چکیده
■ Figure 1 Audio Technology for the Network Age Last year Sony released the Memory Stick Walkman, which uses the Memory Stick as its recording media. The Memory Stick Walkman adopts the ATRAC3 (Adaptive Transform Acoustic Coding 3) high-quality audio encoding technology and achieves high-quality audio reproduction equivalent to that of MD players. ATRAC3 is a further development of the ATRAC technology adopted by the MiniDisc (MD), which was released in 1992. ATRAC3 can be effective not only in packaged media applications such as MD and Memory Stick, but also in networked environments such as music distribution services. This article presents the ATRAC3 highquality audio encoding technology and LSIs that include that technology. ATRAC3 Features

Design of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...

In the recent decades, rapid population growth has led to the significant increase in food demand. Food supply chain has always been one of the most important and challenging management issues. Product with short age, especially foodstuffs, is the most problematic challenges for supply chain management. These challenges are mainly due to the diversity in the number of these goods, the special n...
متن کاملCombining pattern recognition and deep-learning-based algorithms to automatically detect commercial quadcopters using audio signals (Research Article)
Commercial quadcopters with many private, commercial, and public sector applications are a rapidly advancing technology. Currently, there is no guarantee to facilitate the safe operation of these devices in the community. Three different automatic commercial quadcopters identification methods are presented in this paper. Among these three techniques, two are based on deep neural networks in whi...

Background: Catheterization is the most common cause of pain and distress in children, which causes physical and psychological dysfunctions and disrupts the treatment. Therefore, the control of this type of pain should be considered as a priority for nursing care. The audio-visual distraction can be used to reduce the intensity of pain. Aim: The purpose o...
متن کاملAnalysis of Packet Loss and Latency Control for Robust IPTV over Mobile WiMAX and LTE Assessment (RESEARCH NOTE)
Abstract The streamed audio video (AV) content for IPTV across mobile WiMAX channel, the different schemes were discussed to reduce the noise, packet loss and latency. The objective of this paper is to verify the effectiveness of forward error correction (FEC) techniques and to suggest the techniques for robustness problems and to analysis the issues either due to AV coding encoding or due to...
