I’m putting the rest in a separate post - an answer to my own post - because it wouldn’t post the whole thing here, it told me my post was too long!

But it’s this crashing business that’s annoying, cos sometimes when it crashes it takes Windows sound with it so I can’t hear my piece any more. Maybe it’s trying to tell me something about my composing…!!

Yours respectfully,

Chris.

I doubt it’s a memory size/file size problem but I don’t know how to interpret the crash report.

Are you REALLY running Windows NT?

Audacity uses 32-bit floating-point audio and there are 8-bits in a byte so that’s 4-bytes per sample minimum. Plus, the AUP file contains some overhead and undo information which can expand the size quite a bit.

If you have a stereo file with a sample rate of 44.1kHz that would be 4 bytes x 2 channels x 44.1k = 353K bytes per second = 21MB per minute (or larger).

No, that’s Windows 10.

Trebor · July 10, 2025, 3:35pm

a 4 minute file can have hidden depths :
the actual length of the audio therein can be much longer because of non-destructive editing … Smart clips : copy & paste - #10 by steve

A couple of things that can “cause trouble” are 3rd-party plug-ins, or using an external or a network/cloud drive.

Note: Audacity requires fast, uninterrupted access to a hard drive or SSD to operate. Network storage, consumer-grade external hard drives or USB thumbdrives may be unreliable.

pvarn · July 11, 2025, 1:15am

I didn’t see how much memory you have installed but only your CPU spec nor what version of Audacity you are running but I record/edit/play stereo files far larger than 4 minutes at 44.1Khz without crashing on Ubuntu Linux. In addition to the standard Microsoft suggestions below, see if anything changes when you run your system as clean as possible including removing auto starts and hidden applications in your system tray.

The Windows error code 0x40000015, often encountered as “The exception unknown software exception (0x40000015) occurred in the application”, typically indicates an unhandled runtime exception during application shutdown. This can stem from various issues, including corrupted system files, failed updates, or conflicts with other software. Troubleshooting steps often involve checking for corrupted system files, performing a clean boot to identify software conflicts, and potentially updating drivers or the operating system.

Here’s a more detailed breakdown:

Understanding the Error:

The error message “The exception unknown software exception (0x40000015) occurred in the application” suggests that the application encountered an unhandled exception during its termination process.
This can happen due to various reasons, including:
Corrupted system files: Essential files needed for the application to run properly might be damaged.
Software conflicts: Interactions between different programs or services can sometimes cause issues.
Failed updates: Incomplete or corrupted updates can also lead to instability.
Improper shutdown: Abrupt shutdowns can sometimes corrupt system files or settings.
Virus or malware: Infections can also lead to system instability and error codes.

Troubleshooting Steps:

2.1.* Safe Mode:
.

Booting into Safe Mode can help determine if the issue is related to third-party software or drivers. If the error disappears in Safe Mode, it points to a conflict. *
2. Clean Boot:
.

A clean boot starts Windows with a minimal set of drivers and startup programs, isolating the problem software. If the error is resolved in a clean boot, you can identify the conflicting program by enabling services and startup items one by one. *
3. System File Check (SFC):
.

The SFC tool can scan for and repair corrupted system files. You can run it from the command prompt (as administrator) by typing sfc /scannow. *
4. Windows Update:
.

Ensure that your Windows installation is up to date, as updates often include bug fixes and driver updates. *
5. Driver Updates:
.

Update your device drivers, especially for graphics cards and other hardware components. *
6. Consider System Restore:
.

If you have a restore point from before the error started occurring, you can use System Restore to revert your system to that state. * 7. Windows Memory Diagnostic:

.

Check for memory errors that might be causing the issue by using the Windows Memory Diagnostic tool.

Additional Tips:

Check for Viruses:

Run a full scan with your antivirus software to rule out malware as a cause.

Uninstall Problematic Software:

If you can identify a specific application as the culprit, try uninstalling it and see if the error is resolved.

Consider Professional Help:

If you are not comfortable with troubleshooting, consider seeking help from a computer technician
