Perancangan Video Promosi Objek Wisata Ranudi Kabupaten Probolinggo Jawa Timur

Pesatnya kemajuan teknologi informatika (IT) memberikan kemudahan dalam mengakses dan menyajikan informasi dalam berbagai bentuk dan media, secara umumnya (buku, brosur, majalah, tabloid, dan poster), maupun dalam bentuk format elektronik atau digital (internet, film, cd-interaktif dan game). Dengan tersedianya banyak penyajian maka data hasil-hasil penelitian dapat disajikan dengan lebih menarik dan mudah digunakan maka data hasil-hasil digunakan, seperti mengandung unsur informasi Media ini berupa video promosi tentang Objek Wisata Ranu di Kabupaten Probolinggo-Jawa Timur. Video memberikan info tantang wisata Ranu di Kabupaten Probolinggo-Jawa Timur. Media promosi ini nantinya akan disajikan berupa video promosi dan informasi yang nantinya dapat memudahkan para wisatawan untuk mengetahui tentang WIsata Ranu di Kabupaten Probolinggo-Jawa Timur dan bertujuan untuk memikat daya tarik para wisatawan baik lokal maupun mancanegara untuk datang dan berpariwisata di Kabupaten Probolinggo. Format MPEG (MotionPicture Expert Group) dipilih karena memiliki beberapa kelebihan, diantaranya MPEG merupakan standart international untuk format digital audio & video, biasanya digunakan untuk VCD & DVD. Dalam membuat sebuah video sebagai media promosi yang menarik, media ini dibuat dengan beberapa elemen seperti konsep videografi, storyline, storyboard, dan audio. Software pendukung pada tahap pasca produksi adalah Adobe After Effect untuk membuat opening, Adobe Photoshop untuk mendesain informasi, dan Adobe Premiere Pro digunakan untuk proses editing video. Dari hasil responden, nilai presentase dari masyarakat menanggapi baik tentang produk yang dihasilkan, sehingga diperoleh penelitian akhir 97% mengatakan bahwa video ini menarik perhatian mereka dan layak menjadi Media Promosi objek Wisata Ranu di Kabupaten Probolinggo.

Web Page Design Recommendations for People with Down Syndrome Based on Users' Experiences.

At present, there is a high number of people with Down syndrome interested and trained to be an active part of society. According to the data extracted by our surveys we know that only 6% of the population with Down syndrome feels isolated in daily activities. However, when the activity requires the use of a computer, the percentage of people who feel isolated increases to 18%. This means that there are obvious website accessibility barriers that make it difficult for users with Down syndrome. To solve this problem, it is considered necessary to make an exhaustive study about Down syndrome. We know that the trisomy of chromosome 21 causes a series of symptoms that directly affect ones Internet browsing capabilities. For example, speech disturbances make communication and speed difficult. This guide is based on a neurological study of Down syndrome. Alterations in listening make understanding audio, retention of audio concepts and speed difficult. The alterations in the physiognomy of movement make it difficult for them to act quickly. Many of these alterations are caused by cognitive disability. After assessing the needs, the benefits of Web Content Accessibility Guidelines 2.0 (WCAG 2.0), and the existing usability guidelines are analyzed and those that may be useful for this profile are extracted. User tests are carried out through two websites developed specifically for this study with the aim of demonstrating the level of effectiveness of each of the planned guidelines. Considering the neurological characteristics of this intellectual disability, research is developed that seeks to extract a list of useful accessibility and usability guidelines for web developers.

Introducing programming through acoustics and audio at Belmont University

A course in computer programming has been offered within the department of Audio Engineering Technology at Belmont University to provide an introduction to audio and physics students interested in learning about programming. This course is based on a foundation of acoustics and audio concepts, without requiring previous programming experience. The pedagogical approach has been to expose students to the application of programming within their discipline of interest as a motivation for further exploration. Topics in the course introduce programming concepts for specific signal processing methods. Programming concepts include: variables, operators, data types, as well as basic control structures like loops, conditional statements and functions. While learning programming concepts, students perform various signal processing methods such as: changing a signal’s amplitude, signal synthesis, stereo panning functions, mid-side processing, amplitude fades, amplitude modulation, soft/hard clipping, rectification, bit reduction, echo effects, convolution, algorithmic reverberation, expander/compressor dynamic-range processing, and various spectral filters. Course lessons for a “flipped classroom” are freely and publically available at http://www.hackaudio.com/. Since the initial offering of this course, the number of students in the audio engineering program who double-major or minor in computer science has quadrupled.

Automatic environmental sound concepts discovery for video retrieval

This paper characterizes a new method for video–soundtrack retrieval based on environmental sounds. Actually, a set of 26 semantic audio concepts is employed. This set is chosen for its helpfulness to the users in terms of video browsing. Additionally, a set of 2000 videos has been annotated with these concepts. To enhance a new signal processing, we start with the separation of the audio sources. In addition, using a fundamental representation of the audio signal as a sequence of Mel Frequency Cepstral Coefficient, we can carry out experiments with three signal representations: the Support Vector machines, the Gaussian Mixture Model and the Hidden Markov Model. Throughout the experiment synthesis, we maintain the Gaussian Mixture Model classifier based on the Kullback–Leibler distance measure. As a matter of fact, we preserve this audio concept classification to integrate a video retrieval system. Hence, the obtained results mirror the effectiveness of our approaches in distinguishing environmental sound and researching video.

Enriching the aural experience in audio education

Audio education’s essential outcome is aural. Lectures and readings on aesthetics, techniques, and technologies can never communicate audio concepts effectively without critical elucidation through sound. Quality audio education has always made frequent use of laboratories, recording sessions, and critical listening classrooms to keep sound at the center of student learning. Recently authored and published web-based multimedia and digital audio workstation self-study experiences are discussed and demonstrated. The sonic illustrations, visual reinforcement, and associated interactivity are found to provide meaningful pedagogical advancements in audio education.
