Therefore by default an imported file will show in the Track Control Panel as 32-bit float, even if its original bit depth is lower.
Generally, Audacity imports files at the sample format (bit depth) specified at Default Sample Format in Quality Preferences. However, once there is already an audio track in the project (either an imported file, a recording or generated audio), importing an audio file will not change the project rate.
There is no warning given that this rate change occurs.The Project Rate determines the sample rate a file will be exported at, so no further adjustment is needed to export that file at its original rate.to "open" an audio file), the Project Rate control in Audio Settings Preferences changes if necessary to reflect the rate of the file. When importing a file into an empty project window or when using File > Open.This does not “force” Audacity to use FFmpeg, but it tells Audacity to try FFmpeg first, and then you can look in the Audacity log ( ) to see what happened.Project Rate may change when importing initial audio file: You can use the “Format” dropdown to select “FFmpeg compatible files”. I don’t know how to force FFMPEG for import on 2.2.2 to test further. The current error message is certainly not helpful, and that is logged on the Audacity bug tracker. I suspect you’re right, though I’ve not seen any definitive information about this. Shouldn’t an FFMPEG error be shown instead then? I’m not an expert on macOS (I mostly use Linux), but my understanding is that the QuickTime Library was deprecated by Apple when they launched Sierra, and has been discontinued in xcode (the application for building software for macos). Since Quicktime does not support that file it should default to FFMPEG but that has a problem we get “This version of audacity was not compiled with Quicktime support” error. I deleted the whole audacity application support folder but that didn’t help.Įdit: I want to clarify that I don’t have any issues with FFMPEG export on either 2.3.0 nor with 2.2.2Įdit2: I am now suspecting broken AAC files - testing!Įdit3: Seems to be a FFMPEG 2.2.2 issue with ADTS.
Audacity 2.3.0 doesn’t import with FFMPEG, says Quicktime not supported. Ok it turns out I had 32bit FFMPEG 2.2.2 also installed. So the problem for me really was that Quicktime is not supported anymore in 2.3.0, is that correct? The 64-bit libraries are for the soon to be upcoming Audacity 2.3.1 which will be 64-bit, For Audacity 2.3.0 (and earlier) you need the 32-bit libraries which are lower down the download page.
