How to save and reopen an editable TLSound project

You have edited an audio project and want to keep working on it later, or move it to another device. The key is to save the editable project, not just export a finished audio file.

The Audio Editor can open audio files, edit clips on tracks, and export WAV or MP3. Follow these steps to keep a TLSound project you can reopen and continue editing.

Save and reopen a TLSound project

1. Open the Audio Editor and load the audio files you want to use. Make your edits, such as trimming a clip, adding a fade, changing speed or pitch, or arranging clips on tracks.
2. When you are ready to keep an editable copy, use the editor's project-saving or project-download option. Save the project in TLSound format, rather than exporting only a WAV or MP3.
3. Choose a folder you can find again, such as Downloads or a dedicated project folder. If your browser asks where to save the file, choose a location and keep the file's .tlsound extension.
4. To continue later, open the Audio Editor and use its project-opening option to select the saved .tlsound file. Check the timeline and play a few sections to make sure the project opens as expected.

On Windows 11, look in File Explorer › Downloads if you saved the project to the default download folder. On macOS, check Finder › Downloads. If you chose a different folder, browse to that location in the file picker.

What the result means

The timeline and separate clips are back

The editable project reopened. You can continue adjusting cuts, fades, speed, pitch, and track arrangement, then save the project again when you are done. Keep a separate copy if you want a backup before making major changes.

You see one finished audio file

You probably opened a WAV or MP3 export rather than the TLSound project. An exported audio file is meant for listening or sharing. It usually contains the combined sound, not the separate clips and editing decisions. Find the file ending in .tlsound and open that instead.

The project file is missing

The browser may have saved it to another folder, or the download may not have completed. Check the browser's download list and the Downloads folder. Search your computer for .tlsound if you still cannot find it.

The project opens but asks for audio files

If the editor requests source audio, locate the original files you used and select them. Keep those files available with the project until you have confirmed that it reopens successfully. A project file and its source audio may be separate items, depending on how the project was saved.

How to fix it

1. Make sure you saved a project. Use the project-saving option, not the audio export option. WAV and MP3 are useful finished formats, but they are not substitutes for an editable TLSound project.
2. Check that the download finished. Look in your browser's download list for a completed file. If the download failed, save the project again and wait for the browser to finish before closing the tab.
3. Keep the file extension. The project should end in .tlsound. Do not change the extension to .wav or .mp3, because renaming a file does not convert its contents.
4. Open the project from inside the editor. Start the Audio Editor, then use its project-opening option and select the TLSound file. If you double-click the file and it opens as text or does nothing, return to the editor and choose it from the file picker.
5. Try the original source files again. If the project asks for media, choose the audio files that were used when it was created. Avoid moving or deleting them until the project is fully restored.
6. Save a fresh copy. If the project opens but seems incomplete, use the editor's project-saving action again and choose a new filename. Reopen that copy to check it before removing the earlier file.

If the browser does not let you choose a download location, check its download settings and make sure downloads are allowed for the page. If a local export appears to do nothing, see Local file export does nothing? What to check.

Project file or finished audio?

Keep both kinds of file when you need to edit and share the result. The .tlsound project is the working copy for returning to the timeline. WAV or MP3 is the finished audio to play in a music app, attach to a message, or send to someone who does not need to edit it.

Give the files clear names so you can tell them apart, for example interview-edit.tlsound and interview-final.mp3. Store the project and any original audio files together in a folder, then reopen the project before you consider the backup complete.

The Audio Editor works with files in your browser. Your audio files and project stay on your device.
