When you download audio files from Genny, it will either be in 22.1kHz or 24 kHz. To resample into higher or lower sampling rate, you can use free software like Audacity to do so.
Here are the step-by-step.
1. Open Audacity.
2. Load your audio file into Audacity by drag and drop, or by going to File>Open>choose file.
3. You will see Project Rate (Hz) menu on the bottom left corner (I’m using a Mac. Audacity UI on PC might be different, and also depending on Audacity version.) Click on it, and change the sampling rate to the desired rate.
4. Go to File>Export>Export as WAV to export your audio file!
