Using a Mac Computer as a music server
For use in a high end audio system, obviously along with ease of use
and reliability, the goal of a music
server is to obtain the best sound quality possible. For a music server
there are a number of choices including: a dedicated music server, a
Windows-based music server, a Mac-based music server, or a Linux-based
music server.
With regard to a Mac-based music server you can use an older Mac G5
with a Lynx AES-16 PCI digital audio output card or a current Intel-based Mac running OSX
using a PCI-e card. Of course most people today would prefer to use a
current Mac w/OSX.
One configuration which has been popular is
that you can use an OSX Mac with music server software such as
Amarra or
Pure Music along
with a
Lynx
AES16 PCI-e card and play AIFF or WAV or other file types that
either come from your CD collection or are downloaded.
However, if properly implemented, the best way to use a Mac as a
music server is to use the USB output. You can use a Mac laptop, an
iMac, a Mac Mini, or a Mac Pro tower. In our demo system we have been
using a
Mac mini running Pure Music here in the
store for demo along with the new
Berkeley Alpha USB. One possible advantage to the Mac Mini is no video
screen attached which may cut down on internal EMI, etc.
In any case, regardless of which Mac is chosen, you can use the USB
output into an outboard USB-to-AES/EBU converter/reclocker which will
then feed the AES/EBU (or SP-DIF) digital input of an high quality
outboard DAC. The best way to do this is to use the
Berkeley Alpha USB. The Berkeley
Alpha USB is an outboard USB to AES-EBU converter with high quality reclocking and, unlike an
internal audio card, as an outboard component it also further isolates
the computer from your music system.
Note that most high
resolution files that are downloaded are
FLAC files. So either you need
music playing software that can handle FLAC files or you need to convert
them to AIFF or WAV or Apple Lossless.
There are a number of different music server software choices for Mac OSX that
according to their websites will play FLAC and other music file types natively
including:
If you listen to popular music such as rock, pop, jazz, etc. then the
iTunes-style user interface used for some music playing software should be
sufficient—as most people are really only interested in the basic four
metadata fields:
- Artist
- Album
- Track Number
- Track/Song name
However for classical music not only do you want the basic fields
listed above but you also would like the music playing software to
provide additional metadata fields such as:
- Composer
- Soloist (such as the pianist for a piano concerto)
- Conductor
- Orchestra
- Composition Type (i.e. Symphony, String Quartet, Piano, etc.)
- Recording Date
- Remastering Date
- Release Date
The other thing that is quite important is to use high quality audio
files. For a Mac we recommend uncompressed files in the AIFF format.
Here is a
link for more info.
If you are going to be ripping your CD collection we would advise you
to use software that can verify a bit-for-bit copy. Two Mac programs are
XLD (X Lossless Decoder) or Rip.
For XLD here are some settings that you need to know about:
Alternatively if you have Windows in Boot Camp you can use either
Exact Audio Copy or
dBpoweramp.
For a tagging program you can use
Tag.
For metadata there are a number of online metadata databases such as:
- AMG
- GD3
- SonataDB
- MusicBrainz
- freedb
More information about
transferring your CD's to a music server is
here. If you wish to download high quality music files here is
an educational link.
Of course we believe that software and music server hardware will continue to
evolve. However regardless of what music server you use, it is of the
utmost importance that you employ an outboard DAC in order to get high
end audio sound quality.
The digital-to-analog converter that has become our bestselling DAC
is the Berkeley Audio Design
Alpha DAC. You're welcome to stop by and hear both some CD
resolution and some high resolution files played through it. Then you'll
understand how good CD files can sound on a music server as well as why
high resolution files played through a quality outboard DAC are so
great! Note: If you would like to have a Mac Mini setup as a turn-key
music server here is some info
on how to obtain one.
Note: If you are using iTunes and are downloading high quality FLAC files on a
OSX Mac,
you can use MAX software or
Fluke
software to convert
the files from FLAC to AIFF or WAV or to Apple lossless. (This is also useful if you have an iPod and
want to play the same files on it.) |
