Test a corpus of 585 public domain FLAC files with a duration of less than 1 minute from freesound.org.
Out of these files, the following increased code coverage and where thus added to the test suit.
* 19875 (sample rate 48 kHz)
* 44127 (8 bits-per-sample, sample rate 22254)
* 80574 (sample rate 22050)
* 191885 (block size 1, verbatim)
* 212768 (sample rate 88200)
* 220014 (utf-8 continuation byte)
* 243749 (sample rate 8000)
* 257344 (sample rate 32000)
* 256529 (sample rate 192000)
