Kdenlive

The next major release of Kdenlive brings a 300% performance boost for generating audio thumbnails, along with higher-resolution waveforms for greater precision and a refactored sampling method that accurately renders the audio signal. This remarkable work was done by @etiandre and was made possible thanks to your generous contributions to our fundraiser campaign.

Three audiowaveforms compared. The top one shows the old method used being generated. The middle shows the new more accurate method. And the last is a reference for comparison of an audio waveform generated by audacity.

That's a shocking improvement! I imagine the better renders are also as impressive when exporting your mix and seeing the master bus limiting. Nice work!

@kdenlive @etiandre @kde Oh, I thought the image is just a scaling issue. Turns out the previous way unintentionally showed an aliased version of the signal. I continue to be surprised by intricacies of signal processing...

@kisaragi_hiu @kdenlive @etiandre @kde That's what I thought too!

But I'm just learning about all this video making stuff. I've found kdenlive to be really useful.

@kdenlive @etiandre @kde I remember waveform generation once took several minutes per hour of video and it was just a blocky line. It's much better nowadays and it's great to see it getting improved even more 👍
