and playback facilities. It is also helpful to know the essential properties of digital audio in order to maximize sound editing techniques.
• Digital Sampling, Filtering and Compression
a. Sound Production and Digital Sampling
Sound is produced through variations in air pressure. Stringed instruments, mainly guitars, use vibrations to produce sounds. Electronic devices use loud speakers to facilitate the production of sounds (Marshall, 2011). Our ears are sensitive to the changes in pressure, thus, we perceive them as sounds.
Computers, however, cannot process analog sounds. There is a need to convert the sounds into discrete, mathematical data (M...

...als into frequency domain signals so that there is an easier way to process signals. Frequency domain filters are used to perceive beats, apply reverb, and add or subtract frequencies. Auditory masking and filtering is used in order to compress the sound file without compromising quality.
The beauty of digital audio is mainly reliant on the processing of waves and frequencies. Through further study, more and more compression techniques and higher quality file formats will be attained in the future. Truly, the music experience will get better and better as sound technology becomes more and more sophisticated.

From the Kinetophone to the Vitaphone, the sound-on-disc format dominated the pioneering stage of sound in movies. For the first time ever, people were able to hear sound synchronized with the images on the screen, and the revolution had begun-the talkies were here to stay. It was the sound-on-disc format that helped create many of Hollywood’s “talkie” classics, including The Jazz Singer and The Singing Fool. However, another format, sound-on-film, would soon take reign of the talking motion picture movement, as the audience and the exhibitors started to become more demanding as technology was slowly improving. Sound-on-disc was simply beleaguered with too many technical and economic problems to continue to stay relevant. Thus, the competing sound-on-film format eventually became widely-accepted in the motion picture industry and is used even to this day.
An audio production console is generally used for the production and post-production of music and films. They are designed to give the engineer the ability to mix different sounds simultaneously and alter the dynamic processing; such as equalization, reverberation, compression, and delay. There are two different types of consoles called analog and digital consoles. In an analog console, all of the sound inputs are physically wired to output jacks in a speaker. In a digital console, all of the analog signals are converted to electrical signals which can be stored on a computer or disk. The number of features on these consoles will vary depending on their purposes.

When it comes to recording in a modern day environment DAW’s (digital audio workstation) are an essential piece of equipment if professional standard results are desired. Although DAW’s are considered a modern technological advancement the first attempt at a DAW was in 1977 and it came from Dr. Tom Stockham’s Soundstream (See references for full description) digital system. It had very powerful editing capabilities and for its time a very advanced crossfader but was still primitive compared to today’s standard. At this moment there are 100’s of DAW’s on the market but arguably there some obvious leaders. Avid’s Pro Tools has been the go to DAW for any professional studio for the past 20 years and although there have been rumors of Avid going out of business and the features in Pro Tools becoming dated, Pro Tools is still a viable option for studios worldwide. Logic Pro has risen to the fore-front of the industry in recent years due to its easy to use interface that is possible of producing professional results. Ableton Live strays away from a hardware instrument music environment to cater for electronic music users. Audio to MIDI is a main focus along with the critically acclaimed Max for Live used for live performances by many current EDM artists. Each individual DAW has its own pros and cons and comparing these can highlight which DAW is the best for what task.

There are a great number of applications for Digital Signal Processing and in order to better understand why DSP has such a large impact on multiple aspects of society, it helps to better understand the wide variety of applications it can be used for. Here we will briefly look into the following applications of Digital Signal Processing and their uses; speech and audio compression, communications, biomedical signal processing and applications in the automobile manufacturing industry. Li Tan [1] goes into detail with each of these applications in his book, Digital Signal Processing, and explains how each are used on a daily basis.
This is a music lesson plan designed to incorporate technology into music. The idea is to let students learn about their favorite music while learning about today’s technology.
To record the instruments, music producers have tools and equipment such as microphones, compressors, limiters, effects and other useful tools in the recording studios. All these tools are present in the recording studio. Thus, music producers may use them to their advantage to record an
Through out the history of music, acoustics have played a major role. After all if it were not for acoustics the quality of sound that we know today would not exist. The word acoustics comes from the Greek word akouein, which means, “to hear”(Encarta Encyclopedia). Since music has to be heard in most cases for enjoyment, acoustics obviously take on a very important role in the pleasure that music brings to the ear. Acoustical architecture and design are two key elements in the way music sounds. For example, an electric guitar played in a concert hall would sound very different compared to the sound produced in a small room. These differences can be explained by the acoustical design of the room and the reverb created by both the instrument and the room in which it is played. These differences signify the importance of acoustics in music.
What distinguishes sound waves from most other waves is that humans easily can perceive the frequency and amplitude of the wave. The frequency governs the pitch of the note produced, while the amplitude relates to the sound le...
Trigonometry is the branch of mathematics that is based off on the study of triangles. This study help define the relations between the different angle measures of a triangle with the lengths of their sides. Even though trigonometry is the study of triangles, it is mostly used to study right angled triangles with the six functions: sine, cosine and tangent, and their reciprocals cosecant, secant, and cotangent. These functions are made by the corresponding points to the infinite number of angles that are present when continuously rotated in the unit circle. Because of this, each of the trigonometry functions has a tendency to repeat itself after every complete rotation around the unit circle. (Pierce) Since everything in math can be applied in real-life situations and problem, trigonometry has many applications in the real world as well, such as in architecture, astronomy, and in music. Likewise, the purpose of this essay is to further explore and research the real world applications of trigonometry in music. Music is a subject that intrigues me because it is like a whole other language on its own. It is very unique with its notation system and different styles, just like in literature. Thus, I wanted to learn more about its background so it can help me to better understand its concepts, like how the human ear receives music and how it can interpret high notes and/or low notes when it is by itself or when it is harmonized with others.
