Audio Recording Through the Ages – Oxford Duplication Centre

Audio Recording Through the Ages – Oxford Duplication Centre The late 19 th and 20 th centuries brought with them a huge range of exciting technological developments, including everything from the advent of electrification to railways, telecommunications and engines.  However, an often overlooked breakthrough was the development of audio recording technology – before 1877, there was no way to record and play back sound and music. It’s mindblowing to consider this, especially as today we can digitally encode audio and store thousands of songs on a smartphone! So how did we get to this stage? The 20 th century brought rapid developments to the world of audio, with new technologies transforming formats and production methods every few decades. For example, the earliest technology that could reproduce sound – Thomas Edison’s phonograph – used wax cylinders to store the resulting audio, but the end result was often low quality and with poor fidelity. The reco

PHOTOGRAPHIC GLASS PLATE NEGATIVE AND POSITIVE SCANNING SERVICES FOR CORPORATE AND CONSUMER CLIENTS IN OXFORDSHIRE UK

PHOTOGRAPHIC GLASS PLATE NEGATIVE AND POSITIVE SCANNING SERVICES FOR CORPORATE AND CONSUMER CLIENTS IN OXFORDSHIRE UK Oxford Duplication have established a preservation technique perfect for preserving photographic plates and prevent their valuable historical information from being lost. The emulsion on the plate can deteriorate. In addition, the glass plate medium is fragile and prone to cracking if not stored correctly. History of Photography, Glass Plate and Tintype Ferrotype Negatives There are 2 types of glass plate negatives and 1 type of tintype negative. Collodion Wet Plate and Gelatine Dry Plate and further below more information about Ferrotypes also known as Tintypes.  Collodion Wet Plate Negatives - 1851 until the 1880s. Invented by Frederick Scoff Archer an English sculptor. Frederick used a viscous solution of collodion coated glass with light-sensitive silver salts. Glass plates created a sharper stable and detailed negative than paper. This was mo

EVER HEARD OF AUDIO WIRE RECORDING?

Oxford Duplication Centre Audio Recording to CD, WAV, AIFF, MP3 SO WHAT IS WIRE RECORDING? Wire recording or magnetic wire recording was the first early magnetic recording technology. An analog type of audio storage in which a magnetic recording was made on a thin steel wire. The first crude recorder was invented in 1898 by Danish inventor  Valdemar Poulsen.   With the first magnetic audio recorder to be made commercially available anywhere was The Telegraphone, which was manufactured by the American Telegraphone Company in Springfield Massachusetts. HOW DOES IT WORK? The wire is pulled rapidly across a recording head which magnetises each point along the wire in accordance with the intensity and polarity of the electrical audio signal being supplied to the recording head at that instant.   By later drawing the wire across the same or similar head whilst the head is not being supplied with an electrical signal, the varying magnetic field induces a varying ele

Understanding file sizes (Bytes, KB, MB, GB, TB)

Understanding file sizes (Bytes, KB, MB, GB, TB) A byte is a sequence of 8 bits. A single letter or character would use one byte of memory (8 bits), two characters would use two bytes (16 bits). Put another way, a bit is either an 'on' or an 'off' which is processed by a computer processor, we represent 'on' as '1' and 'off' as '0'. 8 bits are known as a byte, and it is bytes which are used to pass our information in it's basic form - characters. An alphanumeric character (e.g. a letter or number such as 'A', 'B' or '7') is stored as 1 byte. For example, to store the letter 'R' uses 1 byte, which is stored by the computer as 8 bits, '01010010'. A document containing 100 characters would use 100 bytes (800 bits) - assuming the file didn't have any overhead (additional data about the file which forms part of the file).  Note, many non-alphanumeric characters such as symbols and fo

Comparision between 10-bit Uncompressed and FFV1 Video Archive Preservation at Oxford Duplication Centre

DISCUSSING FFV1 The most common challenge in digitising moving image is the file sizes that result from the actual digitisation.  The file sizes can be huge and with that comes the increased cost of storage and maintenance for long term preservation. Common consensus consider 10-bit uncompressed to be the preservation standard for moving image because it uses no file compression.  It is considered the most reliable safest format for moving image preservation at the current time. 10-bit uncompressed deliver high image resolution, colour quality and sharpness whilst avoiding motion compensation and compression artefacts. THE DOWNSIDE TO 10-BIT UNCOMPRESSED 1 hour of 10-bit uncompressed video can produce a 100gb file. To put it into perspective it would take 21 DVDs to store a video of this size.  As you can see, its a lot of data! WHAT IS FFV1? FFV1 (Full name:  FFmpeg Video Codec 1 ) Contained by ‎: ‎ AVI ‎, ‎ MKV ‎, ‎ MOV ‎ Latest release ‎: ‎Version

DO NOT THROW AWAY YOUR VHS TAPES! Valuable VHS Tapes

DO NOT THROW AWAY YOUR VHS TAPES UNTIL YOU HAVE READ THIS! Oxford Duplication Centre 29 Banbury Road Kidlington OX5 1AQ Tel: 01865 457000 Email: cheryl@oxfordduplicationcentre.com Cast your mind back to the dozens of VHS tapes lying in a box in your attic ranging from Disney classics to The Lion King. While those are not valuable, there are numerous VHS video tapes in existence that are worth quite a lot of money. LIMITED EDITION VHS TAPES Due to that fact there are not many copies of each tape, certain VHS tapes have become rather valuable. Overwhelmingly the majority of films are the horror genre with many banned quickly after their release. We suggest looking for VHS tapes that never made it to DVD or Blue-ray. SO WHY ARE VHS BECOMING VALUABLE? VHS collectors cite that current movies feel too cleaned-up on DVD and Blu-ray. They enjoy the mistakes made and the bad makeup and imperfections. Watching them on VHS is closer to the old drive-in or grind-hous
