Changing the sampling rate turns lossless into lossy

[betteraxin]

A 48000hz FLAC lossless file becomes lossy after being converted to 44100hz, But using Adobe Audition to do the same operation is still lossless，I think this may be a problem with the FLAC encoder parameter settings，Hope it can be solved. Thanks.

Это работа фильтра подавления алиасинга, настройка ресемплера.
Если не резать частоту - будут возникать паразитные частоты, которые вы не увидите на картинке, но они будут ухудшать звук.

I don't think so. I have professional Speaker and I can't hear any difference between them. I used two professional music editing softwares, Ableton Live 12 Suite and FL Studio 21, to do the same operation. The results are the same as those obtained using Adobe Audition 2025. They are still lossless. See the spectrograms after they are converted. Ableton Live 12 Suite and FL Studio 21 are professional music production software. I believe their developers should know this.

What resampler settings you used in AIMP for these results?

Just change FLAC 48000 to 44100, other parameters are not changed. I uploaded the original file and the files converted using four softwares
