In depth
A closer look at AM Pitchshifter
The plugin works by running a single write pointer (monotonic) and 2 read pointers (pitchscaled) over a ringbuffer.The output is faded between the two readpointers according to the sine of the distance from the write pointer. The design is based on the mechanism of a mechanical pitchshifter The multiple of the output pitch, eg. 2.0 will increase the pitch by one octave. The order of magnitude of the buffer size. Small buffers will sound fluttery, large buffers will have flangy sounding echos.I recommend a buffer size of 3 for a reasonable compromise, with wideband material at around 48KHz. For drums you might have to lower it, and for voiced background noises it can go higher.
