Opus 1.1.1-beta

Hi, 1.1.1 beta is available

This is what is new:

The is a beta release for the upcoming 1.1.1. This release focuses on code optimizations, especially on x86, MIPS and ARM. The quality should be unchanged.


But this bete seems to break floating point integrity so only fixed encoder is provided:

Not sure what "floating point integrity" is supposed to mean, but as far as I can tell float works well. If not, then please report a bug.

Finally the problem is resolved. Floating point converter available:
(SSE optimized build, should work on any CPU)

Processor: AMD 8320 @ 4Ghz, turbo disabled.
These tests are just based on 17 mostly random tracks from Flac (16, 44.1).

Decoding - Using decoding speed test in Foobar2000:
-Flac - Decoding time: 1:26.264, 3726.529x realtime
-Opus 1.1 (130Kb/s VBR) - Decoding time: 4:46.300, 1122.651x realtime
-Opus 1.1.1 Beta (130Kb/s VBR) - Decoding time: 4:43.983, 1131.836x realtime

Encoding - 130kb/s:
1.1 Foobar binary using opusenc and the same 17 tracks combined into 1 flac (probably not a good way to test):
----------------------
      Encoded: 1 hour, 23 minutes, and 43.32 seconds
      Runtime: 2 minutes and 16 seconds
                (36.94x realtime)
        Wrote: 80960820 bytes, 251166 packets, 5026 pages
      Bitrate: 127.912kbit/s (without overhead)
Instant rates: 1.2kbit/s to 262kbit/s
                (3 to 655 bytes per packet)
      Overhead: 0.795% (container+metadata)
----------------------
1.1.1 Beta x64 using same method:
----------------------
      Encoded: 1 hour, 23 minutes, and 43.32 seconds
      Runtime: 3 minutes and 10 seconds
                (26.44x realtime)
        Wrote: 80927556 bytes, 251166 packets, 5026 pages
      Bitrate: 127.859kbit/s (without overhead)
Instant rates: 1.2kbit/s to 262kbit/s
                (3 to 655 bytes per packet)
      Overhead: 0.795% (container+metadata)

Hmm. That may be because of I used increased math precision and safe float point speculation, it might decrease the overall optimiizations.

Whoops, won't let me edit the last post again, anyways I redid the encodes using another method but similar results still.

Default (96kb/s) -
Encoding every file at once (saturating my cores) on the individual files and stopping timer when all had finished:
1.1 Foobar binary:
26.96 seconds (186.32x realtime)
-----------------------
1.1.1 Beta x64:
Runtime: 31.74 seconds (158.26x realtime)
-----------------------

Conclusion
Decoding speed for x86 on an AMD 8320 is slightly faster though could just be in range of marginal error. Encode speeds seem to have decreased quite a bit.

I've compared three opusenc.exe. I just used only one flac file, though.
My result is similar to Seren's one with AMD.

ps. I did manual conversion, and just only a single core is used.

Not sure where to post this really, Telegram uses Opus @~16kbps for recording audio messages. Really awesome open source secure messaging app that works everywhere.

A new 1.1.1-rc came out on the 23rd. Basically entirely speedups (mostly ARM) and a few bug fixes. No new quality changes.

Does anybody can build win binaries to test?

It works on XP after applying the hex edit described in the post I've quoted. Although the sequence appears twice at 0140H and 0148H.
It also requires MSVC2013 runtime.

Why the multi-megabyte dlls that only have one function called apiece?


Probalbly it calls only one function apiece, that's a shame ;( It's a feature of Intel intrinsinc. Maybe I could try do static but I'm afraid it would only result in not referencing Microsoft runtimes as I see nowhere static equivalent of libmmd and svml_dispmd ;(
