RaspyFi (now Volumio) is an open source linux distribution. It will transform your Raspberry Pi into an audiophile source, in 10 minutes without hassles. It comes ready to play, and it’s compatible with almost every USB DAC available. You can consider it as a Voyage-MPD version for Raspberry Pi. But it’s simpler to use and it has several other functionalities! With RaspyFi you’ll be able to play your music library directly from an USB Storage or from your NAS. You can also listen to your favourite web-radios and scrobble your favourite tunes from Spotify, Last.fm and Soundcloud. You will be amazed about the sound quality! RaspyFi’s core feature is this. We are trying to get every bit of your music to play as accurate as can be, optimizing every aspect of the system. RaspyFi supports asynchronous playback to take advantage of the latest DACS, it features a nice webgui you can use to configure it without hassles and to play your library from your pc, your smartphone or your tablet. You can connect your little Raspberry Pi to your Audio System, sit on your couch, use your favourite device (Win,Mac,Android,iOS) as a remote control and enjoy your music as it is. With RaspyFi your Pi never sounded so good! http://www.raspyfi.com/

Contesto
● Crescente interesse per la musica liquida
● Assenza di soluzioni commerciali convincenti
● Rivoluzione Embedded ( Raspberry PI)
Rivoluzione Embedded: Raspberry PI
● Dispositivo (quasi) totipotente
● 35 $
● 1,2 milioni di esemplari (ad aprile 2013)
● Community enorme e proattiva
Rivoluzione Embedded: Raspberry PI
● Fanless
● Bassi consumi
● Connettività USB e Ethernet
● Bus I2s
● Potenza di Calcolo sufficiente
Hi-FI PI
Antecedenti
● Voyage-MPD (debian based)
● Foobar (Windows)
● CMP2 (Windows e Hardware dedicato)
● Audirvana (Windows e Mac OS X)
Concept
● Qualità innanzitutto● Semplicità di installazione e utilizzo● Lettore Universale ● Approccio UI naturale● Integrazione con dispositivi esistenti (NAS, Router, DAC)
● Personalizzazione in base al contesto
Ricetta
● OS Minimale (multistrap, debian armhf)● Alsa ● Kernel ottimizzato● MPD e MPC(17.4)● Web Ui (Nginx, php5-cli)● Minidlna e Avahi (Discovery, possibile per
render)● Shairport (Airplay)● LCDProc e WiringPI ● AutoFS
Risultato
● MP3, FLAC, WAV, AAC ALAC e WebRadio● Bit Perfect● Airport, Samba, DLNA, (Spotify)● Ramplay
● WebUi per controllo riproduzione e configurazione
NESSUNA CONFIGURAZIONE RICHIESTA: PRONTO A SUONARE
