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 |

In March 2026, the DSS Chair attended the annual DAGA conference in Dresden. Thanks to the support of the GaS-Club, the student Aylin Kösker was given the opportunity to accompany the chair and participate in the conference from March 23rd to March 26th. As part of the daily poster sessions, she presented the results of her bachelor’s thesis “Machine Learning for the Analysis of Hydrographic Data to Assess the Waterside Accessibility of Port Waters” in the field of Underwater Acoustics. The thesis forms an important basis for an ongoing university research project on the acoustic analysis of sediment properties in harbor areas. The poster session enabled valuable discussions with researchers and conference participants from related research fields.
