The conversion from 16 or 24-bit integer to floating-point and back is lossless. If I understand correctly, this is not lossless anymore, right? So it means when I export the WAV (Audacity mixes it as a mono before exporting), is it still lossless? Do I need to dither even if I export to the same bit depth?Īudacity normally works internally at 32-bit floating-point. I use “Split Stereo to Mono”, then I select and invert this channel - now, when I play both channels together, the end result is that this technique reduces the overall level of the reverb of the left channel due to phase cancellation (that’s what I want). Let’s say that the right channel has reverb only.

If I use “Split Stereo to Mono” and then export only mono left or mono right channel (I delete the channel I don’t need) without doing anything to it - is the exported file still lossless? Because the Repair tool will be altering the audio file, I need to apply dither, even when I’m not changing the bit depth, correct? Is Repair tool “destructive”? Meaning that there will be some quality loss? If it is, then I’m fine with that because I would use it to remove unwanted cracks and pops on my vinyl rips. When exporting them, to the exact same bit depth, do I need to dither because Audacity is in 32-bit and the files are in lower bit depth? Should I change the Audacity settings to either 16-bit or 24-bit respectively before importing those files? I’m not doing anything else than cutting, copying, deleting, pasting, trimming to these audio files. Let’s say I have two files, 1st one is 16-bit, 2nd one is 24-bit. 44.1 khZ / 24-bit) as the original file, and the end result will be lossless, correct? Do I need to apply dither in this case?īy default, Audacity uses 32-bit float bit depth. I would also like to clean some songs (mainly the vinyl ones).Īs I understand, if I import a WAV/FLAC of a song and only use cut, copy, delete, paste, trim, and do nothing else (no volume changes, no FX), I can safely export the file to the exact same sample rate and bit depth (e.g. I want to edit these audio files in a lossless way - cut out and move around only the parts of the songs that I like, then export them as WAV. So the situation is that I have a lot of ripped CDs and vinyl records in various formats: most of them are 44.1 khZ / 24-bit, but there are also a lot of files in 16-bit, either FLAC or WAV.
