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,
Alex

WSOLA is an Time Domain algorithm, Pitch
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,
>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

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
