audiorestauración

Our studio is specializing in the digitalization of analogical supports of audio recordings and later digital restoration. We rely on the best systems of conversion analogical digital, samples up to 192khzs and resolution of 24bits to obtain the purest and exact sound. Public and private music libraries, institutions, publishing editorials trust in our systems of digitalization and professional restoration. We follow strict international protocols to obtain the most faithful and rigorous sound, without spoiling the recording in origin.

From ends of the S. The XIXth, after the appearance of the primeiros patent systems of sound recording for Thomas A. Edison, Oberlin Smith or Emile Berliner, there was an increasing evolution of the same ones, what I derive in unha great variety of formats: Wax cylinders diferentes in diameter, speed of reproduction, etc. shellac disk of diverse types, broad of rut, speeds. Wire reels of sound. Magnetic tape, reel to reel with different composicións, tracks, speeds, broad, etc. Sound cassettes type Muntz, Nab broadcast, RCA-Victor, Playtape, Sabamovil, Tefi, etc.
In cassette type philips, minifon, XL2, Elcaset, etc.

To digitize wax cylinders: The basic parameters for digitalization happens for dominating the diverse compositions (wax, celluloid...), brands with his peculiarities (Edison, Pathé, Columbia ...), his special fragility (contrasts of temperature provoke breaks), the diverse sizes (ej. Saloon 20th Century), the speed diversity of rotation (160rpm, 120rpm ...), etc.

To digitize shellac discs: For a correct digitalization we must bear in mind diverse and complex parameters: his composition (cardboard, resin, nitrate, aluminium, vinyl ...) his cut (vertical, lateral, etc.), the width of rut and the adequacy of the needle, his(her,your) speed of rotation (there is false the belief of which they turn to 78rpm, the speed diversity is very wide, among the 62 rpm and them 100rpm is very habitual). An incorrect adjustment generates an unreal sound.The curves of compensation used (up to the appearance of the curve RIAA, which has standardized the discs of vinyl, numerous curves have used of ecualización, different without the correct selection of the same one, the result will be a sonorous incorrect product.) analysis of the type and calibre of rut to adapt the cápusla and necessary needle. We possess(rely on) technology of tangential reading, and slide for air suspension to pressure, obtaining the maximum precision.

In the image it is possible to see the measure of the calibre of a rut, adapt the type of needle adapted to his reproduction.

To digitize a wire recorder reell: how predecessor of the magnetic recording in tape, the cable of steel supposes a peculiar support where numerous sonorous files have registered. We rely on technology to digitize any type of bobbin in this format. In the Institute Valenciá of the Music there remain sonorous historical files in this teachers' support of Manuel Palau's height among others digitized in our studios..

To digitize open reels; The basic parameters for an objective digitalization it is based on the previous investigation(research) of the type of composition (paper, acetate, polyester ...) track configuration (NAB, din butterfly Stereo 0.75mm, Fulltrack, etc.) the speeds of reproduction (1-7/8, 3-3/4, 15/32, 7-1/2, 11-1/4, etc., the curves of equ (IEC, AES, AME, NAB ...)

The employment of encoders in the recording must be decoded to avoid to spoil the sound (Dolby, C4 Telcom, Dbxetc.) type of hub: AEG, NAB, CINE, NAGRA.

When we lack technical information of the open reel,, we rely on technology, since they are the magnetic visors that provide to us precise information about the number of tracks and calibre of the same ones. With it we select the system of reproduction adapted to the same ones.

To digitize cassettes: the formats of cassette include a great variety of formats, probably the compact cassette type Philips, it is most known. Our studio has aptitude to digitize any type of format of magnetic compact tape: RCA-Victor, Nab broadcast, Muntz, 8 tracks, microcassette, Play covers, Tascam portaestudio, etc. systems of encoder that must be exact.
