Bitrate Detection for the AMR-WB Codec

The following speech samples are provided to illustrate speech coding effects of the AMR-WB codec at different bitrates.  For the single coded examples, the original speech signal was simply coded and decoded at the specified bitrate. For the tandem coded examples, the single coded signals were subject to a consecutive stage of coding and decoding.

 

Examples - Single coded

Bitrate   Male   Female
         
Original    
         
6.60 kbit/s    
         
12.65 kbit/s    
         
23.85 kbit/s    

 

Examples - Tandem coded

Bitrate   Male   Female
         
Original

DSS-Retreat 2019

As in the last year we spent a couple of days (15.10.2019 till 18.10.2019) on the island Sylt to reflect our past, current, and future research work. Due to a "cold wave" we were a bit reduced this year, but anyhow, we had a very good (and producive) time on this beautiful island. Beside our research plans (reflecting the last year and planning of the next years), we also discussed teaching ...
