Toot

After 4 years being wireless, I'm going wired again. I dusted off my old AKG K550 headphones and bought a new #DAC. The #HiBy FC4 sounds great with MQA from #Tidal. It also works fine with Linux.

An interesting finding is that #PipeWire resamples everything to 48 kHz by default. If you want higher sample rates, you have to tweak the config.

@sesivany This has tempted me for a while, too.

My Audio-Technica ATH-M50X headphones fell apart and I gave them to my son. They were destroyed soon after. 😭

@major @sesivany I got a new pair some time ago for my desk. They are awesome! 🎧

@sesivany It boggles my mind that we haven't been able to get proper good wireless audio.

@bastilian I've had a Sony WH-1000 XM4 that can go up to 96 kHz using LDAC, but when I compare them side by side, HiBy+AKG is a superior experience, noticeably.

The Sony headphones also have their charms. They support 360 Reality Audio which is an interesting experience. There are not many recordings in this format though.

@sesivany I've got the AiAiAi X10 wireless adapter and headband, which is great, but if I wire them up with the same drivers you can hear that when it's wireless it looses on both ends.

In general for the majority of people current wireless audio is probably good enough, but I think you've already been listening to music with good wired headphones before, even just the Beyerdynamic DT770, it is really hard to except anything else, because it wouldn't sound right.

@sesivany So when I take my 44.1 kHz audio source, remix it in my DAW and then export it as 44.1 kHz audio CD, it gets resampled at least twice (44.1 > 48 > 44.1) when I run it through PipeWire?

@fuxoft @sesivany The DAW should tell you what rate it's working at (Ardour does at least). You can use PW setting 'clock.allowed-rates' to allow other rates than 48K at system level, and PIPEWIRE_QUANTUM env variable to tell individual apps at what rate & buffer size they should run. That at least works when going upwards to 96K. I now tried 44.1K and Ardour still reported 48K, i'm not sure why. I had to set PW setting 'clock.force-rate' and now Ardour reports running at 44.1K.

@jistr @fuxoft@kompost.cz I think there is an API the app can use to negotiate with PW what sample rate to use if you allow more rates. But if the app don't use it, the default one is used.

Interestingly @trilobyte found out that if he runs Audacity on PA backend, it negotiates the sample rate, if he runs it directly on PW, the default one is used. Seems like Audacity supports it for the PA API and hasn't implemented it for the PW API.

@sesivany @jistr Audacious 😉 I love this old school app 😁

@sesivany Let me add that pw-top is a great tool for monitoring what sample frequency is required by which app, and what is used by the sound card in the end.
