Hello! Unfortunately, as mentioned in this tool’s page, I couldn’t quite get this extension to work in Libresprite. This is because the way the extension connects to Aseprite has no counterpart in Libresprite.

However! Although I can’t exactly change the extension to fix this, I’ve made a previous version of it – version 1.1.1 – available. This version uses a different method to connect to Aseprite that should work just fine with Libresprite (but is less reliable overall).

This version of the extension is far less reliable, but if you’d like to try it out to see whether it works or not, I’ve made a tutorial on how to set it up.

Hello! Aseprite Audio Extension was made for Windows, as it’s the only platform I have access to. For this reason, it’d be really hard for me to make anything I can somewhat guarantee works on any other platform.

However, if you’re really interested in trying the extension, you can check out its GitHub and run it on your Linux machine via Godot; instructions are in that same link. I cannot guarantee this will work in the slightest.

Hello! HUGE sorry for the long wait! I’ve been juggling projects and it took a while for me to get to this. Have you resolved the issue already?

If not, this might be a codec issue (as noted in other comments), so I advise trying to convert your audio to different file extensions. Do you have any more information about the files you’re trying AAE with if you’re still having trouble?

Hello! Does the extension show it loaded the audio file? If you see the text “No file selected.” it could be that could operating system is messing with AAE. Try running the tool with administrative privileges, this could fix this issue.

Hello! Thanks a ton for posting this! I still can’t believe the extension dies the moment you recommend it (pretty funny, but BIG oops on my part, sorry), but I’ve done some testing and I think I’ve found the culprit.

I tried exporting a test audio with Davinci Resolve and this resulting file crashed AAE. I’m not too sure how or why this happens, since audio loading is handled by Godot (the engine/code framework that AAE is built with), but I did find a workaround.

Reencoding the audio, that is, converting it to a different format (wav for keeping the quality) and back to mp3 fixed the issue for me. I used a local tool I have, but I imagine any online tool should work just fine too.

I’ll look more into it, and I’m glad you also suggested some quality-of-life features like saving the path to the folder. Thanks again for providing such detailed info on your issue!

It is! I forgot to link it here, but the entire source code is available on GitHub. I’m not sure if it works or not on other platforms without changing anything, but you’re free to try it out!

I will help you.
You got this.

Hello! Thanks for trying out the extension, it means a lot to me :)
I think the issue you’re facing with the frame durations might already be fixed in the latest version, so long as you make sure to save your sprite before exporting (exporting processes the saved file, and not the selected sprite).

Oh! Sorry to hear that! I’m not quite sure what may be causing these issues, as audio is loaded by Godot, and not any code I wrote, but what I can recommend is either converting your audios to different extensions (as they may work nicer with Godot) or checking hardware compatibility (although I’m not too sure about that one).

As for your ideas regarding contact, that sounds pretty interesting! I’ll see if I can add any contact info here or in my profile page.

Hello! I’ve uploaded a new version in an effort to fix this. Could you please try it out and reply with an update?

Hello! Yeah! After quite a bit of deliberation, I’ve decided to upload the source code to GitHub. It’s available here!

Not natively, hence why I used Better Processes. It’s a pretty nice addon, I recommend it!

I’ve been juggling quite a few projects lately, but I expect AAE v2.2 to come out within a week or two.

Hello! I’m working on a version that fixes this. The problem arises from the way the expected position the audio should be at is calculated. Until I finish polishing this future version, all I can suggest is standardizing the frame durations. Sorry for the inconvenience!

It’s a feature the extension provides.

Hello! Sorry for the REALLY long delay, but I’ll be working on fixing this as soon as I can, along with a couple of other patches.

Hello! There’s a comment in this page that shows the exact steps to get the path. If these steps don’t work, try running AAE with administrative privileges. If it STILL doesn’t work, please get in contact again.

Hello! I’ll be reworking the sync system as soon as I can. For the time being, please try matching the audio up with external tools, if it’s just an offset problem. Thanks for pointing this out!

I will help you. You got this.

Hey there! I have a hunch as to what might be causing this issue and I’ll try looking into it as soon as I can. For the time being, I can only recommend deleting AAE and the folder “%AppData%/AsepriteAudioExtension/”, and then downloading it again.

Hey there! Unfortunately, this tool relies on some serious Windows wizardry with program IO to work. Reading input/output from other programs is functionality that could be ported to Mac, but as I don’t have any Mac systems at my disposal, I can’t test it out. I suggest looking into programs that let you run Windows applications in Mac (like how Vine works for Linux). Sorry for the inconvenience!

Hey there! If the video turned out completely black, this is likely an issue with the program not being able to save the frames temporarily so it can pack them into one single video. I’d suggest checking permissions to writing to AppData or running the tool with administrative privileges.

It works on my Windows 11 machine, so I don’t think OS is the issue at hand. This is likely an issue with Godot 4, as I’ve received complaints along the same lines on other Godot projects. I recommend checking your drivers and looking for system updates, those can sometimes fix these errors.

The command line output from running AAE via CMD (especially with the –verbose argument) could indicate what the source of the issue is, however. If you don’t mind sharing these details, it could help troubleshoot the issue.

Are you sure the Aseprite path was set up correctly?
It should work on versions that include script support.
The process listed in this page indicates how to do it.

Aseprite Audio Extension v2.1 does not work with Libresprite. The script that AAE uses to hook to Aseprite is built on Lua, and I haven’t yet looked into porting it to JavaScript (used by Libresprite). This may be a feature to be implemented in the future.

It may not be possible to use this extension with significantly older versions of Aseprite. This is due to scripting differences (or the lack of scripts altogether) in these older versions.

Recent versions of Aseprite should work just fine though. What version are you using?

Yeah, I used lower frame durations for testing and the situation is REALLY bad. I’m currently working on another version that patches a bunch of things. Expect an announcement soon :)

Frame duration is an important element at play for this extension to work. If you mean that the audio is stuttering when the duration of all frames isn’t 100, thanks for reporting this! I’m currently working on fixing stuttering related issues.

Do make sure that all frames have the same duration though, as the extension only looks at the current frame’s duration to calculate when to seek the audio to.

This might be a graphic card issue. Try checking your system information against the requirements listed here.

I will help you.
You got this.

Provided you got Aseprite from Steam, you should be able to open up the folder by right clicking Aseprite in your library and going under Manage > Browse local files.

Once you’re in the folder, you can click the empty area next to the address bar and copy that, then add “Aseprite.exe” to the end of the path.

The final result (ending in Aseprite.exe) should be inserted in AAE.

Hey there! Thanks for providing help for this issue! I’ll try to patch up the script copying sometime soon, but thanks a ton for providing your solution already :)

Unfortunately, v1.x is busted. It failed to work on pretty much all devices I tested it on excluding my own computer.
v2.0 should fix this, as it works based on a much more robust and safe method (Lua scripting).

Yup.
I had the idea a few months ago, but due to me working on another project, I kept postponing working on this extension. I did eventually add this on v2.0 though. Thanks for the suggestion!

Yeah. v1.x had a recurring issue of simply not working on multiple devices. I doubt this was related to the Aseprite version, instead I think it’s related to how it used memory peeking on other applications (which is considered unsafe and might’ve been blocked by the OS or anti-virus – with very good reason I might add).
Aseprite Audio Extension has only consistently worked on my machine (running on Intel). v2.0 should fix any issues since it changes the way that the values are accessed (it now uses a Lua script).

Hi there! Thanks for the idea! I’ve been trying to make the extension more user-friendly and I’m pretty confident that v2.0 solves this! I’m not exactly sure if displaying a preview of the audio is possible exactly according to the reference, but other ways of displaying it might be possible. Might look into this in the future, thanks! :)
