LCODCCMW3.DLL LCMW3.DLL DSKernel2.DLL

The LEAD MCMW codec is a wavelet compressor/decompressor that registers into the Windows® collection of multimedia drivers and integrates with any application using DirectShow. It uses proprietary wavelet compression to compress images hundreds of times smaller than uncompressed images without producing compression artifacts that can be found in MJPEG compression. Wavelet compression translates to higher quality video with smaller files sizes.

LCODCCMP2.DLL

 DSKernel2.DLL

The LEAD MCMP/MJPEG codec offers the power to compress TV quality video at 30 frames per second in real-time. Additionally, because the codec includes MJPEG and MCMP, the codec adds the flexibility of using standard or proprietary encoding. The LEAD MCMP/MJPEG codec integrates with any application using DirectShow or Video for Windows.

LCODCJ2K2.DLL LMJ2K2.DLL DSKernel2.DLL

The LEAD JPEG2000 Video codec saves standard JPEG2000 streams. This codec is particularly useful when high compression and interoperability are necessary. JPEG2000 provides high compression with image quality superior to all existing standard encoding techniques. This high compression and quality performance is due to the adaptation of wavelet transforms.

LMAMpgCnv.DLL DSKernel2.DLL

The LEAD MPEG Audio Converter is a helper filter that is used automatically to convert audio subtype from MEDIASUBTYPE_MPEG2_AUDIO to MEDIASUBTYPE_MPEG1AudioPayload to help play the audio in MPEG2 files created with "LEAD MPEG Audio Encoder" in case a DVD audio decoder is not installed. So basically this filter converts MPEG2 audio type to MPEG1.

AC3 is the sound format for digital television (DTV), digital versatile discs (DVDs), high definition television (HDTV), and digital cable and satellite transmissions. AC3 is a 5.1 format, which means that it provides five full-bandwidth channels, front left, front right, center, surround left, and surround right. A low-frequency effect (LFE) channel is included for the sound needed for special effects and action sequences in movies. AC3 also has a downmixing feature that ensures compatibility with devices that do not support the 5.1 format.

LDecAC3.DLL, DSKernel2.DLL

The LEAD AC3 Decoder, is a DirectShow filter for decompressing audio data. AC3 audio compression is used mainly in DVDs with 5.1 channels surround sound.

LEncVorbis.DLL

LDecVorbis.DLL

The LEAD Vorbis-based Audio Codec, is a DirectShowÒ filter for compressing and decompressing audio data using the Vorbis compression algorithm. Vorbis is a new audio compression method used to store digital music or any audio data. The compressed audio data can be stored inside AVI or Ogg files. Compared to MP3 compressed audio files, Vorbis based compression produces audio files that maintain a higher sound quality and/or a smaller compressed size, depending on the needs of the user. For example, the user has the option of keeping their digital music collection at the same sound quality level as MP3, but requiring significantly less disk space. Or, a user can commit the same amount of storage (disk space) as their MP3 based files, however their digital music will have higher quality sound.

LEncMpgA.DLL

The LEAD MPEG Audio Encoder is a DirectShowÒ filter for compressing Audio data using the MPEG-1 Layer 2 audio compression standard (ISO/IEC 11172-3). This audio format can be multiplexed into an MPEG-1 or MPEG-2 file. Use this audio codec when you create MPEG-1 or MPEG-2 files.

MPEG-1 Layer 3 compression offers higher audio compression than MPEG-1 Layer 2, but this audio compression is not supported by most MPEG splitters.
