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)
