Opus vs AAC (endurance test)
using iTunes i've noticed that AAC is
very good at re-encoding own lossy sound.
let's test Opus!
neroaacenc.exe -q 0.75 -if 000.wav -of 001.m4a
neroaacdec.exe -if 001.m4a -of aac001.wav
wavdiff.exe 000.wav aac001.wav
Comparing 000.wav - aac001.wav...
Max diff: -17.3867dB
RMS diff: -33.0851dB
Mean diff: -32.4582dB
opusenc.exe --bitrate 512 "000.wav" 001.opus
opusdec.exe 001.opus opus001.wav
wavdiff 000.wav opus001.wav
Comparing 000.wav - opus001.wav...
