@Gustavo-L-Conte I think Jonas already answered a topic like this in the past, but I'm not entirely sure. Either way, I think captchas are a good idea to control spam.

Just passing by to say that since last month WakkaQt gone v1.0! WakkaQt is a multiplatform karaoke application built with C++ and Qt6, designed to record vocals over a video/audio track and mix them into a rendered file. This app features webcam recording, YouTube video downloading, real-time sound visualization, and post-recording video rendering with FFmpeg. It automatically does some mastering on the vocal tracks. It also has a custom AutoTuner class I programmed called VocalEnhancer that provides slight pitch shift/correction and formant preservation. more info here: https://gu.pro.br/wakkaqt/ Merry christmas ppl
