A large number of people own a portable digital audio player - in a recent market report by In-Stat the worldwide unit sales were predicted to be 286 million by 2010. Music collections on these devices are also sizeable, typically with many 1000s of songs. The songs are grouped together in various ways: historically as albums, but more recently in playlists either generated automatically by software, or generated by the user. The challenge with large groups of songs is to navigate effectively though the group, or playlist, to select the song, or songs of choice.Currently users interact with playlists through a visual interface - the screen on the front of the device. Proposed in this application is a purely audio means of interacting with a playlist. The user browses through the songs in the playlist, listening briefly to each and selecting the songs of choice. This is achieved by using 3D audio technology, which plays several songs simultaneously as if they were originating from different spatial locations. From trials of an early-stage prototype of the technology it has been established that 4 songs playing at the same time, located using virtual acoustics in different virtual positions around the listener's head, is the optimal set up. The user can then easily navigate around the 3D virtual sound space, either using buttons on the device, or by pointing and tilting the device appropriately, if it contains an accelerometer (or similar), as increasingly many devices do, including the iPhone and iPod Touch.The funding will be used to further develop the technology, ultimately so that it runs on a stand-alone hand-held device. This can then be demonstrated to potential licensees. We also intend to release a limited functionality version free from our isophonics web portal, which currently offers our SoundBite automatic playlisting tool. This limited functionality release will enable potential customers and end-users to trial the software before purchase. Additionally, it will enable us to engage with end-users, seeking their feedback for improving the software.The technology will be commercially exploited by licensing the software as an API. One of the commercial issues addressed by the work plan presented in this proposal is whether a spin-out company should be established as a licencing vehicle, or whether direct exclusive licensing to an major mobile handset manufacturer, such as Nokia is more appropriate.

许多人拥有便携式数字音频播放器--在In-Stat最近的一份市场报告中，全球销量预计到2010年将达到2.86亿台。这些设备上的音乐收藏也是相当大的，通常有数千首歌曲。歌曲以各种方式分组在一起：过去是作为专辑，但最近是在由软件自动生成或由用户生成的播放列表中。大组歌曲面临的挑战是如何在组或播放列表中有效导航以选择歌曲。目前，用户通过可视化界面--设备前面的屏幕--与播放列表交互。在本申请中提出的是与播放列表交互的纯音频手段。用户浏览播放列表中的歌曲，简短地收听每首歌曲并选择所选择的歌曲。这是通过使用3D音频技术实现的，该技术可以同时播放几首歌曲，就像它们来自不同的空间位置一样。从对该技术的早期原型的试验中已经确定，使用虚拟声学技术在听者头部周围的不同虚拟位置同时播放4首歌曲是最佳设置。然后，用户可以轻松地在3D虚拟声音空间中导航，要么使用设备上的按钮，要么通过适当地指向和倾斜设备，如果它包含加速计(或类似设备)，就像越来越多的设备，包括iPhone和iPod Touch。资金将用于进一步开发这项技术，最终使其在独立的手持设备上运行。然后可以向潜在的许可证持有者演示这一点。我们还打算从我们的isophonics门户网站发布一个功能有限的免费版本，该门户网站目前提供我们的Soundbit自动播放列表工具。这一功能有限的版本将使潜在客户和最终用户能够在购买前试用该软件。此外，它还将使我们能够与最终用户接触，征求他们对改进软件的反馈。这项技术将通过将软件作为API授权进行商业开发。这项提案中提出的工作计划涉及的商业问题之一是，是否应该成立一家剥离公司作为许可工具，或者直接向主要手机制造商(如诺基亚)发放独家许可是否更合适。
