Which Bluetooth SoC will be in the TT13 and what sample rate will you preconfigure it to? What type of cartridge and stylus will it come with? Will these be changeable/upgradable?

I've never pursued low latency myself. Just been pursuing high quality audio without giving latency a second thought. So, I'm not sure I can help. You tried aptX Adaptive in LL/gaming mode and it sounded bad too? You might need to wait and see what XPAN brings to the table. There seems to be...

In a follow-up to the above... I just spent a week trying to find a way to confirm I was getting aptX Lossless. Turns out you literally need Qualcomm’s diagnostic software (QXDM) or to capture the packets arriving at the receiver and confirm they contain lossless data. I mentioned the Android...

I assume so. It's in the Qualcomm aptX User Guide for developers. It implies they have a hardwired requirement for 2.4GHz Wi-Fi to be off. It is written about smartphones though. So, I don't really know how much it would apply to a PC. It's all about achieving "QHS" (Qualcomm High Speed) which...

Technically yes, whatever Windows is set to, that’s what it’s going to pass to the USB regardless of the audio source files. This is where Apple mobile devices are better because they automatically adjust to the source audio. Android with UAPP can do this too. This can be seen with DAC’s that...

So there’s no such thing as an aptX Lossless codec in reality. It’s R2.2 of aptX Adaptive. It’ll only do lossless if it’s fed 16-bit and the environmental conditions are ripe for an excellent signal strength. I don’t think Windows will be feeding the dongle a 16-bit source with that Sound...

I wonder how they’re doing that. According to the developer documentation, they would literally have to capture the packets being transmitted to see if they were the lossless ones. Although I did spot a couple of log entries which only seemed to be associated with what was going on at the times...

It’s the combination of their smartphone (aptX Lossless annd LDAC) and the newly shipping “LHDC ONE” dongle.

The screenshot of the "Qualcomm aptX User guide" you showed, I have this whole document and it is clear that it has both "lossless mode" and "HQ mode", where HQ mode is the lossy mode. The phrase "scale-to-lossless" refers to the BT bit rate not to resampling sources. It must be "fed" 16/44.1 or...

You're trying to pass this off as Qualcomm but it's not what Qualcomm said in 2021 and the developer content watermark isn't showing here. It is insane to think that they would convert all 24/44.1, 24/48, 24/96 content to 16-bit 44.1 and transmit losslessly. Qualcomm told the hardware...

What you've screenshotted here, supports what I said. There is no evidence in this screenshot that they are downsampling 24-bit or Hi-Res. There would be no point in having or discussing references to 24/96 in the specs. :laughing: Audiophiles would have their guts for garters. It is totally...

Not true. Qualcomm informs developers that only content that is already 16/44.1 is supported for aptX Lossless (over Classic BT). They don’t do any transcoding for aptX Lossless. There is no time, nor is there energy allotted for that. The chips are powerful for their size but they’re not that...

Lossless is 16-bit only. So, with 24-bit showing, it gives you cause to doubt things but I don’t think this app is a good enough gauge at this time. It doesn’t always change what it’s showing when you change content. I’m not sure it’s well tuned for the latest smartphones and codec...

That’s not a way to check it’s lossless. The sample rate is not enough to confirm it’s lossless. You also need to know that it’s 16-bit. The source has to be 16-bit/44.1 and reach the BT chip unaltered; which itself can be a challenge. Then it’s just automatic with no current way for consumers...

“aptX Lossless” isn’t a BT codec in its own right. It’s largely a branding of the 1.2Mbps mode of aptX Adaptive R3/R4. So, it doesn't appear in the Developer Options (at this time anyway in Android 14). It's also a file format designed to compete with ALAC.

My ”D&o.sky81” QCC3081 ear hooks arrived today. The only lossless ear hooks out there. No major complaints. Trigger the Snapdragon Sound logo when connected to my ROG Phone 8. Sound and comfort were great. They charge individually and directly via USB-C and come with a charging cable that...

It’s just become tradition to shorten x86_64 to x86 when talking about the CPU’s that use that instruction set. It no longer infers any relation to 32-bit.

Where did you hear this? It is contradicted at 25m 23s by

This is just the bitrate that is needed locally/internally within the playback device for zero latency. It’s not something you’d really consider in terms of Bluetooth transmission rate. Bluetooth devices can also be using memory buffers in lieu of or in combination with compression but this...

In my humble opinion it’s definitely better. I hear AAC as somewhat muffled in comparison. The issue I see with it though is that it is likely to be a big battery drain and the dongle will get very hot. I think this is why we haven’t seen an LDAC dongle before now. So, it will be interesting to...

At least iPhone users have a USB-C LDAC dongle on the way from FiiO. Shame the BT11 is not also offering aptX Lossless.

As I understand it, but it can be hard to find the proof, aptX Lossless over LE Audio only does 16-bit. Not 24-bit. There is not enough bandwidth for 24-bit 48kHz in Bluetooth. It was always going to require Wi-Fi. I have seen at least one Qualcomm rep get this wrong around the most recent...

They’re saying BT11 is LDAC only.

I forgot it’s just a BT receiver. I really want a USB aptX Lossless transmitter that’s small.

I mentioned this on their Facebook post by virtue of referencing the S7 Pro platform but I think given they're just delivering aptX Lossless this Autumn, it's unlikely to happen in 2024. I think we just have to live with these platforms taking a few years to proliferate. No doubt the initial...
