The focus is on the second stage of his career, no long dedicated to music, but to sounds and to hear, with the proposal to elaborate the concept of "audio-image". For this, he proposes a corpus that is composed by the radio masterpiece and then book "Nada Brahma – Die Welt ist Klang" (called "Nada Brahma: o mundo e o universo da consciência" in the Brazilian edition). With the justification that the visual images do not seduces the glances anymore due to the high speed of dissemination in contemporary cultural environments, this thesis investigates another approach about the image, able to contribute to a theory of audio images, which looks very necessary due to sound obscuring in the profusion of audio-visual media. In this sense, in addition to present the ideas of the German author in the domain of the communication's research in Brazil, this thesis defines the hearing experience as a resistance strength against the hegemony of visual images. Thus, it approaches the thought of Berendt to the Dietmar Kamper one, both in dialog with the thought of Norval Baitello Jr. in his theory of the image and culture. As his own reference, Baitello Jr. presents Berendt, extending the dialog with other thinkers as Harry Pross, which includes the body in its sensorial perception as primary media in its media classification, and Kamper himself, when announces the return to the hearing as a way of combating the "suffering" of the eyes. Thereby, the thesis proposes a concept of sound image close to a science called, by Hans Belting, "Anthropology of Image", where the sound appears as a vehicle of culture. For an understanding of the sounds and the media, the research uses the work of musicologists and sound engineers R. Murray Schafer and Michel Chion, which do not reduce the understanding of sound to the field of tradition of music. The theoretical framework also includes the authors cited by Berendt and his commentators, like the philosopher Peter Sloterdijk, the historians Andrew Right Hurley and Uta G. Poiger, in addition to the maestro and musicologist Julio Medaglia. We propose therefore a reflection about the restoration of relations and links broken in the light of the new culture of media / O objetivo desta pesquisa é fazer uma análise crítica acerca da obra literária e midiática do radialista alemão, especialista em jazz, Joachim-Ernst Berendt, com foco na segunda fase da sua carreira, não mais dedicada à música, mas aos sons e ao ouvir, com a proposta de elaborar o conceito de ‘áudio-imagem’. Para tanto, propõe um corpus composto pela peça radiofônica e depois livro, Nada Brahma – Die Welt ist Klang (denominado na edição brasileira, Nada Brahma: o mundo e o universo da consciência). Com a justificativa de que as imagens visuais já não mais seduzem os olhares devido à alta velocidade de disseminação nos ambientes culturais contemporâneos, essa tese investiga outra abordagem acerca da imagem, capaz de contribuir com uma teoria das imagens auditivas, que parece muito necessária frente o ofuscamento sonoro na profusão das mídias audiovisuais. Nesse sentido, além de apresentar as ideias do autor alemão no âmbito das pesquisas de comunicação no Brasil, esta tese define a experiência auditiva como força de resistência à hegemonia das imagens visuais. Aproxima, assim, o pensamento de Berendt ao de Dietmar Kamper, em diálogo com o pensamento de Norval Baitello Jr. na sua teoria da imagem e da cultura. Como própria referência, Baitello Jr. apresenta Berendt, ampliando o diálogo com outros pensadores como Harry Pross, que na sua classificação da mídia inclui o corpo em sua percepção sensorial como mídia primária e o próprio Kamper, quando anuncia o retorno à audição como forma de combate ao “padecimento” dos olhos. Assim, a tese propõe um conceito de imagem sonora próximo de uma ciência denominada, por Hans Belting, “Antropologia da Imagem”, onde o som aparece como veículo da cultura. Para uma compreensão acerca dos sons e da mídia, a pesquisa se vale dos trabalhos dos musicólogos e engenheiros de som R. Murray Schafer e Michel Chion, que não reduzem o entendimento de som ao campo da tradição da música. O referencial teórico inclui ainda os autores citados por Berendt e seus comentadores, como o filósofo Peter Sloterdijk, os historiadores Andrew Right Hurley e Uta G. Poiger, além do maestro e musicólogo Júlio Medaglia. Propomos, assim, uma reflexão acerca do restabelecimento de nexos e vínculos rompidos frente à nova cultura das mídias

Family conversation between homes is difficult to initiate at mutually agreeable times as neither participant has exact knowledge of the other's activities or intentions. Whether calling to plan an important family gathering or simply to connect with family members, the question is: Is now a good time to call? People expect friends and family to learn their activity patterns and to minimize interruptions when calling. Can technology provide awareness cues to the caller, even prior to the initiation of the call? This research focuses on sampling the everyday activities of home life to determine environmental factors, which may serve as an indicator for availability. These external factors may be effective for identifying household routines of availability and useful in determining when to initiate conversation across homes. Several workplace studies have shown a person's interruptibility can be reliably assessed and modeled from specific environmental cues; this work looks for similar predictive power in the home. Copresence, location, and activity in the home were investigated as correlates to availability and for their effectiveness within the social protocol of family conversation. These studies indicate there are activities that can be sensed, either in real-time or over some time span, that correlate to self-reported availability. However, the type and amount of information shared is dependent upon individual preferences, social accessibility, and patterns of activities. This research shows friends and family can improve their predictions of when to call if provided additional context, and suggests that abstract representations of either routines or explicit availability status is sufficient and may be preferred by providers. Availability prediction is feasible in the home and useful to those outside the home, but the level of detail to provide in particular situations needs further study. This work has implications for the development of groupware systems, the automatic sensing of activity to deal with interruption, and activity recognition in the home.

This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. The reader should also get a better understanding of how an AD-converter samples the incoming signal to the Discrete plane and how an AUX or phone connector works. This information can be used for designing preamp circuits to communicate between a computer and the DSP. The DSP circuit uses an STM32 processor to control the incoming and outgoing signals with the use of ADC and DAC conversion. The DSP also uses microphones to capture surrounding sound. An addition is to make a prototype on how to use these microphones to  send the signal upstream to the computer. The microphone is then benchmarked with the use of Matlab, calculating Total Harmonic Distortion. Management and optimization of code structure and resources is done in the source files of the project. Using imperative C programing, large functions are broken down into smaller functions to ease readability and control flow. The result is a prototype circuit that can communicate audio signals with both audio jack and USB between computers input and output to the DSP. Using CubeMX in conjunction with CubeIDE to add additional ADC channels to be able to incorporate an automatic source control when the audio jack or USB is connected. / Denna avhandling handlar om att designa en prototyp och etablera ljudkommunikation mellan en dator och en digital signalprocessor (DSP) med hjälp av två förstärkarkretsar genom både aux- och USB-anslutning. Rapporten ger läsaren en översikt över hur ljud skickas från en dator, genom systemet och till önskad utgång. Läsaren bör också få en bättre förståelse för hur en AD-omvandlare fungerar för att sampla den inkommande signalen till tidsdiskreta planet och hur en AUX- eller telekabel fungerar. Målet är att använda denna information för att skapa förstärkare som kan kommunicera mellan en dator och DSP:en. DSP-kretsen använder en STM32-processor för att hantera de inkommande och utgående signalerna med användning av ADC- och DAC-omvandling. DSP:en använder också mikrofoner för att fånga omgivande ljud. Ett tillägg är att skapa en prototyp för hur man kan använda en av mikrofonerna för att skicka signalen till datorn. Mikrofonen jämförs sedan med hjälp av Matlab genom att beräkna total harmonisk distorsion. Hantering och optimering av kodstruktur och resurser görs i projektets källkodsfiler. Genom att använda imperativ C-programmering bryts stora funktioner ned i mindre funktioner för att underlätta läsbarheten och styrningen av flödet. Resultatet är en prototypkrets som kan kommunicera ljudsignaler med både ljuduttag och USB mellan datorns in- och utgång och DSP:en. Genom att använda CubeMX tillsammans med CubeIDE läggs ytterligare ADC-kanaler för att möjliggöra automatisk källkontroll när ljuduttaget eller USB-anslutningen är ansluten.
