Modified SAOC Scheme Using Harmonic Information for KARAOKE Application
نویسنده
چکیده
An interactive audio service provides audio editing functionality to users. In the service, users can control the desired audio objects to make their own audio sound using a spatial audio object coding (SAOC) scheme. However, vocal objects cannot be removed perfectly from the down-mix signal in Karaoke applications of the SAOC. Thus, in this paper, a modified SAOC scheme with harmonic extraction and elimination structures are proposed. The proposed scheme removes vocal objects using their harmonic information. In addition, statistical modeling method is applied to reduce bit rates of the information. Subjective and objective evaluation results show the proposed scheme is superior to the conventional ones which are the normal SAOC and the nonnegative matrix factorization (NMF) algorithms. Index Terms — Spatial audio object coding, harmonic elimination, KARAOKE mode, vocal removal.

متن کاملModified Sliding-Mode Control Method for Synchronization a Class of Chaotic Fractional-Order Systems with Application in Encryption
In this study, we propose a secure communication scheme based on the synchronization of two identical fractional-order chaotic systems. The fractional-order derivative is in Caputo sense, and for synchronization, we use a robust sliding-mode control scheme. The designed sliding surface is taken simply due to using special technic for fractional-order systems. Also, unlike most manuscripts, the ...
متن کاملGravity acceleration at the sea surface derived from satellite altimetry data using harmonic splines
Gravity acceleration data have grand pursuit for marine applications. Due to environmental effects, marine gravity observations always hold a high noise level. In this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. On the one hand, harmonic spline functions have great capability for local gravity ...
متن کاملA Modified Phase-Shifted Pulse Width Modulation to Extend Linear Operation of Hybrid Modular Multi-level Converter
Recently, hybrid modular multi-level converters, which are configured as full and half bridge sub-modules, are developed and utilized in the wide area of applications. Compared to its non-hybrid counterpart, these converters have several advantages such as the ability to nullify the DC side fault current and controlling AC side reactive power during the faults. This paper proposes a modified ph...
متن کاملTriangular Intuitionistic Fuzzy Triple Bonferroni Harmonic Mean Operators and Application to Multi-attribute Group Decision Making
As an special intuitionistic fuzzy set defined on the real number set, triangular intuitionistic fuzzy number (TIFN) is a fundamental tool for quantifying an ill-known quantity. In order to model the decision maker's overall preference with mandatory requirements, it is necessary to develop some Bonferroni harmonic mean operators for TIFNs which can be used to effectively intergrate the informa...
