You can change the footage interpretation just like with any other clip. However, since AE is terrible at audio processing and such procedures will affect pitch and sampling, you may want to consider properly converting and time-stretching your audio in Audition or another such software.

No, but there was a panel in after effect 

if we change the frame rate of audio 

like if we change the frame to a 20 FPS rate the Audio will get slower

if we change the frame to 60 fps the audio will go faster

I forgot the name of the panel could u mind tell me the name

I am pretty bad at explaining

i hope u understand 🙂

Of course you can play around with the Preview panel settings, but what good does this do for your project? The changes there are not persistent and really only affect the preview. All the same you can of course apply time-remapping and time-stretching to audio files and AE will resample them.

Please, I beg you - speaking as a sound mixer & mastering engineer who also happens to create Optical discs - never, ever time stretch audio unless there is absolutely no choice at all as it will inevitably introduce artefacts from this process.

Thankfully there is a better approach, and that is to resample the audio whilst leaving the DAW at the project sample rate.

For example - and you need a DAW that can handle this - if your project is at 48k (and for video it should never be at any other rate except possibly 96k) and the audio is playing out too fast, find out what percentage it is running too quickly at and resample the audio to an accordingly lower sample rate. So, if it is running 4% fast, decrease the sample rate by 4% - this will slow it down - and export at 48k. You may need to adjust using trial & error, but you will be in the right ballpark & there will be no DSP artefacts from Time Stretching.
