About Change audio sample rate and bitrate
Resample audio to a different sample rate, such as 44.1 kHz for music CDs, 48 kHz for video, or 16 kHz for speech recognition, and choose the bitrate for MP3, M4A, OGG and OPUS. Lower rates shrink files but cut high frequencies, since the highest usable pitch is about half the rate.
