I claim (!) that most of the longtime HA followers wouldn't encode with less than 160kbps-192kps if it's about 1-time-encoding for their lossy-archive..
I've just learned all about Opus and I'm planning to do a massive migration previously from AAC to Opus of about 2000 tracks from my library. Seeing that Opus 1.3 is coming, should I be waiting for 1.3 or the recent stable version a way to go?
Well, it's always personal taste where to put the sweet spot.
But Opus @128 kbps has a higher probability of encoding even hard to encode tracks fine than AAC @128 kbps.
For regular music usually everything is fine @128 kbps even with a good mp3 encoder.
So any suggestions or obsrervations for 1.3 beta?
Until now there isn't much help from you for Opus beta (actually no help at all). So any suggestions or obsrervations for 1.3 beta?
but being you tested Opus @ 32kbps, which I can tell sounds noticeably worse than even the 48kbps+ range, would I be correct in saying that any improvements the developer is attempting to make at those low rates would be difficult to detect between v1.2.1 and v1.3 beta? ;
because if so, it makes me wonder how one improves things if someone don't have any pretty reliable information to provide the developer. or is there simply some people they know and trust to make these observations at those low bit rates etc?
Anyway I have a feeling and I can be wrong but Opus 1.3 can be the last serious release. Audio codecs are pretty done today. AAC, MP3 and Vorbis are already overdeveloped and their developments are abandoned at this point. Add to it that we won't see newer generations formats (xHE-AAC, 3DA) in internet community anymore. Development of video formats is much more interesting ($) at this point. It's pretty close to good bye.
Actually Opus has a big limitation that can make its low bitrate quality improvement to stagnate beyon Opus 1.3, is that it is a low delay codec, but is very posible that a non low delay codec based in Opus can inprove the low bitrate quality furder.
Isn't the delay configurable at encoding time? opusenc uses a very high delay setting by default. Only realtime encoders (for voice communication) use a low delay setting. Right?
So would an opus variant with higher frame sizes and longer look ahead make sense for applications where both don't matter or it seems like we have exploited already it's limits as a format?
Encoding at 20.0x max using Foobar 1.4 beta! If Im not mistaken it used to be around 100.0x. Much slower compared to FhG AAC @ 70.0x max.
