parametric stereo造句
例句與造句
- The SBR and parametric stereo ( introduced with HE-AAC v2 ) is ignored.
- The technology is similar to parametric stereo, in which a mono signal is recovered to stereo.
- HE-AAC version 2 profile ( HE-AAC v2 ) couples SBR with Parametric Stereo ( PS ) to enhance the compression efficiency of stereo signals.
- The Parametric Stereo audio object type used in HE-AAC v2 was first defined in ISO / IEC 14496-3 : 2001 / Amd 2 : 2004.
- Prior to the standardization of HE AAC v2 by MPEG, Coding Technologies submitted the combination of HE-AAC v1 coupled with Parametric Stereo under the name Enhanced AAC +.
- It's difficult to find parametric stereo in a sentence. 用parametric stereo造句挺難的
- Brazilian system is based on MPEG-4 HE-AAC v2, that is it includes de SBR ( spectral band replication ) and PS ( parametric stereo ) tools.
- The HE-AAC v2 Profile ( AAC LC with SBR and Parametric Stereo ) was first specified in ISO / IEC 14496-3 : 2005 / Amd 2 : 2006.
- By having the Parametric Stereo side info along with the mono audio stream, the decoder ( player ) can regenerate a faithful spatial approximation of the original stereo panorama at very low bitrates.
- Because only one audio channel is transmitted, along with the parametric side info, a 24 kbit / s coded audio signal with Parametric Stereo will be substantially improved in quality, compared to a discretely stereo coded audio signal coded with conventional means.
- An AAC HE v2 bitstream is obtained by downmixing the stereo audio to mono at the encoder along with 2-3 kbit / s of side info ( the Parametric Stereo information ) in order to describe the spatial intensity stereo generation and ambience regeneration at the decoder.
- Adjustable settings for each encoder include bitrate ( for MP3, AAC +, Ogg Vorbis ), quality ( for AAC, Ogg Vorbis ), sample rate ( 22050 Hz or 44100 Hz ) and channels ( Parametric Stereo is available for AAC + up till 56kbps ).
- It is based on the AAC LC, SBR and Parametric Stereo coding tools defined in the MPEG-4 Audio standard ( and it refers to ISO / IEC 14496-3 : 2001 / Amd . 1 : 2003-Bandwidth Extension, ISO / IEC 14496-3 : 2001 / Amd . 2 : 2004-Parametric Coding for High Quality Audio, ISO / IEC 14496-3 : 2001 and ISO / IEC 14496-3 : 2001 / Amd . 1 : 2003 / DCOR1 ).
