PitchShift Effect

[weow147]

Does PitchShift use RingBuffer by default or do i need to specify it somehow?

On a related note, i'm getting a warning with shift values less than 1.0 with i2s buffer settings:
DEFAULT_BUFFER_SIZE = 256
I2S_BUFFER_SIZE = 256

PitchShift.h : 372 - phase allign failed: maybe the buffer is too small

My application is real-time DSP. any larger than buffer 256 and the delay is unacceptable.

The wiki indicates that the ringbuffer is free of flaws?

If you use the PitchShift effect class, you can see in the class documentation that it is using the VariableSpeedRingBuffer.
In the constructor you can indicate the ring buffer size!

Perfect, thanks!
