Preview Build Discussion / [Bug] Library refreshes to default view after user has scrolled downwards

« on: May 21, 2026, 12:33:37 PM »

When viewing your library, if you scroll downwards some arbitrary amount and then leave WACUP idle for some indeterminate time, the library will "auto-refresh" and revert the view back to the top of the list. Unsure how much exact time this takes, but it's not long, maybe in the realm of 30-ish seconds.

Repro steps:

• Open library
• Ensure search is empty so view is at default
• Scroll down through your library
• Stop at a random location
• Wait, and observe WACUP

Result: Library will revert view back to the top of the list after some time

Preview Build Discussion / [Bug] Edited metadata regresses to previous values, "update file tags" fails

« on: May 09, 2026, 03:33:23 PM »

When updating some mp3's metadata, it appears successful, but any subsequent edits to the same file metadata will regress previous edits. Additionally, some files will regress by themselves over time, effectively going back to previous metadata. It's unclear what causes this "timed" regression.

Selecting "Update file tags" checkbox in the metadata editor will give a "Metadata updating error" box, but it is unclear what causes this to fail, when other mp3 files will update their metadata correctly.

Worth noting that these same files can be successfully edited in other software such as mp3tag.

Screenshot show the metadata successfully changed in Wacup but not in the file metadata seen in explorer.

Repro steps:

• Right click a file in library
• Go to "edit metadata for selection"
• Ensure "update file tags" is UNCHECKED
• Edit the track name to something else
• Click update
• Track name appears to change
• Repeat steps but change the album title this time
• Album title updates, but track title will regress to before the above edit
• Open metadata editor again
• Ensure "update file tags" is CHECKED
• Change any metadata and click update
• Update fails

Preview Build Discussion / [Bug] Ableton .asd files cause WACUP to lose metadata from .mp3 files

« on: March 31, 2026, 10:04:24 PM »

Ok this is a good one! When adding an mp3 (or any other audio file) into an Ableton project, there is an option to generate an .asd analysis file alongside it, which is basically a waveform editing reference file. https://www.ableton.com/en/live-manual/12/managing-files-and-sets/#analysis-files-asd

These are generated next to the audio file, an example is importing MUSIC.mp3 into Ableton will generate a MUSIC.mp3.asd file in the same directory. Annoyingly, Ableton does not provide an option to generate the .asd files in a custom location, which means they end up scattered in random folders across all your drives.

The bug here is that any mp3 files which have an accompanying .asd will fail to load correct metadata into WACUP. The screenshot shows a ton of mp3s I dragged into an Ableton project a few days ago for a performance over the weekend, which are now missing lots of metadata which existed prior to the Ableton project. Opening WACUP today I noticed this bug. The strange thing is about 4-5 of these tracks have very old .asd files from months ago, but only generating the new .asd files on the latest Ableton project a couple of days ago triggered this bug. (Had to censor the screenshot due to lots of unreleased material here, sorry.)

Repro steps:
1. Ensure you have mp3 tracks added to your WACUP library and they appear with correct metdata
2. Open an Ableton session
3. Ensure Ableton option are set to generate .asd files
4. Drag one of your mp3s into Ableton and wait for waveform to fully generate
5. Save the project
6. Restart WACUP (I guess?)
7. Observe broken metadata on the file you dragged into Ableton

The real fix here is to pester Ableton to give us a custom .asd folder the same way Reaper does for it's analysis files, so they are not randomly scattered across every single folder on your computer, but people have been requesting this for like 15 years if you dig through old Ableton forum threads

Preview Build Discussion / [Bug] Equalizer plugin does not remove low frequencies <300Hz

« on: March 24, 2026, 11:56:58 PM »

Setting the EQ to remove anything under 300Hz doesn't really seem to have any effect. I've provided two screenshots, one has no EQ with a full spectrum visible, the other screenshot has the EQ entirely rolled off under 600, but the effect only seems to scoop the mids. Anything under around 300-200 start to become drastically audible again, with the lowest frequencies almost unaffected. There is a mild reduction in the lows/subs, but nothing even close to what the EQ should be doing at these settings.

I've tested this behaviour on the high end and roling off high freqs does seem to work as intended.

Repro steps:

1. Play some music
2. Open the EQ
3. Roll off everything at 320Hz and lower
4. Use a spectrum analyzer (or your ears) to observe no change in low end

Resolved Issues / [Bug] Searching library with blank space " " returns incorrect/broken files

« on: March 24, 2026, 02:04:22 PM »

Adding a blank space " " in library search will return a list of incorrect files, pulled from various locations on the computer, including outside of the designated library folders. In my case, Winamp is only set to watch D:/Music but a blank space search returns audio files from my Windows User Desktop & Downloads.

In addition, some library files are displaying broken or missing metadata, but only when returned via a blank space search. If I search those same audio tracks normally, eg. "artist name" in search, then the metadata appears correctly in the library.

Sorry I can't provide a good screenshot of this one, but the results in my Desktop and Downloads are private. It's an easy repro to try yourself tho.

Repro steps:

1. Go to library
2. In the search box, type a blank space with spacebar
3. Observe library results from incorrect locations and broken metadata

The attached screenshot does show a blank space search (obviously invisible) returning 52 tracks missing Genre and 43 tracks missing Artist, but under normal searches and at a default no search state, no item in my library is missing these data. I'm not yet sure what is determining which files appear broken under a blank space search.

Preview Build Discussion / [Bug?] Context menu "show all by artist" does not work when filters are active

« on: March 24, 2026, 01:46:47 PM »

Hey there,

These one seems like a bug but may be intended behaviour. However if the latter, it's very unintuitive and not great UX.
Filtering by an album and then using the library context menu to "show all by artist NAME" does not override the search filter.
The terminology of "show all by artist NAME" implies I see everything by that artist, with the album filtering removed.
Untested with other filters such as "genre" but I'd expect the same behaviour.

Repro steps:

1. In library, use the "Album" filter to select an album
2. In library panel, while only viewing the selected album, right click any track
3. Select "show all by artist NAME"

Actual result:

The search bar is populated with the string "?artist="ARTIST NAME" " but the results in the library are still filtered by the original album filtering, therefore hiding any results not in the currently selected album.

Expected result:

In repro step 3, the album filtering should be removed, and ALL tracks by artist should be displayed, as implied in "show all by artist NAME"

Preview Build Discussion / [Bug] New media items added to library will appear with missing metadata

« on: September 24, 2025, 01:14:17 PM »

New media items added to library via a monitored folder will appear with missing metadata until the metdata is edited. The "missing" metadata actually appears to be in place, but just does not initially appear in the library. This seems to affect some of the newly added files, while some appear with the correct metadata in the library.


Repro steps:

1. Go to Preferences > Media Library > Folder Monitor
2. Ensure a folder is being monitored and all options are enabled, such as real time monitoring
3. Add a new folder to the monitored location, which contains some mp3s with correct metadata
4. Wait for the library to auto-scan, or restart WACUP to trigger a scan
5. SOME of the new media items will appear as blank entries at the top of the library
6. Right click a blank entry, and "Edit metdata"
7. Click in any field and then click "Update" (You don't need to actually change any values)
8. The media will now appear with correct metdata in the library

In the screenshot attached you can see three entries of a folder I added, two of them are missing metadata while one track appears correctly (censored as it's unreleased!). This occurs with every folder I add.

Resolved Issues / [Feature Request] Clear Discord rich text presence when music is paused

« on: September 03, 2025, 06:55:03 PM »

Currently if you pause a track while sending RTP info to Discord, Discord will show that the track is continuing to play indefinitely.

The track must be stopped rather than paused. It would be great if pausing a track also cleared the Discord RTP info, or if there was at least an option to toggle this behaviour, similar to the option to toggle the Stop behaviour.

Preview Build Discussion / [Bug] Tags including the Polish character "ł" are randomly regressing to "l"

« on: August 29, 2025, 01:33:33 PM »

Mp3 tags which include the Polish character "ł" are randomly regressing to the English "l", most notable when Polish "ł" is included in more than one tag, eg. song title and album title.

Repro steps:
1. From the library view, open "Edit item metadata" window on an mp3
2. Change the song title to something including "ł" (eg. "hijkłmno")
3. Change any other field to the same title, eg. artist, album artist, album name, etc.
4. Click Update

Expected result:
All fields should maintain the new titles

Actual result:
One of the fields with "ł" will regress to the English character "l"

Skins / Scaling doesn't affect library text

« on: August 21, 2025, 02:35:26 PM »

Hey, sorry if I'm missing something really obvious, but changing the scaling settings on Big Bento & Big bento Modern W10 doesn't actually affect the main text in the library panes. This leaves me with some elements which are scaled, but tiny text in the library which remains difficult to read at smaller resolutions.

I haven't seen any clear instructions on previous posts on how to change the font sizes, or why in my case they are not linekd to the skin scaling. The option in the "Font Rendering" tab aren't clear to me, eg. "sking font mapper" and "truetype replacement" etc.

Preview Build Discussion / [Bug] Closing the "Edit metadata" window refreshes the audio library view

« on: May 31, 2025, 12:33:43 PM »

As per title, closing the "Edit metadata" window refreshes the audio library view

Reproduction steps:
1. Open audio library
2. Scroll or search to a track in the middle of the library
3. Right click track and "Edit metadata for selection"
4. Click "Cancel" or "Update"

Result: Audio library refreshes and goes back to the top

This is awkward when, for example, editing track titles on multiple files. You need to search/scroll back to the album every time

Preferred result: the audio library window does not refresh when closing "Edit metadata" window

General Discussion / Importing Local Library .csv

« on: April 18, 2025, 02:59:46 PM »

Hey there, I've started using WACUP and it's amazing.

I'm a bit confused about the library import/export. I can export my local library to a .csv file but I can't find and option to import that same .csv.

On Winamp I could export to an xml, make edits, then reimport that xml. Is there a way to do this on WACUP?

Thanks for all the great work!
