Maybe I'm just googling the wrong thing but what's Unreal's default audio sample rate? 44.1kHz or 48kHz? Silly simple question but thanks for helping out!

    \$\begingroup\$ 44.1 and 48kHz are SAMPLE rates, not bitrate. A sample rate has to do with recording, and frequencies. Bit rates are numbers like 128kbps, and has to do with playback. (Simplifying both a lot) \$\endgroup\$

Unreal Engine 4 currently supports importing uncompressed little endian 16 bit wave files at any sample rate (see the chart below). For best results, it is recommended that sample rates of 44100 Hz or 22050 Hz be used.
