[LAD] [SOLVED] libsamplerate: src_simple issue: sign error perhaps?

Ah, output and input samplerate got twisted. I didn't think and followed the
documentation of libsamplerate.
In the section on the SRC_DATA structure it says:
"Finally, the src_ratio field specifies the conversion ratio defined as the
input sample rate divided by the output sample rate."
In the main section of the src_simple documentation it's clear though:
"src_ratio : Equal to output_sample_rate / input_sample_rate."

If only I could trade the fancy cars
For a chance today,
it's incomparable <3
