If you write uint16 data, when the wave data is played back, the audio is noisy and sounds distorted.

I think it is better to ask for a slice of []int16 to avoid this issue.

A work-around is to pack int16 data into the uint16 format before calling WriteSample16, like so:

uInt16Slice := *(*[]uint16)(unsafe.Pointer(&int16Slice)) _, err := waveWriter.WriteSample16(uInt16Slice)

Note: shifting the int16 samples into the range of int16 did not fix the problem. At first, I thought that I would just need to add -1 << 15 to each int sample to get the uint equivalent, but it is distorted as well.
