| johmue | Anyone here experienced with rubberband for pitch shifting? | 12:20 |
|---|---|---|
| johmue | Realtime pitchshifting I mean. | 12:20 |

| johmue | Is there a usual way for a LV2_UI to access the sample rate? | 22:06 |
| rgareus | johmue: no. but a couple of unusual ways. | 22:18 |
| * rgareus mumbles something about lv2 parameter/features | 22:20 | |
| rgareus | johmue: for cases where I needed it, I passed it from DSP to GUI (using LV2 Atom msgs) | 22:20 |
| * rgareus continues mumbling ..lv2 option interface.. | 22:21 | |
| rgareus | then again Ardour does not supply the sampleRate parameter as LV2_Options_Option, nor offer any options when instantiating the UI | 22:27 |
| johmue | rgareus: thanks. I want to show the plugin's latency (in ms) in the gui. So maybe I let the DSP calculate it and pass it as a additional port to the GUI. | 22:30 |
| johmue | I have the usual latency port to report the latency to the host. But that's samples, not ms. | 22:30 |
| rgareus | johmue: what is the use-case? do you expect users of your plugin to know what the number means? | 22:31 |
| johmue | rgareus: If I'm the user, yes? | 22:32 |
| rgareus | j:) | 22:32 |
| johmue | It's kind of a harmonizer plugin, which pitch shifts and delays, mixes the results with the dry signal and pans in the stereo panorama. | 22:33 |
| johmue | Rubberband reports a latency, then I substract this latency from the delay the user sets. | 22:34 |
| ssj71 | sounds familiar... | 22:34 |
| johmue | Finally I delay the dry signal to align it with the wet signal. | 22:34 |
| johmue | This final delay I report to the host, and also want to indicate it in the GUI. | 22:35 |
| johmue | ssj71: Is there a plugin that does just that? | 22:35 |
| ssj71 | ssj71.github.io/infamousPlugins/plugs.html#lushlife | 22:36 |
| ssj71 | johmue: but its mono-phonic | 22:36 |

| johmue | ssj71: Will take a look. | 22:41 |
| johmue | Mine is https://github.com/johannes-mueller/harmonigilo | 22:41 |
| johmue | First try to make a plugin. | 22:41 |
| johmue | Need to sleep now. Thanks @all. | 22:41 |
| * johmue out | 22:41 | |
