Hi all
Today foobar2k released the free encoder pack containing opusenc already which made me try out this.
As I don't understand too much spectral graphs I see the high cutoff range is set to 20kHz by 96kbps which makes me think the codec's ambitions are really high, and I'm really impressed about the sound
I have several more questions:
Is the average vbr mode fixed to 96kbps or can it be increased yet higher?
What does the complexity option affect when not the bitrate (what's the advantage of complexity <10)?
What bitrates of Vorbis, AAC and MP3 (all in VBR modes) are counterparts to Opus at complexity 10 (approximately) as for sound quality?
Are Opus's chances to become more standard supported by wide range of hardware players higher than Voirbis's?
Keep on developing this great codec
