I recently got 13 FLAC-Files from SoundCloud, with a track-length between 2:51 and 10:54, between 7.84 MB and 68.2 MB. If I look in "Audio" and search for ".flac", I can compare my 13 files, their bitrate is between 297 kbps and 949 kbps, but the bitrate is independent from the track length. 2 files have a year, a genre and an album (a 3rd file has also an album), although I cannot write tags into a flac-file. All the files have an artist and a title, no one file has an embedded album art.
I have no one APE-File, but less OGG and WMA, very much MP3 (I myself prefer 320 kbps, but I have also got many other bitrates as downloads, some as CBR and some as VBR) and also many WAV (sound-samples and own tracks, also some downloaded tracks). My WAV-Files, which were ripped with Goldwave, have 1441 kbps. Okay, WAV-Files eat many space, but they have a very good sound, if I use our headphones (we have some Beyerdynamic DT 990). I had exported 16 demosongs of MAGIX Music Maker 17 Premium and MAGIX Samplitude Music Studio 17 as WAV-Files, with 48000 Hz instead of 44100 Hz, of course, and their bitrate is between 1536 kbps and 1547 kbps (I have looked now). They had sounded very good, when they were played immediately after their export.
WAV-Files can also be sorted, each album in the subfolder of the artist (the subfolder is named as artist - album), each track is named by artist - track there, and each subfolder contains also the JPG-File "cover".
I have not yet many experiences with FLAC-Files, but yesterday I have listened to a WAV-File again with the Beyerdynamic DT 990, and I can only say, nothing can beat WAV...
