Putting it down: the making of a cd with special reference to Hendrik Hofmeyr's Notturno elegiaco for piano trioNay, Malcolm 02 September 2009 (has links)
M.Mus. Faculty of Humanities, University of the Witwatersrand, 2008 / The broad structure of this reflexive essay is twofold: First I discuss my experience of making a compact
disc (CD) recording with the Trio Hemanay, which consists of three performer-musicians – Marian Lewin
(cello), Helen Vosloo (flute) and myself, Malcolm Nay (piano), and second I offer an analysis of Hendrik
Hofmeyr’s Notturno Elegiaco for Piano Trio, a work composed specifically for the Trio Hemanay,.
I draw on writings of other performers and recording artists, who have contemplated and engaged with the
recording process, in order to place myself, the Trio and our music-making within a South African
context. I further contextualise the Trio with reference to other well-known performing ensembles in
South Africa.
I refer to the inception and constitution of the Hemanay Trio and give some insights into aspects that
inform the aesthetics and rationale of its establishment and existence. I also discuss the practicalities of
financing and producing such a recording, and the extent to which non-musical issues inevitably impact
on the artistic outcome. I further elaborate on the value of documenting music through recordings, both
from a personal and from an objective perspective, and I reflect on what I have learnt from the recording
experience; where relevant, I collate this with the experience of my two colleagues. In Part II, I offer an
analysis of the musical content and a stylistic scrutiny of Hendrik Hofmeyr’s Notturno Elegiaco, recorded
by Trio Hemanay on the CD under discussion (the only current recording of this work).
This essay is written in a narrative form, which allows me to discuss the inception of the recording, the
development of the process and the elements that have contributed to the acquisition of greater insights for
both me and for the Trio, all of which may influence future projects.

Real time microprocessor techniques for a digital multitrack tape recorderDonnelly, Terence January 1989 (has links)
Transport properties of a standard compact - cassette tape system are measured and software techniques devised to configure a low - cost,direct digital recording system. Tape - velocity variation is typically ± 10% of standard speed over tape lengths of 5 µm.with occasional variations of ±40%. Static tape - skew can result due to axial movement of the tape reel when it spools.Dynamic tape skew occurs and is primarily caused by tape - edge curvature with a constant contribution due to the transport mechanism.Spectral skew components range from 0.32 Hz to 8 Hz with magnitude normally within one 10 kbit/ sec- bit cell.The pinch roller works against the friction of the tape guides to cause tape deformation.Average values of tape deformation are 0.67 µm,0.85 µm and 1.08 µm for C60,C90 and C120 tape respectively. Parallel,software encoding / decoding algorithms have been developed for several channel codes.Adaptive software methods permit track data rates up to 3.33 k bits/sec in a rnultitrack system using a simple microcomputer.For a 4 - track system,raw error rates vary from 10ˉ⁷ at 500 bits/sec/track to 10ˉ⁵ at 3.33 kbits/sec/track.Adaptive software reduces skew - induced errors by 50%.A skew - correction technique has been developed and implemented on an 8 - track system at a track data rate of 10 k bits/sec. Real - time error correction gives a theoretical corrected error rate of 10ˉ¹¹for a raw error rate of 10ˉ⁷. Multiple track errors can cause mis - correction and interleaving is advised. Software algorithms have been devised for Reed - Solomon code. With a more powerful microprocessor this code m ay be combined with the above techniques in a layered error-correction scheme. The software techniques developed may be applied to N tracks with an N - bit computer.Recording density may be increased by using thin - film,multitrack heads and a faster computer.

A ROADMAP TO STANDARDIZING THE IRIG 106 CHAPTER 10 COMPLIANT DATA FILTERING AND OVERWRITNG SOFTWARE PROCESSBerard, Alfredo, Manning, Dennis, Kim, Jeong Min 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / High speed digital recorders have revolutionized the way Major Range and Test Facility Bases
collect instrumentation data. One challenge facing these organizations is the need for a validated
process for the separation of specific data channels and/or data from multiplexed recordings.
Several organizations within Eglin Air Force Base have joined forces to establish the
requirements and validate a software process compliant with the IRIG-106 Chapter 10 Digital
Recording Standard (which defines allowable media access, data packetization, and error
controls mechanics). This paper describes a roadmap to standardizing the process to produce this
software process, Data Overwriting and Filtering Application (DOFA).

AATIS AND CAIS DATA RECORDINGGaddis, William R. Jr, Sandland, Sawn 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / DOD flight test centers need affordable, small-format, flight-qualified digital
instrumentation recording solutions to support existing and future flight testing. The
Advanced Airborne Test Instrumentation System (AATIS) is today's primary data
acquisition system at the Air Force Flight Test Center (AFFTC). Digital Recorder
(DR) 1995 is planned to provide full support for AATIS output capabilities and satisfy
initial recording requirements for the Common Airborne Instrumentation System
(CAIS). The follow-on to the AATIS, the CAIS is a tri-service development to satisfy
future DOD flight test data acquisition requirements. DR 2000 is planned as the future
recording solution for CAIS and will be able to fully satisfy the 50 Mbps recording
requirement. In the developments of DR 1995 and DR 2000, commonality and
interoperability have emerged as significant issues. This paper presents an overview
of these recording solutions and examines commonality and interoperability issues.

625 MBIT/SEC BIT ERROR LOCATION ANALYSIS FOR INSTRUMENTATION RECORDING APPLICATIONSWaschura, Thomas E. 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / This paper describes techniques for error location analysis used in the design and testing of high-speed instrumentation data recording and communications applications. It focuses on the differences between common bit error rate testing and new error location analysis. Examples of techniques presented include separating bit and burst error components, studying probability of burst occurrences, looking at error free interval occurrence rates as well as auto-correlating error position. Each technique contributes to a better understanding of the underlying error phenomenon and enables higher-quality digital recording and communication. Specific applications in error correction coding emulation, magnetic media error mapping and systematic error interference are discussed.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / Magnetic tape is the primary medium used to capture and store unprocessed data from
remote sensing satellites. Recent advances in digital cassette recording technology
have resulted in the introduction of a range of data recorders which are equally at
home working alongside conventional recorders or as part of more advanced data
capture strategies. This paper shows how users are taking advantage of the
convenience, economy and efficiency of this new generation of cassette-based
equipment in a range of practical applications.

El uso e impacto de las técnicas de grabación y mezcla analógica en la producción musical estadounidense de pop y rock (2011-2017): Alternativas para su aplicación en el estudio digital / The use and impact of analog recording and mixing techniques in the American pop and rock music production (2011-2017): Alternatives for its application in the digital studioRodríguez Salinas, Roberto Javier 17 August 2020 (has links)
El presente trabajo de investigación trata de identificar y analizar la influencia y la aplicación del audio analógico en la producción musical contemporánea, abarcando diversos criterios: sonoro/técnico, de ejecución, social, de preservación o archivo, entre otros. A pesar de que el audio digital, y el uso derivado de las herramientas de edición y mezcla, se consideran el estándar en la industria musical actual, se conoce que un número importante de productores, ingenieros y artistas siguen empleando hoy en día las técnicas de grabación y mezcla analógica desarrolladas décadas atrás. Por ello, el audio analógico surge como una alternativa a los procesos de creación y producción musical modernos, tanto a nivel sonoro como de ejecución. Este trabajo parte del desarrollo técnico y estético en la grabación analógica, realizando comparaciones con su contraparte digital. Para ello, se toman en cuenta las opiniones y los procesos de producción de productores musicales y profesionales a cargo de las producciones discográficas más relevantes en los últimos años en el circuito norteamericano. Es en estas producciones donde se evidencia el uso creativo del audio analógico, así como su adaptación al entorno digital. Finalmente, se tiene en cuenta al productor independiente como principal beneficiario de esta publicación, quien conoce directa o indirectamente los beneficios del audio analógico, pero no necesariamente cuenta con los recursos para integrarlo a su estación de trabajo. Por ello, se busca brindar herramientas y soluciones para poder emplear e integrar las principales funciones del formato analógico y digital en una producción moderna. / The hereby thesis attempts to identify and analyze the influence and application of analog audio in contemporary music production by covering diverse criteria: sonic/technical, performative, social, of preservation or archive, among others. Although digital audio, and its derived use of editing and mixing tools, are currently considered standard in the music industry, it is also known that a significant number of producers, engineers and artists still employ analog recording and mixing techniques developed decades ago. Hence, analog audio presents itself as an alternative to the modern creative and production processes, at both sonic and performance levels. This work begins with the technical and aesthetical development within an analog recording, comparing it afterwards with its digital counterpart. To serve this purpose, the opinion and detailed production processes of renowned American producers and professionals, responsible for the most acclaimed records in the last ten years, are taken into consideration. Those records evidence the creative use of analog audio, as well as its adaptation to a digital setup. Finally, independent producers could benefit the most from the information and arguments in this paper, because they directly or indirectly know the benefits of working analog, even when they often lack the resources to acquire these tools. Therefore, the author attempts to bring tools and solutions for the application of analog and digital audio in a single modern production. / Tesis

Las nuevas tecnologías en la administración de justicia. La validez y eficacia del documento electrónico en sede procesalJaume Bennasar, Andrés 09 October 2009 (has links)
La tesis se encarga de analizar, por un lado, la integración y el desarrollo de las nuevas tecnologías en la Administración de Justicia; y, por otro, los parámetros que constituyen la validez y eficacia del documento electrónico. La primera cuestión se centra en la configuración de los Sistemas de Información de la Oficina Judicial y del Ministerio Fiscal, así como de la informatización de los Registros Civiles, donde el art. 230 LOPJ es la pieza clave. Se estudian sus programas, aplicaciones, la videoconferencia, los ficheros judiciales y las redes de telecomunicaciones que poseen la cobertura de la firma electrónica reconocida, donde cobran gran relevancia los convenios de colaboración tecnológica. La digitalización de las vistas quizá sea una de las cuestiones con más trascendencia, teniendo en cuenta que el juicio es el acto que culmina el proceso. Aunque no todos los proyectos adoptados en el ámbito de la e.justicia se han desarrollado de forma integral, ni han llegado a la totalidad de los órganos judiciales. El objetivo final es lograr una Justicia más ágil y de calidad, a lo cual aspira el Plan Estratégico de Modernización de la Justicia 2009-2012 aprobado recientemente.En referencia a la segunda perspectiva, no cabe duda que el Ordenamiento jurídico y los tribunales, en el ámbito de la justicia material, otorgan plena validez y eficacia al documento electrónico. Nuestra línea de investigación se justifica porque cada vez son más los procesos que incorporan soportes electrónicos de todo tipo, ya sea al plantearse la acción o posteriormente como medio de prueba (art. 299.2 LEC). Entre otros temas examinamos el documento informático, la problemática que rodea al fax, los sistemas de videograbación y el contrato electrónico. / La tesi s'encarrega d'analitzar, per una part, la integració i el desenvolupament de les noves tecnologies dins l´Administració de Justícia; i, per l'altra, els paràmetres que constitueixen la validesa i l'eficàcia del document electrònic. La primera qüestió es centra en la configuració dels Sistemes d´Informació de l´Oficina Judicial i del Ministeri Fiscal, així com de la informatització dels Registres Civils, on l'art. 230 LOPJ es la peça clau. S'estudien els seus programes, aplicacions, la videoconferència, el fitxers judicials i les xarxes de telecomunicacions que tenen la cobertura de la firma electrònica reconeguda, on cobren gran rellevància els convenis de col·laboració tecnològica. La digitalització de les vistes tal vegada sigui una de les qüestions amb més transcendència, tenint amb compte que el judici es l'acte que culmina el procés. Però no tots el projectes adoptats en l'àmbit de la e.justicia s'han desenvolupat d'una manera integral ni han arribat a la totalitat dels òrgans judicials. L'objectiu final es assolir una Justícia més àgil i de qualitat, al que aspira el Pla Estratègic de Modernització de la Justícia 2009-2012 aprovat recentment. En referència a la segona perspectiva, no hi ha dubte que l´Ordenament jurídic i els tribunals, en l'àmbit de la justícia material, donen plena validesa i eficàcia al document electrònic. La nostra línia d'investigació es justifica perquè cada vegada son més el processos que incorporen suports electrònics de tot tipus, ja sigui quant es planteja l'acció o posteriorment como a medi de prova (art. 299.2 LEC). Entre altres temes examinem el document informàtic, la problemàtica que envolta al fax, els sistemes de videogravació i el contracte electrònic. / The thesis seeks to analyse, on the one hand, the integration and development of the new technologies in the Administration of Justice; and, on the other, the parameters which constitute the validity and efficiency of the electronic document.The first question centres on the configuration of the Information Systems of the Judicial Office and the Public Prosecutor, as well as the computerisation of the Civil Registers, where the art. 230 LOPJ it's the part key. Their programmes, applications, the Video Conferencing, the judicial registers and the telecommunication networks which are covered by the recognised electronic signatures, are studied, where the agreements on technological collaboration gain great relevance. The digitalisation of evidence might perhaps be one of the questions with most consequence, bearing in mind that the judgment is the act by which the process is culminated. Although not all the projects adopted within the compass of e.justice have developed completely nor have reached all the judicial organs. The final objective is to achieve an agile, quality Justice, to which the recently approved Strategic Plan for the Modernisation of Justice aspires.With reference to the second perspective, there is no doubt that the juridical Ordinance and the tribunals within the compass of material justice grant full validity and efficacy to the electronic document. Our line of investigation is justified because there are more and more processes which are sustained by electronic supports of all kinds, whether it be at the establishment of the action or later, as a proof of it (art. 299.2 LEC). Amongst other things, we examine the computerised document, the problems which surround the fax, the systems for video recording and the electronic contract.
