Overlap adding two signals

[Chaitu86]

Hello all,

I want to overlap-add two signals so as to have smooth transition at their boundaries.
Each signal is 30 samples and the idea for the overlap-add window is to use a linear ramp.

Can someone tell me how to do this in Matlab? I am quite new to signal processing :???:

Many thanks

Hope it you have C code then you can do in matlab.
Look in FFmpeg source code where in G.711 PLC code uses over-lap add is used.

Hi

Thanks. I looked for the source code of G.711's PLC implementation, but couldn't find it.
Could you provide me with a link?

Many thanks
