Are streaming services evil? For some. For others, they are the gateway to new artists, concerts, and record purchases. Audiophiles that have made the leap are in this latter camp. There’s more to life than the next Beatles reissue. Read on to learn how Roon, Qobuz, and Tidal combine synergisticly to promote artists and music. Roon 1.6 Radio is the secret.

Allo Digione gets a Face
John Darko of Darko.Audio fame asked what you hide your Raspberry Pi based audio player behind. That got me thinking. Give it a face like a Bryston Audio BDP-Pi player. Could that be done?
John was a fan of the RoPieee Linux plus Roon Bridge distribution so I gave RoPieee a try. In reading the RoPieee installation notes, I noticed that it supported the Raspberry Pi 7 inch touchscreen display. Having one lying around, I decided to add it to the basic Signature One player.
As always with DIY, some assembly is required and it is not all in the fine manual. I was using my display with an Allo DigiOne Signature HAT assembly. This HAT blocks access to the GPIO power pins. Oops — what’s the work around. Keep reading after the break.

Radio, like most else, has gone digital. In the early days of digital signal processing, pioneers realized that many modulation and demodulation techniques could be performed by digital computation.
As computers became cheaper and faster and integrated circuits became cheaper and faster, it was inevitable that the guts of radio receivers and transmitters would be mostly digital and that computers would do much of what went on inside new radios.
This post will describe the initial exploration of GQRX and RTL-SDR here at Dismal Manor. Most of what is already written on the Internet neglects to mention a couple of details the Moocher learned the hard way. Find out what these are after the break.

Personal Audio on the Cheap
Much written about personal audio is written to separate the established audiophile from a few dollars to buy a new gadget. This article is written for a student using Spotify or iTunes with headphones on an existing laptop.How can you begin a personal audio system and what are your migration paths going forward.
Continue reading Personal Audio on the CheapWhy Digital Audio Systems Upsample
Digital audio systems since the beginning have used elevated sampling rates for processing while down-sampling the product to 44.1 or 48 KHz sampling rates for storage and transmission. These design decisions are attempts to satisfy the requirements of the sampling theorem using easily implemented anti-aliasing filters and reconstruction filters.
Roon in a BHYVE
FreeNAS 11.2 has been out for a few weeks. After some time running Roon on a Ubuntu equipped 2009 Mac Mini, I decided I’d give Roon a try in a BHYVE VM on the new FreeNAS build. This note recounts the experience so far. As usual, both FreeNAS and Roon have their secrets and they interact.

Gumby is a good gumby
I’ll try to avoid the schiit puns as Gungnir Multibit (Gumby) arrived and is settled in my audio rack. Gumby is a good Gumby! Jason Stoddard and Mike Moffat founded Schiit about a decade ago to scratch their audio design itch. Schiit has an unusual philosophy and take on high fidelity audio equipment, that it exists to serve the love of music and not to be techno-sculpture in the lounges of the rich. Rather than making a big statement piece for the wealthy, they began by making affordable $100 devices for those wishing for more than headphones plugged into an iBook. And they set out to show that you could build here of mostly US made stuff and be profitable.

Home Networks for Streaming Audio
I’ve not written on audio and networking in a while but over the holiday I read Jason Stoddard’s Schiit Happens about his return to the high fidelity equipment industry as co-founder of Schiit, a maker of personal audio and value oriented high end audio. I found the book after I had ordered my Schiit Gungnir Multi-bit DAC. Over the break I had also watched a video in which Mike and Jason (the founders) talked about how Schiit came to be and this, that, and the other thing. They are toying with the notion of offering a new product which Mike kept calling Schiit Pi. This got me thinking I should write about my streaming environment again as I had improved it significantly in 2018.

About a year ago I installed Roon Audio and began using it without Tidal. In my original configuration, Roon Audio ran in a VM hosted by my FreeNAS storage server. It delivered audio to either an Apple TV or a Google Chromecast Audio. Both were connected to a Cambridge DACmagic converter by TOSlink. For the first year I passed on the Tidal subscription, assuming that it, like Apple and Amazon streaming, sounded horrid. Then I got curious.

The Moocher is a music collector with a growing CD and record collection. In this article, the moocher describes how he transfers CD to FLAC to play using Roon Labs Roon Player. We’ll look at the motivation behind FLAC, the tools used to turn a CD into FLAC encoded tracks, and how to get the tools.
