This week's lesson was aimed at going through the unit outline and understanding what is required within all three project and learning journal submissions. I was physically not in class this week, but I ensured to follow up on the content learned and keep up to date through the use of the powerpoint slides and resources available on moodel.
During this week's lesson, the main objective was to go through the requirements for Project One and the associated glossary of key terms that are required to be used within Project 1. All the required terminology can be found under the project one tab located on the AUD175 page.
At the beginning, I personally found identifying each of the different types of sound waves and the way in which they can be applied a challenge, as it was the first time that I spoke and reflected on the different types of waves in detail. However, I personally feel that this session was a great learning experience as it gave me an opportunity to deepen my knowledge and skillsets around sound waves. This task will aid project 1 by allowing us to go into greater depth with our project details.
My next steps before next week will be to further analyze the project 1 brife and have a look at sample projects to get an understanding of what content is expected to be developed and included.
In regards to this week's transfarable skills learnt and were rated best on were critical thinking and discovery. The reason why I feel this was due to the fact that we were required to critically think and collaborate on research on sound waves and the different keyterms assigend for project 1's track descriptions. The practice of these transferrable skills will help with the development of project 1 and the completion of the research task.
Waveform: This is simply an image that shows a recording of an audio source. It shows amplitude changes over a period of time. Waveforms give producers a visual idea of what's being recorded. This let’s them judge if there are changes that need to be made to the recorded audio (Techterms, n.d).
Wavelength: In simple terms, this is the size of a wave that is measured from one peak to another. If one were to imagine, it mainly looks like a wave. It is also the distance the crest from one wave to the next. In terms of distance, two peaks are usually 1 meter apart. When someone wants to find the wavelength of any sound, this would be the formula that would be used: wavelength=speed/frequency (Acoustics Today, n.d).
Spectrogram: Spectrograms are mainly audio pictures, however they are not waveforms as spectrograms cannot be altered or changed. This means that the brighter the color’s figure gets, the more concentrated around the specific frequencies. This gives us an understanding of the audio’s shape and structure. ( Towards Data Science, 2021).
Amplitude: By definition, this term is the measurement of change over a period of time. In an audio setting, it’s the change of the volume of a recording from one point to another. An example of this is a volume tuner on a radio player. By changing the volume, the amplitude is either increasing or decreasing by some amount. This shows you how loud or soft a sound is (BACKTRACKS, n.d).
