Do you mean as a time-scaler or as a pitch-shifter?
WSOLA can and does work real-time in a pitch-shifter. But a time-scaler can't
be real-time whether it's WSOLA or a phase-vocoder. Because a real-time
process requires the output to process the input indefinitely without the input
and
Hi,
>From what I understood, WSOLA is algorithm that should work on Time domain.
Pitch shifting is a technique that should work on Frequency domain.
Thus, I don't understand your answer.
Could you explain in a more details what I need to do ?
Thanks,
Alex

WSOLA is an Time Domain algorithm, Pitch shifters can works in time domain
too, there are some ways to do this...
WSOLA is just one time-scaler, but you can pitch shift combining WSOLA and
Resample:
- Change the time using WSOLA (ex. time scale by 2.0)
- Use some interpolation(ex. resample scale
Hi,
My input is microphone. Then , I need the second option.
Could you give me reference with example and code so that I can understand how
to implement it ?
Thanks,
