Hi Pierre

Thank you for taking the time to look into this issue.
I am confident that I will use TS2 more often now.
Feel free to mark this issue as solved.

Many thanks!

Heinz

Good to know. :-)
I downloaded and installed the new version and tried to reproduce the problem. So far things are looking good. I haven't experienced a crash or freeze from TS2 yet.
Are there release notes for the new version? Any new features, functions?

Many thanks for your quick reply.
I uninstalled v2.2.3 and installed the version you provided.
When I unpack TS-install-2.2.4-dev.zip a folder called TS-install-2.2.4-dev is created. The folder contains a file named TS-install.exe (8.93 MB / 9,103,840 bytes). After the installation and when I start TS2 it still shows TS - 2.2.3 in the top left corner. The About TS information screen shows the same version. Are you sure you provided the correct version?

Regarding process monitor, please don't get me wrong. I've just loaded the sound file and switched to the Process Monitor. TS didn't try to create any temporary files. Instead it tries to read attributes (with success) from the Gong_Test_Preset_18-22_Mix.wav over and over again (forever). If you follow my instruction to reproduce the problem you will see what I mean. This behavior may be unrelated to the cross fade issue. I just wanted to mention it because it looks unusual. If you are unable to use Process Monitor, I can send you some screenshots if it helps.

Many thanks for looking into the issue!

Hi Pierre

Do you have any news on this topic?

Today I had some time to reproduce the problem again.

To get a clue whats going on during the crash or hang I used the Sysinternals Process Monitor from Microsoft.

Reproduction steps:

1. Download and unpack Sysinternals Process Monitor.
2. Start Process Monitor.
3. Press Ctrl-E to stop event capturing.
4. Press Ctrl-X to clear the display.
5. Start TS2.
6. Load Gong_Test_Preset_18-22_Mix.wav I send to you.
7. To capture events generated by TS.exe. In Process Monitor, use the crosshairs (red circles) and drag it or select the TS2 window with it.
8. Press Ctrl-E to start capture events.
9 Press Ctrl-A to set auto scrolling to on.

At this point you should see that TS.exe is producing six events every second (CreateFile, QueryBasicInformationFile, CloseFile..., CreateFile, QueryBasicInformationFile, CloseFile...). Even if the sound is not played or TS2 is not used at all. That looks a bit strange. Like an infinite loop or a thread that runs continuously and never finishes. When you double click on a specific event, you can view the event properties like process tree, loaded modules, and the stack.

10. Switch to the TS2 window and split Gong_Test_Preset_18-22_Mix.wav into 5 regions.
11. Set the crossfade length for each region to one third of the region.
12. Move the regions and start cross fading.

At this point, TS2 begins to lag or hang. CPU usage stays at around 50%. When it hangs, TS.exe generates millions of ReadFile events every few milliseconds in the process monitor.

If you have any question or an advice please let me know.

Hope this helps.

Heinz

Hi Pierre

I'm sorry to inform you that, after more intensive testing, the developer TS2 version also crashed.

I was able to set, move and adjust about five crossfades without any problem.
The crash occurred after I changed the stretch factor and remix parameters. Then I tried to adjust and move the crossfade regions again. TS2 closed unexpectedly.

If it helps, I can do more testing tomorrow.

When TS2 crashed, the following event log entry was written. According to MS, a C0000005 is a memory error (an access violation error caused by a buffer overrun).

Hi Pierre
Thank you for sharing the development version.
I downloaded the file and tried to reproduce the problem.
So far things are looking good. The problem seems to be solved.
Good work. Thanks very much!
Heinz

Thanks for the information.
I removed the share to the file.
I hope you don't mind.

Hi Pierre

Here you will find the link to the information you requested. Please let me know when you downloaded the file (Crossfade_Issue.zip, 45.7MB).

Today I tried to reproduce the issue at 44.1kHz. The problem remains the same.
I tried different buffer sizes also, e.g. 512, 1024. 2048 and adjusted the buffer size of the audio interface accordingly.
It didn't help either. When I played the audio file without reproducing the problem, I heard no artifacts or glitches.

Last but not least I used a different mouse and a different mouse driver. Without succes.

Btw: The USB audio interface I use is a Motu M4. Firmware and drivers are up to date.

I will not use the TS2 crossfade function for the time being.

I look forward to hearing from you.

Many thanks!

Heinz

I tried many things today to find the possible cause of the problem. Unfortunately without success.

TS2 freezes continuously when moving the crossfade area. After trying a lot of times, I ended up having another crash caused by TS.exe in ModuleName ntdll.dll (ExceptionCode c0000374).

According to Microsoft Code 0xC0000374 is a STATUS_HEAP_CORRUPTION (a heap has been corrupted.)

To rule out system file corruptions, I ran the Win11 system file checker from an admin command prompt (cmd):

DISM.exe /Online /Cleanup-image /Restorehealth

The operation completed successfully without errors..

I then used the System File Checker tool to check for or repair missing or corrupted system files:

sfc /scannow

Verification 100% complete. Windows Resource Protection did not find any integrity violations.

The Windows version I'm running is up to date and none of the usual checks for corruption has indicated a problem ( system file checker, dism ).

I have no problems or crashes with other audio apps or windows applications in general (but actually I prefer Linux :-).

Thank you for taking the time to investigate the issue!

Unfortunately, the problem occurs with every audio file I load.
I tried to track down the problem using Sysinternals Process Monitor.
The only thing I've noticed so far is that TS2 keeps trying to create temporary files in the following folder C:\Users\%username%\AppData\Local\Temp\Documents (e.g. Document_a8a5c88870894197bd91384605729520.tsdoc). This behavior seem to stop as soon as the freeze stops.

Many thanks for the hint! I tried it out but the issue happened again.

Many thanks for your quick reply!

I'm afraid it will be difficult to send you the consolidated document because the max. single upload file size is 10MB.

Let me explain what I tried so far:

- I moved the *.wav files to a faster disk (NVME drive).

- I uninstalled and reinstalled TS2 v2.2.3 from scratch.

To reproduce the crossfade issue I used the default TS2 v2.2.3 settings after the fresh install.

I loaded one *.wav file with 50MB in size.

I've split the file into two regions. Did the fade out on the first region, the fade in on the second region and joined the two regions together to do the crossfade.

Interestingly the issue is behaving slightly different now. TS2 is not crashing anymore. Instead, during the crossfade, TS2 freezes completely. When the freeze occurs TS2 shows a CPU utilization of 1%. The mouse or keyboard shortcuts are not working anymore. Windows task manager shows a CPU utilization at around 50% for TS.exe. I'm still able to use other programs when TS2 hangs. Sometimes TS2 stops from freezing but the crossfade is completely messed. When I try to do the crossfade a second time, TS2 hangs again.

If there is any possibility to debug the issue I'm glad to assist to track down the cause of the problem.

Many thanks!
