What are the overall best lossy audio codecs for music and video?

>AAC
>AAC-LC
>HE-AAC
>AC3
>E-AC3
>FLAC
>MP3
>OPUS
>xHE-AAC

>>105904655 (OP)
opus
>ib4 sauce
made it up

>>105904655 (OP)
FLAC except it's not lossy

>>105904655 (OP)
>lossy codec

aac
transparent at high enough bitrates and has better hardware compatibility than opus

>>105904655 (OP)
>FLAC
>lossy

>>105904655 (OP)
>best lossy audio
mdr has we say in France

>>105904718
>AAC
>AAC-LC
>HE-AAC

What's the difference

>>105904825
just use aac-lc
he-aac is for low bitrates

>>105904655 (OP)
Opus, it's not even a competition. More like a straight up slaughter. The ONLY thing that can compete with Opus is either AAC HE and XE but both of these are royalty infested cancerous tumors.

MP3 will always BTFO AAC/OPUS/everything else if hardware compatibility is a concern DOE.

>>105904718
is there any info on opus being more transparent than aac at high bitrates?

>>105904852
Depends on the variant, the LC one is DOOGSHIT compared to Opus and LC has like 70% as good hardware compatability as MP3. HE and XE do much better but again they're royalty infested cancerous tumors unlike Opus.

As long as you have like at least cortex A55 on your phone you should only have like 10% worse battery life using Opus vs say AAC-LC.

>>105904936
thanks, i like to believe opus is just as solid and reliable as flac, since theyre cousins. opus on linux makes more sense too, fuck these royalties.

btw here's what a quick google search returned for cortex efficiency cores. Your phone has to be like 10 years old at this point to not benefit much from Opus.

ARM Cortex-A53– 2016

ARM Cortex-A55– 2018

ARM Cortex-A510– 2022 (part of ARMv9 architecture, designed as an efficiency core)

Its 2025, there is no excuse for lossy audio compression to exist anymore.
I will grant the its not yet practical to dispense with lossy video compression, but anyone using lossy audio should be put to death.

It all doesn't matter since your ears are getting old.

>>105905122
This only really applies to MP3 which clips the high frequency ceiling at 18 Khz. Opus even at low bitrates like 64kbps leaves it alone at 22 Khz.

>>105905217
You can still be subconsciously influenced by sounds you can't hear but that ceiling is like 20khz for most humans so Opus is fine even for like 50% of audiofools who admit to there being biological limits to human hearing.

>>105905269
>22 Khs
20Khs*

>>105904655 (OP)
let me guess

>>105905122
HOWEVERTHOUGHBRIT'SM'VE there is a legit use of FLAC but it's quite embarrassing: you purchased a phone without a 3.5mm headphone jack. Since bluetooth SBC will rape your audio you may as well start with the original lossless before it gets raped.

>>105905269
The frequency ceiling is the least offensive part of lossy audio. Lossy audio mutilates the entire frequency spectrum. The mere presence of the entire frequency range is not the same as those frequencies being correct.

>>105905316
dayum, russian girls look like this?

Honestly, if you don't know what you're doing, don't give a shit etc. etc. just use AAC at a bitrate of at least 80kbits per channel. 192kbps AAC encoded with a good encoder is fine for 99.9999997% of material.

for me its opus

>>105904936
you clearly have no fucking idea of what you are talking about
he is specifically asking about HIGH bitrates, and you suggest... he-aac for that?
he-aac literally DECREASES quality at higher bitrates, most he-aac/he-aacv2 encoders don't even allow you to do it because it's stupid, only xhe-aac also works for higher bitrates
and besides, lc isn't dogshit at all for high bitrate transparency, it's basically tied with opus (as long as you use a good encoder such as qaac or fdk_aac)
>has like 70% as good hardware compatability as MP3
also wrong, more like 95% as good hardware compatibility.

>>105904936
>As long as you have like at least cortex A55 on your phone you should only have like 10% worse battery life using Opus vs say AAC-LC.
I sent my previous post before even reading this other bullshit
audio decoding isn't making anywhere near that much of a dent in power consumption, especially in this case because... opus is literally just as complex as aac-lc

>>105905049
dude seriously, what the fuck are you even talking about
Opus works wonderfully even on mp3 players from the ninties with rockbox, a cortex a53 is probably decoding a 4 minute song in less than 40 milliseconds of cpu time, the amount of time spent reading an higher bitrate song from storage probably outweighs the amount of cpu power used
I dare you to show us some data that backs up your claims that "you need at least a phone with a cortex a53 to not lose 10% battery life from using opus", spoiler: you can't, this is some insanely stupid schizo shit

>>105908068
>>105908089
very interesting. thanks.

>>105908089
>>105908117
Probably anecdotal but I have an old celeron laptop that lasts 10+ hours when listening to 320k CBR lame MP3s compared to 8 or 9 hours when listening to 192k VBR Opus so I dunno, I'll just stick to MP3 for now I guess

>>105908333
there's a flaw in your methodology somewhere, a whole ass laptop and the biggest impact to power consumption is some 0.1% cpu use audio decoding? impossible.
but sure I'll share my anectodal experience too:
I left a couple of identical xperia m2 (2014 phone, 2300mAh battery powering a snapdragon 200), flashed to the same custom rom nandroid image, one playing opus and the other aac-lc WITH THE SCREEN OFF.
48 hours later, the phone playing aac-lc drained to 28% while the phone playing opus drained to 27%
margin of error, definitely not a "10% battery life difference".
