無料オンラインAV1からWVへのコンバーター

AV1 is a new open codec developed by Alliance for Open Media consisting of companies that produces electronics and develops web browsers. The codec is aimed to send high-quality videos via the internet quickly and without losing the quality even when bandwidth is low. AV1 is more efficacious then today's most popular video formats because it uses future compression technology.

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).
