Learning in class
From this lesson I learned that the field recording equipment l could use for my project are Zoom H3 VR or Sennheiser Ambeo.
Where the speaker in the m108 studio is the octophonic ring, it is a form of audio reproduction that presents eight discrete audio channels using eight speakers.
We have then experienced recording using the octophonic ring using signwaves and squarewaves. We have tested in various tempo and dynamic directions. During this process, l observed the impact of distance and how spatial created on microphone recording. Especially for ambeo H3 due to its multi capsules that capture the sounds from many different directions, therefore we have run around in a circle to experiment the sound changes in ambeo H3, and this is how the stereo sound is being collected.
Idea developments:
From the experiment on ambeo H3, l consider the idea for album intro could be develop with more spatial designs, instead of using only one speaker, l could create different tracks in various speakers, like how we use the octophonic ring, we can think of the direction, where does the audience face, and what impact does it create for the audience, etc. For example, if l want to create an effect of a forest, l could make each sound in various layers and place them in different speakers and spots of the room so It overlap each other while creating an immersive effect on the audience.
