Nice.

>>61047045
Yes my fav audio codec got updated!
Time to lower my bitrates from 48kbps to 8kbps!
>WTF REALLY?
Yes I stored my music on my phone as 48kbps opus files or even 24kbps.
Sounded great for such a low file size... then my s5 died 5 months later.

I wish my PMP could play Opus. It runs FLAC and Vorbis fine but having all my music crushed into a small microSD satisfied my autism.

>>61047045
time to re-encode everything from 128 to 96 then

>>61047483
Me too Anon!
I love fitting 5 minutes of music in 1024kb of space or even tried fitting 80 minutes of audio in something like 10mb.
That shit is so much better than spinning those pesky autism spinners

>>61047483
what are you using?

Clip Sport
It was an impulse buy from my mother when I said I was interested in getting a PMP
[spoiler]I have two[/spoiler]

>>61047045
that 32 kbps clip is impressive, compared to the mp3 one, very usable

>>61047556
My hobby is trying to fit the most data (i.e., in human terms) in the smallest amount of space I can. Opus is my go-to for audio.
>Audiophiles hate him!

>>61047045
The 32kbit music samples are insane.
I was very impressed it can do this much at 32kbit, and how much each version improved on the former.

When will anime rips start using Opus?

>>61048048
I wrote a script to do images.
If you actually do that, you might want to look into pngquant as well. It does lossy png compression (though it doesn't convert in place, detect if it actually made it smaller, or give any output). It's usually better on larger files.

>>61048150
Nevermind, found it.
>>61048152
I've been re-encoding archived anime with FLAC audio to Opus to save disk space for a while. I wouldn't expect it to happen though. People will probably continue to use more widely compatible formats.

>>61048220
I've had decent luck with zopflipng. My method was to run optipng through a directory and then run my favorite images through zopfli for a few more bits shaved off. Very primative but I was never good with computers.

>>61048292
>Under default settings, the output of Zopfli is typically 3–8% smaller than zlib's maximum compression, but takes around 80 times longer.
>80 times longer.
Dear lord. I'll still check it out though, thanks anon.

>>61048152
Pretty much all anime comes pre-encoded as AAC so there's really no point in re-encoding it. Release groups that re-encode audio to FLAC for blurays are fucking retarded.

Does HE-AAC have better sound quality than Opus 1.1/1.2?

>>61047045
>48kHz

reencoding my music in 48kbps vbr atm
is this the safest choice?

>>61050782
For which kind of use use?

I've used 96 kb/s Vorbis for storing some music on phone. Been very satisfied with that, I've even connected it to a sound system and to my surprise it sounded okay.

I think by using Opus instead of Vorbis you might be able to cut the bitrate maybe 1/4 or 1/3, so I'd try 64 kb/s or something like that.

>>61047045
Whoa, that's amazing. That 32 kbps Opus samples is insane.

>>61050073
Public test shows the superiority of Opus over HE-AAC at 64kbps. Lower bitrate is unclear with not test.

Been testing opus alpha regularly. Big fan of Opus/Vorbis.

New 1.2 is good for low bitrates, such as audio books or TV-shows without music or demanding audio effects

If you have with 96 kbs in previous version, you probably won't notice a difference in an ABX test since the audible improvements are in the low segment. (Vorbis will work just as fine as Opus at those rates or higher.)

Remember that depending on encoder, it may either follow the target bitrate closely or deviate by adding up to 20%.
So one encoder told to do 64 kbit/s but adds a lot, and another that's told to do 80 but makes sure to stay below, should be judged by actual file-size and not your settings.

I didn't really know anything about the technical side of Opus until just now. So Opus is like two codecs combined into one. SILK codec works best on frequencies up to 8kHz and the CELT codec works best on the higher frequencies. You can use one or the other, or combine them and let each codec handle what it does best.

That's really neato.

>>61047357
Replacing existing opus files with new opus files encoded from flac? Sure.

AAC is still better

Making the world a better place.

>>61048048
>jpegoptim
>not mozjpeg

>>61055492
AAC has the better compatibility. Opus is better, though, if your player supports both.

>>61057066
>Opus is better, though
I'd say that's true most of the time, but there are cases where AAC is better. And keep in mind there are different AAC encoders that perform very differently.
Also AAC decodes faster.

>>61057727
AAC-LC is fast. Opus is faster than HE-AAC.

>>61057743
>Opus is faster than HE-AAC.
When decoding? I don't see it.

>>61057821
https://www.rockbox.org/wiki/CodecPerformanceComparison

>>61055492
With Opus I can use one codec and it will adapt depending on what bitrate I want.
With AAC I have to choose the correct one for the job (LC-AAC, HE-AAC, HE-AAC-v2)

In my own subjective tests Opus now beats HE-AAC v2 for really low bitrates (32 kbps). It didn' t use to do that.

Only advantage with AAC is that it's supported by most and resilient to additional loss when recompressing with the same codec and bitrate. I.e. you won't noticeable deteriorate the quality. (Unlike other lossy audio codecs or JPG.)

>>61052160
Actually it does matter when there's a 30 years worth of recording material saved specifically as 44.1 kHz. Conversion to 48kHz isn't lossless

>>61058114
You can use flac for archiving. 16 bit int -> 32 bit float is lossy to begin with.

Love this.

Went autistic and re upped my phone music library using the new opusenc tool and saved tons of space.

What's ur parameters when converting FLAC to Opus?

I use --bitrate 32 or 64 if I have the space, and --comp 10

>>61058114
>Conversion to 48kHz isn't lossless
Good thing we're not doing lossless conversion, then, eh?

>>61048220
Why not step it up to webp?

>>61058154
>--comp 10
Complexity 10 is default. No need to specify.
I prefer HEVC and Opus 48k-64k for Stereo (2-channel) film (down to 32k for documentaries) and 96k for music.
(But usually do Vorbis for music with same bitrate since it's supported by my MP3 player).

>>61058148
Bit depth has no effect on sampling rate. It's a completely different metric.

>>61058338
I thought you were talking about CD source because it's the only format where 44.1kHz matters.

>>61058314
Good to know.

>96k for music

Honestly its hard to tell the difference between 64k and 94k

WIthout looking at filesize or bitrate tell me which track sounds better?

1) https://my.mixtape.moe/ltdlob.opus
2) https://my.mixtape.moe/harfyd.opus

Anyone can join in too, Just dont cheat

>>61058540
>hard to tell the difference between 64k and 94k
Yes I agree in most cases it's very difficult.

When testing codecs, I usually rip something from a good quality CD.
Encode it with various settings, and then decode it back to WAV.
Burn the WAV to CD and play it in the stereo (since it has the best audio).

Tested your sounds with sennheiser attached to the attached to this comp.
(I hate soundblaster btw, but the gold plated connectors and stuff looks cool I guess.)

Can't judge which one is best. They all sound equally good to me.
But I think the original probably isn't the best for critical listening.
At 22 secs in (and around there) it sounds like heavy distortion but I know it's not from the codec so I guess it's the way they want it to sound.
Also has some faint backgrounds sounds that's still audible on both, (no idea how original sounds) so it didn't miss much.

Sorry if I didn't analyze more than 30 secs, but it really isn't my type of music.
Probably good for critical listening if you attuned to it.

>>61058271
I would, but not much supports it. My image viewer doesn't, and I don't think you can post them on 4chan.

>>61047045

>>61058667
It's okay, I only test the first 30 seconds too

The original is here if you really want to compare
https://my.mixtape.moe/zzwsli.flac

In any case I think I will stick to 64k for phone music because it appeals to my compression autism. But really 96k seems to be the best from what Ive read

>>61058812
Why would you convert mp3 to opus?

>>61058827
Someone dropped 320 kbps MP3 torrent with some Discography, and now you want to save space?

>>61058827
old files, newer files are currently in aac

>>61058850
Find flac of the same albums. Unleash your autism and be a man.

>>61058850

Oh for saving space, yeah sure. I'd just keep the MP3 since i dont want to lose quality.

I only encode opus from FLAC or archive formats. If there's an MP3 320 V0 rip then I'll leave it as that.

i've been considering what bitrate to use on my PMP for running and the gym. quality isn't super important when i'm not sitting perfectly still in a quiet room, so music sounding acceptable at 48kbps got me to do some math

Average Album Length = 45m

Average Album Size
>48kbps = 16MB
>64kbps = 22MB
>128kbps = 43MB
>320kbps = 108MB
>900kbps = 303MB

Albums per 64GB
>48kbps = 3949 albums
>64kbps = 2962 albums
>128kbps = 1481 albums
>320kbps = 592 albums
>900kbps = 210 albums

Artists per 64GB, 10 albums per artist
>48kbps = 394 artists
>64kbps = 296 artists
>128kbps = 148 artists
>320kbps = 59 artists
>900kbps = 21 artists

I can't name 400 artists that I enjoy, so 48kbps seems overkill. 64kbps would let me stuff pretty much everything I can think of, and have plenty of room for audiobooks and podcasts.

128kbps would remove any quality concerns in the back of my head, and 150 artists is way more than enough for a gym playlist. Think I'll go with that.

Opus has an adoption problem. There are literally no music stores or streaming services that distribute Opus. Not even Bandcamp sells it and Bandcamp sells music in almost every format, even Apple Lossless which not even iTunes sells.

>>61061919
Why would they when billions devices supporting MP3 and AAC, almost none supporting Opus and the latter has little to no advantages for music on non-autistic bitrates?

>>61058740

>>61058314

I use 192 because it's still smaller than mp3 at max quality and it retains FLAC style quality

Opus would be terrific for streaming services like Spotify (which currently uses Ogg Vorbis). Terrific quality sound at lower bandwidth would significantly reduce costs around the board.

>>61058945
Neutron.

Looks like shit but every other player lacks features compared to it.

>>61047045
See, this is the reason this meme will never get popular. mp3 was the same since... 1997? People dont need change

>>61063012
That's retarded. Throw away your PC and get a typewritter. You don't need technology, and we don't need your bullshit.

>>61063012
MP3 encoders changed a fuck-ton. Decoders don't change but encoders can do whatever the fuck they want as long as they produce a bitstream that is compatible.

>>61063077
Well yeah but it seems to be the change of format. else why call it opus 1.2?

>>61063273
Opus is backwards compatible since version 0.8.
Just stop posting.

>>61063273
The encoder changed, the format remains exactly the same. All that changed is the encoder discards more useless information and retains more useful information but the format it outputs is still compatible with the original specification

>>61047473
How did you do that?

>>61063273
The reference implementation libopus gets updated to 1.2.

He's sorta right, most people watch anime from Crunchyroll rips or TV raws which are hard coded AAC.

>>61066163
He is not right:
>Release groups that re-encode audio to FLAC for blurays are fucking retarded.

>>61066163
I was wrong though, I was referring to blurays. I assumed they used some kind of encoding but I didn't really bother to check.

>>61066163
>Release groups that re-encode audio to FLAC for blurays are fucking retarded.
>Re-encode
He's a retard.
Groups are encoding lossless(LPCM) to lossless(FLAC).
So the statement is wrong.

>>61057066

If you rename .opus files to .ogg files they'll play on basically anything nowadays, even Android has native support for the Opus codec but you have to change the extension because the .opus extension is actually a .ogg container anyway.

Protip: change your *.opus files to *.ogg extension files (on the device) and any audio player can handle them without issues. Not every audio player will "see" .opus extension files but they can all see .ogg and it's the same thing.

The 32 Kbps is pretty impressive with Opus 1.2, been using 128 Kbps with 1.1 for a while now, not like I'm going to re-encode my entire collection (like 13K+ songs) but even it's not bad at all for mobile purposes.

Made some samples, let's see who can pick which is which - same source material (TRON:Legacy Recording Sessions by Daft Punk, CD source to FLAC then to Opus 32, 64, 96, and 128 Kbps) then back to WAV and then FLAC level 8 for testing.

What's the proper order from 32 to 128?

http://www65.zippyshare.com/v/OVGDlqtp/file.html

>>61066922
The extension .opus is a must for a good experience. One of the reasons the vorbis have little popularity is to use the .ogg extension instead of .vorbis.
Google has to add support for .opus.

>>61065778
Default 20ms is optimal.

>>61047045
does it still upsample 44khz to 48khz?

>>61048152
why didn't you download my encodes?

>>61067509

>The extension .opus is a must for a good experience.

That is the most ridiculous thing I've heard today, seriously. The Opus container isn't actually, it's an Ogg container, and *.opus is *.ogg in reality so changing the extension of the files is irrelevant in the big picture.

As I said, you don't necessarily have to alter the extension in your main off-device library, you can simply rename the files on the device to *.ogg and anything including the native audio players in most OEM Android distributions can and will play them because the Opus codec is supported and has been since Android 6 was released.

The extension itself really means Jack Fucking Shit, and the concept of it meaning a 'better experience' is just ludicrous. The container extension only matters because some devices can't even "see" .opus files even in spite of being able to play them without any issues whatsoever.

I mean really, try harder next time will you.

>>61067615
It literally doesn't fucking matter at all you autist.

>>61067509
you just need to use this, it's opus inside with the ogg container, nothing to do with vorbis

According to this graphic, the bigger framesize/delay, the better the quality.
Smaller framesizes are used for streaming purposes, bigger framesizes are used for archival purposes.
If you're going to encode your lossless library in opus, set the framesize to 60(maximum supported by opus).

>>61067810

I use Audio Converter on linux

>>61067667
>>61067810
Fuck nigger. I know it's ogg container, but the correct extension for audio encoded in opus is .opus, always. Stop breaking the experience, the right is right and ready.

Interesting.

Opus at 32kb/s reminds me of a good tape recording.
