title: wav file limited to 35 minutes in length?
body: <p>I recorded 13 hours of audio to a wav file (48kHz sampling rate) with the Android App "AudioRec". The file is ~4,2G in size. 
  I then transfered the file to my gentoo linux and tried to open it with ffmpeg, vlc, mpv and audacity, sox. In all applications the file has a length of exactly 35 minutes.</p>
  
  <p>If I open the file in audacity with Import->Rawdata it indeed reads the whole file as 13 hours sound file. But if I export the file again with same format settings (48kHz,mono,pcm_s16le) to wav still no application is able to read it with 13 hours lenght... So I guess I have to split the file in 34:59 minutes chunks to use them (my intention was to feed the 13 hours to sox to create a spectrogram)...</p>
  
  <p>Is there anyone who has an explanation why there is this 35 minutes restriction?</p>
