v4.17 is out! And thanks for continually making such a great program.

EDIT: Holy Effin crap, forgot to add "-portable" to the exe... thanks for making a mess of my registry I guess...

I've noticed that you've been very on top of the Opus updates, which is appreciated. However, I noticed on a recent updated for Pazera here on the forums, they mentioned some optimizations for human voice:

New Opus encoder options: bitrate mode, the ability to set the encoding algorithm complexity, frame duration, low-pass filter, the ability to fine-tune the work of the encoder to process audio files containing music or recorded human speech.[source]

Do you have any functionality along those lines?

Opus is a hybrid codec: It uses SILK for speech encoding, and it uses CELT for music encoding, “switching between or combining them as needed for maximal efficiency”.

Nothing of that is really new; it is just how Opus has worked all along.

However, libopus v1.3 made some improvements regarding speech/music detection using an RNN (Recurrent Neural Network), plus some other improvements. libopus v1.3.1 was a minor (maintenance) update:
http://opus-codec.org/news/

LameXP currently ships with OpusEnc based on libopus v1.3.1, as released April 12th this year. There have been no relevant code changes since then, as you can see here:
https://git.xiph.org/?p=opus.git;a=summary

(Note that there have been a few fixes for the NEON optimizations after the v1.3.1 release, but these are irrelevant for Windows binaries, since NEON is used/supported on ARM processors only)

As far as "algorithm complexity" and "frame duration" are concerned, you can change these on the "Advanced Options" tab in LameXP, if you really want.

But there is hardly any reason to not use the maximum algorithm complexity and the default frame size. “Opus uses a 20 ms frame size by default, as it gives a decent mix of low latency and good quality.”

Excellent, thanks for the detailed breakdown

Excellent, thanks for the detailed breakdown

BTW: The automatic speech/music detection can be overwritten via the "--speech" and "--music" command-line parameters, but that is not normally recommended.

As much as I love this program, it's also one of the most obnoxious, annoying fucking things too, just now I'm getting a "Your version is a year old, time to check for an update" or whatever with some annoying unskippable Jeopardy music that plays... Like maybe release a new version then? Because my version is the latest (v4.17). While your at it, remove the Homer sounds too.

I have an old version as well that I expect has the same steps to disable the audio ...



For my part, I think LameXP is easily the best encoder available, keeping the encoders up-to-date are welcome and appreciated, and I don't have strong feelings one way or the other about the sound cues.
