teekay / waveformtimeline Goto Github PK

Was wondering if you would be interested in a UWP version of your control? I can help the process along, I just don't have the time to do all the work. That said, I can bootstrap most of the UWP side of things.

The start and end cues (see the Curtains component) are typically set by the DJ. However, one might also want to update them from code, e.g. by analyzing the leading and trailing silence in a track.

Currently, if one were to make such change, it would not propagate to the UI.

I'm having doubts on how to implement the contracts.
For example:

• IAudioWaveformStream's ctor requires an IObserver<float>, what should this stream of floats represent?
• what should IAudioWaveformStream.Waveform(int resolution)'s method's implementation do?

It would be very useful if you could provide a sample app :D

Thank you in advance

Hi! Thank you for making this project available, it's been a real life saver so far. I had to make a few tweaks here and there, but nothing major, everything works very well and the samples were a great starting point for integrating this component into my NAudio-based app.

Well, except this one thing. The timeline works fine when the waveform at the current resolution exceeds the available rendering width. And this is pretty much always the case for songs. Those are zoomed out automatically to fit within the available space.

But when it comes to shorter audio clips, like samples and sound effects, which are in the order of a few seconds, everything kind of breaks:

• The timeline stops working, only occasionally showing the 00:00 mark and no other numbers, even when the audio is longer than 1 second.
• The waveform is not stretched to fit, and is barely visible at the default resolution of 8000
• The semitransparent overlay that indicates the current playback position desyncs with the waveform, always going from the leftmost point to the rightmost point of the viewport even if visually there's nothing there

I've tried to guesstimate this scaling factor with scarce results, as I'm not even sure where I should be doing the calculation unfortunately...

I've also tried to just zoom in, but the same problem persists because it's scaling the entire viewport, including the silence at the end, so the playback indicator desyncs even more.

These are useful when the DJ wants to specify the start / end times, but make no sense without any track loaded
