|An example - Instrumental groups
from the 1950/60s. "The Fentones" The group made several 45
singles but they are difficult
to find. Some are now available on CD, but if you have the original 45
record - Answer - have the ability to
restore it. Another
interesting area is the restoration of 78 rpm disks, assuming you
have a player. I believe this is
an area which can be
ligitmately approached by the restorer.
There are many records which are available cheap from charity shops in the UK and with a little work can be returned to a qualititative specification. Mel Blanc singing "I'm glad to be Bugs Bunny", This one in my view is worth the effort as the end product can give tremendous pleasure to those who remember the man and great fun to a generation who don't yet know of his skill. See the Sample Sounds folder.
|So far I have
some experience (17 years) in digitising and converting analogue sound to
most audio formats. Restoring demonstration discs from the

Reel (3 ¾, 7½, 15
Once digitised and restored conversion to different audio formats can be useful, depending on how you intend to play back your restored file. However, for the serious archivist reduction to mp3 seems to me useful and has be come the default. Items such as home concerts, school plays which are often lengthy are best stored in an encrypted manner. Mp3 is powerful encryption tool for just this purpose.
|Some Hints / Tips for
the would be sound archivist
You will need some form of audio editing program
If you don't want to get
mortgage for the
program. Consider the following:
DART pro, (30 day evaluation)
A free full
featured audio/midi studio for the PC. See Sample Sounds
An alternative metadata container
The Radio Industry Standard (RIFF).
But be warned not all users can read it.
Graphic/display file use, under the Windows system, it is possible to place a graphic file in the folder containing your mp3 files to display. Using Windows Media Player all that is required is a suitable size (500 x 500 pixels avg.) and the file renamed to "folder", e.g. folder.jpg.
Set WMP to Album Art. It is also possible to embed the graphic file into each mp3 file. Tho this can be time consuming.
|You can not make a silk purse out of
a sows ear.
The better the quality you can start with the less you will have to do
to restore it to achieve reasonable sound quality.
The aim of the restorer is to reproduce the original with fidelity, not add to it. (It will take time there are no short cuts!)
When digitising an analogue source start with the highest possible sound quality e.g. a 78 record may be very scratchy and sound awfully low fidelity. But it is easier to reduce the band width later than to attempt to raise it.
Where possible create a stereo image (same data on both tracks) for compatibility (for use on modern equipment.)
*In some cases it is possible to improve mono records to stereo, however, be careful, it does not always work well; be selective.
Mp3 comes into its own
100Mb file will often only take up 10Mb.
A 2 min file (40Mb wav) may only take up 2Mb at a suitable compression rate.
128 kbps (Internet usage),
160Kbps (Near CD quality),
192Kbps (CD quailty),
256Kbps (slight over kill)
320Kbps (definate over kill)
Avoid VBR (Variable Bit Rate) unless you have good reason for wanting a small file.
Remember to insert your ID3 tags - so much more fun!
|Most modern sound cards will digitise
44 or 48 kilocycles ("Hertz"
if it you prefer)
at 16/32 bits.
If you are lucky enough to own a Mac digitise your sound files to AIFF.
If you have a PC limited to WAV format, find a codec. AIFF still has an edge, in my opinon.
|Mp3 = MPEG-1 Audio Layer 3 (Moving Picture Experts Group)||Kbps
= Kilobits per second
