Just a question, will codecs affect uncompressed high quality audio from apps such as Tidal? I'm looking at buying the Bose QC earbuds but they only have AAC and SBC.

@@alexanderbuys2051 If the bose only have AAC and SBC, they won't be uncompressed no matter what the source is.

LDAC

That's exactly what you are, if you needed any validation

Same here, quite.

The biggest learn for me was just how unpredictable latency is and just how fast and loose some manufacturers play with standards, *almost* makes the codec equation a non issue. You can't just look at the spec and go 'ok that'll perform like whatever'. Ultimately it goes back to having to listen, test and try for yourself which is good cos it keeps us reviewers in business :D

on high end audio you should use ldac codec but use a regulated power transformer for your device . its very important.you will be amazed at the sound quality....

FWIW I have a BTR3 and LHDC although supported on both ends is unusable with my Xiaomi K30. On default settings it is quiet and more crackle than music, it can sometimes be hard to even decipher speech never mind listen to music. If I manually (in Developer options) set the sampling rate down to 44.1 or 48 it becomes listenable in the sense I can hear what is going on, there is still I think some background crackle. It's that digital crackle that you get if a cable is too long/dropping out or a CPU is taxed and dropping samples. There's also sometimes a bit of slowing sort of effect, as if it's trying to catch up. I can't overemphasise how bad the sound is, to be honest I find it hard to distinguish between even SBC and higher codecs normally, but LHDC on my phone is utterly unlistenable. Note this is even with Hi-Res source, (Tidal) anything above 48 simply is impossible. For me, it's the sample rate change that (half) fixes it, the other settings (including the 400/560/900 kbit setting) don't seem to have any effect. Now this could well be my phone rather than the BTR3, and I suspect it is the source device. But it's unusable. LDAC by contrast is absolutely fine. All other codecs (AptX, AptX HD, AAC) are also fine. You MAY have more luck if you have a Huawei phone. But do a Google a search for "Huawei LHDC crackling", A LOT of people with Huawei phones seem to have this exact issue I have with LHDC on my Xiaomi. Again- I cannot over-state how bad this is, it's not a minor thing at all. The FiiO is fantastic as a device otherwise, as I say it may be my phone rather than the FiiO. But I wouldn't be enthusiastic about LHDC from my experience with it. LDAC is perfect.

Shawn Orjiakor how do you know if your phones supports aptx HD or LDAC?

@@agoogleuser9025 Go to developer's options and see Bluetooth codecs.

@@agoogleuser9025 And your phone has at least Android 8.0 to have all those codecs.

@@agoogleuser9025 And lastly. Try out Bluetooth products that has Apt-X HD like headphones and receivers. Only Sony products can use LDAC fully.

@@shawnorjiakor Not sure if this is currently true anymore I heard LDAC is now part of "android open source project" so things might/may already have changed regarding that

The low latency codecs used for Bluetooth audio require a slightly higher bit rate for the same sound quality, so it might make a difference if you have MP3 or AAC source material at 320kbps. If you have 128kbps MP3s, then it probably matters less. Even Apple's AAC implementation for Bluetooth will give a lower quality result at the same bandwidth as the original AAC file, because the latency and battery life of the earphones have to be considered when encoding the audio.

Interesting.

The default would naturally be something supported by the audio hardware. Opus should still be a standardized option, since it uses a tiny amount of CPU even on a phone.

Depends on device, as he stated, if you have Galaxy Buds with an iPhone (newest models each) you will go with SBC or AAC, on an Android device (latest model from non Samsung brands) you’ll use SBC with the Buds

Do you you know of a pirate that lives in the bay?

MQA is controversial because it was initially marketed as 'lossless' when in fact it is not. Some people think its great because its a good lossy format and its used in hi-res streaming services like Tidal. But the vast majority of people can't tell the difference between that and Spotify anyway. I don't really have any feelings about it either way, its just another format.

@@WheezyTechThankyiu lots Bro...clean reviews .subs dd

I think the codec choice is mostly moot when it comes to latency, even if one codec is in theory better than another it is too variable in the real world to really say one is better than the other. Its really down to the device. The QCY T5 iems for example only support AAC and SBC but have a 'gaming mode' which is supposed to reduce latency which it must do with one of those two codecs but they don't explain how they reduce the latency so not sure what tricks they are doing to bring the latency down.

@@WheezyTechok thank you. It's heavily device dependent and also environmental factors

I use aptx or aptx HD. I haven't noticed any audio delays when playing rhythm games anymore. I can finally enjoy games and videos with bluetooth headphones.

what does that even mean?😂🥴

@@Blackfeet That's the new AptX standard used in BT5.2. It's a mess - and that's why I won't be switching from cable that soon!

@@maxheadrom3088 Oh. I'm with you on that.😂 I'm currently searching for some Audio Technica open back 1000X's but they're sold out everywhere. Nothing beats cables for lossless hi-fi quality.

Might be flac, since the MP3 is lossy codec and flac is loseless. If you select MP3, the source is lossy-coded twice (MP3 and then SBC). But I don't think the difference is critical, since the loss in MP3 encoding is not so much significant as that of SBC.

Ldac

LDAC, then aptX, then AAC, then SDB

@@OMCPero the last 2 ones are not true its SBC then AAC. AAC is literally the less powerful and worse codec

@@resinds.p4898 You are correct, my mistake

@@OMCPero well i could be wrong too

@@resinds.p4898 yeah AAC only works perfectly with iPhones in Android it works like Garbage I'm telling you this because I have one😭

I did put info cards in what else did you want?

11 now 🤥

@@cartergaming1323 why has it to be apple? It’s proven by expert engineers that aac trough apple devices is the highest quality out there out of lossy formats. There’s no audible difference between streaming a 16bit 44.1 kHz flac. Same goes for measurable difference. Also headroom isn’t gonna be audible by your average audio equipment. And by the way codecs mean nothing when the original recording quality is bad or not optimal. Also makes a huge difference on what kind of recording method was used. Go search and buy dr. Cheky ultimate headphone cd. It’s also available on amazon unlimited in flac 16/44.1. Dunno about other streaming platforms. Has to do with hardware quality and amount of power ( battery and processing ) involved in the processing whereas on android you rarely get that high quality hardware and software management. Practically aptx hd and adaptive won’t sound better than aac. Just so some research. Has nothing to do with apple or android. It’s just a proven fact by many engineers. So to wrap it up, as long as you don’t have high end equipment like high end headphones, there’s no use breaking your head ( like I did for months ) researching. If your equipment or headphones are just average, go either with aptx hd/adaptive or aac. You won’t notice a difference. It’s even hard to notice in higher end equipment if you don’t have a fine/Audiophile ear.

It’s like a having a 1000ps car with too small wheels and tires. You will never get that 1000ps out of it. Same analogy gets for headphones and Bluetooth Streaming. Same goes for Bluetooth 5.0/5.1.the only difference is in a Bluetooth transmission method that’s not even used for transmission of studio. Bluetooth 4.2 it’s just as Good whereas 5.1 only got improvement in things that are not used by audio Over Bluetooth. One tip, if you want a good phone for streaming aptx adaptive, go for Nokia 5.4. thank me later.

change your "hand terminal"

What are you using, because it's possible that your headphones/Audio receiver may not support alternate Bluetooth codecs?
