Default WAV 24-bit extension is .AIFF

Permanent link to this post Posted by ppw1 » Tue Nov 21, 2017 12:08 pm

In the more recent versions of Audacity,

when exporting audio to "Other uncompressed files" -> Header: "WAV (Microsoft)", Encoding: "Signed 24-bit PCM", the file extension gets set to .AIFF when it should be .WAV. (It was .WAV in the previous versions. All encoding types under the header WAV (Microsoft) have the extension .AIFF.) I don't know if this is deliberate or not, but

WAV (Microsoft) signed 16-bit PCM has a .WAV file extension.
WAV (Microsoft) 32-bit float PCM has a .WAV file extension.

It's only right for the 24-bit format to have a .WAV extension as well.

For Audacity 2.2.0, the opposite seems to be the case: .WAV is set as the default extension for all other uncompressed files, including AIFF, AU, WAVEX, W64 .. each of which has their own file extension ...

That looks to be the case when I test on W10 on 2.2.0 (and on 2.2.1 alpha). No account seems to be taken of what the user selects in the Format Options>Header dropdown menu on the Save as type>Other uncompressed files dialog - I would expect to in ideal circumstances.

And today it rang an even louder bell as I tested on Windows 10 and macOS High Sierra.

It appears to be a general bug affecting all platforms whereby:
The underlying problem would appear to be the when using "Other uncompressed files" as the "Save as type" in the Export dialog when the user goes to the "Format Options" part of the dialog and chooses something other then the default or last-used in the "Header" dropdown - Audacity does not update the file extension in the "File name" data box.

Pressing the OK button will however cause Audacity to export the file in the required format and with the correct extension that the user specified in the "Header" dropdown.

A subsequent visit to The Export Audio dialog will show that Audacity remembers the "Header" type correctly AND it sets the extension in the "File name" correctly. BUT changing the "Header" type to something else shows that then the "File name" extension is once again not visually changed.


Accordingly I updated the bug report extending it to all platforms and updated the steps to reproduce and the release note for this bug.

I also upgraded it from P3 to P2 (Priority level 2).

Full bug report here: http://bugzilla.audacityteam.org/show_bug.cgi?id=1355

Many thanks for (re)alerting us to this ppw1 8-)
