When a Chain includes a command to export it places the new audio file (currently there is no Chain command to save a Project) in a folder called (for historic reasons) "cleaned" which will be located in either: 1) If applying to the current Project, the folder to which the user most recently exported (or, possibly, saved a Project); or 2) If applying to file(s), the folder in which the file(s) reside, and adds that newly created file to the recent history list.
When there has been no import and a Chain is applied to the current Project Audacity creates a file name built out of the date and time: yyyy-Month-dd-hh-mm-ss.ext.
Chains include two types of commands - recognized effects and a small handful of "special commands":
"ExportMP3_56k_before", "ExportMP3_56k_after", "StereoToMono", "ExportFLAC", "ExportMP3", "ExportOgg", "ExportWAV" all of which, with the exception of StereoToMono (which is actually a built-in effect masquerading as a menu item), are built-in exporters.
SUGGESTIONS
1) For all the export-type special commands, instead of placing the new audio in the "cleaned" folder, put the old audio (when there has been an import) in that folder (which I would suggest renaming "remnants" or some such as the "cleaned" designation relates to the now-defunct Clean Speech and it would make an obvious distinction) and placing the new audio file in the folder from which the import came.
existing code:
Code: Select all
else if (command == wxT("ExportWav")) {
filename.Replace(wxT(".mp3"), wxT(".wav"), false);
double endTime = GetEndTime();
if (endTime <= 0.0f) {
return false;
}
return mExporter.Process(project, numChannels, wxT("WAV"), filename, false, 0.0, endTime);
}Code: Select all
else if (command == wxT("ExportWav")) {
filename.Replace(wxT(".mp3"), wxT(".wav"), false);
double endTime = GetEndTime();
if (endTime <= 0.0f) {
return false;
}
//efm5 start
bool exportedOkay = mExporter.Process(project, numChannels, wxT("WAV"), filename, false, 0.0, endTime);
if (exportedOkay) {
wxString temporaryStub(wxT(".TEMPORARYNEWFILE"));
wxString paddedNewFilename(filename);
paddedNewFilename.Append(temporaryStub);
::wxRenameFile(filename, paddedNewFilename);
wxFileName oldFile(project->GetImportFileName());
oldFile.AppendDir(chainFolder);
wxString oldFilesNewName(oldFile.GetFullPath());
::wxRenameFile(project->GetImportFileName(), oldFilesNewName);
wxString newFileName(paddedNewFilename);
wxString folderRemoval(wxFileName::GetPathSeparator());
folderRemoval.Append(chainFolder);
newFileName.Replace(folderRemoval, wxEmptyString);
newFileName.Replace(temporaryStub, wxEmptyString);
::wxRenameFile(paddedNewFilename, newFileName);
}
//wxGetApp().AddFileToHistory(filename);
project->SetJustExported(true);
return exportedOkay;
//efm5 end
}**The proposed new code should include re-factoring all of the exporters because there is a lot of duplicated code. I just added my new code to one of them (because it is the only one I use) as a proof-of-concept.
2) When there has been no import, instead of building the file name from the date and time, immediately ask the user for a file name string as the first part of the batch process (with suitable error checking) - that way the user may go out for a suitable beverage during long batch processing sessions.
