s argument: higher steps give higher quality audio at the expense of slower inference.
The length of the predicted audio sample can be controlled by varying the audio_length_in_s argument.

How to load and use different schedulers
	
The AudioLDM pipeline uses DDIMScheduler scheduler by default. But diffusers provides many other schedulers
that can be used with the AudioLDM pipeline such as PNDMScheduler, LMSDiscreteScheduler, EulerDiscreteSched
