Project 1 - Exercise 2

Audio Shaping

Instructions

Record your own voice for 5 seconds for Exercise 2 submission.

  • Voice of phone call.
  • Voice coming from inside of the closet.
  • Voice of toilet/bathroom.
  • Underground cave.
  • Alien/ Orc voice.



Process Work

I recorded a 5-second audio clip, and Figure 2.1 shows the original waveform.

Fig 2.1 Original Voice

1. Voice of phone call

To create the effect of a phone call voice, I applied a high-pass filter to remove low frequencies and added a slight distortion to simulate the compression typically heard in phone audio. I also reduced the overall frequency range to mimic the limited bandwidth of a phone line. Figure 2.2 illustrates the modified waveform and spectral analysis for this effect.

2. Voice coming from inside of the closet

To simulate a voice coming from inside a closet, I applied a low-pass filter to muffle the sound and reduce high frequencies. I also added a slight reverb effect to create the impression of a small, enclosed space. The overall volume was reduced to further enhance the muffled quality.

3. Voice of toilet/bathroom

To simulate a voice coming from inside a closet, I applied a low-pass filter to muffle the sound and reduce high frequencies. I also added a slight reverb effect to create the impression of a small, enclosed space. The overall volume was reduced to further enhance the muffled quality. Figure 2.3 shows the waveform and spectral analysis for this effect.

4. Underground cave

To create the effect of an underground cave, I applied a long reverb with a decay time of several seconds to simulate the vast echoing space of a cavern. I also added a low-frequency rumble to mimic the deep, resonant qualities often associated with underground environments.

5. Alien/ Orc voice

Figure 2.6 displays the waveform and spectral analysis for this alien/Orc voice effect. The resulting sound is distinctly non-human, with a deep, menacing quality that effectively conveys the otherworldly nature of the character.

Experience

Through this audio shaping project, I gained valuable hands-on experience with various audio effects and processing techniques in Adobe Premiere Pro. Working with different acoustic environments and voice modifications challenged me to think creatively about how sound behaves in different spaces. The process of experimenting with filters, reverb, and pitch shifting helped me understand the technical aspects of sound design while developing my artistic judgment.

The most challenging aspect was achieving realistic acoustic simulations, particularly for the cave and bathroom environments where multiple effects needed to be carefully balanced. Through trial and error, I learned how different combinations of effects can create convincing spatial impressions. This exercise significantly improved my understanding of audio processing tools and their practical applications in sound design.

Observations

One key observation was how different acoustic environments require distinct combinations of effects to sound authentic. For instance, the phone call effect needed careful EQ and compression, while the cave environment demanded extensive reverb and low-frequency enhancement. I also noticed that subtle adjustments often made more convincing results than dramatic effects, particularly when simulating natural spaces like bathrooms and closets.

Findings

Through this project, I discovered several key findings that will inform my future sound design work. First, the importance of reference sounds in achieving realistic effects - studying real-world acoustic environments helped create more authentic simulations. Second, the value of layering multiple subtle effects rather than relying on a single dramatic one. Finally, I learned that maintaining consistent audio levels across different effects is crucial for professional-quality results.
