Method and apparatus for encoding digital signals employing bit allocation using combinations of different threshold models to achieve desired bit rates
uspto.gov
google patent search
A method for encoding a digitized audio signal which includes the step of selecting one of two or more psycho acoustic model provided for generating masking thresholds used in a data reduction process. The selecting criterion is the available data rate for the encoded bit stream. Each one of the two or more psycho acoustic models is adapted to a specific data rate of the encoded bit stream. In a second embodiment, the method includes the step of combining two or more masking thresholds resulting from different psycho acoustic models, thereby leading to a more accurate calculation of a masking threshold for the data reduction process. Further, there are appropriate apparatuses for the encoding of digitized audio signals.
US Patent #: 6,009,399
Application #: 08/838,297
Filed: April 16, 1997
Granted: December 28, 1999
Expires: April 16, 2017

Could someone please translate all of this techno-talk into understandable English? Preferably in 1-syllable words (like Run Spot Run. See Spot Run...).

Sure, Anyone will be able to convert their wave files to MP3 files with any converter they choose now.

Quote:
On April 23, 2017, Technicolor's mp3 licensing program for certain mp3 related patents and software of Technicolor and Fraunhofer IIS has been terminated.

The development of mp3 started in the late 80s at Fraunhofer IIS, based on previous development results at the University Erlangen-Nuremberg. Although there are more efficient audio codecs with advanced features available today, mp3 is still very popular amongst consumers. However, most state-of-the-art media services such as streaming or TV and radio broadcasting use modern ISO-MPEG codecs such as the AAC family or in the future MPEG-H. Those can deliver more features and a higher audio quality at much lower bitrates compared to mp3.


Quote:
However, the end of the mp3 licensing program does not automatically mean that all mp3 technology is available license-free now. Apart from the core mp3 patents included in the licensing program, there might still be some implementation–specific patents (or patents for other functional enhancements) that have not expired. Thus, manufacturers will have to check the situation regarding their intended products first before including mp3.

I personally believe this to be great news for Karaoke enthusiasts.
