ตัวแปลงไฟล์ออนไลน์ฟรี APE เป็น WV

This is a proprietary format (with a paid license) developed by Matthew T. Ashland. Sound is stored without any loss, but the format isn’t too common because of license restrictions and because the official codecs works only on the Windows platform.

WavPack lossless audio compression. Note that, when converting .wav to this format and back again, the RIFF header is not necessarily preserved losslessly (though the audio is).
