xHE-AAC : The Death of OPUS? 2020-12-30 20:40:27 You might have been waiting for better adoption for your dear codec OPUS in DAPs, Podcasts, Bluetooth, even as a VoLTE codec from your mobile carrier but guess what: instead xHE-AAC will see that adoption. As listening tests in this forum have proved it is already trading blows with OPUS in efficiency. And even the slight edge, going either way, wouldn't matter because again the adoption is going to be almost universal. So, back to the point, will OPUS still be relevant?
