EXPORT AUDIO AUDACITY MAC
AIFF (Apple/SGI) signed 16-bit PCM No options for this format: AIFF is a lossless format that can both be played on Mac and Windows computers, though it is far more likely to be selected by Mac users.This menu item defaults to WAV (Microsoft) signed 16-bit PCM on Windows and Linux and to AIFF (Apple/SGI) signed 16-bit PCM on Mac. Also GSM 6.10 WAV (mobile) which produces a mono WAV file encoded with the compressed, lossy GSM 6.10 codec as used in mobile telephones. Other uncompressed files: includes all the uncompressed audio formats that Audacity can export, including 4-bit (A)DPCM, 8-bit U-Law/A-Law, 24-bit, 32-bit and 64-bit options.GSM 6.10 WAV (mobile) will also exhibit considerable loss of quality as it was a format designed for mobile telephony. Those 4-bit formats and the lossless 8-bit U-Law/A-Law formats save file size by reducing their bit depth, in a similar way that any of the uncompressed formats can be made proportionately smaller by reducing their sample rate (and thus reducing the high frequencies they can contain). There is no loss of quality compared to the original audio when playing uncompressed formats, except for some possible loss of low frequencies in the 4-bit (A)DPCM formats. The most common uncompressed formats are WAV and AIFF.
So I'm confused.The following are all uncompressed audio formats in which every sample of sound is represented by a binary number. Dithering is never applied within a 32-bit float project because no downsampling occurs. Repeated downsampling can be avoided by working with 32-bit float format tracks (default), thus avoiding unnecessary conversion losses. but then the wiki article also mentions this.ĭownsampling 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. The same applies if exporting from a 24-bit track to an uncompressed 24-bit file format with dither disabled. Exporting a 16-bit track to 16-bit with dither set to "none" will be lossless. In this case, because there are no 32-bit operations prior to export there is no benefit to using dither. 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". I figured changing the Default Sample Format to 16 bit would prevent this because the article says this. 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 then export the track to 16 bit WAV format, to keep it lossless. Creating a new Stereo track and pasting audio to it, deleting portions, then copying the audio back to the original imported track Cut and Paste audio from one track to another I edited the audio tracks in various ways.
EXPORT AUDIO AUDACITY 32 BIT
I kept the settings the same as in that wiki article (therefore imported at 32 bit / 44100 Hz / Stereo). Now 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. Here is the Audacity wiki page explaining how their dithering works.
EXPORT AUDIO AUDACITY HOW TO
I would like to know exactly how to avoid exported audio from being dithered. 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.
