[aubio-user] pitch detection frequency doubling

[Paul Brossier]

Hi Adam,

Sorry for the late reply.

One likely cause is that you are trying to feed a buffer of intereleaved
samples to the pitch detection:

  [ l1, r1, l2, r2, ..., ln, rn ]

Make sure you downmix the signal to mono before filling up the fvec you
pass to aubio_pitch_t.

Best, Paul
