To provide immersive 3D multimedia service, MPEG has launched MPEG-H, ISO/IEC 23008, “High Efficiency Coding and Media Delivery in Heterogeneous Environments.” As part of the audio, MPEG-H 3D Audio has been standardized based on a multichannel lo

This letter proposes a new masking threshold adjustment method to improve the quality for the speech signals in low bit-rate audio coding. The Enhanced aacPlus (EAAC) audio codec increases the masking threshold of all frequency bands to be suitable f

Pilot-based coding (PBC), which is used for lossless bit rate reduction of audio coding, has been recently proposed for MPEG Surround. We propose extended PBC for further lossless bit rate reduction of MPEG Surround. Extended PBC selects the number o

We propose novel techniques for the implementation of MPEG/audio (Layer II and Layer III) encoder. The proposed techniques concern implementing the encoder with a minimum complexity. As an effort to minimize the complexity, the ISO psychoacoustic mod

Unified Speech and Audio Coding (USAC) is an emerging MPEG audio standard striving for efficiently representing both speech and music signals even in very low bitrate ranges. The reference codec takes an approach of unifying two state-of-the-art spee

This paper proposes a unified speech/audio codec by adopting a single channel harmonic separation module as a pre-processor. A modulation frequency analysis method is used for harmonic separation, and the separated components are first encoded by an

Echo watermarking marks audio signals by adding an echo. The embedded signal is not additive noise but an audio signal having the same statistical and perceptual characteristics. The echo is even perceived as added resonance. Conventional echo waterm

This paper presents a high quality MPEG-1/2 layer-III decoding algorithm, which is optimized for a 16-bit fixed-point arithmetic. Motorola DSP56600 16-bit DSP family processor is chosen as a target processor, and quantization noise due to fixed-point

A new echo embedding technique in audio watermarking is proposed. The proposed method enables one to embed large energy echoes while the host audio quality is not deteriorated, so that it is robust to common signal processing modifications and resist
