Essential Tricks for Enhancing the Quality of Your Generated Audio
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.
2. Try to use different random seeds, which can affect the generation quality significantly sometimes.
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'.
