MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by Wombat -One simple and one with fast-math + AVX2 that doesn't do much for speed on my Ryzen 5900x.
You may give it a try.

3rd Party Plugins - (fb2k) / Re: foo_vis_spectrum_analyzer
Last post by Defender -Since we now have the ability to see "RMS" as text maybe it would be useful to also see "Peaks" as text. And to go further also "Peaks - RMS" - but what would that value be "equivalent" (sort of) of: momentary/short term DR (from the infamous plugin), momentary/short term PLR/PSR, momentary/short term LUFS, momentary/short term LRA or something else?
Isn't that already available in the modern Loudness Peakmeter plugin?

3rd Party Plugins - (fb2k) / Re: foo_vis_spectrum_analyzer
Last post by Case -Sorry @case but I'm not going to take your word for it. Removing the division causes all the test files from SOS to have a dBFS reading that is 3dB higher than their expected result. Even the tone://997 reference is wrong.It's not my word, that's the very definition of RMS: https://en.wikipedia.org/wiki/Root_mean_square#Definition.
You calculate the sum of values squared, divide by the number of values and take square root of that.
And removing the last division does not increase the result, I don't understand why you claim that. It causes the file labeled -20 dB to show -23 dB RMS, or -20 dB with the +3 mode enabled. And tone:// test is -3.0 dB / 0.0 dB.

Can you point me to some documentation or specs?

MP3 / Re: Low bitrate MP3 (+ unsupported bitrates)
Last post by Kraeved -lame --freeformat -b12 -mm --resample 11
Why do you keep pushing that devilish freeformat? Do you know many players that can decode it? MPV that utilizes mpg123 — yes. 1by1, AIMP, FFPlay, Foobar2000, MPH-HC, Resonic, Winamp, XMPlay, you name it, let alone web-browsers — no. It's an optional part of the spec, an experiment that has not received recognition if you will.
Which LAME version is recommended? (I didn't like LAME's sound color in my tries. I used Shotcut.)
Shotcut is a video editor, not an audio encoder. In case of exporting your project to MP3, it can utilize either LAME (libmp3lame) or MediaFoundation (mp3_mf) encoders of the bundled FFMPEG. By the way, they use the outdated version 5.1.2-9, whereas the current one is 7.0. It seems you tried its non-optimal options (e.g. they don't offer 24 kHz sample rate, but offer a pointless 1 Mbps bitrate), and then decided to puzzle us with the question what to do next. And I've already answered you by listing encoders that work well with low bitrates. Why don't you try them?

Last post by KevinB52379 -Thank you very much.
I'm still not sure why John's builds aren't working right for me though...I find that odd since his binaries are so reliable.
Thanks again!

Last post by shadowking -Which LAME version is recommended? (I didn't like LAME's sound color in my tries. I used Shotcut.)3.100.1 , BTW you add -q6 or -q7 to see if sounds better.

MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by KevinB52379 -As I said the build, I believe it was from March 21, works fine, but everything newer from late March until mid April has these slow down issues, where it encodes slow, and the system hangs.
But if I use Case's build attached to this forum from a few days ago (5.2.2) it works perfectly fine (I know it's a Win32 binary).
If you want me to test something, let me know, I'd be happy to try and troubleshoot for you!
