This is truly a representative of the old internet: somebody codes up the best AAC encoder ever, and the first response comes from some admin, and it's some bickering about 48Khz vs 44Khz.
It’s not that cynical. The author didn’t test on the most common rate in use, so it would be ludicrous for any serious project to wholesale replace a decades old working pipeline with it. It makes perfect sense to wait till due diligence is done.
>>...use 48Khz if you want the best quality.
>Yet most of the worlds audio is 44KHz...
