gepa21 / flacbox Goto Github PK

Hi,

I am working on a program for analyzing sound level, dynamics and clipping in any music library. For this I am using the FlacBox code.

However, I receive a few types of FlacExceptions when reading certain flac files:

The files were ripped using a recent version of dbPoweramp (15.2.0.3), and I ran over 10000 files, and around 50 failed with the following errors.

Exception:FlacBox.FlacException: Invalid subframe coefficient precision
Exception:FlacBox.FlacException: Subframe type is set to reserved=17
Exception:FlacBox.FlacException: Subframe type is set to reserved=18
Exception:FlacBox.FlacException: Subframe type is set to reserved=4
Exception:FlacBox.FlacException: Unexpected end of stream: bit reader needs data
Exception:FlacBox.FlacException: Zeros expected for alignment padding

I have tried re-ripping most of the files in dbPoweramp, but the results are the same afterwards.

I am currently trying to find out if this is due to a dbPoweramp problem or if it is a problem in FlacBox.

Please help me in pinpointing it!

Regards, Kenneth
