A possible new more visual and less wordy way to do the click hint...
  • Peter 27Nov17: The informal user observation research with my "mystery shopper" revealed that it was the abundance of information in the hovertext tips that threw her. She thought that that was all there was and didn't think about clicking to driil-down for more.

Dropdown menu for selecting the required file formatAIFF 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. AIFF 16-bit PCM is suitable whenever you want to burn your exported file to an audio CD. There are no options for this format.WAV is a lossless format that can both be played on Windows or Mac computers. WAV 16-bit PCM is eminently suitable whenever you want to burn your exported file to an audio CD. There are no options for this format.32-bit float WAV is a lossless format, a maximum quality "raw capture" file. 32-bit float resolution gives the highest quality of the three uncompressed choices, but takes twice the storage space on disk compared to 16-bit resolution. It will not play on many players or player apps. It is mostly useful as a backup archive of raw captured recordings or finished projects. There are no options for this format.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. 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. 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.MP3 is a popular compressed, lossy format producing much smaller files than WAV or AIFF, at the expense of some loss of quality. You must download the optional LAME encoder to export to MP3.Ogg Vorbis is the compressed, lossy Vorbis codec in an OGG container. Vorbis offers higher quality than MP3 for the same file size, and is useful for good quality small-sized mono files, but fewer applications can play the OGG format.FLAC is a compressed but lossless format, giving much larger file sizes than MP3 and OGG but only about half the size of WAV.MP2 is a compressed, lossy format similar to MP3, producing slightly larger files than MP3 for the same quality.(external program) sends audio via the command-line to any executable binary application either for processing or for encoding as a file. This is a method to export using an alternative compressed or uncompressed encoder or to a format not otherwise supported by Audacity.AAC: Advanced Audio Coding is a compressed, lossy format used in Apple applications, generally achieving slightly better quality than MP3 for the same file size. By default, the exported file will be given an "m4a" extension. Optional permitted extensions: .mp4, .m4r (ringtone) and .3gp (mobile).AC3 is the common name used for the compressed, lossy format used in Dolby Digital.AMR: Adaptive Multi-Rate codec is a patented compression scheme optimized for speech, but also used for mobile telephone ringtones. The wide band variant uses higher bandwidth for higher quality.WMA: Windows Media Audio v2 is a compressed, lossy format developed by Microsoft. Optional permitted extensions: .asf or .wmv.Custom FFmpeg Export allows interface-based export of some additional compressed or uncompressed formats not listed above, and options for exporting formats containing alternative codecs (for example, WAV format containing MP3 or OGG format containing FLAC). Note: not all formats and codecs are compatible, and some exports might result in zero-byte or invalid files if FFmpeg does not support the combination chosen.File types for Export W10.png

Format Options

Notice with the image at the top of this page, for the default export to WAV format there are no export options. However some formats do offer options for making settings like quality or encoding.
