| <li>You must provide an input audio and a target prompt to edit the audio. </li> | |
| <li>T<sub>start</sub> is used to control the tradeoff between fidelity to the original signal and text-adhearance. | |
| Lower value -> favor fidelity. Higher value -> apply a stronger edit.</li> | |
| <li>Make sure that you use an AudioLDM2 version that is suitable for your input audio. | |
| For example, use the music version for music and the large version for general audio. | |
| </li> | |
| <li>You can additionally provide a source prompt to guide even further the editing process.</li> | |
| <li>Longer input will take more time.</li> | |
| <li><strong>Unlimited length</strong>: This space automatically trims input audio to a maximum length of 30 seconds. | |
| For unlimited length, duplicated the space, and remove the trimming by changing the code. | |
| Specifically, in the <code style="display:inline; background-color: lightgrey; ">load_audio</code> function in the <code style="display:inline; background-color: lightgrey; ">utils.py</code> file, | |
