Pick a song that you know
really well, something that’s in your bones like Siberian
Khatru. Grab it from CD using cdparanoia to have it as
a WAV file. Now open your favourite wave editor and slice the file
up into multiple consecutive sections. Be careful not to insert
silence, delete samples or alter any sample data. Save the slices to
separate files. Now convert the sample rate of some pieces to random
values (the example program shipped with the libsamplerate library will
let you do this in very good quality). Pick some pieces and convert
them to Ogg Vorbis
format. Pick some others and encode them to FLAC. Pick a few and convert
them to MONO. Now open up the Playlist editor of the music player in
question and add the files in order. Push play, and
listen.

Aqualung is a music player designed from the ground up to
provide continuous, absolutely transparent, gap-free playback across
a variety of input formats and a wide range of sample rates thereby
allowing for enjoying quality music: concert recordings and
“non-best-of” albums containing gapless transitions between some
tracks. (Multiple movements long compositions are often broken into
separate but gaplessly flowing tracks when mastered to CD.) Obvious
examples are The Song Remains The Same (Led Zeppelin), The
Dark Side Of The Moon (Pink Floyd), and Yessongs
(Yes). Besides the ability to play the music from these records
without a defect, Aqualung provides high quality sample rate
conversion, a feature that is essential w
