16-bit files that are edited at 32-bit—Is it OK to reduce to 16 again? 2009-06-02 11:43:32 I am not very experienced in audio processing theory but I would like to learn more about it. So please help me.The situationSeveral years ago hard drives have been expensive and their capacity was limited compared with nowadays. So I made the mistake of compressing recordings (44.100 Hz, 16-bit) of my own compositions into a lossy format (mp3, 320 kBit/s CBR; I don't know whether flac or Wavepack have already exist at that time).In the meantime I have edited some of those files in Audacity (which internally uses 32 bit as far as I know) and saved this edited files as "WAV Microsoft 32 bit float" for further editing.My questionIn advance some of the edited tracks I have to send to a studio in a lossless format (as test recording only, no editing there) and by no means I want to risk a loss of audio quality once more.For transmitting to the studio can I nevertheless reduce the 32-bit files to 16-bit (because the source files have not been better) or should I use 32-bit (because Audacity uses it)?English is not my mother tongue but I hope you will understand my concern, it is very important for me. I would appreciate any suggestions.Robertina.
