Recently, recognizing user resource for personalized service has been needed in digital content service fields. Especially, to analyze user taste, recommend music and service music related information need recognition of user music file in case of online music service. Music related information service is offered through recognizing user music based on tag information. Recognition error has grown by weak points like changing and removing of tag information. Techniques of content based user music recognition with music signal itself are researched for solving upper problems. In this paper, we propose user music recognition on the internet by extracted feature from music signal. Features are extracted after suitable preprocessing for structure of content based user music recognition. Recognizing on music server consist of feature form are progressed with extracted feature. Through this, user music can be recognized independently of tag data. 600 music was collected and converted to each 5 music qualities for proving of proposed recognition. Converted 3000 experiment music on this method is used for recognition experiment on music server including 300,000 music. Average of recognition ratio was 85%. Weak points of tag based music recognition were overcome through proposed content based music recognition. Recognition performance of proposed method show a possibility that can be adapt to online music service in practice.

온라인 음악서비스가 유료화를 단행한 지 1년이 지났다. 지난해 7월 8개 온라인 음악사이트가 유료화를 단행한데 이어 지난 7월에는 국내 최대 온라인 음악사이트‘벅스뮤직’까지 유료화를 선언, 온라인 음악서비스의 유료화는 급물살을 타고 있다. 최근에는 한국음원제작자협회와 벅스뮤직간의 힘겨루기가 일단락되면서 온라인 음악유통 확대에 대한 기대감도 조성됐다. 국내외 온라인 음악 시장의 현황을 살펴봤다.

모바일음원콘텐츠는 모바일서비스와 함께 시작된 콘텐츠로 서비스 초기에 많은 CP들이 참여하여 급격한 시장 확대를 이루어 냈으나 2004년부터 성장이 멈추고 경쟁이 극심해져 많은 CP가 도태되는 부익부 빈익빈 단계로 접어들었다. 모바일음원콘텐츠의 경우, 최근 MP3폰의 보급이 확대되면서 온라인음악이라는 새로운 시장 개척이 활발해져 시장 확대에 기여를 하고 있으나 이동통신사의 매출증대에만 기여할 뿐 CP들의 매출에는 영향이 거의 없는 것으로 분석되고 있다.

온라인음악 서비스 시장의 유료화가 자리 잡아가고 있다. 아지도 온라인음악 서비스 업체. 음원저작권자, 소비자 간 날 선 대립과 갈등이 지속되고 있지만 온라인음악시장이 전체 음악시장을 주도할 것이라는 점에선 이견이 없는 듯하다. 이를 반영하듯 온라인음악업계는 차별화된 서비스를 기반으로 유료화라는 새롭게 변화된 환경에 점차 적응하는 모습을 보이고 있다.

최근 웹의 발달로 인해 과거 오프라인에서만 가능했던 서비스를 웹에서 다양하게 온라인으로 사용할 수 있게 되었다. 본 논문에서는 이러한 온라인 웹 서비스 중 음악 스트리밍 서비스를 통하여 노래방 프로그램 구현을 고려하고 있다. 노래방 서비스에서는 기존 음원에 사람의 목소리가 있는 경우 서비스에 활용하기 어렵다. 또한 기존 음악서비스에서 사용되는 대다수의 음원은 저작권을 통해 제공되는 서비스로, BGM 형태의 음악들을 제공받는 것은 힘들다. 이러한 문제점들을 해결하기 위해 목소리 제거 기능을 하는 스트리밍 서비스를 구현한다. 웹 환경은 어디에서든 서비스를 이용할 수 있다는 장점이 있다. 또한 사용자의 창작물을 다른 사람이 감상할 수 있도록 구현한다. 사람의 목소리를 제거하기 위해 사람 목소리의 대역폭을 제거하는 방법을 사용한다. 그리고, 웹서비스를 통해 사용자간의 소통을 수월하게 한다. 이 방법을 통하여 음악을 듣는 것뿐만 아니라 어떤 음악이든 인터넷을 통하여 사람들과 함께 부르는 것이 가능하다.

In recent years, the film industry in South Korea has experienced a period of prosperity, evidenced by the numerous awards won at major international film festivals. Furthermore, growing global interest in K-content and the expansion of the OTT industry following the COVID-19 pandemic are providing favorable conditions for the development of the domestic film industry. Sound effects play a crucial role in conveying the atmosphere and emotions of a film, making them an essential element of film production. In response, the Jeonju IT & CT Industry Promotion Agency has been promoting the development of Korean-style sound effects since 2013. Furthermore, the agency launched an online service called the "K-Sound Library," a sound effect archive, in 2021. However, the service has not been widely utilized because of issues with the database's construction and the system's problems. Therefore, this study aims to identify the K-Sound Library's problems through interviews with sound effects specialists about the online service of the first sound effect archive in South Korea. Based on the interviews and analyses of foreign cases, the study suggests ways to improve the search services' usability and the sound effects classification system.

These days, consumers have increasingly preferred to digital real-time streamlining and downloading to listen to music because this is convenient and affordable for the consumers. Accordingly, sales of music in compact disk formats have steadily declined. In this regards, online digital music has become a new communication channel to listen musics, where digital files can be delivered over various online networks to people's computing devices. The majority of online digital music distributors has Music Recommender Systems for sales of digital music on their websites. Music Recommender Systems are parts of information filtering systems that provide the ratings or preferences that users give to music. Korean online digital music distributors have Music Recommender Systems. But those online music distributors didn't provide any rules or clear procedures that recommend music. Therefore, we raise important questions as follows: "Is Music Recommender Systems Fair?", "What is the impact of Music Recommender Systems on online music rankings and sales?" While previous studies have focused on usefulness of Music Recommender Systems, this study investigates not only fairness of Current Music Recommender Systems but also Relationship between Music Recommender Systems and online Music Charts. This study examines these issues based on Bandwagon effect, ranking effect, Slot effect theories. For our empirical analysis, we selected the most famous five online digital music distributors in terms of market shares. We found that all recommended music is exposed to the top of 'daily music charts' in online digital music distributors' websites. We collected music ranking data and recommended music data from 'daily music chart' during a one month. The result shows that online music recommender systems are not fair, since they mainly recommend particular music that supported by a specific music production company. In addition, the recommended music are always exposed to the top of music ranking charts. We also find that recommended music usually appear at the top 20 ranking charts within one or two days. Also, the most music in the top 50 or 100 ranks are the recommended music. Moreover, recommended music usually remain the ranking charts more than one month while non-recommended music often disappear at the ranking charts within two week. Our study provides an important implication to online music industry. Because music recommender systems and music ranking charts are closely related, music distributors may improperly use their recommender systems to boost the sales of music that related to their own companies. Therefore, online digital music distributor must clearly announce the rules and procedures about music recommender systems for the better music industry.

Since the industry of music in Korea has been changed from phonographic industry to on-line music service, it is required increasingly that the rights and interests of music should been protected. Korea government has been announced the amendment for levy of music royalties through on-line service according to the changes in the music industry and industries' demand. In this paper, the corporate structures in music industry has been investigated from the point of owner of copyright, recently at the heart of the debate, flat rate system and usage-based pricing in on-line music market has been compared. Consequently, the reasonable prices of music service through on-line market are not earmarked in reality for both consumers and copyright proprietors. Therefore, it is still necessary to improve the institutional.

온라인 음원 스트리밍 서비스가 확대되면서 음원 사재기가 빈번해지고 있다. 본 논문에서는 사재기로 의심할 수 있는 음원의 특징을 분석하고, 사재기가 이루어지지 않았을 경우의 음원 순위를 예측한다. 그 결과, 랜덤 포레스트를 통해 앨범 평점이 낮은 음원, 장르가 인디나 발라드인 음원, 특정 발매사의 음원일 때 사재기로 의심할 수 있었다. 또한, 딥러닝을 통한 순위 예측 실험 결과, 사재기의 영향으로 실제 순위와 예측 순위에 큰 차이가 있는 것으로 나타났다.
