Unfortunately one of my portable recorders sometimes creates WMA (version 8) audio files with "birdy-sounds".
By "birdy-sounds" I mean a continuous restless low-level artifact which can be heard in the background of the recording.
Would different WMA decoders manage to replay the same audio file with fewer "birdy-sounds" than other WMA decoders?
I would expect one compliant decoder to return exactly the same file (within rounding errors) as another compliant decoder.
