Highest Frequency Shown by Spectral Frequency Display?

I am working on a project where I have to analyze 3 video files and 2audio files' frequencies simultanously; all of the wav files have information up to 98kHz. 

 

Does the spectral frequency display go high enough to display 98kHz?

If so, is it possible to view 2 spectral frequency displays with 3 streams of video all playing simultaneously?

 

Any help is greatly appreciated 🙂

The spectral frequency display limit for any given sample rate is its Nyquist value - and that is half of the rate expressed as Hz. So a 44.1k sample rate will display a response up to 22.05kHz.  What is the sample rate of your wav files?

 

The answer to the second part of the question is a simple 'no', I'm afraid. You can only display a single video or audio stream at any one time in Audition.

The sample rate of the wav files is 192k. 

 

I have a seperate question that you may likely know: although not being able to view simultanouesly, is it possible to:

1. Annotate/mark at specific timestamps on audio files?

2. View these annotations at corresponding times on video streams (assuming they are time-synced)?

 

Thank you for all of your help 🙂

If your sample rate is 192k, then the highest frequency that will be displayed is 96kHz.

 

If you hit F8 at any point on a wav file, a marker will be placed at that spot. What happens as far as displaying them rather depends upon how you are playing this back. In Audition they will be displayed on the waveform itself, but you will have to devise a way of synchronising this with the video.
