The main improvements in this version are as follows:

1. Optimized the playback algorithm to fix the issue in the previous version where playback was easily affected by other software, leading to increased latency and audio glitches.

2. Added a progress bar to the playback feature, showing the current position and allowing users to adjust the playback progress in real time.

3. Added user control interface for the recording feature. Users can now set the location of recorded files and specify the maximum recording time.

4. Added a latency setting in the parameter configuration section. A 4ms latency can be used with the B series 6207 and newer versions.
