In the past decades, high quality digital audio systems, array speakers and computer aid simulations created greater flexibility where high-quality audio systems were in demand. Nowadays, array speakers with their cylindrical sound propagation are more popular in large halls due to lower sound attenuation by distance (3dB attenuation with doubling the distance) and their ability to produce a wide range of frequency bands and physical coverages. 2021-03-17T00:00:00Z https://hdl.handle.net/2123/24666 Individual major audio production project Ghanavi, Reza The main sound design ideas for the provided short episode of Cosmos War of the Planets, directed by Alfonso Brescia (1978), have been developed based on the existing visual cues to reflect realistic acoustics by creating mysteries sound effects and music. 2021-03-17T00:00:00Z https://hdl.handle.net/2123/6851 BDES3020 'inside' <DaRong, Chen> Chen, Da Rong Life is a SECRET.... 2010-11-10T00:00:00Z https://hdl.handle.net/2123/22958 Application of Adaptive System to ECG Analysis: Noise Attenuation and ECG Detection Ji, Xinyu ECG or electrocardiogram is a tool used to monitor the electrical activity of a heartbeat.

This means it is necessary to design a filter for better attenuating the noise below and beyond a certain frequency. Moreover, the abnormal ECG results from abnormal heart rate is the best notification for any potential heart diseases and should get notice as soon as possible.

But what is it about Venice that keeps the masses coming back? The romance of the city at night; the serenity derived from the lack of motored transport; the winding maze of canals, not to mention streets; the large, open piazzas; the historic architecture; the rich culture. Whether it is one of these reasons or another, we can be sure that one quality prevails above all else: the innate sense of mystery that is bred into Venice. And La Scatola di Vetro doesn’t fail to live up to this expectation. Picture this: Imagine sitting in San Marco Piazza; sipping on a perfectly brewed Italian coffee whilst watching the pigeons pass by. One takes flight, and you follow it with your gaze, when all of a sudden, a glimpse of something exciting and magnificent appears, hovering above the roofline of the Procuratie Nuove. You are intrigued. You wish to discover what mysteries this floating glass box has to offer. You see people moving up glass elevator shafts in order to enter the building, but from where you are sitting, the entry is not clear. You quickly finish the rest of your coffee; throw down a handful of the complimentary peanuts; pay the bill, leave a tip; and off you head, looking for the entry. This action in itself becomes the first little mystery wanting to unfold! You enter the Procuratie Nuove, when all of a sudden ... you are confronted with the lifts – the circulation up to this undiscovered world. The ride up is eventful – the layers of this historic building begin to unfold – when suddenly, you break through the roof and are now passing through the sky. The city of Venice begins to be revealed – a perspective of it you haven’t seen before. From here, the city looks very consistent, but it is beautiful in every sense. After ascending some twenty-odd-meters, and upon entry to the building, you are greeted by some marvellous works of art – the most exquisite Italian and Murano glass exhibits to be exact. Though, taking the time to admire these works of art has not kicked in yet – you are still mesmerised by the view that can be seen out of the full curtain wall glass facade. It opens up a whole new perspective of Venice you never previously conceived possible – one that looks over the whole city, coming to expose: San Marco Basilica and the Piazza to the north-east; Santa Maria della Salute to the south-west; and suburban Venice to the north-west; with all of these marvels gradually becoming apparent as you circulate your way around the 67 meter long building. When you settle down and take the time to admire the glass exhibits, you come to realise they are exquisite; they are strong but fragile; and they have a unique, yet simplistic form - all qualities of the building in which they are housed. Whilst the structure of La Scatola di Vetro¬ may appear to be a rectilinear element of prosaic simplicity, core pods (used to define areas of distinct activity), give the structure a form that is memorable and functional. A form that is divided over two levels and leaves the exterior floor space open for circulation and uninterrupted views of Venice. You can visit one of the three distinct exhibition spaces; see how it is all made in the glass blowers workshop – or if you are game – have a go at creating your own little souvenir as a take-home memory of today’s adventure. But if, after all that, you wish to put your feet up; take a seat in the cafe on the upper mezzanine level and begin to take in the city of Venice from a light, airy, uncluttered, aerial perspective. You will be overwhelmed by a sense of content; so it is only fitting that you exit via the second set of lift cores which present themselves in the Giardini Landscaped Reserve – and while you are there, why not take a stroll in the park, or lie on the grass and admire the qualities in your hand-made souvenir. Not to mention admiring the way in which the building is held up by a scattered array of slender concrete columns which slide seamlessly with the trunks of the trees in the reserv¬¬e. So with a brief tour of La Scatola di Vetro put forth, – it’s now time to discover for yourself The Fragile Mystery.

As opposed to the prior uses of this audio effect, the aim of this project is to develop a system by using the effect of Vibrato, which gauges fitness levels in athletes by sonifying their heartbeats/minutes data. Heartrates in athletes vary due to their fitness levels and there are tools like smartwatches that measure them however there is lack of fitness tools that can promptly measure and produce a direct outcome that can provoke them promptly towards higher goals. This project investigates how vibrato can be used as an effect to enhance this proposed system’s effectiveness in pushing athletes further towards their goals. In this project the main object is to devise a system that can translate a set of heartrate data into sounds through user input.

This six-level building is constructed of a reinforced concrete frame and level 4 with 1866 m^2 is about 15.5% of the total building floor area. This level consists of Studio 405 and several other offices and facilities. The main entrance of Studio 405 is in lobby 400 which is accessible from either staircase 400A or the elevator. The total volume of the Studio is 2025 m^3 (H=3.6m from floor to floor) and its usable volume is 1599m^3 (H=2.8m from floor to the false ceiling). The net usable area of Studio 405 is about 569m^2. The studio is connected to fire exit stairs 430 & 440 from the west and south sides. The studio has a high angle view (H~19m) to Maze Crescent Roade from the southern and eastern windows and limited view to City Road from the southwestern windows. The shape of the Studio is similar to an irregular pentagon with three right angles. A smaller scaled, identical polygon structure (windows area = 62 m^2) is located at the center of the studio. Skylight Dome for capturing daylight energy for the surrounding zones is located directly above the central structure. Glass windows constitute the majority of the south-eastern to north walls (100 m^2) but 30% of these windows are internally shaded by the false ceiling. 17 awning windows conduct the prevalent south eastern and northern winds into the building. The southwestern part of the Studio is connected to the outside courtyard through several windows (12.5m^2) including three awning windows which are the only openings toward prevalent western winds. A narrow window (8.5m^2) is placed on the studio’s southern wall and awning windows on this wall are not usable (locked). All windows are made of aluminum frames and glazed with 6mm tinted glass. The window to wall ratio for tall walls with windows is 0.34. The studio’s floor is covered with a dark carpet and the main area has been partitioned into several adjustable zones. Each partition consists of two or three blocks (1.7*0.6*2m). These blocks are wooden shelves and their back sides are covered with PET (Polyethylene terephthalate) felt panels with 1cm thickness. Students can place their belongings in the shelves and pin sheets on the PET panels. These panels can also absorb sound energy. In addition, the southern walls are all covered with the same material. The false ceiling acoustic panels are made of compressed straws. Fluorescent lights and other facilities such as fire sensors, wifi boosters and air conditioning vents have been installed on the false ceiling and other related electro-mechanical systems and ducts have been installed behind the false ceiling. The artificial illumination of the studio is provided with a total number of 260 (252 *38 W + 8 * 20W) florescent lamps. Studio 405 is used for a variety of functions. The division of the space into factions makes it suitable for use as classrooms where lessons, presentations, seminars and workshops are carried out. Currently, 100 white portable study tables are in use in the studio which provide a total of 162m^2 of desktop space for up to 150 users. The flexible arrangement of furniture allows for groups to use this space for meetings and discussions. There is no computer room in this studio and students use their own devices. There are 9 portable large screen monitors and a sun emulator for educational purposes. 2018-11-26T00:00:00Z https://hdl.handle.net/2123/19861 Sonification of Real-Time Physiological Data for Meditation Practice Ghanavi, Reza Translating biophysical data to meaningful audible pieces has been under investigation in plants, animals and humans [2].

One of the known objective methods for evaluating speech intelligibility inside cars is the speech transmission index STI which is the main subject of this report. The measurement aim is to predict the STI in a running car as a factor of speed (background noise). For this purpose, a series of audio- acoustical measurements have been conducted inside a five-door car (Mazda) based on the European standard IEC 60268-16 [4]. As the harshness of background noise in different speeds, compartment reverberation time and speech level are accounted for in the STI calculation, the resulting data can be interoperated as the quality of sound in the car [6]. Further investigations have been done for better understanding the effect of source spectrum and direction on the transmission index and finally the direct measurement method in aarae has been compared with a similar method in Arta (Audio Measurement and Analysis Software) in the room space. 2018-11-26T00:00:00Z https://hdl.handle.net/2123/19862 Video Game Audio Ghanavi, Reza Game sound is the last step in game production industries which plays an important role to enhance the sense of immersion or emotional involvement in most recent games.

The main expectation of this APP can achieve sound, Window type, Spectrogram and Waveform real-time contrast and the diagram (or sound) fast switching. Later stages can be developed as a stand-alone vocoder, or as a Third-party plug-in. Hence, there are three problems in here. Firstly, what is the principle of the phase vocoder? Then, how to implement it in MATLAB? Finally, how to integrate these function into the GUI interface. The results show that GUI interface as expected, waveform, spectrogram, sound and window functions can appear simultaneously, and switching speed as expected. The drawback is that the overall design of the interface is not very intelligent, so it needs to be improved in the future. 2018-06-08T00:00:00Z https://hdl.handle.net/2123/18348 Final Proposal of a new natural equalizer Zhang, Yingda 2018-06-08T00:00:00Z https://hdl.handle.net/2123/18345 DESC9115 -Final Proposal-Virtual Studio Sound with Headphone Frew, Alexander The below product proposal is inspired by the Waves NX application and plugin (Waves, 2018).

Fast turnaround is crucial. For this reason, it is standard practice for producers and sound designers to maintain libraries of pre recorded sounds. Whether those sounds have been purchased as sample libraries or recorded by the end user, it may be necessary that they undergo various types of signal processing to minimize any additional mixing required once they are loaded into to a production. A common example is that of a commercially available drum sample library. Often the hi-hat samples are monaural, or feature a very narrow stereo image, and can also contain unnecessary low frequency information. These issues can be remedied in the production session once the samples have been added, but this interruption to workflow can limit creativity and reduce operational efficiency. This product has been developed as a solution to this problem. It is intended to batch process large numbers of audio files to prepare them for later use. The signal processing modules are implemented in what is known as a multiband processing network, which consists of several sets of parallel signal processing chains that each work on a different part of the frequency spectrum. This allows for a higher degree of control than processing the entire broadband signal. The central concept is that what is considered a desirable sonic characteristic for one part of a signal’s spectrum, may not be desirable for another. An exaggerated stereo width effect for example, may be desirable in the high-mid frequency range of a bass synthesizer sound, and this can be created using an inter- aural time difference. In the low range however, the phasing introduced by this delay between channels will result in an unintended loss of low frequency information. Multiband processing eliminates this problem. 2016-06-06T00:00:00Z https://hdl.handle.net/2123/15029 Zen-Flanger Xi, Peng 2016-06-06T00:00:00Z https://hdl.handle.net/2123/15038 Simple HRIR Filter Achieved with the Data of KEMAR Li, Junting Jr The HRIR filters are widely used in many fields today, for example, some ASMR recordings and stereo songs mixing. My function provides a simple HRIR filter that could make a mono recording mixed into a stereo, binaural recording with relatively accurate positioning using the data of Knowles Electionics Mannequin for Acousitc Research (KEMAR). 2016-06-06T00:00:00Z https://hdl.handle.net/2123/15036 Auto-wah envelope filter software Adlington, Isabella 2016-06-05T00:00:00Z https://hdl.handle.net/2123/15035 Final Written Review, Digital Audio Systems DESC9115, 2016 Pereira, Frederico A granular synthesis prototype is described The prototype applies the granulation algorithm to a given input audio signal, and outputs up to four channels of audio. The signals in the different output channels can be decorrelated, in order to achieve a superior subjective spatial impression. 2016-06-06T00:00:00Z https://hdl.handle.net/2123/15027 Bandpass Limiter Vyas, Neil Bandpass Limiter is a limiter that has a bandpass filter included in its design. When an audio signal is input into the limiter, it band-passes the audio signal before it gets to the limiter stage. The Bandpass Limiter can process mono as well as stereo files and it gives the user an option to use it as a mastering limiter as well as a bandpass limiter, where the low cut and high cut frequencies are defined by the user. All the parameters of the limiter like limiter threshold, attack time and release time can be defined by the user. Main function, supporting function, working example script and example audio files can be found attached. 2016-06-06T00:00:00Z https://hdl.handle.net/2123/15034 Four Input Amplitude Modulator Holmes, Jonothan This report presents the requirements and assessment of the various processing necessary for an audio effect described here as the four input amplitude modulator.
