Using foobar2000 0.8.2, W2K+SP4.
I have many small wavs (3-4 seconds) and foobar displays double duration for them, which makes the seekbar go only until the half of its total size.
This is the report for one wav (foobar says duration 0:07.479):

bitrate = 88
samplerate = 44100
channels = 1
codec = Microsoft ADPCM
bitspersample = 4
decoded_bitspersample = 16
----------
329831 samples @ 44100Hz
File size: 83 044 bytes

If I use diskwriter to convert it to PCM, foobar reports duration 0:03.739 and:

bitrate = 705
samplerate = 44100
channels = 1
codec = PCM
bitspersample = 16
----------
164916 samples @ 44100Hz
File size: 329 876 bytes

The funny thing is that even Windows onw Sound Recorder reports it with double duration and the displayed duration skips faster in order to finish at 7 seconds, while the track is only 3.5 seconds blink.gif
