Poor sound quality when using the pitch shift effect. #723

Closed ghost closed 2 years ago

ghost commented 4 years ago

Good day to all! I use the application mainly only to lower the pitch of all audio streams on a PC with Linux (openSUSE with KDE) by 32 cents so that the music goes into the A 432 Hz pitch. And I noticed that the quality of sound conversion leaves much to be desired ... This is especially noticeable in music and speech programs when viewing content on YouTube, and this manifests itself as a slight tremor of sound during speech inserts and when one note lasts for a while ... I think that the pitch shifter effect algorithm in your program is rustic. So I want the quality of the conversion to be much higher. I compared the conversion quality in your program with the sound conversion quality in the Foobar2000 player using the appropriate DSP plug-in, and in Foobar the sound is very good. I really want your pitch shift algorithm to be better in your program, so that the quality improves. When I researched this question, I stumbled on this material on the Internet https://github.com/tomszilagyi/tap-plugins Perhaps something from there would be useful for your program? Thank you!

Okay, so we can finally close this issue.

When the template will be updated on weblate, I will add the new translations.

In the next week I could also add the new features in the documentation.

I agree. It is as good as it can get.
