| <p>Essential Tricks for Enhancing the Quality of Your Generated Audio</p> | |
| <p>1. Try to use 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". This can make sure AudioLDM 2 understands what you want.</p> | |
| <p>2. Try to use different random seeds, which can affect the generation quality significantly sometimes.</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, such as 'mummy'.</p> | |
