I've added some interesting new features to sKit (1.1).
the audio streaming series
I'd like to introduce the first release of soundcheck's tuning kit - pCP (sKit) .
sKit provides a small and potentially growing number of little tools that'll help to setup piCorePlayer 7.0+ and Rpi4 and 3 in line with the advanced tuning recommendations outlined in my Audio Streaming Series.
The underlying idea is to take quite a basic operating system like piCorePlayer and tune it that way that it'll provide you with the best possible performance -- challenging most other (audiophile) OSes and streaming solutions out there.
This is not just another of these meanwhile numerous "audiophile" operating system out there though. In principle these do nothing else then applying this or that tweak you'll also find on this blog for years. The idea is to provide you with a tuning kit instead. You take it and apply it to that standard operating system installation yourself. And sKit supports you on that.
You'll put yourself in the driver seat. And you control the pace.
sKit already goes slightly beyond the earlier outlined Audio Streaming Series scope. You should still go through the Audio Streaming Series step-by-step though. sKit doesn't cover all settings yet. At the relevant spots inside the Audio Streaming Series I refer to sKit.
I hope you'll enjoy the results.
...how they work?
The powering scheme. The handling of it to be exact. I've still been pulling plugs all the time for that very purpose. Pulling plugs in a lab is one thing, doing that in a living room is simply not acceptable on the long run. How do you tell your wife or kids how to turn on that DIY monster-stereo !?!? Push that plug, next this one and finally that one. Simply not possible.
I finally thought to get some Wifi controlled mains plugs in place. Neither Dect, infrared nor bluetooth controlled devices made it on my wishlist.
Let see what IoT (Internet of Things) projects are offering...
Anybody out there still ripping CDs? Or is it just me. ;)
Recently I figured that some tracks were missing. No idea when and why this happened. OK. Quick decision taken. Re-Rip the affected CDs. Yep - I still keep my CDs in the attic.
This article gives some background info and directions related to CD ripping and CD tagging.
Meanwhile this became common knowledge in - let's call it - audiophile minded circles.
As usual, I prefer reasonably (priced) highest performance solutions.
Usually a healthy mix of DIY efforts and commercial stuff gets me there.
by running LogitechMediaServer as server and squeezelite as a client.
This post, from a hardware perspective, pretty much relates to my
RPI I2S HAT DAC projects I've been running over at DIY-Audio.
Some DACs (TI PCM51xx family) have shown a slightly improved performance
while running upsampled material. That's the main reason for writing all this up.
USB-Audio Interfaces are pretty much commodity products nowadays. Usually they are Plug'n Play
Does it make U feel uneasy ( once in a while ) of not being in control of something?
RU the type of person who takes it easy - "What I don't know, I don't care to know..." ?
No !?!? Never heard about them?
...the end of separate DAC + AMP audio systems is near!!! ;)
That's what I thought when first publishing this article in 2012 after playing around with this breed.
I then wrote: "For those of you who got tired to run after every new DAC or Amplifier (I did), and those who've read the 1000th review of another miracle DAC (I did), or those of you who got more confused then enlightened with the endless number of DACs of choice out there (I did again), or those who look for a very small, cost efficient and still great sounding system ...
And now I am realizing after more then 8 years further down the road not much has changed.
After abandoning this FDA project I slipped back into old habits, chasing DACs and amps.
I've been looking at the subject of audio data resampling now and than.
Somehow you can't avoid looking into it - for several reasons.
In my case my HW setup (DAC) suggested to try resampled data to achieve an overall potentially better performance.
While scanning the net I stepped over a lot of very fragmented and also incomplete
Quite some stuff out there has a marketing flavor attached to it. And obviously you'll find numerous different opinions about the best way doing things.
- What is resampling or upsampling/downsampling or oversampling?
- Why resampling?
- Quality factors and quality targets
- What tools and applications ?
- Implementation on LogitechMediaServer
- Offline resampling
Let's get started.
