PiDisk – syncing the music library

More command-line fu, this time mostly on your Mac instead of the Raspberry Pi. The purpose? To create a robust solution for synchronizing your music library (or libraries) on your Mac over to the PiDIsk. John Reekie walks you through it step by step and concludes the series: “All in all, I’m very pleased with this playback ‘ecosystem’… you don’t have to spend much to get started.”

PiDisk – adding the music services

Files are one thing, but music is another. To make the PiDisk music-aware, John Reekie adds two services to it. MinimServer gives UPnP clients a “music aware” view of the files, while BubbleUPnP turns the player into an “OpenHome renderer.” Meaning? TIDAL too.

PiDisk – an inexpensive Raspberry Pi music server

John Reekie continues his journey into the Land of Pi by setting up a second Pi dedicated as a music server. Pi, case, power supply and a portable hard drive. He goes “command line” on this one, but provides step by step instructions all the way. This article, the first in a series of three, provides the foundation by setting up the Pi as a file share.

How to Network your Mac music system with the Raspberry Pi and HiFiBerry – Part 3

John Reekie wraps up his three-part series on an inexpensive music streamer built from a Raspberry Pi and a HifiBerry DIGI+ interface card. This instalment covers a range of topics that didn’t fit in the first two instalments: more controller apps, Wi-Fi, Airplay, use with an Android tablet, and various questions and thoughts about power supplies and DACs. As a bonus, he briefly covers how to use the PiStreamer with JRiver Media Center.

How to Network your Mac music system with the Raspberry Pi and HiFiBerry – Part 2

“Networked music playback can be a bit… confusing,” writes John Reekie as he begins the second article in his series on the “PiStreamer.” He decides to use a simple (ish) architecture with a music server running on a Mac and a controller app running on an iPad, and shows how to set up the various components.

How to Network your Mac music system with the Raspberry Pi and HiFiBerry – Part 1

“In this article, I’m going to take a bit of a right turn…” writes John Reekie, as he prepares to sort out a streaming music solution based on a $35 credit-card sized computer. Add a digital interface board, a case, a power supply, a Wifi card… OK for a bit over a hundred dollars, “there’s no reason every Mac user shouldn’t just get one to play with.”

The Four Ages of a Music Library

“All the world’s a stage,” wrote Shakespeare in the introduction to the monologue on the seven ages of man. Dan Gravell writes about the lifecycle of a computer music library based on his twenty years of experience in managing music libraries. Over the course of the “four ages” of a music library, he covers file formats, tagging, and security.

The Rational Audio System

Richard Thompson proposes that we take a rational approach to high-fidelity sound reproduction: “My argument is that we should simply ditch every arbitrary distortion of the signal if we can” and not continue to “dress up traditional compromises with exotic materials and pointless over-engineering.” He tests the concept with an active system based on low-cost components and linear-phase crossovers implemented in PC software.
