And that should be the average value, not the minimum which can be achieved only during a small fraction of the time (or for unvoiced signals by forcing them to have a different delay than the average voiced ones). > No claim is made that the pitch is corrected within that time. Indeed, but that is not what I refer to. Assume for a moment that you are retuning 'up'. That means that the input is consumed faster than the output sample rate. So at some point, since you can't read past the end of input, you will have to skip back by at least one cycle of the fundamental frequency, which means the latency will increase by the same time. Latency is in fact changing all the time while retuning, and the only meaningful value is the average one. For a constant retuning ratio, the latency as a function of time will be a rising or falling 'sawtooth'. The fundamental difference between at1-0.8.1 and previous versions is that it will try to remain as close as possible to a well-defined average delay, i.e. minimise the delay jitter. > That delay has to be reported to the host. Of course. But that should be real value. Not some fake one dreamt up to look good. -- FA _______________________________________________ Linux-audio-dev mailing list -- linux-audio-dev@lists.linuxaudio.org To unsubscribe send an email to linux-audio-dev-le...@lists.linuxaudio.org
