I’m struggling on slowing the audio down without the spectrogram distorted. I guess the built in Audio Spectrum has a max_freq parameter set to 22050 and it’d be so easy if I could change the parameter…

I didn’t know the cumulative render. I will check it out.

Thank you so much!

Thank you for your comment.

What I need is just to represent the ultrasound spectrogram precisely either in 2D or 3D, and I thought both could be generated by using Audio Spectrum. For example, I could possibly change the color of the spectrum when the audio level exceeds a certain threshold and set the height zero, so that 2D image could be generated.

Is there any other way to generate 2D spectrogram in AE such like in Audition?

Preserving the spectrogram look is the most important for my project. I’ve tried slowing down and pitch shifting using Audacity, Adobe Audition and another software, but unfortunately the spectrum was somewhat distorted.

Thank you for the comment. Slowing down is an option, though I want to play the movie at real time in the end.
