How to time shift and not effect pitch
I have the EVAL board and would like to slow down live audio or time shift, using a 10k POT to control how slow.
I am new to SIgmaStudio and have tried using ChatGPT but it seems out of date. I was wondering if anyone has any knowledge of this and how it could be achieved.
The instructions given are:
An input block to capture real-time audio.
A delay (buffer) block to manage the incoming audio.
A resample block to control playback speed, linked to the ADC input connected to the potentiometer.
A windowing/crossfade block to maintain pitch while slowing the audio.
Finally, an output block to deliver the time-stretched signal to the line-level output.
I am unable to find these blocks in the software tree.

Please find the attached project and see if it works for you as intended. In this project, a pot is used to control the delay time. It was Bob's project that I took it from this post. You can see the original post in that link.

You can also look at this post for delay-based pitch shifting, a project is also attached in that thread.

There may not be a single block that does all this for you but there are multiple ways to make an algorithm, usually using basic building blocks like above projects. You have all the basic blocks in the library that you can use to make your own algorithm, there are a lot of post and project available in the forum, you can search the forum for answers.

Thank you, I will test this out.
Any SigmaStudio freelancers out there by chance?
