<div class="acknowledgements"> <p>Essential Tricks for Enhancing the Quality of Your Generated
Audio</p>
<p>1. Try using more adjectives to describe your sound. For example: "A man is speaking
clearly and slowly in a large room" is better than "A man is speaking".</p>
<p>2. Try using different random seeds, which can significantly affect the quality of the generated
output.</p>
<p>3. It's better to use general terms like 'man' or 'woman' instead of specific names for individuals or
abstract objects that humans may not be familiar with.</p>
<p>4. Using a negative prompt to not guide the diffusion process can improve the
audio quality significantly. Try using negative prompts like 'low quality'.</p>
