Re: [ecasound] LADSPA latency ouput value SOLVED

Hi,

It works ! Thanks you very much, I can manually offset the output file.
The latency unit is a number of sample (220 sample in this example).

So a simple sox call make the sync_out_file.wav really sync with source
file :
sox in_file.wav sync_out_file.wav trim 220

Best Regards,
Julien.
