Targeted TD-PSOLA fails

[bozothegrey]

Hello, I am trying to follow step by the step of the tutorial. My input is a single channel audio file.

Small edit to the tutorial:
I assume it should be
x_3keydown = tsm.tdpsola(x, sr, src_f0=f0_crepe, **tgt_f0**=f0_crepe * pow(2, -3/12), p_hop_size=441, p_win_size=1470)
and not target_f0.

The issue is that
tsm.tdpsola(x, sr, src_f0=f0_crepe, tgt_f0=f0_crepe * pow(2, -3/12), p_hop_size=441, p_win_size=1470)
fails with this error.
Is it because the input is single channel ?

Let me investigate a bit more. I will revert if still an issue.
