Question About how Audacity Dithers Exported Audio 2020-06-29 02:32:58 Hi everyone,First off, yes, I'm aware that Audacity has its own forums, but I can't register for the site because I never receive the authentication email.I would like to know exactly how to avoid exported audio from being dithered. Here is the Audacity wiki page explaining how their dithering works...https://manual.audacityteam.org/man/dither.htmlNow I recently edited audio I ripped from a CD (therefore 16 bit / 44100 Hz / Stereo) and encoded to FLAC Level 0 via Exact Audio Copy. I kept the settings the same as in that wiki article (therefore imported at 32 bit / 44100 Hz / Stereo). I edited the audio tracks in various ways...-Cut and Paste audio from one track to another-Deleting audio-Adding a fade out-Inserting a clip of silence-Creating a new Stereo track and pasting audio to it, deleting portions, then copying the audio back to the original imported track-Latency CorrectionI then export the track to 16 bit WAV format, to keep it lossless. However, according to this wiki article (If I'm understanding it correctly), because the audio is imported as 32 bit, rather than the 16 bit it actually is, it has to downscale the audio when exporting, therefore dithering it. I figured changing the Default Sample Format to 16 bit would prevent this because the article says this... Here's the exception to the rule: If you have recorded in 16-bit and are only doing simple editing (cut, delete, paste, trim...) and not doing any processing (amplify, equalize, frequency filter...) then for highest accuracy dither can be set to "none". In this case, because there are no 32-bit operations prior to export there is no benefit to using dither. Exporting a 16-bit track to 16-bit with dither set to "none" will be lossless. The same applies if exporting from a 24-bit track to an uncompressed 24-bit file format with dither disabled....but then the wiki article also mentions this...Downsampling also occurs when processing a 16-bit or 24-bit track because Audacity processes in 32-bit float format, which is then converted (downsampled) back to the 16 or 24-bit track format. Repeated downsampling can be avoided by working with 32-bit float format tracks (default), thus avoiding unnecessary conversion losses. Dithering is never applied within a 32-bit float project because no downsampling occurs.So I'm confused. I'm only working with 16 bit / 24 bit audio, so what exactly would I have to do to ensure whatever I export to 16 bit WAV remains entirely lossless, with the exception obviously of what I purposely edited?
