Psychoacoustically-based processing of MPEG-I layer 1-2 encoded signals

چکیده
The MPEG audio standard has recently gained popularity for compressing high quality audio signals. In general, modifying or mixing MPEG signals requires decoding the MPEG signals into time-domain signals, processing the time-domain signals, and re-encoding the processed signals. In this paper, we present a psychoacoustically-based method for processing MPEG signals that eliminates signiicant portions of the encoding and decoding processes, resulting in reduced computational cost while maintaining perceptual audio quality.

Joint resolution enhancement and artifact reduction for MPEG-2 encoded digital video
A joint approach of resolution enhancement and artifact reduction for MPEG-2 encoded video is proposed in this paper. This new method uses a Unified Metric for Digital Video Processing (UMDVP). The UMDVP is defined based on coding information of MPEG-2 encoded video. It also takes the local scene content into account. Experimental results have demonstrated that the joint approach using the UMDV...
متن کاملA framework for end-to-end video quality prediction of MPEG video
This paper proposes, describes and evaluates a novel framework for video quality prediction of MPEG-based video services, considering the perceptual degradation that is introduced by the encoding process and the provision of the encoded signal over an error prone wireless or wire-line network. The concept of video quality prediction is considered in this work, according to which the encoding pa...
متن کاملLossless coding of MPEG-1 Layer III encoded audio streams
In this paper we describe a lossless coding scheme for the encoding of MPEG-1 Layer III encoded audio bitstreams. Commonly known as MP3, the MPEG-1 Layer III standard has proved widely popular for the transmission of encoded audio les (MP3's) over the Internet. However, the MPEG-1 Layer III standard has been designed with a wide range of applications in mind. As such, the frame sizes are kept s...
متن کاملSpeech Recognition on MPEG/Audio Encoded Files
A technique to peform speech recognition directly from audio files encoded using the MPEG/Audio coding standard is described. The technique works in the compressed domain and does not require the MPEG/Audio file to be decompressed. Only the encoded subband samples are extracted and processed for training and recognition. The underlying speech recognition engine used is based on the Hidden Marko...
متن کاملHigh Frequency Reconstruction for Band-limited Audio Signals
Current existing digital audio signals are always restricted by sampling rates and bandwidth fit for the various storages and communication bandwidth. Take for example the widely spread mp3 tracks encoded by the standard MPEG1 layer 3. The audio bandwidth in MP3 is restricted to 16 kHz due to the protocols constraints defined. This paper presents the method to reconstruct the lost high frequenc...
