FAQ: How do I convert audio files into supported WAV files in Audacity?

[Jono]

For compatibility with Experiment Builder, audio files must be in signed 16-bit WAV format with a sampling frequency of 48 kHz (48000 Hz) or lower. Audacity, a free and powerful open-source audio editor, makes it easy to convert your files to this format. ?

You can download Audacity from its official website: https://www.audacityteam.org/
