Record sample sound and convert them into MP3 or OGG to reduce download size.
Warning: compression bring distortion to wave shape and you may notice clicks in looped samples. You need to change loop start/end to avoid clicks.
Warning: Of course, you can use the original uncompressed .wav files with the maximum sample rate and stereo. But this will increase the download size by 20-30 times.
