Title: Audio Stretching in Adobe Audition
Post by: BradleyJY15 on April 20, 2022, 02:46:02 PM

I taped a show with AUD mics->SD MP6, then had SBD->TASCAM DR-05.

I want to stretch the SBD source by a couple hundredths of a second.

How do I do that in Adobe Audition w/o a pitch correction (and killing the sound)?

Select resample in the time stretching module.

Is this the correct tool?

These are the settings that I am using and it comes out sounding terrible.

Not sure what else I need to do or what all the settings really mean.

When I run those settings and preview the audio it sounds good.

But I have processed it twice and it comes out terrible.

I will try again.

Maybe this will help: http://downloads.izotope.com/docs/rx6/54-time-and-pitch/index.html

I did a video on time alignment in Audition, check it out at https://youtu.be/MOz2GUdL_vw

For Audition CC, use the Stretch/Pitch module. Make sure you select "lock stretch and pitch shift (Resample)".

I've done a bunch of tests and the rebuilt time stretch algorithm in the Audition builds after CS5 are just not as accurate as Audition 3.0. I still keep AA3 for the time stretching as a result.

I bet turning off the vocoder feature would help for a straight time stretch/squash.


And yes, when you change the amount of time a file plays for, the pitch will change (probably microscopically)

Is anybody else having an issue with speed correcting causing borderline lossiness on spectrograph analysis? ???

I'm slowing down a tape that ran half semitone too fast. I used the iZoptope Radius option in the "Stretch and Pitch (process)..." tab. The hiss seems to appear less intact than in the original track, and tapers off when the music ends. To compare it, I used Audacity to see if it gave me a cleaner result and it does show the hiss being more intact (although losing everything above ~20.5kHz).

Each spectral display sample is displayed from Spek 0.8.2.3

Will have to do a WeTransfer link for full quality look sorry: https://we.tl/t-L0jFNfQJrP
